I am using IBM DB2 with Toad. I have a stored procedure that I need to debug.Any tutorial or videos on how to debug a stored procedure ? Echo statement won't work. One way would be to create a temp table, dump data in to it and open cursor at the end. But any alternative to this ?
I can't answer how to do this with Toad, but the (free) IBM Data Studio includes the ability to interactively debug stored procedures. You can set breakpoints, step through your procedure, see variable values during execution, etc.

I am using below command to load Object Storage file into DB2 table:NLU_TEMP_2.
CALL SYSPROC.ADMIN_CMD('load from "S3::s3.jp-tok.objectstorage.softlayer.net::
<s3-access-key-id>::<s3-secret-access-key>::nlu-test::practice_nlu.csv"
OF DEL modified by codepage=1208 coldel0x09 method P (2) WARNINGCOUNT 1000
MESSAGES ON SERVER INSERT into DASH12811.NLU_TEMP_2(nlu)');
above command inserts 2nd column from object storage file to DASH12811.NLU_TEMP_2 in nlu column.
I want to insert request_id from variable as a additional column:request_id in DASH12811.NLU_TEMP_2(request_id,nlu).
I read in some article to use statement concentrator literals to dynamically pass a value. Please let us know if anyone has an idea on how to use it.
Note, i would be using this query in DB2 but not DB2 warehouse. External tables wont work in DB2.
LOAD does not have any ability to include extra values that are not part of the load file. You can try to do things with columns that are generated by default in Db2 but it is not a good solution.
Really you need to wait until DB2 on Cloud supports external tables
I am not an expert in IBM Host tools as I am from development distributed side. Is there anyway that we can see the source code of IBM DB2 stored procedure in AQT tool. I know we can use any emulator tools like Attachmate Extra! X-treme, but the process seems very tough for me. To view a single stored procedure content, I had to type many number of commands. So I just thought it would be great if we have an option to view the same in a simple way, like we have sp_helptext in SQL SSMS (SQL Server Management Studio).
Update:
When I go to the Database Objects -> Procedures, all the schema's for different stored procedures are loading. And when I click on each schema, the stored procedures associated with that are loading, where I am able to see the procedure parameters, run procedure, create procedure etc. But I couldn't find any option to see the actual SQL query of the procedure.
When I click right click on procedure name and select View, I am getting options as,
Procedure Details
Procedure Params
User Access List
Package Access List
I am not seeing any option like Procedure Text. The language in Procedure Detail shows as COBOL and User Access List shows Execute G. Sorry that I can't provide any screenshots here, as it is the client machine I am working on.
Are you using the right tool for the job?
The AQT tool appears to be for procedures that are written in SQL, but your procedures appear to be COBOL stored-procedures. Source code for COBOL stored-procedures is normally managed outside of the RDBMS.
Talk with your DBA team or COBOL developers to find out which toolset at your site gives access to the source code for the COBOL stored procedures.
I wrote a stored procedure that calls openquery to a linked server to get data from a remote postgresql server and fill a table with that data. This is working fine. The stored procedure needs 3 parameters.
When I try to call the stored procedure from Report Builder 3.0 gives me error
7350 (cannot get the column OLE DB provider MSDASQL from linked server "name").
I already verify the allow in-process parameter in MSDASQL.
I can't find a solution for this. If I run the stored procedure from Mgmt Studio, it works fine. I'm using SQL Server 2012.
The report only have to show the file data by row. I can run the stored procedure and the report separately and works but I have to do this manually, my requirement needs a report subscription, so have to be automatic.
Any idea how to solve this or a workaround?
PD: sorry for my english, and thank you in advance.
Well I had to make separates works, so create a job that run the store procedure, generate the info on a table, and then run report reading the info from the table. This works.
Thank you all.
How to view the access plan for the entire SP along with the cost in IBM DataStudio, I am able to view it for a single query but when I do the same for a Stored Procedure it throws an error.
Found the answer, using db2expln executable from the command window, I was able to generate the execution plan for the stored procedures.
I have client utility that uses OLEDB to call a DB2 stored procedure. Inside the stored a procedure a cursor is opened so my utility can read record sets. Everything works fine but after a while of calling the same procedure over and over again, DB2 eventually throws an error that is related to the cursor being left open. Is there a sql command in DB2 to close the last used cursor or something similar?
I can't see how to do it from the client, but in the sp the code should be calling
Close CursorName;. Can you not update the procedure?
See here for an example.
