Dear All
I am trying to populate an OledbDatareader for binding to a ASP datagrid.
For this I use select statement to display combined fields in a datagrid cell.
Eg. Select (Field1+ '<br/>' + Field2 + '<br/>' + Field 3) As Address .. and so on.
But the problem is if any of the three field is null the combined field 'Address' returns as Null.
Please help me to overcome this problem.
I am building a file repository page. For data source I use SQLDataSource and Repeater to display the categories. I am trying to achieve the result of displaying the following data: List of all "Main Categories" and all "Sub Categories" under each main category name. Also, "Total Number of files" and "Category Description" under each "Main Category". Sample:
Human Resources All documents related to new hire process. New Hire Request forms, New Hire forms, Termination Forms Total Files: 25
Programs & Utilities Windows utilities and other tools to keep you safe on the net. Antivirus, Spyware Removal Tools, Other programs Total Files: 37
My SQL2005 DB has 2 tables.
1) FileCategories. Fields(CategoryID, ParentCategoryID, CategoryName, CategoryDescription) 2) Files. (CategoryID, ParentCAtegoryID, FileTitle) My "Main Categories" are the ones that has a NULL in ParentCategoryID field. Because they are the Parents. My each "Sub Category" has it's own ID as well as parentCategoryID. This insures that each Sub Category corresponding to it's parent only. Sample:
Human Resources. CategoryID=4, ParentCategoryID=NULL New Hire Request forms. CategoryID=13, Parent CategoryID=4 New Hire Forms. CategoryID=17, Parent CategoryID=4 Termination Forms. CategoryID=22, Parent CategoryID=4
When I am creating a sql Select statement first I need to choose All "CategoryIDs" where "Parent category" is NULL. Then All "CategoryIDs" where "Parent categories" are not NULL and corresponding to Main Categories. Is it something accomplishable with SQLdataSource or I have to use ObjectDataSource or something else. I'll be on the site all day today (10/29/07) and tomorrow (10/30/07) checking for replies. Thanks in advance and let me know if you have any questions.
I am trying to figure out a way to toggle the visibility of attribute data based on a parameter. Specifically, I have a report that has many columns that an end-user may not want to see, depending on what they are using the report for. I know you can toggle visibilities on individual columns easily enough, however I want the user to be able to select which fields (at the attribute level) they want visible on the report up in the parameters, via a multi-value prompt.
I have built an Advanced Search page which allows users to select which columns to return (via checkbox) and to enter search criteria for any of the selected columns (into textboxes). I build the SQL statement from the properties of the controls. Works great. My problem is getting my gridview control to play nicely. At first I used a SqlDataReader and bound the gridview to it, thus giving me the ability to run new SQL statements through it (with different columns each time). Worked nicely. But, per Microsoft, sorting can only be done if the gridview is bound to a datasource control like the SqlDataSource. So I wrote the code to handle sorting. No big deal; worked nicely. But I could not adjust the column widths programmatically unless bound to a datasource control like the SqlDataSource. And could not figure out a work around. So, I decided to use the SqlDataSource. Works great. Except, I cannot figure out how to run a new SELECT statement through the SQLDataSource and have the gridview respond accordingly. If I try to return anything other than the exact same columns defined declaratively in the html, it pukes. But I need to be able to return a new selection of columns each time. For example, first time through the user selects columns 1,2,3,4 – the gridview should show those 4 columns. The second time the user selects columns 2,5,7 – the gridview should those 3 columns (and ONLY those 3 columns). Plus support selection and sorting. I am desperate on this. I've burned 2.5 days researching and testing. Does anyone have any suggestions? Thanks, Brad
Select statement. In my database i am using the employee table. I need my first column to display your full name is 99 characters. so like if the employee is john smith it would display Your Full Name Is 9 characters (including the space).
The data I have has a 1 in for each Yes answer and a 2 for each no answer. I just want the select statement to show the word yes when there's a 1 and the word no when there's a 2. I don't need to update or change the database. Could anyone lead me in the right direction here? Thanks
Hi,Is there a way to exclude fields in a query other than just includingthe ones you want. If there are 20 fields and you want to see all but3, it would be a lot easier to exclude the 3.Thanks
I thought this was working, but apparently it was not. I was wondering how I would create a SELECT Statement for values that are blank (Equal to ""). I really could have swore that this was working, but I guess it wasn't.
