如何从文件DML获取exp_full.dmp声明？

您需要一个数据泵转储文件才能执行此操作，然后您可以执行以下操作：

//WRONG
- (void)keyDown:(NSEvent *)event
{
    //unichar character = 0;
    //if ([event type] == NSEventTypeKeyDown) {
    //    if ([[event charactersIgnoringModifiers] length] == 1) {
    //        character = [[event characters] characterAtIndex:0];
    //    }
    //}

    switch (character) {
        //THIS IS WRONG correct is to implement interpretKeyEvents+moveRight 
        //case NSRightArrowFunctionKey:
        //    [self moveSelectedIndexRight];
        //    break;
        //THIS IS WRONG correct is to implement interpretKeyEvents+ moveLeft 
        //case NSLeftArrowFunctionKey:
        //    [self moveSelectedIndexLeft];
        //    break;
        //THIS IS WRONG correct is to implement interpretKeyEvents+ moveLeft 
        //case NSCarriageReturnCharacter:
        //    [self dismissWithCurrentlySelectedToken];
        //    break;
        default:
            [self interpretKeyEvents:@[event]];
            [super keyDown:event]
            break;
    }
}

//CORRECT
- (void)keyDown:(NSEvent *)event
{
   [self interpretKeyEvents:@[event]];
   [super keyDown:event];
}

`/* Catch the commands interpreted by interpretKeyEvents:. Normally, if we don't implement (or any other view in the hierarchy implements) the selector, the system beeps. Menu navigation generally doesn't beep, so stop doCommandBySelector: from calling up t`he hierarchy just to stop the beep.
*/
- (void)doCommandBySelector:(SEL)selector {
    if (   selector == @selector(moveRight:)
        || selector == @selector(moveLeft:)
        || selector == @selector(cancelOperation:)
        || selector == @selector(insertNewline:) )
    {
        [super doCommandBySelector:selector];
    }

    // do nothing, let the menu handle it (see call to super in -keyDown:)
    // But don't call super to prevent the system beep
}
- (void)cancelOperation:(id)sender
{
    //do your escape stuff
}

- (void)insertNewline:(id)sender
{
    //do your enter stuff
}

- (void)moveRight:(nullable id)sender
{
    [self moveSelectedIndexRight];
}

- (void)moveLeft:(nullable id)sender
{
    [self moveSelectedIndexLeft];
}

然后你有了myfile.sql中所有对象的创建脚本。
