How To Ignor Filtering Criteria If There Is A Null Value For Parameter
May 15, 2008
I have gridview and i want to ignor that filtering if that parameter is empty how do i write that query.
my query is
select * from UserMAster where UserId=@USerID and RoleId=@RoleId
if @UserId is blank then i want to select all records without filtering with user Id a
nd if i have passed null or anything as parameter in roleId then alsoi want all the records if it contain value then i want to do filetring is it possible to with query. or else send me some alternative so that i don't need to execute more query.
I am trying to filter data from columns and this is just not working. If I select all the criteria below and try to run it - I do not get any records returned.
WHERE (DropDt >= DATEADD(month, DATEDIFF(month, 0, GETDATE()) - 13, 0)) AND (DropDt <= DATEADD(month, DATEDIFF(month, 0, GETDATE()) - 1, 0)) and Type IN ('Employee', 'Refinance')
I am using BETWEEN '02/01/2007' AND '2/01/2006' in the criteria of a VIEW and have tried <= '02/01/2007' AND >='2/01/2006' but both are not filtering the dates correctly. Is there another way? What am I missing?
1) Cannot have results in which both m.homephone & d.homephone are both null, or both m.workphone & d.workphone are both null in the result set
2) We also do not want to see any combos where one homephone is null and the other has only the char 0....same for workphone...no null & 0 combinations.
e.g.
m.homephone d.homephone
null 0
0 null
The phone fields are varchar
I know this is hidiously wrong but is my first sloppy attempt at best: select m.number, m.homephone as master_homephone, d.homephone as debtor_homephone, m.workphone as master_workphone, d.workphone as debtor_workphone
FROM master m
INNER JOIN debtors d ON d.Number = m.number
where (d.homephone <> m.homephone OR d.workphone <> m.workphone) AND (d.homephone IS NOT NULL AND m.homephone IS NOT NULL) AND (d.workphone IS NOT NULL AND m.workphone IS NOT NULL) AND NOT ((d.homephone IS NULL AND m.homephone = '0') OR (d.homephone = '0' AND m.homephone IS NULL)) AND NOT ((d.workphone IS NULL AND m.workphone = '0') OR (d.workphone = '0' AND m.workphone IS NULL))
I am facing some problems in displaying data in a chart on a report. Let me give you a background on the report
The report has 8 parameters, Industry,CType,PType, S#, ECode, Start Date, End Date and Trend.
The layout of the report has a table and a chart.
Both the table and the chart need to display Normalized Value ( count of ECode / count of PType that are closed in the date range selected) and the Trend ( where the trend can be Weekly, Monthly, Yearly or Quarterly).
Both the chart and the table should display the data for the entire date range i.e if the Trend is Month and the Date Range is Jan 2007 Jan 2008, then the table and the chart should display months from Jan 2007, Feb 2007 .... Jan 2008 irrespective of whether or not there are error codes present for that month.
In order to satisfy the point 4 mentioned above, we have created the main dataset in such a way that it would have one row for each day between Jan 2007 to Jan 2008. Any fields that do not have data corresponding to a date will come up as NULL in the dataset.
Now, we need to display a chart in the report which would be a Trend v/s the Normalized Value chart for each ECode. So, we have put in the Normalized value in the 'Value' field of the chart, Trend group in the 'Category' field of the chart and ECode in the 'Series' group of the chart. The chart displays fine except for one extra series for the NULL values in the Error Code ( the one in green below). Is there any way in which we can do away with this NULL series without changing the dataset? I tried using filters for the 'Series' but it doesn't work ( used filters like <>NULL, <> "" , <>Nothing, cstr(ECode) <> NULL/"" etc ).
I have a dataset where i want to select the records that matches my input values. But i only want to try macthing a field in my dataset aginst the input value, if the dataset value is not NULL.
I always submit all 4 input values.
@Tyreid, @CarId,@RegionId,@CarAgeGroup
So for the first record in the dataset i get a succesfull output if my input values matches RegionId and CarAgeGroup.
I cant figure out how to create the SQl script for this SELECT?
