Hi Experts,  I've got the following code in MS-SQL-Server
 
DECLARE @TotAcct  VARCHAR(20)
SET @TotAcct =  (   SELECT COUNT(*) FROM ACCOUNT a )
PRINT 'Total Account:      ' + @TotAcct

Open in new window

Which works fine but I'm migrating it to DB2.  I have the following:
CREATE VARIABLE TotAcct  INTEGER;
SET TotAcct = (   SELECT COUNT(*) FROM ACCOUNT a);
DISPLAY 'Total Account:      ' + TotAcct;
DROP VARIABLE TotAcct;

Open in new window


Trouble is I cannot figure out how to print the output as I've done in SQLServer.

I'm probably just missing something.  Does anyone have any ides?

Which "flavor" of DB2 are you using? (mainframe, Unix, Linux, AS/400, etc)

Hi Mike,

DB2 is a lot different than SQL Server.  SQL Server is mostly a unified environment where the development environment (client) and the database server are tightly coupled.  The DB2 server is 100% independent of the development environment (except for them being compatible, of course).

As such, DB2 does not have a PRINT statement.  There are several free development environments available for DB2.  You could use the Store Procedure Editor and step through it to see the variables, or save the values to a debug table and inspect them later.  But PRINT to the output file just won't work.

I'm calling the script from the DB2CMD (which is connecting to DB2-9.2)  That being the case, I might be able to insert the lines into a temp DB and simply 'SELECT * FROM TMP;'  It's a pity that I can't actually display the contents of a variable though - that would have been ideal.


Thanks, Mike

If you're running the SQL as a script, you can always just SELECT xxx in the script and let the result get written to the output file.  That must be done from the script SQL though as that syntax of the SELECT statement won't work in a stored procedure.

That worked in the end.
