SQL Optimization Workflow

The SQL optimization workflow ensures that your SQL statements perform optimally in your database environment.

Procedure Description

Test Run SQL

The Test Run SQL function tests the performance of each alternative SQL Optimizer generates. This provides execution times for each alternative to determine the best statement for your database environment. Test Run SQL Alternatives
