How Can I Assign A Stored Procedure As Cursor's Data Source In AStored Procedure?
Oct 8, 2007
How can I create a Cursor into a Stored Procedure, with another Stored Procedure as data source?
Something like this:
CREATE PROCEDURE TestHardDisk
AS
BEGIN
DECLARE CURSOR HardDisk_Cursor
FOR Exec xp_FixedDrives
-- The cursor needs a SELECT Statement and no accepts an Stored Procedure as Data Source
OPEN CURSOR HardDisk_Cursor
FETCH NEXT FROM HardDisk_Cursor
INTO @Drive, @Space
WHILE @@FETCH_STATUS = 0
BEGIN
...
END
END

I currently have a process that has a cursor. It takes data and executes a stored procedure with parameters.
declare @tmpmsg varchar(max)
declare @tmpmsgprefix varchar(max)
declare @cms varchar(20)
create table #tmpIntegrity(matternum varchar(10),ClientName varchar(20))
insert into #tmpIntegrity(matternum,ClientName)
[Code] ....
Output from code:
The following Client1 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3,Ac4,
The following Client2 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3,
The following Client3 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3,
The following Client4 accounts have A1 value and a blank A2 field. Accounts:
Desired output (no trailing comma):
The following Client1 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3,Ac4
The following Client2 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3
The following Client3 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3
The following Client4 accounts have A1 value and a blank A2 field. Accounts:
Next, how do I call the stored procedure without doing it RBAR? Is that possible?
execute usp_IMessage 832,101,@tmpmsgprefix,@tmpmsg,','

Here is the scenario,
I have 2 stored procedures, SP1 and SP2
SP1 has the following code:
declare @tmp as varchar(300)
set @tmp = 'SELECT * FROM
OPENROWSET ( ''SQLOLEDB'', ''SERVER=.;Trusted_Connection=yes'',
''SET FMTONLY OFF EXEC ' + db_name() + '..StoredProcedure'' )'
EXEC (@tmp)
SP2 has the following code:
SELECT *
FROM SP1 (which won't work because SP1 is a stored procedure. A view, a table valued function, or a temporary table must be used for this)
Views - can't use a view because they don't allow dynamic sql and the db_name() in the OPENROWSET function must be used.
Temp Tables - can't use these because it would cause a large hit on system performance due to the frequency SP2 and others like it will be used.
Functions - My last resort is to use a table valued function as shown:
FUNCTION MyFunction
( )
RETURNS @retTable
(
@Field1 int,
@Field2 varchar(50)
)
AS
BEGIN
-- the problem here is that I need to call SP1 and assign it's resulting data into the
-- @retTable variable
-- this statement is incorrect, but it's meaning is my goal
INSERT @retTableSELECT *FROM SP1
RETURN
END

Is it possible to use a stored procedure in a Data Source View? When I use the wizard to create the Datasource View, all it lets me choose is tables and views in the database. Am I missing something, or trying to do something that is impossible?

Simple question - can I use an external stored procedure for my data flow source. I assume that I can use the OLEDB connection and go from there?
Can I use SQL command and do exec sp_thisprocedure?
Thanks for the information.

Hi,
I have a SSIS package which exports data from a view in SQL database into Excel file. It was created by Export Wizard in SQL 2005 Server.
Now I would like to modify this package and change data source from view to stored procedure.
What component from toolbox should I use? it should be placed in Control Flow or Data Flow? And how connetc it with my Excel Destination?
thanks,

This seems to be much more difficult than it was in DTS (or perhaps I just need to adjust to the new way of doing things).
Eventually I found that I needed to use "SQL command from variable" and using two other variables as input parameters. The expresion for the command is
"usp_ValveStatusForDay '" + @[User:ate] + "','" + @[User::Report] + "'"
which typically evaluates as
usp_ValveStatusForDay '18 Oct 07','Report_Name'
This previews correctly and the resulting columns are available for mapping to a destination. So far so good.
By the way, is this the best way to call a stored procedure with parameters?
I have pasted the stored procedure at the end of this posting because I have come accross a puzzling problem. The query as shown below works correctlly but if I un-comment the delete statement, the preview still works and the columns are still avilable for mapping but I get the following errors when the package is executed.
Error: 0xC02092B4 at Data Flow Task, OLE DB Source [1]: A rowset based on the SQL command was not returned by the OLE DB provider.
Error: 0xC004701A at Data Flow Task, DTS.Pipeline: component "OLE DB Source" (1) failed the pre-execute phase and returned error code 0xC02092B4.
I realise that I could execute the delete query in a separate SSIS package step but I am curious as to why there is a problem with the way I tried to do it.
At one stage the stored procedure used a temp table and later I also experimented with a table variable. In both cases I got similar errors at execution time. In the case of the temp table there was another problem in that, while the preview worked, there were no columns available for mapping. Using a table variable seemed to overcome this problem but I still got the run time error. eventually I found a way to avoid using either a temp table or a table variable and the package then worked correctly, copying the data into the desitnation table.
It seems to me that if there is any complexity at all to the stored procedure, these errors seem to occur. Can anyone enlighten me as to what the "rules of engagement" are in this regard? Is one solution to use a wrapper stored procedure that simply calls the more complex one?
ALTER procedure [dbo].[usp_ValveStatusForDay]
(
@dateTime DateTime,
@reportName VarChar(100)
)
AS
BEGIN
DECLARE @day VarChar(10)
DECLARE @month VarChar(10)

