Searching SQL Db And Returning Results To Gridview

Hello....

I am in the process of building a search function for an application (VS2005, ASP.net, VB code, and AJAX functionality).The user's form has a textbox (for an input string) and two drop-downs.  The user would then click on a "Search Now" button, and the data should populate
in a Gridview to the left of the search form.  I'm trying to search over an SQL database and need to know how to exactly implement what I have so far:

<div id="mcb" style="background-color:#2e4b5b; width:195px; height:410px; float:left">
     <div id="ht" style="background-color:#1b2c36;padding:10px; border-bottom:solid 1px #fffdff; width:175px;float:left;">
           Quick Search
     </div>
<div style="clear:both;"></div>

<div style="padding:10px; background-color:#2e4b5b">
      <div id="tfta" style="padding:5px 0px 0px 0px">
                <b>Vendor Name</b>
                <asp:TextBox ID="txtVendorFilter" runat="server"></asp:TextBox>
                <div style="font-size:1px; width:150px; height:1px; background-color:#8FA71F"></div><br />
                 <b>Contract Type:</b>
                 <asp:dropdownlist ID="ddlContractTypeSearch" runat="server" Width="155px">
                           <asp:ListItem Value="0">Select...</asp:ListItem>
                           <asp:ListItem Value="1">Vendor Maintenance</asp:ListItem>
                           <asp:ListItem Value="2">Consulting Contract</asp:ListItem>
                           <asp:ListItem Value="3">Hardware License</asp:ListItem>
                           <asp:ListItem Value="4">Software License</asp:ListItem>
                           <asp:ListItem Value="5">Statement of Work</asp:ListItem>
                           <asp:ListItem Value="6">Admin Svcs. Agreement</asp:ListItem>
                           <asp:ListItem Value="7">Master Service Agreement</asp:ListItem>
                  </asp:dropdownlist>

           <div style="font-size:1px; width:150px; height:1px; background-color:#8FA71F"></div><br />
                   <b>Sort By:</b>
                   <asp:DropDownList ID="ddlSortBy" runat="server" Width="155px">
                          <asp:ListItem Value="0">Select...</asp:ListItem>
                          <asp:ListItem Value="1">Contract Name</asp:ListItem>
                          <asp:ListItem Value="2">Contract Type</asp:ListItem>
                    </asp:DropDownList>             <div style="font-size:1px; width:150px; height:1px; background-color:#8FA71F"></div><br />
        </div>
    <br />
    <asp:Button ID="btnUpdateFilter" runat="server" Text="Search" width="120px"/>
    <asp:Button ID="btnReset" runat="server" Text="Reset" /></div>

</div>

 Here's my select statement used to initially populate the Gridview (set up using the configuration of the Gridview):
SELECT [ContractID], [ContractName], [ContractType], [EffectiveDate], [TerminationDate] FROM [Contract]
Here's my btnUpdateFilter codebehind (VB):


Protected Sub btnUpdateFilter_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateFilter.Click
     Dim strVendorName As String
     Dim strContractType As String
     Dim strSortBy As String

     If txtVendorFilter IsNot "" Then
           strVendorName = txtVendorFilter.Text
     End If

''''''''''''''''''''''''''''
If ddlContractTypeSearch.SelectedValue = 1 Then
      strContractType = "1"
ElseIf ddlContractTypeSearch.SelectedValue = 2 Then
      strContractType = "2"
ElseIf ddlContractTypeSearch.SelectedValue = 3 Then
      strContractType = "3"
ElseIf ddlContractTypeSearch.SelectedValue = 4 Then
      strContractType = "4"
ElseIf ddlContractTypeSearch.SelectedValue = 5 Then
      strContractType = "5"
ElseIf ddlContractTypeSearch.SelectedValue = 6 Then
      strContractType = "6"
ElseIf ddlContractTypeSearch.SelectedValue = 7 Then
      strContractType = "7"
Else
      strContractType = "0"
End If

''''''''''''''''''''''''''''''
If ddlSortBy.SelectedValue = 1 Then
     strSortBy = "ContractName"
ElseIf ddlSortBy.SelectedValue = 2 Then
     strSortBy = "ContractType"
Else
     strSortBy = "ContractName"
End If

End Sub

 

My question is, "how can I form the proper SQL statement", and then implement it so that my gridview will populate using my generated SQL Statement?

Thank you for the help!!!

Want Error Message To Appear When No Database Results Were Returned In GridView, Also Other GridView Issues.

Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having.   Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class  I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!