// create an open the connection OleDbConnection conn = new OleDbConnection(conString); OleDbCommand command = new OleDbCommand(); command = conn.CreateCommand();
// create the DataSet DataSet ds = new DataSet();
// run the query command.CommandText = "SELECT ID AS [#], Company AS [Company], FName AS [First Name], LName AS [Last Name], Type AS [Type] FROM Table1 WHERE Tags = @P0;"; OleDbDataAdapter adapter = new OleDbDataAdapter(); adapter = new OleDbDataAdapter(command); command.Parameters.Add("@P0", OleDbType.VarChar).Value = ""; adapter.Fill(ds);
// close the connection conn.Close();
bindingSource1.DataSource = ds.Tables[0];
DataGridView.DataSource = bindingSource1;
// set the size of the dataGridView Columns this.DataGridView.Columns[0].Visible = false; this.DataGridView.Columns[1].Width = 234; this.DataGridView.Columns[2].Width = 50; this.DataGridView.Columns[3].Width = 50; this.DataGridView.Columns[4].Width = 75;
//Sort on the Title Column DataGridViewColumn sortColumn = DataGridView.Columns[1]; ListSortDirection direction; direction = ListSortDirection.Ascending; DataGridView.Sort(sortColumn, direction);
//Set the Selected Property of the First Row to False DataGridView.Rows[0].Selected = false; } catch { }
Is it possible to combine fields and text in a select statement? In a dropDownList I want to show a combination of two different fields, and have the value of the selected item come from a third field. So, I thought I could maybe do something like this: SELECT DISTINCT GRP AS GroupName, "Year: " + YEAR + "Grade: " + GRD AS ShowMe FROM GE_Data WHERE (DIST = @DIST)
I hoped that would take the values in YEAR and GRD and concatenate them with the other text. Then my dropDownList could show the ShowMe value and have the GroupName as the value it passes on. However, when I test this in the VS Query Builder, it says that Year and Grade are unknown column names and changes the double-quotes to square brackets. If this is possible, or there's a better way to do it, I'd love some more info. Thanks! -Mathminded
I've been busy all night searching and reading trying to figure out how I can do the following.
I have a table that tracks user IDs in multiple fields. When I select records from this table I need a way to resolve those ID fields back into user names by referencing the users table. SQL statement thus far...
SELECT A.Username as NameA, B.Username As NameB, FROM theTable, Users As A, Users As B WHERE theTable.UserIDA ???
How do I resolve theTable.UserIDA and theTable.UserIDB back to Users.Username so that the records returned fill the fields NameA and NameB?
Hi to allI wish to be able to have a standard select statement which hasadditional fields added to it at run-time based on suppliedparameter(s).iedeclare @theTest1 nvarchar(10)set @theTest1='TRUE'declare @theTest2 nvarchar(10)set @theTest2='TRUE'selectp_full_nameif @theTest1='TRUE'BEGINother field1,ENDif @theTest2='TRUE'BEGINother field2ENDfrom dbo.tbl_GIS_personwhere record_id < 20I do not wish to use an IF statement to test the parameter for acondition and then repeat the entire select statement particularly asit is a UNIONed query for three different statementiedeclare @theTest1 nvarchar(10)set @theTest1='TRUE'declare @theTest2 nvarchar(10)set @theTest2='TRUE'if @theTest1='TRUE' AND @theTest2='TRUE'BEGINselectp_full_name,other field1,other field2from dbo.tbl_GIS_personwhere record_id < 20ENDif @theTest1='TRUE' AND @theTest2='FALSE'BEGINselectp_full_name,other field1from dbo.tbl_GIS_personwhere record_id < 20END......if @theTest<>'TRUE'BEGINselectp_full_namefrom dbo.tbl_GIS_personwhere record_id < 20ENDMake sense? So the select is standard in the most part but with smallvariations depending on the user's choice. I want to avoid risk ofbreakage by having only one spot that the FROM, JOIN and WHEREstatements need to be defined.The query will end up being used in an XML template query.Any help would be much appreciatedRegardsGIS Analyst

I'm trying to Display 2 fields using the SalesOrderDetail table.
CarrierTrackingNumber
Count the number of CarrierTrackingNumber and give alias name of “Count CarrierTrackingNumber.”
I only want to return records where the CarrierTrackingNumber has count = or greater than 2.
Below is the SQL I developed, but I'm getting this error when I try to execute: Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the nvarchar value '4911-403C-98' to data type int.

I want to select all the fields from just one table This is what i have and i am having trouble selecting all the fields select * from ace_users where chdata EXISTS (select chdata, count(chserialnum) from ace_users group by chdata having count(chserialnum)> 1)
Now I need to display the second field which is a #-separated field as individual fields alongwith tghe other fields that are shown on execution of the query. Can this be done? Please guide me on this...