Hi -- I'm starting an ASP.NET 2.0 application which contains a page with a checkbox and gridview control on it. In its default state the gridview displays all the records from a table pulled from a SQL Server database (via a SqlDataSource object). When the user checks the checkbox, I want the gridview to display only the records where one of the columns is not null. But I've been unable to construct the WHERE clause of the SQLDataSource object correctly. I see that I can hard-code the SqlDataSource object so that the column to be filtered is always NULL or always NOT NULL. But I want this filtering to be more dynamic such that the decision to show all or non-null records happens at run-time. Should I be using two SqlDataSource objects -- one for the NOT NULL condition and one for the "all records" condition? Then when the user checks the checkbox, the gridview would be configured to point to the appropriate SqlDataSource object. (???) Seems like a bit of overhead with that approach. I'm hoping there's a more elegant way to get this done. Please let me know if you need more information. Thanks in advance. Bill
DECLARE @ID UNIQUEIDENTIFIER, @SOMEDATE DATE SELECT * FROM myTable WHERE ID = @ID AND DATEFIELD=@SOMEDATE I want to pass values to @ID and @SOMEDATE, such that it meets the WHERE criteria for all values in the respective fields.
What parameter value should I pass such that all values are selected? In the actual SP, I have uniqueidentifier, varchar and date parameters.
I have built a report using a Cube (and not a relational database).
I have a date as a parameter and I would like to filter its content: the parameter goes from 1900 to 2090 and I would like the user to see only from 2006 to 2090.
Can you help me by giving me tricks to do it ? There may have several ways of doing it but I can't find them.
Hello, I have a report in which I would like to give the user the ability to select how a parameter is filetered. Option 1 would be to filter by a range of value ie: WHERE member.age BETWEEN (@Start) AND (@End) -say everyone between the ages of 50 through 80 Option 2 would be to filter by specific but multiple values ie: WHERE member.age IN (@Age) -say anyone who is 25, 50 and 75. How can this be done? Thanks
<br><br>I obtain table names from a database and pass them to a dropdownlist. Based on user selection, I want to pass each table name to a query.Here is an extract from my code: <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="select * from @dDTable"> <SelectParameters> <asp:ControlParameter ControlID="DropDownList1" Name="dDTable" PropertyName="SelectedValue" DefaultValue="product" Direction="InputOutput" Size="15" Type="String" /> </SelectParameters> </asp:SqlDataSource>I keep getting this error: Must declare the table variable "@dDTable".Please does anyone knows the best way to go about this?
In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
I am using two drop downs, like so: <asp:DropDownList ID="ChurchStateDrop" runat="server" DataSourceID="ChurchStateDropData" DataTextField="State" DataValueField="State" AutoPostBack="True" onselectedindexchanged="ChurchStateDrop_SelectedIndexChanged" AppendDataBoundItems="True"> <asp:ListItem Value="?????" Selected="True" Text="All States" /></asp:DropDownList> <asp:DropDownList ID="ChurchCityDrop" runat="server" DataSourceID="ChurchCityDropData" DataTextField="City" DataValueField="City" AutoPostBack="True" onselectedindexchanged="ChurchCityDrop_SelectedIndexChanged" AppendDataBoundItems="True"> <asp:ListItem Value="?????" Selected="True" Text="All Cities" /></asp:DropDownList> I have ????? in the value fields because I don't know what value needs to be passed to negate filtering (to choose all). The Dropdowns have the following SQLDatasources:<asp:SqlDataSource ID="ChurchStateDropData" runat="server" ConnectionString="<%$ ConnectionStrings:tceDatabaseOnlineSQLConnection %>" SelectCommand="SELECT DISTINCT [State] FROM [ChurchView]" DataSourceMode="DataReader"></asp:SqlDataSource> <asp:SqlDataSource ID="ChurchCityDropData" runat="server" ConnectionString="<%$ ConnectionStrings:tceDatabaseOnlineSQLConnection %>" SelectCommand="SELECT DISTINCT [City] FROM [ChurchView] WHERE ([State] = @State)" DataSourceMode="DataReader"> <SelectParameters> <asp:ControlParameter ControlID="ChurchStateDrop" Name="State" PropertyName="SelectedValue" Type="String" /> </SelectParameters></asp:SqlDataSource> Now, lets say I wanted to pass a value to the WHERE statement in ChurchCityDropData to coincide with 'All States', what would I replace value="??????" with? Now you may think I'm crazy to do such a thing, but this actually has to do with adding a Denomination Dropdown to show Denominations from all states or all cities. I will figure out the best logic for that later, I just want to know the wildcard to pass to the parameter to choose all states (negate filtering).