Mind-boggling Gridview Results! Different Results For Different Teams..

Hi all, I have the following SQLDataSource statement which connects to my Gridview:<asp:SqlDataSource ID="SqlDataSourceStandings" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"  SelectCommand="SELECT P.firstName, P.lastName, T.teamName, IsNull(P.gamesPlayed, 0) as gamesPlayed, IsNull(P.plateAppearances,0) as plateAppearances, IsNull( (P.plateAppearances - (P.sacrifices + P.walks)) ,0) as atbats, IsNull(P.hits,0) as hits, P.hits/(CONVERT(Decimal(5,2), IsNull(NullIF(P.atbats, 0), 1))) AS [average], (P.hits + P.walks)/(CONVERT(Decimal(5,2), IsNull(NullIF( (P.atbats + P.sacrifices + P.walks) , 0), 1)))  AS [OBP], (P.hits - (P.doubles + P.triples + P.homeRuns) + (2 * P.doubles) + (3 * P.triples) + (4 * P.homeRuns)) / (CONVERT(Decimal(5,2), IsNull(NullIF(P.atbats, 0), 1))) AS [SLG], P.singles, P.doubles, P.triples, P.homeRuns, P.walks, P.sacrifices, P.runs, P.rbis FROM Players P INNER JOIN Teams T ON P.team = T.teamID ORDER BY P.firstName, P.lastName"></asp:SqlDataSource>There are 8 teams in the database, and somehow the average and obp results are as expected for all teams except where T.teamID = 1.  This doesn't make sense to me at all!  For example, I get the following results with this same query: First NameLast NameTeamGPPAABHAVGOBPSLG1B2B3BHRBBSACRRBI

Returning HTML Via SQL To Bind To A Gridview



So I have a stored procedure that returns rows that look similer to this


<a href="~/Manage/ManageVersion.aspx?viewstate=MTgwNywzMTc0LDguOSAgICAgICA=">DPF-13</a>

Unfortunatly when it is bound to the gridview it seems to convert the value to HTML safe.

The value it prints on the page is


&lt;a href=&quot;~/Manage/ManageVersion.aspx?viewstate=MTgwNywzMTc0LDguOSAgICAgICA=&quot;&gt;DPF-13&lt;/a&gt;



Hit quote to look at the actual values


How can I fix the output to the gridview to print the actual link and the the html safe value?

Can I accomplish this in SQL or am I going to have to do it all in the c# code (which will be a less clean solution and alot more work).

Searching Relations And Returning Them In A Table

Getting Results With Stored Procedure From Single Textbox Searching Table With Multi Columns

I admit I am a novice toqueries and stored procedures but understand stored procedures are more secure, so I am choosing to challenge myself with a stored procedureand have not been successfulat all.

What I am looking for is a stored procedure which would query the single table named Hospital, which would search from a single textbox the end user would enter the text they are searching for on a Windows VB application but is dependant on a few end user selecteditems.

1. The end user can select a radio button either "Starts with" or "Contains"
2. The end user can select from 6 checkboxes (Hospitals, Address, City, State, Zip, Type) to limit or expand their search from the columns in the table.

The table has 17columns (CO, PARENTCO, ADDR, POBox, CITY, State, ZIP, TEL, FAX, WEBSITE, HOSP_TYPE, OWNERSHIP, BEDS, CONTACT, TITLE, Email) but I am only allowing the end user to search by the above 6 columns and need to display the above 6 columns plus the phone, fax and website columns.


After the user clicks the search button it displays the results in a listbox and the user will then select the one they want and it displays the information in another set of textboxes.

Hopefully someone can get me pointed in the right direction! Thanks for your help!

Returning The Results Of A Linq Query

I need some help. I have a function that used to use ADO.NET to return a dataview. Now I'm using linq, and I don't know how to make this work anymore.my original function looked like this:    public DataView getIssue()    {       //do some ADO, return the dataview       return ds.Tables["Articles"].DefaultView;    }  With this I could write Gridview1.dataSource = getIssue();I want to do the same thing with Linq, but I'm running into some trouble:Here's my function now:public DataView getIssue()    {        var query = from a in db.Articles        join i in db.Issues on a.IssueID equals i.IssueID       select a;            DataView dv = new DataView();            dv = query.asdatatable();        return query;    }OK, first off I can't use asdatatable since I am using a join, so I can't make the results of my query a dataview. I can't return the results of my query in this function, something that seemed simple to do in Linq now seems like something that may only be possible in ADO.Thanks for your time

