   # PR Description
   
   ### Motivation 
   
   When `DESC TABLE EXTENDED {fullTableName} AS JSON` fails to run, we will 
fallback base class `GetColumnsExtendedAsync` which 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 the `SqlState` = `42601` which is the error of 
SQL syntax error, it means the command is not supported by the runtime, then we 
can fallback to the base class 
   
   ### Changes
   - Update the fallback condition check in `Databricks` 
`GetColumnsExtendedAsync`
   
   ### Testing
   
   - End-to-end test with the runtime does not support the command
