Subj:   Operation ++

Hi,

I am trying out to find out a way to implement ++ or incremental operation in minimal effort in a stored procedure.

Here is the description -

One message is inserted for each step in a proc into a log table. I mention the step number as well -

     SET vLog_Msg = "STEP 1 : Insert into staging table."

     INSERT INTO Job_Log (vLog_Msg,..);

I want to automate the generation of sequence number for the steps so that even if I change the sequence of steps the number should be maintain the sequence -

     SET x=1;

     SET vLog_Msg = "STEP" || :x++ || " : Insert into staging table."

     SET vLog_Msg = "STEP" || :x++ || " : Update the staging table."

There could be more complex method to generate an identity numbers (CSUM, etc) but I am looking for some trick method to avoid extra work and performance degradation.


Thanks