OpenXML Not Returning Desired Results

Hi all,I have a SQL job where I do the following -I check for new rows in my Table "DumpResults", every now and then and get the new rows to be inserted into table "CleanTable". I use OPENXML() to get the new data to be inserted but for some reason I don't get the right data through OPENXML() - DECLARE @intDoc INTDECLARE @xmlDoc VARCHAR(8000)IF(SELECT COUNT(*) FROM DumpResults WHERE DumpResults.C1 NOT IN (SELECT CleanTable.C1 FROM CleanTable)) > 0BEGINSET @xmlDoc = (SELECT * FROM DumpResults WHERE DumpResults.C1 NOT IN (SELECT CleanTable.C1 FROM CleanTable) FOR XML RAW) SET @xmlDoc = '<TABLE>' + @xmlDoc + '</TABLE>'
PRINT @xmlDocEXEC sp_xml_preparedocument @intDoc OUTPUT, @xmlDoc--INSERT INTO CleanTable(C1, C2, C3, C4, C5)
SELECT C1, C2, C3, C4, C5, C6 FROM OPENXML(@intDoc,'/row',1)WITH (C1 INT, C2 CHAR(3), C3 CHAR(3) , C4 FLOAT, C5 INT)EXEC sp_xml_removedocument @intDoc
END
ELSE Output that I get is - <TABLE><row C1="1" C2="AAA" C3="BBB" C4="1.000000000000000e+000" C5="2"/></TABLE>(0 row(s) affected) SO "PRINT @xmlDoc" is returning back the xml data (new results) it collected from the "DumpResults" table which isn't there in "CleanTable" but the "Select... FROM OPENXML(...)" doesn't return any result. why so? If anyone knows please reply If anyone has any better method to do it, inputs are welcome. Thanks

SqlDataReader Returning Incorrect Results

I am/have been having an issue with Data Access from a Sql Server database. I have a class that contains a method called "GetDataReader" which takes in a string for the query. Occasionally, the DataReader returned has completely different columns thus resulting in an error when trying to read the data. Below is a small section of code that actually creates the datareader, opens the connection and executes the reader.SqlCommand cmdReader = new SqlCommand();
SqlDataReader drReturn = null;
try {
// Set the connection for the command object
cmdReader.Connection = new SqlConnection(this._csbGlobal.ConnectionString);
cmdReader.Connection.Open();
// Set the command type
cmdReader.CommandType = Type;
// Set the command text
cmdReader.CommandText = Sql;
// Set the command timeout
cmdReader.CommandTimeout = _iTimeout;
if (Parameters != null) {
// Set the parameters
for (int i = 0; i < Parameters.Count; i++) {
cmdReader.Parameters.AddWithValue("@" + Parameters.GetKey(i), Parameters[i]);
}
}

// Get the return value
drReturn = cmdReader.ExecuteReader(CommandBehavior.CloseConnection);
// Dispose of the command object
cmdReader.Dispose();
cmdReader = null;
} catch (SqlException e) {
this.HandleError(e);
} catch (Exception e) {
this.HandleError(e);
}
// Return the reader
return drReturn;The data access class is created on each page and only used for that page and any usercontrols on that page. I have checked all the datareaders and they are all being closed. I have been fighting with this issue for about a month and a half now. It only seems to happen when there are a lot of people on the site.If anyone has experienced this or konws how to fix it please let me know. Thanks-Jason

Executing A Script And Returning The Results..

You know how osql can return the results of executing a .sql script to a window? Is there any way to achieve that same behavior in .NET? I am in the process of working on an application that needs to execute a .SQL script (which is easy to do) and then return the actual SQL output from the execution to a window. How do I get that output? None of the sql data objects seem to support this.

Returning Results While The Query Is Executing

Hi,I wanted to know if this is possible and if so, how do Ido it. Say, I have a query "SELECT * FROM Table WHEREColumn="some_value". This executes on a very large dataset and I would like to return the results as they queryexecutes rather than wait for the whole query to execute.Basically, I want to get the results as they are preparedby the database. Any way to do this?Regards,San

Query With Parameters Not Returning Right Results

I havea 2 part issue with a query I'm trying to run for a report.

I have an incident report that needs to show results based on dates from the week before. In addition, This report should run every Monday morning, with the exception of a Monday holiday, where in that case, the report will run the next business day. I have an idea to use a case statement, but it doesn't seem to work for me. Any suggestions?

