ODBC_SetErrorHandler ( metodoErro ) 
Parâmetro Tipo   Descrição
metodoErro  String in Error method to be invoked, or Empty string to stop trapping errors

The ODBC_SetErrorHandler command installs an error-handling method that will handle the errors for all processes and 4D ODBC PRO will no longer display the alert informing you of invalid connection and/or statement IDs.

The called method will receive 2 parameters in $1 and $2:

  • $1 gets the error number,
  • $2 gets the error text.

Note: Due to database compilation, $1 and $2 must be declared respectively as longint (C_LONGINT) and text (C_TEXT) in the error method.

The method installed by this command can use the ODBC_SQLGetDiagRec routine to get more information on the error.

To uninstall the error handling method, pass an empty string to ODBC_SetErrorHandler.
