PR Description
Motivation
When
DESC TABLE EXTENDED {fullTableName} AS JSONfails to run, we will fallback base classGetColumnsExtendedAsyncwhich calls 3 metadata query to get the info, but the current check is based on the error message, which is not accurate, instead, we can check theSqlState=42601which is the error of SQL syntax error, it means the command is not supported by the runtime, then we can fallback to the base classChanges