Also,part of the query I have is pulling back the right data, as long as I don’t include parameters. When I do add values to the parameters the query includes all the dates. I need to see either/or - not both. I just want to either see dates without the param values or see only dates that I ask for in a parameter. Does that make sense?

Here’s the query (thanks!):

SELECT incident.incid_id,
incident.incid_short_desc,
incident.incid_received_date_time,
incident.incid_closed_date_time,
security_users.description,
incident.incid_assigned_to,
incident.tagged_delete_flag,
activity_result_master.result_desc,
incident_priority_master.priority_desc,
activities.result_id

FROM activities AS activities INNER JOIN

Sql Query Not Returning Correct Results From Db

Hello.

I am new at SQL and am using SQL server express edition and im a bit stuck! I am using ASP.NET and C# in my website which is using sql database back end.

String SQLroom = "SELECT DISTINCT RoomName FROM Room INNER JOIN RoomCalendar ON Room.RoomID = RoomCalendar.RoomID WHERE Capacity = '" + reqCapacity + "' " + " AND NOT ('" + newRoomEnd + "' <= roomStartDateTime OR '" + newRoomStart + "' >= roomEndDateTime) AND (OHP = '" + ohpYesNo + "' AND AV = '" + avYesNo + "') ";

This is my SQL string... what it is trying to do is:

find the room
where the capacity is the reqcapacity entered by user
and the startdatetime and enddatetime entered by the user are not present in the table for that room capacity
and then look at whether the user requires OHP or AV facilities, which are stored in the database as either yes or no values.
The problem i am having is with the condition in the sql query... because the user may require an OHP and not AV, but then the room returned "`could" have AV facilities, as it wouldnt make a difference to them if it was there or not, basically, the yes condition has to be satisfied.

Not sure whether i should be using AND, or OR? or a combination.

Any ideas gratefully appreciated....

Containstable Not Returning Accurate Results



Does anyone lese get the same results that I do?

tblTest has an id field and a testName field....table has 2 records:
1 kevin test 1
2kevin test 3


SELECT *

FROM tblTest t

INNER JOIN CONTAINSTABLE(tblTest,*,'"kevin test 1"') as A ON t.id = A.[KEY]

Result isboth records returned, but since the search is in quotes as an exact phrase, should not just the first record be returned?

Why Is This JOIN Statement Not Returning The Right Results?



Hi,
I have three tables:
1 Order Details
2 Product Info
3 Received Qty


The query is pretty simple however I'm getting incorrect results.

The query grabs a load of information (including a SUM statement) from the order details tbl.. this is INNER JOIN ed to the products tbl to match an ID field which grabs some extra info from theproduct info tbl.

all fairly straightforward and works without a problem..

However I now need to add in the received qty tbl (as the name suggests this keep a track of the qty's of items received)

I need to join this tbl to the order details tbl based on a unique ID from the orders tbl and then SUM together all of the entries in that received qty tbl for that item.

Result is I get a single record which shows the qty ordered (from the order details tbl), and the total received (from the received qty) tbl

These are held in a seperate tbl as an order can be deliveryed in several stages.



Here is my statement:

SELECT PDS_Login.Supplier_Products.ProductName, PDS_Login.Supplier_Products.ProductCode, dbo.Suppliers_POs_Details.POID,
dbo.Suppliers_POs_Details.PODetailsID, dbo.Suppliers_POs_Details.Qty, dbo.Suppliers_POs_Details.PricePerItem,
dbo.Suppliers_POs_Details.PoDetailsStatus, dbo.Suppliers_POs_Details.PoDateExpected, dbo.Suppliers_POs_Details.PODateReceived,
SUM(dbo.Suppliers_POs_Details.Qty * dbo.Suppliers_POs_Details.PricePerItem) AS LineTotal, SUM(dbo.Suppliers_POs_Details_Received.Qty)
AS QtyReceived
FROM dbo.Suppliers_POs_Details INNER JOIN
PDS_Login.Supplier_Products ON dbo.Suppliers_POs_Details.ProductID = PDS_Login.Supplier_Products.ProductID LEFT OUTER JOIN
dbo.Suppliers_POs_Details_Received ON dbo.Suppliers_POs_Details.PODetailsID = dbo.Suppliers_POs_Details_Received.PODetailsID
WHERE (dbo.Suppliers_POs_Details.POID = @POID)
GROUP BY dbo.Suppliers_POs_Details_Received.Qty, PDS_Login.Supplier_Products.ProductName, PDS_Login.Supplier_Products.ProductCode,
dbo.Suppliers_POs_Details.POID, dbo.Suppliers_POs_Details.PODetailsID, dbo.Suppliers_POs_Details.Qty, dbo.Suppliers_POs_Details.PricePerItem,
dbo.Suppliers_POs_Details.PoDetailsStatus, dbo.Suppliers_POs_Details.PoDateExpected, dbo.Suppliers_POs_Details.PODateReceived,
dbo.Suppliers_POs_Details_Received.Qty


The problem is, if there is more than one relating record in teh Received Qty tbl instead of that being added together as I want, two results appear...

