OLE DB Command And Stored Procedure That Returns Value And/or Error
May 23, 2006
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
PJ

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.

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.

I have a process that is running on the os. This process is picking up FTP files every 5 min, it renames them so not to confuse them with the new files, copies all renamed files into one file to be used by bulk insert, runs the bulk insert to populate a table, and then runs the stored procedure that scrubbing the data and insert it into another table. For every transaction that I do in my stored procedure, I do the error checking as follows:
IF @@error <> 0
BEGIN
ROLLBACK TRANSACTION
RETURN
If my stored procedure encounters an error, return statement will stop it from running. If this happens, I need to stop the process that is running on the os as well.
Questions:
How can that be accomplished?
How to restart the stored procedure ones the error has been corrected?
Thank you for your help.

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.

Hi,
I need to know whether a stored procedure returns only a single record or it can return more than one if the query if for example to return all records in a specific date range.
Thanks.

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.

I have a stored procedure
Code Block
CREATE PROCEDURE WEA_SelectEmployeeListByCourseOrProject
@ProjectID int,
@CourseID int,
@blnIsSearch int,
@strUserName nvarchar(20)
AS
SET CONCAT_NULL_YIELDS_NULL OFF
DECLARE @strRole nvarchar(15),
@ContactID int
SELECT @strRole = Role, @ContactID = ContactID FROM Contact WHERE UserName = @strUserName
Select DISTINCT Contact.ContactID ID, UPPER(Surname + 'gd ' + Forename ) AS Description, UPPER(Surname + ' ' + Forename + ' ' + ContactReference) AS Description_CR

AND
(@ProjectID = 0 OR COALESCE(AssignedEmployee.ProjectID,0) = @ProjectID)
AND
(
(@strRole = 'MIS_TUTOR' AND

)
OR
(@strRole <> 'MIS_TUTOR')
)
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
SET CONCAT_NULL_YIELDS_NULL OFF
DECLARE @ProjectID int,
@CourseID int,

)
OR
(@Role <> 'MIS_TUTOR')
)
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
Regards
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?

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 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?

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

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...!

Hi fellows
I am working in a formula about drilling machine. This machine sends the inofrmation to the server basically the name of a blasthole, revolution,pulldown and so on. I have another database with information of the same blasthole, but with different items such as drill diameter,site,area and so on, so i have two tables with information, but both of them have the same blasthole that means that i can relate with a join and identify each blasthole. but teh main point is that i have a specific column con a distance that the machine is drilling for example in a certain moment this machine is drilling 1 feet 3 feet 4 feet until to reach the bottom of a limit. his
My problem is that i want to create a from to for those distances.
table 1
pk diameter bench
dh1 12.5 4050
table 2
blasthole depth
dh1 1.2
dh1 3.5
dh1 4.7
dh1 5.4
dh1 8.3
dh1 15
with a join i can obtain something like this
view 1
blasthole diameter bench depth
dh1 12.5 4050 1.2
dh1 12.5 4050 3.5
dh1 12.5 4050 4.7
dh1 12.5 4050 5.4
dh1 12.5 4050 8.3
dh1 12.5 4050 15
the most difficult part is to include a new colum taht can start with 0 and to obtain teh previus value from depth something like this
view 1-A
blasthole diameter bench from depth
dh1 12.5 4050 0 1.2
dh1 12.5 4050 1.2 3.5
dh1 12.5 4050 3.5 4.7
dh1 12.5 4050 4.7 5.4
dh1 12.5 4050 5.4 8.3
dh1 12.5 4050 8.3 15
I was thinking to create a pk2 in order to know how many values have each blasthole and create a loop and maybe i can organize the column from something like this
pk2 blasthole diameter bench from depth
1 dh1 12.5 4050 0 1.2
2 dh1 12.5 4050 1.2 3.5
3 dh1 12.5 4050 3.5 4.7
4 dh1 12.5 4050 4.7 5.4
5 dh1 12.5 4050 5.4 8.3
6 dh1 12.5 4050 8.3 15
I hope that somebody can understand my question, but i think is a hard one for the forum
cheers

How do you use a variable in the ORDER BY command in a sql statement.
I currently have:
****************************************
CREATE Procedure SS_POList
(
@CompanyID nvarchar(10),
@PO varchar (20) = '%'
)
As
SELECT
SS_Sendback.EndUserPO,
SS_Sendback.PO,
COUNT(SS_Sendback.EndUserPO) as pocount,
SUM(SS_Sendback.Customerprice) as totcost
FROM
SS_Sendback
WHERE
SS_Sendback.EndusercustomerNumber = @CompanyID
AND
SS_Sendback.EnduserPO Like @PO
GROUP BY
SS_Sendback.EndUserPO,
SS_Sendback.PO
ORDER BY
SS_Sendback.PO
GO
*************************************
I changed it to
*************************************
CREATE Procedure SS_POList
(
@CompanyID nvarchar(10),
@PO varchar (20) = '%',
@Order varchar(20)
)
As
SELECT
SS_Sendback.EndUserPO,
SS_Sendback.PO,
COUNT(SS_Sendback.EndUserPO) as pocount,
SUM(SS_Sendback.Customerprice) as totcost
FROM
SS_Sendback
WHERE
SS_Sendback.EndusercustomerNumber = @CompanyID
AND
SS_Sendback.EnduserPO Like @PO
GROUP BY
SS_Sendback.EndUserPO,
SS_Sendback.PO
ORDER BY
@Order
GO
and I receive the following error..
error1008: the select item identified by the Order By number 1 contains a variable as part of the expression identifying a column position. Variables are only allowed when ordering by an expression referencing a column name.
How does it know @order is a position and not a column name... It's a variable. I'm obviously doing something wrong. Can someone help.
Thanks

