How can I call a DB2 stored procedure with OUT parameters from SQuirreL SQL?

I really like SQuirreL SQL as a SQL query tool, but I've never been able to get it to call stored procedures in our AS/400 DB2 database. I always get the error "The number of parameter values set or registered does not match the number of parameters." I've double-checked the number of params and had no luck. This is the syntax I've tried for a procedure that takes one IN and one OUT:

call SOMESPROC(12345, ?);

I was able to cobble together some amalgamation of all of the above answers and came up with this which worked for me. I'm using Squirrel SQL 2018 connecting to an IBM AS/400 DB2 database. I did have to declare a statement separator, I used "#".

    BEGIN
        DECLARE success CHAR(1); -- output parameters
        DECLARE message CHAR(300);
        SET success = ' '; 
        SET message = ' ';
        CALL myProc('some', 'params', 4, success, message); 
        DECLARE GLOBAL TEMPORARY TABLE session.myTmp(s_res CHAR(1), m_res CHAR(300)) WITH REPLACE; 
        INSERT INTO session.myTmp(s_res, m_res) VALUES(success, message);
    END
    # -- <- statement separator needs to be set to something other than ";" in this case it's set to "#"
    SELECT * FROM session.myTmp;

through trial and error, I was able to see the results in Squirrel.

create or replace variable var4 char(1);
create or replace variable var5 decimal(3,0);
create or replace variable var6 char(60);
call getthedata('XXX',123456789,'1234567',var4,var5,var6);
select var4,var5,var6 from sysibm.sysdummy1;  -- displays OUT parms

This will work in Squirrel if you change the delimiter (as specified above). However, to see what the variable is, you need to do the following...

In my example, I will set the delimiter to a tildy (~). Include after last "end", before "select". Code begins here...

begin
declare inoutParm numeric(2,0);
call spMyStoredProcedure(
             1234567                                     
           , inoutParm                                           
       );
declare global temporary table session.myTempTbl  
       (MyResult   char(1024) )                                         
with replace ;
insert into session.myTempTbl
  (myResult)
   values(inoutParm) ;  
end
~
select myResult from session.myTempTbl

It seems that SQuirrel currently is not capable of doing that on AS/400 DB2.

Using the open source "SQL Workbench/J" (http://www.sql-workbench.net/) I was able to call a procedure:

wbcall SOMESPROC(12345, ?);

It has its own command for calling a procedure "wbcall". Use ? for out parameters.

Note: While installing SQL Workbench/J make sure to download the right DB2 driver from IBM and also add the licence file while adding the driver inside SQL Workbench/J.

Here is an tested example which works on Squirrel 3.7 with a db2 stored procedure . The trick is to passe with an transitional stored procedure MY_PROC_TEST to call the real stored procedure PROC_TEST.

change statement separator in squirrel > session > session properties > SQL : @

DROP PROCEDURE MY_PROC_TEST()@
CREATE PROCEDURE MY_PROC_TEST()
RESULT SETS 1 -- out resultset (call product)
LANGUAGE SQL
BEGIN
  DECLARE flag SMALLINT; -- out parameter
  CALL MY_PROC('2015', flag);
END @
CALL MY_PROC_TEST()@
END @

Then you can call the sored procedure like this :

CALL MY_PROC_TEST()@

In Squirrel you can use something like this. You'll want to make sure the type of the declared variable matches the type of your out parameter in the stored procedure.

BEGIN
    DECLARE outParam INT;
    STORED_PROC_NAME(outParam);
END

If you also need to provide input for the procedure you could do this.

BEGIN
    DECLARE outParam INT;
    STORED_PROC_NAME('input', outParam);
END

You also need to change the statement separator to something other than ;. Otherwise it will break up the statement and try to send each piece individually.

In the pro version of DbVisualizer, with the "Process Parameter Markers in SQL" under the SQL Commander menu option enabled, it will allow the "?" param

call SOMESPROC(12345, ?);

change statement separator in squirrel > session > session properties > SQL : '#' 

BEGIN
    DECLARE inOutParam varchar(200);
    set inOutParam =  'a value';
    STORED_PROC_NAME(outParam);
END;

I would think that if there is one in then the call should be:

CALL SomeSProc(12345)

to get a result maybe try:

SELECT * FROM SomeSProc(12345)
