Q1. How will you use two different DB2 qualifiers in a single COBOL program? Suppose we have 2 tables EMP1 and EMP2 with same structure defined in two different DB2 qualifiers QUAL1.EMP1 and QUAL2.EMP2 now during first 15 days we want to use QUAL1.EMP1 and rest of the days QUAL2.EMP2 how will we do this. We can create a single program and a single load for this program.
