Reading, writing and reporting on queries

Published: 10 Jun 2004
Do you know of either a script or bat file that can read 100 individual query files, connect to a database, do EXPLAIN on each query and write the EXPLAIN report on each query in batch mode?
Sorry, I don't have a ready-made script for you, but there are a number of ways you can do this and it would be a worthwhile exercise to develop a utility. One possibility is to store the queries in a database table, and in a PL/SQL procedure, fetch each query and then perform the EXPLAIN (the results go into PLAN_TABLE; it can hold the results of all 100 queries--just be sure to give each query an ID when you issue the EXPLAIN command). Finally, you can write a query to fetch the plans from the PLAN_TABLE, and save the results to a file.
