此SP在“＆gt;”附近出现错误“语法错误。”

我必须这样做，如果@FROM_DATE和@TO_DATE两个空白然后在语句AND I.ACTIVE = 1之后没有条件应该添加。如果@FROM_DATE不是空白且@TO_DATE是空白那么一个条件应该像这样添加所有场景。如何解决这个问题？

涉及CASE的谓词未正确形成：

AND CASE
      WHEN ... THEN ...
      WHEN ... THEN ...
    END -- missing a condition here

要解决此问题，请按照以下方式重新编写CASE语句：

AND
CASE          
     WHEN (isnull(@FROM_DATE,'')<>'' and ISNULL(@TO_DATE,'')='') and  Convert(date,A.order_date) >=CONVERT(datetime,@FROM_DATE,105) THEN 1
     WHEN isnull(@FROM_DATE,'')='' and ISNULL(@TO_DATE,'')<>'' and Convert(date,A.order_date)<=CONVERT(datetime,@TO_DATE,105) THEN 1
     WHEN isnull(@FROM_DATE,'')<>'' and ISNULL(@TO_DATE,'')<>'' and Convert(date,A.order_date)<=CONVERT(datetime,@TO_DATE,105) and CONVERT(Date,A.ORDER_DATE)>=CONVERT(datetime,@FROM_DATE ,105)) THEN 1
     ELSE 0
END = 1

Case语句中的多个when语句
