> I would like silent this exception on global app.

Do you have the source code, or you want to suppress
that message on the system level ?

If you have the source code, that depends on the database
system you use. For example, for ADO:

void __fastcall TDataModule::ADOTablePostError(TDataSet *DataSet,
      EDatabaseError *E, TDataAction &Action)
{
   // No system error message
   Action = daAbort;

   // ... other checkings ...

   // ...
   if ( StrPos( E->Message.c_str(), "zero-length"                  ) ||
        StrPos( E->Message.c_str(), "Null value"                   ) ||
        StrPos( E->Message.c_str(), "must have a value"            ) ||
        StrPos( E->Message.c_str(), "Error in row"                 ) ||
        StrPos( E->Message.c_str(), "not a valid date"             ) ||
        StrPos( E->Message.c_str(), "Datetime field overflow"      ) ||
        StrPos( E->Message.c_str(), "related record is required "  ) ||
        StrPos( E->Message.c_str(), "Empty row cannot be inserted" ) )
   {
      if ( StrPos( E->Message.c_str(), "SomeField" ) )
      {
         ShowMessage( "Field 'SomeField' must have a value" );
         return;
      }
      if ( StrPos( E->Message.c_str(), "OtherField" ) )
      {
         // ... etc ...
      }
      ShowMessage( "Record must not be empty!\n\n" + E->Message );
      return;
   }
   ShowMessage( "Unknown Error.\n\n" + E->Message );
}
