Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
I have the following code in my page: <asp:SqlDataSource ID="SqlHolidayDateRange" runat="server" ConnectionString="(OurConnectionString)" SelectCommand="CountHolidays" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:ControlParameter ControlID="WeekEndingDatePicker" Name="EndDate" PropertyName="SelectedDate" /> <asp:Parameter Direction="ReturnValue" Name="RowCount" Type="Int32" /> </SelectParameters> </asp:SqlDataSource> I need to place RowCount, the returned integer value from the stored procedure CountHolidays into a field on the web page. How in the world do I access that data? Everything I've been able to find works if I'm defining my own command object and writing this thing from scratch. What I - and you - have to work with is what's above.

I have a charting control that is fed from an SqlDataSource. How do I set the SqlDataSource to only return the top N records where N is set by a web form control?The user should have the option to chart the top 3, 5, or 10 items.Is the best approach to switch to an ObjectDataSource?
hi,I have a page Price List with GridView to display only two columns of a table (Product name & price). Page size=20. I use SqlDataSource for it. <asp:SqlDataSource ID="SqlDataSource1" runat="server" DataSourceMode="DataSet"In my case the SqlDataSource control return data as a DataSet object. So the DataSet object contains all the data in server memory. I need to create Print Preview page with other columns (Product name & price & Vendor and Date Issue) without paging.I'm going to save dataSet in Session and in Print Preview page use it as datasource (without having to run another query).But I have no idea how to save this DataSet in Session. I don't know the DataSet Name. Any ideas? Thanks.
I have a sproce that accepts null for one of its parameters I can execute the sproce and enter null and it works fine, it returns all rows. When I try doing this with my GridView and the SQLDataSource it does not work. I need some help in understanding how the SQLDatasource wants a null. Here is what the parameter row of the SQLDataSource looks like. <asp:ControlParameter ControlID="EnteredByText" DefaultValue="Null" Name="EnteredBy" PropertyName="Text" Type="String" ConvertEmptyStringToNull="true" /> In my sproce I have setup the parameter as follows; @EnteredBy Nvarchar(50)=Null In my WHERE Clause I have: WHERE (tblClient.EnteredBy = @EnteredBy OR @EnteredBy IS NULL)
I thought I would impliment a new feature of my web page using stored procedures and the SqlDataSource object, for practice or whatever, since I don't normally use that stuff. This is the stored procedure:set ANSI_NULLS ON set QUOTED_IDENTIFIER ON go
ALTER PROCEDURE [dbo].[AppcheckContest] -- Add the parameters for the stored procedure here
@BeginDate datetime = '1/1/2006', @EndDate datetime = '12/31/2006', @SectionID int = 10, @WinnerID int = 0 OUTPUT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
SELECT top 1 @WinnerID = P.UserID FROM cs_Posts P WHERE P.PostDate BETWEEN @BeginDate AND @EndDate AND P.SectionID = @SectionID AND P.UserID <> 2100 -- I don't want to win my own contest...
AND SettingsID = 1000 -- This number could be different if i had more than one CS installed?
AND IsApproved = 1 ORDER BY NEWID() -- yes this is slow, but it works...
RETURN @WinnerID END It's really simple - just needs to return the one randomly chosen integer userID. I've tested it in query designer or whatever it's called in Management Studio and it works fine there at least. Thinking I was done the hard part, I created a new web form in visual studio, dropped a SqlDataSource on it, and used the 'configure data source' wizard from the smart tag to do all the work for me. I didn't have any trouble using the wizard to select my stored procedure, and i'm using the sa connection string to simplify my debugging. I tried using the FormParameter / FormField way of getting the output and setting the input parameters. I can't seem to get it working though. There's no errors or anything, just the output isn't coming through. Here's the code from the aspx codebehind file:Partial Class Contest Inherits System.Web.UI.Page
Protected Sub btnSelectWinner_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSelectWinner.Click Dim stuff As New System.Web.UI.DataSourceSelectArguments SqlDataSource1.Select(stuff) SqlDataSource1.DataBind() lblWinnerID.Text = SqlDataSource1.SelectParameters("WinnerID").ToString End Sub End Class As you can see, I wasn't sure if you're supposed to call databind() or select() to actually get the stored procedure to execute, so I tried both. I was hoping the last line of code there would set the label to the value contained in the @WinnerID parameter, but instead it sets it to "WinnerID". Here's the code from the .aspx file. Most of this was generated by the Wizard, but I messed around with it a bit. <%@ Page Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="Contest.aspx.vb" Inherits="Contest" title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="CPHMain" Runat="Server"> <asp:Button ID="btnSelectWinner" runat="server" Text="Find Winner" /> <asp:Calendar ID="Calendar_From" runat="server"></asp:Calendar> <asp:Calendar ID="Calendar_To" runat="server"></asp:Calendar> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:appcheck-csConnectionString-sa %>" SelectCommand="AppcheckContest" SelectCommandType="StoredProcedure" CancelSelectOnNullParameter="False"> <SelectParameters> <asp:FormParameter FormField="Calendar_From" Name="BeginDate" Type="DateTime" /> <asp:FormParameter FormField="Calendar_To" Name="EndDate" Type="DateTime" /> <asp:Parameter DefaultValue="10" Name="SectionID" Type="Int32" /> <asp:formParameter FormField="lblWinnerID" defaultvalue="666" Direction="InputOutput" Name="WinnerID" Type="Int32" /> </SelectParameters> </asp:SqlDataSource>

