Help Getting My If Statement To Reconize That My Stored Procedure Returns DBNULL
Mar 31, 2008
Ok well i have a stored procedure that returns an integer between 1 and 5. My problem now is i want to check to see if the table will return NULL and if so i don't want to assign the value to my variable otherwise it'll trow an error. My code is listed below but i keep getting the error "Conversion from type 'DBNull' to type 'Integer' is not valid." i've also tried
If getoptionpicked.Parameters("@optionpicked").Value = Nothing Then
If getoptionpicked.Parameters("@optionpicked").Value Is system.dbnull Then
below is the rest of the code
If getoptionpicked.Parameters("@optionpicked").Value Is Nothing Then
Else
optionpicked = getoptionpicked.Parameters("@optionpicked").Value
If optionpicked = 1 Then
option1.Checked = True
ElseIf optionpicked = 2 Then
option2.Checked = True
ElseIf optionpicked = 3 Then
option3.Checked = True
ElseIf optionpicked = 4 Then
option4.Checked = True
ElseIf optionpicked = 5 Then
option5.Checked = True
Else
End If
End If

Hi,I have a stored procedure which returns an integer indicating whether the operation has succeeded or failed. It does this by calling set @returnvalue = (0 or 1) then select @returnvalue as returnvalue in the stored procedure code. When I run the stored procedure, inputting a set of parameters as it expects, it does what it's supposed to do and outputs a table with a single row and a single column, called returnvalue, which has a value of either 1 or 0. When I run the stored procedure through a function in asp, using the exact same set of parameters, output the results as a data set and try and convert the return as an integer I get the following error: "Object Cannot be cast from DBNull from other types"The conversion code is ..return Convert.ToInt32(ds.Tables[0].Rows[0]["returnvalue"]);And if I change "returnvalue" to anything else (like "wibble" for example) then I get a different error telling me it can't find the column named "wibble". So the dataset definitely contains a table with a column in it called returnvalue, as you expect. But it's value is, apparently, DBNull instead of an integer.How come this works when called directly through SQL and fails when called through ASP? Can anyone help? This is really doing my head in!Cheers,Matt

I have quite a few tables which allow NULL values. I have to struggle a lot with DBnull Exceptions :|example: col1,col2,... are all columns of type Integer and possibly NULL. var query = from person in table select new { person.col1, test = (int?) person.col2, person.col3, person.col4, ...}; As soon as my result encounters a DBNull value.. the whole query fails. This is really bad.How would I return the valid values.. and set the keys where there is no value to a null type? (e.g. int -> 0)I tried using "(int?)" but I'm not *really* sure what it does :-) Anyway.. it has no effect :-)

If I run this statement in Query Analyzer, it properly returns 1for my testing table. But if I put the statement into a storedprocedure, the stored procedure returns NULL. What am I doingwrong? I suspect it may be related to how I defined the parametersfor the stored procedure. Perhaps my definition of TableName andColumnName don't match what COLUMNPROPERTY and OBJECT_ID expect toreceive, but I don't know where to look for the function declarationsfor those. Any pointers would be appreciated.Select statement:SELECT COLUMNPROPERTY(OBJECT_ID('Table1'), 'TestID', 'IsIdentity') ASIsIdentityTable definition:CREATE TABLE [dbo].[Table1] ([TestID] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[Description] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]Stored Procedure definition:CREATE PROCEDURE spTest(@TableName varchar,@ColumnName varchar)AS SELECT COLUMNPROPERTY(OBJECT_ID(@TableName), @ColumnName,'IsIdentity') AS IsIdentity

Hi,I have a stored procedure (the code is below) that I use to retrieveone value from my database. I tested the code in Query Analyzer, and itworks (I get the value I was looking for). However, when I call thesame code from the stored procedure, I get no value. The code that isexecuted is the same and the input parameter is the same. Does anybodyhave an idea?The code:SELECT Top 1CharID,CharName,CategoryName,CharDescription,UserIDFROM [Character]WHERE CharName='Character'-- returns the right valueThe Stored Procedure:CREATE PROCEDURE SpCharacters_SelectOneByUserName@UserName NVarCharASSELECT Top 1CharID,CharName,CategoryName,CharDescription,UserIDFROM CharacterWHERE CharName=@UserNameGO-- returns no value