consider a stored procedure with a parameter @OrderID, i want to perform the following query :select * from Orders where OrderID = @OrderIDi want the condition to be true when parameter @OrderId is null so what is the syntax for that? i think there is an IF CONDITION that can be embedded with where clause.
Hello, I am trying to use a boolean parameter to filter data in a table, but there is something I am missing.
Basically I want something like this: I have a boolean parameter, "EP", and I have a filter set on my table as:
Expression Operator Value =Fields!REFERRAL_SOURCE.Value = IIF (Parameters!EP.Value, "1297", ????)
Using the filter tab, I can't specify an expression for the 'Operator' so I was trying to work it out using either '=' or 'like'. What needs to go into the ???? in order for the referral source to be "not 1297" (i.e. the inverse of the filter)?
Or, am I completely missing an easy way to do this?
Hello All, I was hoping that someone had some wise words of wisdom/experience on this. Any assistance appreciated... feel free to direct me to a more efficient way... but I'd prefer to keep using a stored proc. I'm trying to pass the selected value of a dropdownlist as a stored procedure parameter but keep running into format conversion errors but I am able to test the query successfully in the SQLDatasource. What I would like to do is this: select * from tblPerson where lastnames Like "A%" . Where I pass the criteria after Like. I have the values of the drop down list as "%", "A%", "B%", .... I've been successfully configuring all of the other params, which includes another dropdown list (values bound to a lookup table also)... but am stuck on the above... Thank you for any assistance,
I have a report with a date type parameter. Depending on the value return by this date type parameter the dataset will return either the credit, deposit or process date. How do I go about coding it so that it will dynamically select the right column in my query for my dataset?
I am currently writing a report that will use as one of the filters the date (in this case it is the date of service of a physician office visit).
however the DB developers included the date and the time of the visit in one field so my resulting data set contains 4/13/2007 4:30pm for example, so using an @date parameter as a filter on the data field doesn't work because when you run the report and enter the date in the parameter it doesn't return anything.
I am an SQL Report writer amateur so I am sure there is an easy fix, any and all help will be appreciated.
Im trying to create a drop down parameter whereby if i select a certain field, a different dropdown will be filtered off only the relevant selections, is this possible.
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
I am using SQL 2005. I have a SELECT query in a stored proc with 3 parameters: @subaccount,@numDaysCutoff,@numDaysPcts. The proc needs to be modified to return data when subaccount values are any of these:
FRRIJ FRRIC FRMM ROBECO FRJV MAIL FRUKV FRICE
Currently I use a WHERE condition and am able to get data correctly. However, for a NULL value I should get everything including those not in the above list. Should I use CASE statement instead? How?
