RE: Date in External Stored Procedure not as expected...

What sort of date value do you expect to get by passing blanks into a date-type? I'd guess that SQL tries to help by initializing the field to a default (and valid) date value.

Hi All,

I have the following stored procedure:

CREATE PROCEDURE CANLIB/GETSALES (
IN LISTTYPE VARCHAR(1) ,
IN ALLSTORES INTEGER ,
IN STORENUM INTEGER ,
IN MRKTREGION VARCHAR(1) ,
IN DSOREGION VARCHAR(1) ,
IN MISCREGION VARCHAR(1) ,
IN PEERGROUP VARCHAR(2) ,
IN STATE VARCHAR(2) ,
IN USERSTORES VARCHAR(50) ,
IN STOREGROUP INTEGER ,
IN DMA VARCHAR(30) ,
IN STARTDATE DATE ,
IN ENDDATE DATE ,
IN DATERANGE VARCHAR(3) )
DYNAMIC RESULT SETS 1
LANGUAGE RPGLE
SPECIFIC CANLIB/GETSALES
NOT DETERMINISTIC
READS SQL DATA
CALLED ON NULL INPUT
EXTERNAL NAME 'CANLIB/SPR0055 '
PARAMETER STYLE SQL ;
If I start a SEP on SPR0055 and call GetSales from iNav Run Sql Scripts
call getsales('I',1,0,'','','','','','',0,'','','0001-01-01','WTD');

When the program breaks (prior to the first executable statement) and I
press F5 (to execute the first statement) the value of the 12th parameter,
STARTDATE has a value of '2012-02-02' (today's date) even though I
specified ''.

Can anyone explain how or why STARTDATE is being populated with
'2012-02-02'?

Thanks in advance.