I am using a SQLDataSource with Stored Procedures. The Select, Insert and Update all work well. However I cannot get the delete to work. My stored procedures are tested and verified and the parameter names are the same as the source columns. When I try to run the delete an error that the stored procedure expects the parameter @locationStationId, however this value passes properly for the Update command?!? I tried to change the parameter to original_locationStationID to pass the original value, however this result in Null being passed for the parameter. I cannot understand why this works for Update and passes the location ID, but will not work for DELETE. Can anyone shed any light onto the matter?

i have query which does the following select x from y where t = "House"x is an integer. If no record is found, how do i get it to return 0 rather than null?
Hi I have an sql statement that when i put through the query builder and specify NULL it returns all the rows. if i put 0 it returns nothing.how can i change the "IS Null" part of the statement to work with 0. so when i specify 0 for all values it returns all the rows.so i want 0 to work like NULL does 1 SELECT LocationID, TypeID, Title, Description, PropertyID, Price, 2 (SELECT Location 3 FROM Location_Table 4 WHERE (Property_Table.LocationID = LocationID)) AS Location, 5 (SELECT TypeOfProperty 6 FROM Type_Table 7 WHERE (Property_Table.LocationID = TypeID)) AS TypeOfProperty 8 FROM Property_Table 9 WHERE (@MinPrice IS NULL) AND (@MaxPrice IS NULL) AND (@TypeID IS NULL OR 10 TypeID = @TypeID) AND (@LocationID IS NULL OR 11 LocationID = @LocationID) OR 12 (@MinPrice IS NULL) AND (@TypeID IS NULL OR 13 TypeID = @TypeID) AND (@LocationID IS NULL OR 14 LocationID = @LocationID) AND (Price <= @MaxPrice) OR 15 (@MaxPrice IS NULL) AND (@TypeID IS NULL OR 16 TypeID = @TypeID) AND (@LocationID IS NULL OR
I am working on a web application for a company that uses an existing company database. I just found out before the long weekend that a couple hundred of the items in the table aren't completely related.
I am mostly using 2 tables for the project: ItemVersion, ItemVersionRev
ItemVersion has fields: ItemVersion, ItemNumber, RecordID ItemVersionRev has fields: RecordID, RevNumber
All of the items in the database have ItemNumbers (obviously) and most have revision numbers (RevNumber). One of the functions that I created for my application finds the MaxOfRevNumber. I ran a query on the database and saw that dreaded error screen that read "There is no row at position 0"
The query that I have now simply returns MaxOfRevNumber. Is there a way to program a query to check and see if an ItemNumber has a Revision and depending on the result, return a certain value. For example, if there is not a corresponding RevNumber, then return 0 as the RevNumber?
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
I'm developing a web app using VS2005. I have a webpage with panel containing a gridview populated by a SQLdatasource. The SQLdatasource in turn is populated by a stored procedure that can take up to 5 parameters. The user types in up to 5 separate words (searchterms) in a text box which are then parsed and passed to the stored proc in the datasource which performs a fulltext search. The gridview then becomes visible. My problem is that unless the user types in 5 searchterms (no less), the gridview returns zero rows. 5 searchterms returns the proper results. Somehow, I need to be able to pass in null or empty values for unneeded parameters. I've tested the stored procedure in Query Analyzer and from within the SQLdatasource configuration (using Test Query) using 0 up to 5 parameters and it works fine, so that's not my problem. Here's the code that runs after the user types in their search term(s) and presses a button:Public Sub FTSearch_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Handles btnFullText.Command Dim x As Integer pnlFullText.Visible = Falsefiltertext = Replace(txtSearchTxt.Text, "'", "''") If Not filtertext Is Nothing Then filtertext = filtertext.Trim Else Return End IfDim arrayString() As String = filtertext.Split(" ") Dim length As Integer = arrayString.LengthFor x = 0 To (length - 1) If Not arrayString(x) Is Nothing ThenSelect Case x Case 0 : lblFTParm1.Text = arrayString(0)Case 1 : lblFTParm2.Text = arrayString(1) Case 2 : lblFTParm3.Text = arrayString(2)Case 3 : lblFTParm4.Text = arrayString(3) Case 4 : lblFTParm5.Text = arrayString(4) End Select End If Next pnlFullText.Visible = "True" End Sub Any ideas? Thanks in advance.
I am attempting to create search parameters for a gridview control and I am experiencing a small issue. When I get to a date parameter I am unable to display null values. I setup a sqldatasource and created the parameters below to handle the selections for minimum date required and the maximum date required for the date columns in the database. The problem is I do not know how to display null dates. Is there a way to incorporate something into the search page to show null dataes?