It's obviously something simple but I can't seem to figure it out - anyone point me in the right direction?

TableAdapter/DataTable Query Returning No Results

Hello,
I have a query that works in query analyzer; it looks that a certain date is between the start and end date of a certain value.  I also have a status field, which can be null, but if provided, provides the appropriate status to filter by.
Again, the query works in QA, but not in the application.  I test in SQL by using start date = '1/1/1900', end date = '12/31/9999', and status = null.  Results are returned.  But, not when the results are done through code.  In code, I set the begin date to new DateTime(1900, 1, 1), the end date to DateTime.MaxValue, and the status to a null string.  But, no results are returning.  Why isn't that mapping over correctly?  In the function, it has the two dates as Nullable(Of DateTime), which I provide a date, and the string is getting passed Nothing.
Any ideas?  Can't post any code on this one...
Thanks.

Procedure/Cursor Question About Returning Results

I'm working on a procedure that needs to cycle through the records of some raw data and combine the the current record with the datetime field of the prior record. I have been able to write a script to do that with cursors and variables but my problem is it returns each record separately. How do I go about getting the procedure to return all the records as one set of data?

To see what I mean, the following script for the Pubs DBreturns each pass through the data as a seperate query. Since I can't do a select *, what approach should I take? If you want the actual script, I would be happy to provide it.

DECLARE authors_cursor CURSOR
FOR SELECT * FROM authors
OPEN authors_cursor
FETCH NEXT FROM authors_cursor

WHILE @@FETCH_STATUS = 0
begin
FETCH NEXT FROM authors_cursor
end

Close Authors_cursor
deallocate authors_cursor

Thanks in advance

Returning Multiple Results From A Cursor Into A Table

The problem I'm having is that I need a cursor to return multiple results into 1 .NET System.Data.DataTable, and I don't know if it's possible. Actually, the real problem I'm having is that whoever designed this database did a poor job and if it weren't for one small thing I could do this all with aggregates...

But more specifically, this is what I need to accomplish. I have written a cursor that I know works - when I run it in MS SQL Query Analyzer, I get the results I want, but it's returned in multiple tables. I am maintaining a .NET application with some pretty lousy performance and I'm trying to boost it up. I need to take the cursor's results, stuff them into a DataTable, and then return that table to my web application to render.

In my C# code, I am using a SqlDataAdapter to execute my query. This is what I'd like to do...





/*assume query is my working cursor, InvoiceDBConnection is not null, and dt is an empty, non-null DataTable*/

SqlDataAdapter sda = new SqlDataAdapter(query, InvoiceDBConnection);
sda.Fill(dt);

... but this doesn't work, and it makes sense, I guess...since the cursor returns multiple "tables" (not sure if that's actually how the data is returned).

So is there any way to accomplish what I want to do? Or do I have to do it the crappy way it's done now by running my aggregate query and then using a really time-consuming for loop on my results to make the necessary adjustment?

Any help is greatly appreciated

SqlDataSource And SSMSE Returning Different Results For Same SELECT Command

Hi,
Hope you guys won't mind this rather newbie question.  I'm writing a simple blog page for my website and have created a SqlDataSource which queries the database for a list of blog post titles (from the web.Blog table) and the number of comments (from the web.BlogComments table).  The SqlDataSource control is:
<asp:SqlDataSource ID="sourceBlogArticles" ProviderName="System.Data.SqlClient" connectionString="<%$ ConnectionStrings:myDatabase %>" runat="server" SelectCommand="SELECT gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded, COUNT(gbc.blogID) AS noOfComments FROM web.Blog gb LEFT OUTER JOIN web.BlogComments gbc ON gb.blogID = gbc.blogID GROUP BY gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded ORDER BY gb.dateAdded"></asp:SqlDataSource>
This works perfectly well if each blog entry in the web.Blog table has associated comments in the web.BlogComments table.  However, if there are no comments yet defined in the web.BlogComments table for that blogID then no row is returned in ASP.Net (as checked with a GridView control or similar linked to the data source to view what I get)
 HOWEVER, I think the SELECT command IS correct: if I use the select command as a query in SQL Server Managment Studio Express, I do get the rows returned, with 0 for the number of comments which is what I would expect for that query:
blogID, title, description, tags, dateAdded, noOfComments
1, title 1, description for title 1, tag1, 2007-09-27 06:49:03.810, 32, title 2, description for title 2, tag2, 2007-09-27 06:49:37.513, 03, title 3, description for title3, tag3, 2007-10-02 18:21:30.467, 0
Can anyone help?  The result from the SSMSE query is what I want, yet when I use the very same SELECT statement in my SqlDataSource I don't get any rows returned if the BlogComment count is zero (in the above example I get only the first row).  Many thanks for any suggestions!

