按住鼠标单击C＃继续鼠标按下并释放模拟

Question

所以我的意思是举例来说，举行LEFT_CLICK，模拟鼠标点击和释放。

我尝试了很多方法，但它告诉我的计算机我没有点击，因此，停止循环。

SELECT LAG(VAL) OVER(PARTITION BY CUSTID ORDER BY ORDERID DESC)/val as lagval
          ,LEAD(VAL) OVER(PARTITION BY CUSTID ORDER BY ORDERID DESC)/val as leadval
          ,(val - LAG(VAL) OVER(PARTITION BY CUSTID ORDER BY ORDERID DESC))/
          (val - LEAD(VAL) OVER(PARTITION BY CUSTID ORDER BY ORDERID DESC)) as pctdiff
    FROM sales.OrderValues;