The problem I'm having is described below all this code.---------------------------------------------------------My content page has a SqlDataSource: <asp:SqlDataSource ID="sqlGetUserInfo" runat="server" ConnectionString="<%$ ConnectionStrings:RemoteNotes_DataConnectionString %>" SelectCommand="SELECT [UserFirstName], [UserLastName] FROM [Users] WHERE ([UserGUID] = @UserGUID)" onselecting="sqlGetUserInfo_Selecting"> <SelectParameters> <asp:Parameter Name="UserGUID" Type="String" /> </SelectParameters> </asp:SqlDataSource> -----------------------------------------------------Inside my OnSelecting event, I have: protected void sqlGetUserInfo_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { sqlGetUserInfo.SelectParameters["UserGUID"].DefaultValue = Membership.GetUser().ProviderUserKey.ToString(); } ---------------------------------------------------------------------And, inside my Page_Load, the relevant code is: //String strUserFirstName = ((DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty)).Table.Rows[0]["UserFirstName"].ToString(); DataView dvUserDetails = (DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty); if ((dvUserDetails != null) && (dvUserDetails.Count > 0)) { DataRow drUserInfo = dvUserDetails.Table.Rows[0]; lblHelloMessage.Text = "Hello, " + drUserInfo["UserFirstName"].ToString() + ((drUserInfo["UserLastName"].ToString() == "") ? "" : " " + drUserInfo["UserLastName"].ToString()); } ---------------------Now, here's the problem. My "if" statement is never executing because "dvUserDetails" is null. However, when I break the execution and put awatch on the actual Select() statement, it shows a DataView with the correct return rows! You can see the commented line where I tried tobypass the DataView thing (just as a test), but I get an object reference is null error.The weird thing is that it was working fine one minute, then started getting "funky" (working, then not, then working, then not), and now it just doesn't work at all. All thiswithout me changing one bit of my code because I was checking out some UI flow and stopping and restarting the application. I've tracked downthe temporary files directory the localhost web server runs from, deleted all those files, and cleaned my solution. I've even triedrebooting, and nothing seems to make it work again.My relevant specs are VS2008 9.0.21022.8 RTM on Vista Enterprise x64.
Hello all I am trying to run a sql statement, (without having to run stored procedures), that will lookup a value stored in a Record.field., otherwise ignore the value if it is blank. I have a field tied to a Microsoft Access form - ItemLocation. If the user selects a unique ItemLocation the report will attempt to locate all values within that ItemLocation. If the user decides to leave the field blank, I would like for it to return all values for every ItemLocation. If anyone can help, I would really appreciate it. I will attach code. My problem is the last line of this SQL statement. If F.ITemLocation is null, I get no data. I would like for it to return everything. Thank you.