I have a problem where bcp command is called and executed successfully sometimes but fails randomly.My stored procedure looks like this:
select @SQL = 'select * from [' + @RepositoryName + '] where ( IsNumeric([' + @PhoneField + ']) = ' + CONVERT(varchar(1), @FALSE) + ' OR LEN([' + @PhoneField + ']) <> ' + CONVERT(varchar(2), @ValidLength) + ')'
execute(@SQL)
set @Count = @@ROWCOUNT
if @Count > 0
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE
[code]....
The above procedure is called 4 times from another procedure by passing appropriate parameters. Most of the time, it executes successfully for 2 times before failing. When I try to debug, it always hangs at EXEC master..xp_cmdshell @CommandSQL. The task manager shows bcp.exe as running at this point. Interestingly, the required rows are exported using the bcp command, but the stored procedure does not move further until bcp.exe is manually stopped from the task manager.

Hi!I already sent this to the ACCESS newsgroup. But since I do not know reallywhich side is really causing the problem, I have decided to send thisinquiryto this newsgroup also, if I may.Below is the environment of the application:a. MS Access 2003 application running on Windows XPb. SQL Server 2000 - backend running MS Server 2003 OSBelow is the code that is giving me an error:Dim com As ADODB.CommandSet com = New ADODB.CommandWith com.ActiveConnection = "DSN=YES2;DATABASE=YES100SQLC;".CommandText = "sp_Recalculate".CommandType = adCmdStoredProc.Parameters.Refresh.Parameters("@ItemNumber") = ItemNum.Execute ' This is where it hangs up...TotalItems = .Parameters("@TotalInStock")TotalCost = .Parameters("@TotalCost")End WithSet com = Nothingand the store procedure is:CREATE PROCEDURE DBO.sp_Recalculate@ItemNumber nvarchar(50),@TotalInStock int = 0,@TotalCost money = 0ASBEGINSET @TotalInStock = (SELECT Sum([Quantity in Stock])FROM [Inventory Products]WHERE [Item Number] = @ItemNumber)SET @TotalCost = (SELECT Sum([Cost] * [Quantity in Stock])FROM [Inventory Products]WHERE [Item Number] = @ItemNumber)ENDWhen the process goes to the ".Execute" line, it hangs up for a long timethen gives me an error message "Everflow". I have been trying to solvethis issue but do not have an idea for now of the cause.Below is my finding:a. When I run the stored procedure in the SQL analyzer, it works just fine.I placed a SELECT statement to view the result of the stored procedure.It gives the correct values.Can anyone have ideas or similar problems?Thanks.

Hello,
Stuck in a spot and hoping someone will nudge me in the right direction....
I'm trying to write to a sql db via a storedprocedure using a parameter. i'm pretty certain the below statement is causing the problem. but i'm not sure how to properly refer to it....
Dim connString As String
connString = "integrated security=false;user id=sa;server=HCENT1;database=LicenseRenewal;persist security info=False"
Dim myConnection As New SqlConnection(connString)
Dim myCommand As New SqlCommand("InsertPage1", myConnection)
myCommand.CommandType = CommandType.StoredProcedure
' .......other (working) parameter statements.........
Dim parameterDates As New SqlParameter("@Dates", SqlDbType.VarChar, 4000)
parameterDates.Value = Session("lstDates")
myCommand.Parameters.Add(parameterDates)
myConnection.Open()
myCommand.ExecuteNonQuery()
myConnection.Close()
the session("lstDates") is the contents of lstDates.Items (listbox) from a previous page.
i'm guessing its not valid to refer to it as a varchar, can someone point me to the proper way to handle this?

Hi everybody, I would like to know if it's possible to execute a stored procedure, passing it parameters, using not CommandType.StoredProcedure value of sqlcommand, but CommandType.Text.
I tried to use this:
sqlCmd.CommandType = CommandType.Text
sqlCmd.Parameters.Add(sqlPar)
sqlCmd.ExecuteNonQuery()
With this sql command:
"exec sp ..."
I wasn't able to make it to work, and I don't know if it's possible.
Another question:
if it's not possible, how can I pass a Null value to stored procedure?
This code:
sqlPar = new SqlParameter("@id", SqlDbType.Int)
sqlPar.Direction = ParameterDirection.Output
cmd.Parameters.Add(sqlPar)
sqlPar = new SqlParameter("@parent_id", DBNull)
cmd.Parameters.Add(sqlPar)
doesn't work, 'cause I get this error:
BC30684: 'DBNull' is a type and cannot be used as an expression.
How can I solve this?
Bye and thanks in advance.
P.S. I would prefer first method to call a stored procedure ('cause I could call it with 'exec sp null' sql command, solving the other problem), but obviusly if it's possible...=)
Sorry for grammatical mistakes.
