just purchased a license for this tool just to find out that only select queries can be explained. what about other other like "insert table name... select ....." type of queries ?
let me know if you have plans to support more than just select queries.
We support explaining UPDATE, DELETE, INSERT, REPLACE by simple rewriting to a corresponding SELECT. We do support simple "INSERT ... SELECT ... " queries too, but there are some cases which we do not yet support.
Can you provide more details on the query you're having troubles with?
