The performance of queries made against large database tables is considerably improved when the columns in the ``++where++`` clause are indexed. If all the columns in the ``++where++`` clause are included in an index, then the selection can be made directly against the index, but using even a single indexed column can improve performance. Therefore, indexes should be created on large tables to improve query performance.
@Ann, according to this RSPEC, the COBOL language is covered but I don't see the relating Jira ticket in the COBOL project ?