The goal is to address visual source safe database on the network. We have the srcsafe.ini in the network as \ipaddrsrcsafe.ini. Now I create a new VSSDatabase object and call its OpenDb. Well for simple consle app or winform it is ok. But I was running it under Sql server Stored Procedure. It failed for I cannot access the source safe path throgh the COM object.
I know it is because of Windows identity. So I add the following code before I want to open the database, changing the to the WindowsIdentity:
WindowsIdentity impersonId = SqlContext.WindowsIdentity;
WindowsImpersonationContext orgCtx = null;
try
{
orgCtx = impersonId.Impersonate();
VSS_Database = new MVSI.VSSDatabase();
// VSS_Database.ImpersonateCaller = true;
VSS_Database.Open(Path, UserName, PassWord);
}
catch (Exception err)
{
orgCtx.Undo();
throw err;
}
finally
{
orgCtx.Undo();
}
Without the commented line "// VSS_Database.ImpersonateCaller = true", this does not work at all. It just behave like no changes to the windows identity.
However if I add this code, well, OpenDb will result in a No-response query. The Sql server is running the query with no responses.
Have you ever met that before? I am really frustrated. Thanks

I have created a stored procedure on the iSeries that creates a cursor and opens it. I am trying to write my report to use the stored procedure. I cannot get the data source to work. How do I create my data source so that it uses the stored procedure? My SP has three parameters I am trying to pass from the report. The parms are created in the layout.

I have a MSSQL2000 table called partspec.dbo.locationIn this table are 2 smallint columns: Tester (numbered 1-40) and Line (numbered with various integers)I am trying to create a stored procedure to read the tester number like so:Select Tester from partspec.dbo.location where Line = 2which will return up to 5 tester number results, lets say 11, 12, 24, 29 ,34My question is how do I store these tester numbers into 5 variables so that I may use them later in the sp ? So it would go something like this:CREATE PROCEDURE Table_Line
(@Tester1 integer,@Tester2 integer,@Tester3 integer,@Tester4 integer,@Tester5 integer)ASSELECT Tester FROM partspec.dbo.location where Line = 2Now this is where I'm confused on how to get 1 value into 1 variable and so on for all 5 values returned. This is what I would like to happen:
@Tester1 = 11@Tester2 = 12@Tester3 = 24@Tester4 = 29@Tester5 = 34GOThank you for any and all assistance.

I am using execute sql task to run a stored procedure in oracle database which returns a resultset. This works. Now I need to send the ouput to a destination table in a sql database. Should I use for each loop to pick the resultset and insert it into the destination one by one (which I dont think is a great idea) or is there a better way to accomplish this task (in data flow task) ?
When I use dataflow task instead of execute sql task, the main issue is I am not able to see the output columns when I execute an oracle stored procedure, but when I see the preview I can see the resultset . But I can see the output columns for a sql server stored procedure.

I have a stored procedure that basically recieves the where clause of a select statement and executes the new sql statement... ie:
CREATE PROCEDURE [dbo].[bsa_GetImportIDs]
(@FilterText varchar(1000))
AS
DECLARE @MySQL varchar(1000)
SET @MySQL = "SELECT Import_ID FROM tblImport WHERE " + @FilterText
EXEC (@MySQL)
GO
Now, in another stored procedure, I need to use the stored procedure above in a cursor so that I can execute an insert statement for each occurance of the Import_ID that appears in that dataset... ie:
CREATE PROCEDURE [dbo].[bsa_PutLargeCase]
AS
DECLARE @CaseID uniqueidentifier
SET @CaseID = NewID()
Declare @ImportID uniqueidentifier
Declare curClient Cursor FAST_FORWARD for
SELECT Import_ID FROM dbo.bsa_GetImportIDs (@FilterText) <---- this does not work!!!
Open curClient
FETCH NEXT FROM curClient INTO @ImportID
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC dbo.bsa_PutCaseDetail @CaseID, @ImportID
FETCH NEXT FROM curClient INTO @ImportID
END
CLOSE curClient
DEALLOCATE curClient
GO
How can I utilize my first stored procedure in the cursor of the second? ... or
Are there any other approaches that may be a better solution to what I am trying to accomplish?
Thanks in advance for any input.