Hello,I have a stored procedure: -- Get an individual league match by IDALTER PROCEDURE [dbo].[mb_League_GetLeagueMatchByID]( @LeagueMatchID int)ASSET NOCOUNT ONSELECT * FROM mb_LeagueMatch WHERE mb_LeagueMatch.LeagueMatchID = @LeagueMatchIDThe mb_LeagueMatch table has a column named IsActive that is a bit datatype.The value for all rows is set to true (in database explorer in visual studio 2005).When I execute the above stored procedure I always get -1 (I'm guessing that means null) as a result for IsActive if it was true and 0 when false (as expected).However, when I run a query on the database for the same parameter, I get the expected 1 as the value for IsActive.Has anyone seen this before?Thanks,Howard

I have following stored procedure:
-------------
CREATE PROCEDURE dbo.Test
@name as char(36)
as
select a, b
from testtable
where name LIKE @name +'%'
------------
when I run the select statement from query analyzer,
select a, b from testtable where name LIKE 'a%'
it returns records.
But when I call the stored procedure from query analyzer,
exec Test 'a'
it returns no record.
What might be wrong?
Any help is appreciated.

I am new to SQL and SQL Server world. There must be a simple solutionto this, but I'm not seeing it. I am trying to create a crystalreport (v8.5) using a stored procedure from SQL Server (v2000) inorder to report from two databases and to enable parameters.When I create the stored procedure, it joins multiple one-to-manyrelationship tables. This results in repeated/duplicate records. Isthis an issue that should be solved within the stored procedure, or isthis inevitable? If latter, how do you eliminate the duplicates inCrystal Reports?Let's say we have three different tables - Event, Food, Equipment.Each event may have multiple food and multiple equipments; some eventsmay not have food and/or equipments. The stored procedure outcome maylook like this:Event Food Food_Qty EquipmentEquipment_QtyEvent1 Food2 10 Equipment51Event1 Food4 10NULL NULLEvent2 Food4 50 Equipment210Event2 Food4 50 Equipment52Event2 Food1 12 Equipment210Event2 Food1 12 Equipment52As you can see in Event2, for each Food variations, Equipment valuesrepeat. When I am creating a Crystal Reports, I have the duplicationproblem.What I would like to see in the report is either:Event1Food2, 10 Equipment5, 1Food4, 10Event2Food4, 50 Equipment2, 10Food1, 12 Equipment5, 2OR:Event1Food2, 10Food4, 10Equipment5, 1Event2Food4, 50Food1, 12Equipment2, 10Equipment5, 2Attempt1: Using "Eliminate Duplicate Record" option does not work withthe Equipment section since CR does not recognize "Equipment2" in thethird line of the table and "Equipment2" in the fifth line of thetable as duplicates.Event1 Food2, 10 Equipment5, 1Food4, 10Event2 Food4, 50 Equipment2, 10Equipment5, 2Food1, 12 Equipment2, 10(duplication)Equipment5, 2(duplication)Attempt2: I created group for each category (Event, Food, Equipment),put the data in Group Headers and used "Suppress Section" to eliminateif the same equipments are listed more than once within the Foodgroup. This eliminated the duplication, but the items do not aligncorrectly.Event1 Food2, 10 Equipment5, 1Food4, 10Event2 Food4, 50 Equipment2, 10Equipment5, 2Food1, 12 (I want this to appear right below the'Food4, 50' line)I would really appreciate any suggestions! Thank you in advance.

SET CONCAT_NULL_YIELDS_NULL ON
GO
now if i run this stored procedure in Query Analyzer like so...
exec wea_SelectEmployeeListByCourseOrProject 0,0,1,'K_T'
i get 48 records returned.
but if i lift the SQL out of the stored procedure and run it in Query Analyzer like so....
Code Block

)
OR

)
SET CONCAT_NULL_YIELDS_NULL ON
i only get 5 records returned???
so why do i get a difference when its the same SQL??
Username 'K_T' is of role 'MIS_TUTOR' therefore @Role = 'MIS_TUTOR'
any help on unravelling this mystery is appreciated!
Cheers,

