To be honest, I don't how to do this with an event monitor. If the queries are dynamic SQL instead of embeded static SQL, using a "get snapshot for dynamic SQL ..." is the easiest way to do this. You will need to turn on the statement monitor at the instance level, or turn it on only for that session using "update monitor switches...".
Dynamic SQL would be used for any Java interface or script. Static SQL is used in an SQL stored procedure, function, or triggers, or in a language such as C where the program is compiled and a bind is done on the associated DB2 package.
