Alternative for Command Task in Informatica

[venku72]

Hi All,

We using a command task in our Workflow.
In command task we are getting Max_seq_id from a table in target.
We are storing the value in a parameter file.
We are using a sql query to store the value in the $$paramenter.

In the SQ we are usign the $$max_seq_id to comare with source sequence id.
Condition is as follows

Select seq_id,bla, bla, bla
Whre seq_id > $$max_seqID.

Now we want to eliminate the the command task and implement this logic in mapping/workflow itself.

How to do this?

Pls help me..in this

You can set up a variable in the mapping that gets set/updated with an Expression Transformation using the SETVARIABLE command.

Doing this, the value becomes part of the Session's "Persistant Value". In other words you can run a SQL Override filtering on the value of the variable, just as you show in your example.

The value remains in the Session, so the next run can use the value from the previous run.

I would look into that option.
