Remarks
VODBSelect() is like DBSelect() but is strongly typed.
This function, however, does not call the error handler and will not, therefore, produce a runtime error message or create an error object if it fails.
Thus, it may be important to check the return value to determine if the function succeeded.
the LastRddError property in the runtime state. will contain needed information regarding any error that occurs.
See