I have this program that I want to invoke from SQLServer funny thing is I can invoke this from command line but could not get it to work via 'xp_cmdshell' on this particular server. When I invoke run the following from SQLServer Query Analyser I always get 'NULL' returned. I tried just running EXEC master..xp_cmdshell 'dir ' and it worked, so I am certain it is not a SQL rights problem.
FYI, I executed the same code on another machine and it worked. I just cannot figure out why it is not working on this one server? Can anyone help? thanks
I have this table 'Request' in which there's 2 fields 'RequestName' and 'DateSubmitted'. The datatype for 'DateSubmitted' is datetimn.
I have to write a query to extract all the 'RequestName' that falls under each month based on the 'DateSubmitted'.
For example, the table 'Request' has 12 rows, each row ('DateSubmitted') with the month of the year. Like row1 = January, row2 = February etc.
For each month, I have to extract all the 'RequestName' for that month based on 'DateSubmitted' field. My query is like this:
select RequestName, datename(month, DateSubmitted)as month from Request where datename(month, DateSubmitted) = 'March'.
By right it should return just one row right?
Instead, it returned me all 12 rows, only one row with value 'March' and the other 11 rows with value 'NULL'. Even if the other 11 rows have value of other months, when i run the above query, it will return me null.
I am trying to return all the names of employees and their managers
this query returns all the employees except for 1
SELECT E.FNAME,E.LNAME,M.FNAME,M.LNAME FROM EMPLOYEE E,EMPLOYEE M WHERE E.SUPERSSN=M.SSN
the one that isn't returned has a null SUPERSSN, but when I add in:
OR E.SUPERSSN IS NULL
it returns a row with the name of the employee whose SUPERSSN is null 8 times (where each time the M.FNAME,M.LNAME are other employee names)
How do I ammend the first query to return each employee and their respective manager once, the employee without a manager having null values for the manager name columns?

SQL Server 2000 SP3.Is it possible for the @@ROWCOUNT function to return NULL after astatement? I am troubleshooting a relatively large stored procedure withmultiple SELECT statements and a couple of INSERTs into table variables.Immediately after each statement I save the value returned by @@ROWCOUNT toa local variable. That information eventually is passed back to the clientvia one output parameter, for all statements in the procedure.Occasionally, the value returned via that parameter is NULL. This cannot bereproduced by re-running the SP with the same input parameters.Before doing any further troubleshooting, I would like to rule out thepossibility that @@ROWCOUNT can actually return a NULL under somecircumstances. From searching the archives, it appears that in SQL Server7.0 this could happen in the context of a DML query on a table withtriggers. This is not the case here - the only DML queries are INSERTs intotable variables, all other queries in the SP are SELECTs.Any related information would be appreciated.--remove a 9 to reply by email

Hi,I have an updatable DataGrid linked to a SQLDataSource in a web site developed using VS2005. Update works fine unless a value in the existing row is Null. Only one column in the database allows nulls.Putting a debug stop in the SqlDataSource1_Updating event, I checked the parameter value in the Immediate window and got the following result:?e.Command.Parameters(16){System.Data.SqlClient.SqlParameter}System.Data.SqlClient.SqlParameter: {System.Data.SqlClient.SqlParameter}DbType: Int32 {11}Direction: Input {1}IsNullable: FalseParameterName: "@original_FiresolveJobNo"Size: 0SourceColumn: ""SourceColumnNullMapping: FalseSourceVersion: Current {512}Value: NothingIs there a property I can set to generate a suitable Null check clause for the Update statement?Many Thanks,Keith.

I even did a stored procedure that just: ALTER PROCEDURE [dbo].[sp_nDeletebyId] @nReturnCode bigint output, @nReturnId bigint output AS SET @nReturnCode = 0 SET @nReturnId = 0 And STILL got nothing but the NULLS... the insert & update stuff works fine, with identical code... it's just the DELETED event that I can't seem to knock. Has anyone seen this before? The above sample stored proc did return 0 when executed one the server... and, BTW, the row is deleted!
