when I configured the client to pmm-server on mysql system. In the dashboard ,the explain section shows: This type of query is not supported for EXPLAIN, and create section shows:SHOW CREATE TABLE t_fi_eas_record: Error 1046: No database selected. My fingerprit is 'SELECT * FROM t_fi_eas_record WHERE assist_account_content LIKE ? AND status !=? limit ?,?'. the server and client both are upgraded to the latest version:1.9.1,but the issues are sitll produced. could you help to check what the root causes about the issues. Thank you so much.
