Script to terminate BODS Job on condition

Scenario: We have a metadata table for extract runs, before running an extract job, we need to check whether the previous run was successful. This can be done in Data Services using scripting.

Solution:

Use the following script

if ( sql('DS_Datastore_Name','SELECT EXTRACT_STATUS FROM EXTRACT_RUN WHERE EXTRACT_NAME ='Extract 1') != 'Completed'  )
begin
raise_exception_ext( 'Job terminated due to error in previous run. Correct the previous load and re-run again',1);
end

In the above code, we write a script where in we use an if condition and inside the if condition with the help of a SQL function, we write code to check if the previous run was completed or not.  If not completed, it goes inside the if condition where we have written the below code,

raise_exception_ext( 'Job terminated due to error in previous run. Correct the previous load and re-run again',1);

This code will make sure that a exception is raised and there by failing the job.