I have a requirement to display the elapsed time between two datetime fields. What i have been able to do is datediff the dates and get the elapsed time in minutes and then i am trying to format it as HH:MM.
For example, an activity started on Nov 1 2007 08:00 and finished Nov 1 23:59, the elapsed time should be displayed as 15:59.
The other example is if the activity spans over a couple of days, it should be say 49:03.
I put the following code in the format of the textbox, but it only seems to work when the length of the minutes is greater than 1.
I have a report parameter named "Schools" which display a list of schools. For example, Alo elementary school, Balo middle school and Calo high school.
When "Alo elementary" is selected the report only display students from that school along with other assessments data fields. same goes for other schools too. But I want to display different data fields for "Calo high school" when it is selected. It is not currently possilbe becasue I am using the same template for all types of schools. There some fields only should be displayed for "Calo high school" but not for any other type of schools.
I can accomplish this by creating two separate report, one for "Calo high school" and the other for other schools. But I want to accomplish this just by creating one report. So when "Alo elementary school" is selected it displays report with certain fields and when "Calo high school" is selected then it displays same fields as "Alo elementary school" but as well as some other fields too in the report. Is this possible? Need help.
Hi, Im trying to pull data from 2 fields in the same table into a SqlDataSource that feeds into a GridView, and display them as 1 field in GridView? I have a database table that has entries of users and their friends. so this tblFriendUser has a column called UserName and another column called FriendUserName. I am trying to get a list of friends for that particular user. Note that if User1 initiated the friend request, he will be listed as UserName and his friend as FriendUserName, but if his friend initiated the friend request, it will be vice versa: him being the FriendUserName and his friend the UserName. So I want the following 2 queries run and merged into one query in order to return 2 columns only: UserFriendID & UserName, is that possible? Is my design bad? Any suggestions/advice would help! Thanks a lot!
SELECT UserFriendID, UserName FROM tblUserFriends WHERE (UserName = @UserName);
SELECT UserFriendID, FriendUserName AS UserName FROM tblUserFriends WHERE (FriendUserName= @UserName);
I have a page that is displaying different movie covers. They each have their respective genres stored in several keys (genre0, genre1, genre2). Now I can search within the movies by changing the url variable movies.aspx?genre=action but if I simply go to movies.aspx, I'm wanting all genres to appear. But for me, the page is blank if I don't specify the genre. So I've had to start filling in the genre All for all movies so I can go to movies.aspx?genre=all but I know this can't be necessary. Is it my SQL statement for the datasource causing the problem? Code is in VB. <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=xxx;Initial Catalog=xxx;User ID=xxx;Password=xxx" ProviderName="System.Data.SqlClient" SelectCommand="SELECT * FROM [Movies] WHERE [genre0] = @strGenre OR [genre1] = @strGenre OR [genre2] = @strGenre"> <SelectParameters> <asp:QueryStringParameter Name="strGenre" QueryStringField="genre" /> </SelectParameters> </asp:SqlDataSource>
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
INNER JOIN qryPRDGroupDets on Prdct.ProdGrp=qryPRDGroupDets.PGCode
where supersed ='' And OrigPr Not Like '9%' And OrigPr Not Like '%MDM%' And LISTPR1>'0' And STANCOST>'0'
Which works fine, but what I need to do is reference the "OrigPr" field and mark it as "valid" or "Invalid", the "OrigPr" the field contains alpha numeric data e.g. A000, A001, A002 - ZZ99 and so on, amongst all of the potential different types of codes we have codes that end in treble Zero (0) e.g. A000 which are valid, but if they end in double 00 e.g. AA00 then this is invalid, the problem I have is I can't just add
Code: 'Marker'= Case When Right(OrigPr, 2) = '00' Then 'Invalid' ELSE 'Valid' End
For it will mark the A000 as invalid, is there a way of getting around this...

The following is a simplified version of my SQL statement. I am attempting to do a simple count(*) with two groupings and a where clause. This is Select command for a GridView. However, I am unable to display zeros. The rows are completely missing and I would greatly appreciate someone's help. I have already tried Group By All, but that, unfortunately, does not work. Here is my SQL statement:
"SELECT [GENDER], [RACE], COUNT(*) FROM [TABLE] WHERE ([COLUMNNAME] ='SOMETHING') GROUP BY [GENDER], [RACE]"