I have a stored procedure on a SQL server, which is workign correctly to check some date/time parameters and then insert a row into a log table.
I am calling it from an ASP page. Initially I just called it and didn't worry about the return value. However the Stored procedure now will return a value to determine if it made the change or not and if not why (ie log entry was at incorrect time etc).
I woudl liek to capture this returned value in my code to display a message to the user but am havign problems finding the right way to get the value.
I am calling the SP as follows:
Shared Sub createlogentry(ByVal ID, ByVal tme, ByVal val) Dim result As String Dim cs As String = ConfigurationManager.ConnectionStrings("connecttion1").ToString Using con As New System.Data.SqlClient.SqlConnection(cs) con.Open() Dim cmd As New System.Data.SqlClient.SqlCommand() cmd.Connection = con cmd.CommandType = Data.CommandType.StoredProcedure cmd.CommandText = "CreateLogEntry" cmd.Parameters.Add("@ChID", Data.SqlDbType.Int) cmd.Parameters("@ChID").Value = ID cmd.Parameters.Add("@Value", Data.SqlDbType.Int) cmd.Parameters("@Value").Value = val result = cmd.ExecuteNonQuery().ToString End Using End Sub
I have tried amending the ExecuteNonQuery line to ExecuteReader()
Any help appreciated

Clive

Hi !
I have trying to do an insert with a subroutine that calls a stored procedure, but it doesn’ t run. The page loads properly but nothing is inserted in the table of the database, no errors appears after submit the form.
<asp:Button id="SubmitButton" OnClick="Send_data" Text="Submit" runat="server"/>
Here is the code:
Sub Send_data(Sender As Object, E As EventArgs)
Dim CmdInsert As New SqlCommand("new_user1", strConnection)
CmdInsert.CommandType = CommandType.StoredProcedure
Dim InsertForm As New SqlDataAdapter()
InsertForm.InsertCommand = CmdInsert
CmdInsert.Parameters.Add(New SqlParameter("@RETURN_VALUE", SqlDbType.bigint, 8, "User_id"))
CmdInsert.Parameters("@RETURN_VALUE").Direction = ParameterDirection.ReturnValue
CmdInsert.Parameters.Add(New SqlParameter("@e_mail", SqlDbType.varchar, 50, "e_mail"))
CmdInsert.Parameters("@e_mail").Value = mail.Text()
End Sub
What it lacks?

Guys,
could someone please tell me : am I supposed to use the OLE DB
Command in a dataflow to call a stored procedure to return a value? Or
is it just supposed to be used to call a straightforward insert
statement only?
What I am hoping to do:
I have a table with a few columns and one identity column. In a
dataflow I would like to effect an insert of a record to this table and
retrieve the identity value of the inserted record... and I'd like to
store the returned identity in a user variable.
If I AM supposed to be able to do this... then how on earth do I do it?
I have spent hours fooling around with the OLE DB command trying to call a stored proc and get a return value.
In the Advanced Editor any time I try to add an output column (by
clicking on Add Column) I just get an error dialog that says "the
component does not allow adding columns to this input or output)
So, am getting pretty concussed .. banging my head of the wall like this...
So put me out of my misery someone please.... is the OLE DB Command intended for this or not?
Thanks

I have a Column called SaleID in some tables in a Database.The SaleID column has the int datatype. I need a stored procedure that returns the next value in sequence for the SaleID column.
For Example,
If the last value inserted into the SaleID column was 1022 the stored procedure should return 1023
If the last value inserted into the SaleID column was 1023 the stored procedure should return 1024.
If the last value inserted into the SaleID column was 1024 the stored procedure should return 1025.
Also an exclusive lock should be maintained while the the stored procedure is running.
I am using SQL Server 2005.

I have a Gridview bound to a SQLDataSource that uses a Stored Procedure expecting 1 or 2 parameters. The parameters are bound to textbox controls. The SP looks up a person by name, the textboxes are Last Name, First Name. It will handle last name only (ie. pass @ln ='Jones' and @fn=null and you get all the people with last name=Jones. I tested the SP in Management Studio and it works as expected. When I enter a last name in the Last Name textbox and no First Name I get no results. If I enter a Last Name AND First Name I get results. I don't understand.
Here's the HTML View of the page. The only code is to bind the Gridview when the Search button is pressed.

I'm pretty new to .NET and am looking for advice on how to speed up a simple stored procedure that returns 35,000 plus rows. It's a super simple query that returns a client list. It's just that there is soooooo many rows, it's super slow when the page loads.

