When creating the necessary rules to enable SQL logging using DBQL, a rule correlates exactly to a specific SQL statement. For example, the following SQL statements show a BEGIN QUERY LOGGING statement along with its corresponding END QUERY LOGGING statement.
BEGIN QUERY LOGGING WITH SQL ON ALL ACCOUNT='$M00MSIR&D&H'; END QUERY LOGGING WITH SQL ON ALL ACCOUNT='$M00MSIR&D&H';
The implication is that the SQL used to create the various rules should be retained so as to easily facilitate removing a rule.
The preceding account string format is considered a best practice. For more information, see Logging Resource Usage Data with Account String Variables.
All rules can be easily removed by the following command:
END QUERY LOGGING ON ALL RULES;
