EJvCsvKeyError

run\JvCsvData.pas

Summary

Exception class for CSV key errors. Invalid or duplicate primary key.

run\JvCsvData.pas

Pascal

 run\JvCsvData.pas

 EJvCsvKeyError = class(EDatabaseError);

Description

This class is used, instead of just raising a bare Exception, so you can craft your exception handling. If you are doing a dataset operation and you want to handle only errors raised by a TJvCsvDataSet that are due to invalid/duplicate primary keys.
try
MyDataSet.DoSomething;
except
on E:EJvCsvKeyError dobegin


 NotifyUserPrimaryKeyIsInvalid;
end
end;