I have a stored procedure that works when executed in query analyzer. (It is also way too long to post here) When called from my application ado.net returns the error:
Invalid object name #idTable
If I run the proc in query analyzer using the same parameters (copied from quickwatch while debugging) there is no error.
While very complicated, this procedure runs quickly so timing out is not an issue.
Does anyone know why a proc would run in query analyzer and not in an asp.net/c# application?
Thank you.

I have a stored procedure like "select * from ThisTable"
I'm doing a dataread like:
Dim val as String = dateRead("column_from_ThisTable")
If the value in the column is not null everything works great, but if the value is null, instead of getting a value of "" which I expect, I get the column name??? In this case "column_from_ThisTable"
How do I make sure I get "" returned when the value in the column is db.null?

The Query:
Code:
AS
DECLARE@UPLIDCount int
DECLARE @OldUPLIDCount int
SELECT @UPLIDCount = (SELECT Count(UPLID)/1000 AS adjcount
FROM tblProvLicSpecloc
WHERE DelDate is null
OR DelDate > GETDATE())
IF EXISTS(SELECT var FROM tblDMaxVars WHERE var = 'UPLID Count')
BEGIN
SELECT @OldUPLIDCount = (SELECT var FROM tblDMaxVars WHERE var = 'UPLID Count')
IF @UPLIDCount > @OldUPLIDCount
BEGIN
UPDATE tblDMaxVars
SET value = '' + CAST((@UPLIDCount*1000) AS nvarchar(1000)) + ''
WHERE var = 'UPLID Count'
END
END
ELSE
BEGIN
INSERT INTO tblDMaxVars (var, value, description)
VALUES ('UPLID Count', '' + CAST((@UPLIDCount*1000) AS nvarchar(1000)) + '', 'counts UPLID records and rounds down to the nearest thousand')
END
GO
The table tblDMaxVars only has three columns, none of which are integers, yet I still return this error:
Code:
Syntax error converting the varchar value 'UPLID Count' to a column of data type int.
Please help.

Hi there everyone. I have a stored procedure called “PagingTable� that I use for performing searches and specifying how many results to show per ‘page’ and which page I want to see. This allows me to do my paging on the server-side (the database tier) and only the results that actually get shown on the webpage fly across from my database server to my web server. The code might look something like this:
strSQL = "EXECUTE PagingTable " & _
"@ItemsPerPage = 10, " & _
"@CurrentPage = " & CStr(intCurrentPage) & ", " & _
"@TableName = 'Products', " & _
"@UniqueColumn = 'ItemNumber', " & _
"@Columns = 'ItemNumber, Description, ListPrice, QtyOnHand', " & _
"@WhereClause = '" & strSQLWhere & "'"
The problem is the stored procedure actually returns two result sets. The first result set contains information regarding the total number of results founds, the number of pages and the current page. The second result set contains the data to be shown (the columns specified). In ‘classic’ ASP I did this like this.
'Open the recordset
rsItems.Open strSQL, conn, 0, 1
'Get the values required for drawing the paging table
intCurrentPage = rsItems.Fields("CurrentPage").Value
intTotalPages = rsItems.Fields("TotalPages").Value
intTotalRows = rsItems.Fields("TotalRows").Value
'Advance to the next recordset
Set rsItems = rsItems.NextRecordset
I am trying to do this now in ASP.NET 2.0 using the datasource control and the repeater control. Any idea how I can accomplish two things:
A) Bind the repeater control to the second resultset
B) Build a “pager� of some sort using the values from the first resultset

pst.setString(1, "IN");
//
rs = pst.executeQuery();
rs.last();
System.out.println(" Row Number "+rs.getRow());
rs.beforeFirst();
while(rs.next())
{
System.out.println(" Procedure is "+rs.getString(1));
}
same sp working perfectly with SQL Server 2000
am getting a error message
com.microsoft.sqlserver.jdbc.SQLServer
Exception: A server cursor cannot be opened on the given statement or statements
. Use a default result set or client cursor.
If a SP doesnt have a temp table, then there is no issue, SP executes perfectly, but if a SP has a temp table, this error occurs.
SP :
create proc testProcedure
@countrCode varchar(3)
as
select countryname INTO #TMPCOU from country where countryCode = @countrCode
SELECT COUNTRYNAME FROM #TMPCOU
Its really very urgent. Please help me...!

