hi
i am working with WBIMB5.
The usual CopyMessageHeaders proc which comes with every ESQL module does not work for me if i move it to a common esql proc file and refer it from another esql. Intention was to move common, reusable code to a single place(like java).
Code -
CREATE PROCEDURE Copy_Message_Headers( IN InputRoot REFERENCE,
IN OutputRoot REFERENCE ) BEGIN
DECLARE I INTEGER 1;
DECLARE J INTEGER CARDINALITY(InputRoot.*[]);
WHILE I < J DO
SET OutputRoot.*[I] = InputRoot.*[I];
SET I = I + 1;
END WHILE;
END;
It behaves differently with 'IN', 'OUT' AND 'INOUT' for OutputRoot. But doesnt work in either case for me. As yet. Any advice/comment/help pl.
thanks |

How did you declare the OutputRoot reference ?
Did the OutputRoot tree exist prior to establishing a reference to it? |

Hi,
A reference to OutputRoot is not the same as the actual OutputRoot. I explained this in a post a long time ago on this forum. Please search for previous posts by me (mgk) to see the actual differences between the two.

What happens with 'IN' - if there are 2 headers, Properties and MQMD, then both get copied from InputRoot to OutputRoot fine within this proc.
But if this call is say in a compute node, then in my flow i have a RCD node next. The message goes into RCD node fine with Properties and MQMD, but comes out with 2 Properties trees, one correct and one with all NULL values. The MQMD disappears. I am calling this proc the first thing in Compute node, so the OutputRoot is empty/null when it goes in.
I hope this makes sense. |
