Driver Manager Diagnostic Example

  • Artykuł

The Driver Manager can also generate diagnostic messages. For example, if an application passed an invalid direction option to SQLDataSources, the Driver Manager might format and return the following values from SQLGetDiagRec:

SQLSTATE:         "HY103"  
Native Error:      0  
Diagnostic Msg:   "[Microsoft][ODBC Driver Manager]Direction option out of range"

Because the error occurred in the Driver Manager, it added prefixes to the diagnostic message for its vendor ([Microsoft]) and its identifier ([ODBC Driver Manager]).