@subaccount VARCHAR(8) = NULL , @numDaysCutoff INT = 1 , @numDaysPcts INT = 1

I have a gridview connected to a sqldatasource, and it works pretty good. It gives me the subsets of the information that I need. But, I really want to let them choose all the companies and/or any status. What's the best way to get all the values in the gridview...besides removing the filters :) I thought the company would be easy, I'd just set the selected value to blank "", and then it'd get them all....but that's not working. And, for the boolean, I have no idea to get the value without having a separate query. (tabs_done=@tabsdone) and (company like '%' + @company + '%')1 <asp:DropDownList ID="drpdwnProcessingStatus" runat="server"> 2 <asp:ListItem Value="0">Open</asp:ListItem> 3 <asp:ListItem Value="1">Completed</asp:ListItem> 4 </asp:DropDownList> 5 6 7 <asp:DropDownList ID="drpdwnCompany" runat="server"> 8 <asp:ListItem Value="">All</asp:ListItem> 9 <asp:ListItem Value="cur">Cur District</asp:ListItem> 10 <asp:ListItem Value="jho">Jho District</asp:ListItem> 11 <asp:ListItem Value="sea">Sea District</asp:ListItem> 12 <asp:ListItem Value="san">Net District</asp:ListItem> 13 <asp:ListItem Value="sr">Research District</asp:ListItem> 14 </asp:DropDownList> 15 16 17 <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:HRFormsConnectionString %>" 18 SelectCommand="SELECT DISTINCT [id], [lastname], [company] FROM [hr_term] hr where (tabs_done=@tabsdone) and (company like '%' + @company + '%')"> 19 <SelectParameters> 20 <asp:ControlParameter ControlID="drpdwnProcessingStatus" DefaultValue="0" Name="tabsdone" PropertyName="SelectedValue" /> 21 <asp:ControlParameter ControlID="drpdwnCompany" DefaultValue="" Name="company" PropertyName="SelectedValue" /> 22 </SelectParameters> 23 </asp:SqlDataSource> 24
SELECT * FROM TableA A JOIN TableB B ON A.PrimaryKeyID = B.ForeignKeyID WHERE B.SomeParamColumn = @SomeParam
SELECT * FROM TableA A JOIN TableB B ON A.PrimaryKeyID = B.ForeignKeyID AND B.SomeParamColumn = @SomeParam
Both of these queries return the same result set, but the first query filters the results in the WHERE clause whereas the the second query filters the results in the JOIN criteria. Once upon a time a DBA told me that I should always use the syntax of the first query (WHERE clause). Is there any truth to this, and if so, why?
I have a sql proc. I need to make a parameter optional. I've setup the parameter to use a dataset as its source, and I need NOT to allow the value to be null. I've NOT selected allow nulls check box, But, when the parameter is null (‘’), still data comes back in a table as empty or if it is date will default to 1/1/1900. How do I send a null value to the database through sql proc and raise an error without inserting a null value? I’m hoping to avoid creating a special query just for that purpose.
I Created a Procedure that Generates an ID value based in the current Date (Year/Month) and a value which are stored in a table. This ID value is update in the table, and passed on to an output parameter as folows:
Code Snippet
CREATE PROCEDURE [dbo].[CNSPGetNewGuideID] @SectionID bigint ,@Year bigint ,@Month bigint ,@ID bigint output AS BEGIN
(...)
SELECT @ID = [Year]* 10000000 + [Month] * 100000 + [Number] FROM [dbo].[CNGuideID] WHERE [Year] = @Year AND [Month] = @Month
print 'New ID : ' print @ID END
This is working and the value printed here is the correct one.
but when I execute the procedure inside another one, the variable i pass on as an output parameter remains NULL...
Code Snippet
CREATE PROCEDURE [dbo].[CNSPInsertNewGuide] @SectionID int ,@ClientID int ,@UsuaryID bigint ,@UsuarySectionID int ,@ID int OUTPUT AS BEGIN
DECLARE @Date as datetime DECLARE @Year as int DECLARE @Month as int
SET @Date = GetDate() SET @Year = YEAR(@Date) SET @Month = MONTH(@Date)
I'm passing a list of values to a stored procedure using an XML parameter - using SQL 2005.
The stored procedure is used to search a table for matching values so this list can contain one or many values, or could be NULL to indicate all values should be returned.
Returning one or more than one value works fine in the code sample given below. How can I phrase my query to cope with the scenario of the parameter being NULL to select all values?
I currently have the following code to cope with one or many values being passed:
Code Snippet
SELECT * FROM dbo.MyTable WHERE idField IN (SELECT paramvalues.id.value('.', 'int') FROM @testxml.nodes('/rootnode/idfieldvalue') as paramvalues(id)) where @testxml is the XML parameter passed into the stored procedure.
In the report I created, there is a drop down used as a parameter, i.e. Sector. This drop down gets populated with data. It also has <Select a Value> in there. When no item is selected, i.e. only <Select a Value> is shown in the drop down list, when the view Report button is clicked, the message says: Please select a value for the parameter 'Sector' The view Report used a stored procedure which allows null for this Sector parameter. The SP does work fine in the sql server query analyser because it returns data with and without the sector parameter. Any thoughts please? Thanks
