Hello,

Is it possible to obtain MySQL_ERRNO in a DataBase Exception ?

Thanks.

It depends on exception class.
If exception raises MySQLxxConnection then exception should be
ESQLDatabaseError.
This exception class has fields:
- ErrorCode which is MySQLErrNo
- SQLState

But if exception for example raises TDataSet then exception is of type
EDatabaseError, which of course cann't contain MySQL error number.
