A computerized method of intercepting SQL processing within a relational database. The relational database includes a relational database management program having SQL processing logic. The method includes the steps of: (a) enabling an SQL intercept code by connecting directly into the SQL processing logic of the relational database management program; (b) using the SQL intercept code to intercept an SQL statement made to the relational database; (c) using the SQL intercept code to collect a first set of real-time SQL performance information located in selected structures of the relational database; (d) returning control to the SQL processing logic until the relational database management program has processed the SQL statement to completion; (e) using the SQL intercept code to collect a second set of real-time SQL performance information located in the structures; (f) comparing the first set with the second set in order to measure the performance of the SQL statement; and (g) returning control to the relational database management program.
