访问语法错误

Question

我尝试在Access数据库中加入多个表。我继续收到＆＃34;语法错误＆＃34;。如果您需要更多信息，请与我们联系。我发布了下面的架构。

SELECT VicDescriptions.VID, 
       VicDescriptions.Make, 
       VicDescriptions.Vic_Year, 
       VicDescriptions.OptionTable, 
       VacDescriptions.Accessory, 
       VacValues.Value, 
       VacValues.ValueType
FROM  VicDescriptions 
       INNER JOIN VacValues 
         ON ( VicDescriptions.Vic_Make = VacValues.Vic_Make 
              AND VicDescriptions.Vic_Year = VacValues.Vic_Year )
     INNER JOIN VacDescriptions
         ON ( VacDescriptions.Period = VacValues.Period
               AND VacDescriptions.VAC = VacValues.VAC);

DATABASE SCHEMA

Answer 1

MS Access就像连接的括号一样：

- (void)didBecomeFirstResponder:(NSNotification *)note
{
    if ([note.object isKindOfClass:[NSView class]] && [[(NSView *)note.object superview] superview] == self) {
        // You just became the first responder
    }
}