How do you use an if then statement in a sql stored procedure? I have a table with 3 columns in it. When the tableis updated, I will only need one particular column in the database updated at a time. I will signal which column to update with an integer value(WhichColumn). So I want to key off that value to determine which column is to be updated.
Here is my pseudo code
if(WhichColumn EQUALS 1){ Update InsertEntry SET FirstColumn=Value}else if(WhichColumn EQUALS 2){ Update InsertEntry SET SecondColumn=Value}else if(WhichColumn EQUALS 3){ Update InsertEntry SET ThirdColumn=Value}
Here is a rough start to my stored procedure to incorporate the logic aboveGOCREATE PROCEDURE [dbo].[InsertEntry]( WhichColumn int Value nvarchar(500), )

Hey all, don't know where I am going wrong on this, and maybe it's just that it can't be done. Below is the stored procedure and page code, and after that is the description of the prob*************************
SP_GetDetails
@wherestring varchar(400) ASSelect title_id, title, type, ytd_sales, pub_id from titles where title_id IN (@wherestring)*****************************This is the function that calls SP_GetDetails*****************************Public Function GetDetails(ByVal title As String) As DataViewDim DS As DataSetDim myconnection As SqlConnectionDim mycommand As SqlDataAdaptermyconnection = New SqlConnection(_ConnString)mycommand = New SqlDataAdapter("SP_GetDetails", myconnection)mycommand.SelectCommand.CommandType = CommandType.StoredProceduremycommand.SelectCommand.Parameters.Add(New SqlParameter("@wherestring", SqlDbType.VarChar, 400))mycommand.SelectCommand.Parameters("@wherestring").Value = titleDS = New DataSetTry mycommand.Fill(DS, "Details") Return DS.Tables("Details").DefaultViewCatch ex As Exception Throw exFinally myconnection.Close()End TryEnd Function****************************And this is the Function that Calls GetDetails:****************************Public Sub Get_Info(ByVal Sender As Object, ByVal e As EventArgs)Dim data As New DataLayerDim titles As String = ""Dim item As ObjectDim ltitle As StringDim i As Integer = 0For Each item In ListBox2.Items() If ListBox2.Items(i).Selected Then ltitle = ListBox2.Items(i).Value.ToString If (i > 0) And Not (titles = "") Then titles += ", '" & ltitle & "'" Else titles += "'" & ltitle & "'" End If End If ltitle = "" i += 1NextDataList1.DataSource = data.GetDetails(titles)DataList1.DataBind()End Sub****************************Problem:The DataSet is not getting any values. If I run the procedure in the QA with values that I know work, in the place of @wherestring, it works fine and I get the proper results. However if I try and give it a value (ie: Get_Info() returns "'BU1032', 'BU1111'", which are valid values, it doesn't respond) I have a feeling that its the way that the information @wherestring gets isn't formated right to be able to plug into the SP but I don't know any other way to do it...help is greatly appreciated and if you have any questions I will answer back immediately. thanks a ton. --Shred

Hey everyone!
I have a stored procedure that returns employee id's and how many shifts they have signed up for between 2 dates.
If they have less then 3 entries between the date range specified I would like update their status field to inactive.
So what I'm getting at is how would I go about doing an IF statement that would check through the results of my stored procedure to see who has worked less then 3 shifts and to execute another stored procedure to update their status.

Hello,
I am new to this.
I am creating am trying to create a stored procedure that looks to see what group_id number a user selected and if they select no group_id number than it should return one of a specific set that I specify in my procedure, but if they pick just one group_id number I only want it to return those records. Here is my procedure. When I run in Managment Studio it says I have errors near my if, then and else.
Any Ideas?? Thanks in advance!
CREATE PROCEDURE EMRUserSecurityGroups @group_id int
If @group_id = "*All" then
SELECT c.user_id,c.first_name,c.last_name, b.group_id, b.group_name
FROM user_group_xref a
JOIN security_groups b on a.group_id= b.group_id
JOIN user_mstr c on a.user_id=c.user_id
WHERE b.group_id IN ('5','20','21','23','24','25','26','27','28','29','32')
else
SELECT c.user_id,c.first_name,c.last_name, b.group_id, b.group_name
FROM user_group_xref a
JOIN security_groups b on a.group_id= b.group_id
JOIN user_mstr c on a.user_id=c.user_id
WHERE b.group_id = @group_id
