RE: mysql EXPLAIN [tablename] in CFQUERY?
Here's a question for you, the datasource that's doing this has to be using a specific db before you can explain / describe a table. From a command line, you have to type: use db; explain table; Otherwise, you have to type: explain db.table; So, if you're creating a DSN that doesn't point to a particular database, you will have to: cflock timeout=60 throwontimeout=No name=showTblLock type=EXCLUSIVE cfquery name=useDb datasource=#request.dsn# use #arguments.db# /cfquery cfquery name=getTables datasource=#request.dsn# SHOW TABLE STATUS /cfquery /cflock HTH, ~Todd On Wed, 21 Aug 2002, Lon Lentz wrote: They both work from the command line.