Hi,
I have created the following stored procedure to get the text from one table and compare with them with another table and the one's that match will assign the corresponding ID. But the problem is that it only assigns the last id in the table from the main table which new_cur2 holds. So the problem is that its not updating with the correct ID its just updating with the last ID the cursor holds. Does any one know what it could be.....I think it may just be a little coding error....thanks

Can someone post some code that shows a Stored Procedure receiving a cursor that it can process - lets say a group of order detail records are received that must be saved along with the single Order header record.
And, in another example, a SP returns a result set to the calling program. - For example, a particular sale receipt is pulled up on the screen and the order detail is needed.
Thanks for help on this,

Hi,
I have a kind of problem. In SQL Server I have a stored procedure ressembling this:
Code Block
ALTER PROCEDURE procedure1
(
@param int
)
SELECT * FROM table WHERE param = @param
Now I want to call this procedure and pass it to a cursor. We all know you can do this:
Code Block
DELCARE cursor1 CURSOR for
SELECT * FROM table WHERE param = @param
.. , but I want something like this:
Code Block
DECLARE cursor1 CURSOR for
EXEC procedure1 @param
Is it possible? I could solve it in another, but then I have to connect 2x to the database, which is less performant.
I have also tried something like this:
Code Block
ALTER PROCEDURE procedure1
(
@param int
)
SELECT @test = id FROM table WHERE param = @param
RETURN @test
ALTER PROCEDURE procedure2
(
@param int
)
DECLARE @var varchar(100)
EXEC @var = procedure1 @param
But then it returns always 0.
So is there a way to pass a procedure's select to a cursor?
Thanks in advance

I appear to be having an issue where the @LetterVal and @Numeric variables aren't resetting for each loop iteration, so if no results are found, it just returns the previous loops values since they aren't overwritten. Below is the stored procedure I've created:
ALTER PROCEDURE [dbo].[ap_CalcGrade]
-- Add the parameters for the stored procedure here
@studId int,
@secId int,
@grdTyCd char(2),
@grdCdOcc int,
@Numeric int output,
[Code] ....
And below is the "test query" I'm using:
-- *** Test Program ***
Declare @LetterVal varchar(2), -- Letter Grade
@Numeric int, -- Numeric Grade
@Result int -- Procedure Status (0 = OK)
Execute @Result = dbo.ap_CalcGrade 102, 86, 'QZ', 3,
[Code] ....
This is resulting in an output of:
A+ 97
A+ 97
C- 72
but it should be returning the output below due to the 2nd data set not being valid/found in the sp query:
A+ 97
No Find
C- 72
I'm sure this is sloppy and not the most efficient way of doing this, so whats causing the errant results, and if there is any better way I should be writing it. Below is the assignment requirements:
Create a stored procedure using the STUDENT database called ap_CalcGrade that does the following:
1. Accepts as input STUDENT_ID, SECTION_ID, GRADE_TYPE_CODE, and GRADE_CODE_OCCURRENCE
2. Outputs the numeric grade and the letter grade back to the user
3. If the numeric grade is found, return 0, otherwise return 1
4. You must use a cursor to loop through the GRADE_CONVERSION table to find the letter grade

My server is MS Sql Server 2005. I'm using com.microsoft.sqlserver.jdbc.SQLServerDriver as the driver class. I've established a connection to the database.
I'm trying to invoke a stored procedure using JDBC and a callable statement. The stored procedure has a parameter @CurOut CURSOR VARYING OUTPUT. How do I setup the callable statement so the output parameter is accepted by the driver?
I'm not really trying to pass a cursor up to the database Server but I'm wanting a cursor back from the stored procedure that is other than the result set or other value the stored procedure returns.
First problem: What java.sql.Types (or SQL Server specific) value do I specify for the out parameter I'm registering on the CallableStatement?
Second problem: What do I set the value of the parameter to?
The code looks like:
CallableStatement cstmt = myConnection.prepareCall(sQuery);
cstmt.registerOutParameter(1, Types.OTHER); // What is the right type?
cstmt.setNull(1, Types.OTHER); // What is the right type?
if (cstmt.execute()) {
ResultSet rs = cstmt.getResultSet();
}
Execution results in a NullPointerException from the driver.
What am I doing wrong?
Thanks for your assistance.