Returning Results Left Outer Join With Conditions

I have a SELECT Statement that I am using that is pulling from two tables.  There won't always be results in the second table so I made a LEFT OUTER JOIN.  The problem I am having is that I need to have three conditions in there:WHERE (employee.emp_id = @emp_id) AND (request.requested_time_taken = 'FALSE') AND (request.request_end_date >= GETDATE()))The two conditions from the request table are causing the entire query to return NULL as the value.  I need help trying get a value whether or not there are any results in the request table.Here is the full select statement:SELECT (SELECT SUM(ISNULL(request.request_duration, '0')) AS Expr1
FROM employee LEFT OUTER JOIN
request AS request ON employee.emp_id = request.emp_id
WHERE (employee.emp_id = @emp_id) AND (request.requested_time_taken = 'FALSE') AND (request.request_end_date >= GETDATE()))
AS dayspending
FROM employee AS employee_1 LEFT OUTER JOIN

Select Script Returning Different Results When Used In A Stored Procedure.



I have a script with a number of different Left Joins. When I run it in Query Analyzer the Left Join works as a normal join and suppresses some rows. However when the same code is used in a stored procedure the correct results are produced when the stored procedure is executed.
Can anyone tell me what is causing this?

Visual Studio And Stored Procedures With Uniqueidentifier Not Returning Results

I have a stored procedure which simply does a SELECT on a table.  This table has as a column a uniqueidentifier, which is not part of the PK.  If I execute this procedure with the SQL Server tools, it works fine and returns the expected results. If I execute this SP with Visual Studio, or ASP.NET, no results are returned and the following comes back:Running [dbo].[spServiceDetail_Get] ( @ServiceDetailID = <DEFAULT>, @VictimWitnessID = <DEFAULT>).ServiceDetailID VictimWitnessID                                                                                                                                                                                                                       --------------- -------------------------------------- No rows affected.(1 row(s) returned)@RETURN_VALUE = 0Finished running [dbo].[spServiceDetail_Get].  Any ideas what is going wrong?  This seems to be a common problem for many of our tables with a uniqueidentifier in them, and is specifically with VS 2005 and ASP.NET ObjectDataSources.

Returning Closest Results When Search Term Doesn't Exist

I'd like to get some ideas for the following:
I am writing a quick mini-application that searches for records in a database, which is easy enough.  However, if the search term comes up empty, I need to return 10 records before the positon the search term would be in if it existed, and 10 records after.  (Obviously the results are ordered on the search term column)
So for example, if I am searching on "Microsoft", and it doesn't exist in my table, I need to return the 10 records that come before Microsoft alphabetically, and then the 10 that come after it.
I have a SP that does this, but it is pretty messy and I'd like to see if anyone else had some ideas that might be better.
Thanks!

Full-text Index Search Not Returning Expected Results

Hello,

My full-text search isn't working at all! I have a temporary table with full-text indexing enabled where files are scanned for social security numbers. If it has one, the user will see a message that it believes it's found a SSN and won't upload it. There is only ever one row in this table, as we overwrite the contents upon each upload.

I'm testing this search, and it doesn't work. The table has the following columns:
attachemtId (int) - primary key
fileContent (image) - contents of the file
fileExtension (varchar) - extension of the file (this is always either ".pdf" or ".doc")


I created a .doc file that simply says "ssn", and then run the following query:

SELECT * FROM TempAttachment
WHERE CONTAINS(fileContent,'ssn')


and nothing is returned! I tried the same thing with a .pdf file, and same results.

I'm not sure if this is related, but earlier I had this issue where I had to reset permissions for the directory. I've tried removing the full-text index and adding it again, but that didn't do anything. I also checked error logs on the server, and there were no messages. Any help would be appreciated! Thank you!
