You can use parameters in the WHERE clause of a table pair or single table. Use parameters in the WHERE clause to dynamically change the WHERE clause after each test run.
When you run a test on a single-table constraint or table pair that has a parameterized WHERE clause, Data Validation Option looks up the value of the parameter from the parameter file and passes the WHERE clause filter to the PowerCenter Integration Service.
To look up the parameter value, the Data Validation Client or the DVOCmd command line that runs the tests must have access to the parameter file.
