所以，我已经在我的一个存储过程中实现了这个。如果他们指定的点数较少，则它可以正常工作，但如果他们有正常点数（不少于）并且它们是例如级别 61 并且总共有 482 个点，那么脚本将尝试在总点数上写入 NULL，我想使它，所以它不会这样做，如果他们对点没问题，那就什么也不做。（就像脚本从未执行过一样）因为如果它们有足够的点那么我们就不必添加它们。

如果我理解正确，您可以修改 ELSE。

更改自：

ELSE @NewPoint = @NewPoint

改成：

ELSE return

这将中止脚本并且不会发生更新。

切换到带有 ELSE 子句的 CASE 语句。无论如何，它更简洁。

我仍然对您的问题感到有些困惑，但这应该可以按我的理解进行。IF考虑移动到单个语句中，而不是所有语句，CASE将值默认为 0。然后添加检查值是否不为 0，以执行某些操作。

DECLARE @Level int
DECLARE @Total int
DECLARE @NewPoint int

SET @Level = 61
SET @Total = 100

SELECT 
  @NewPoint = CASE
                WHEN @Level = 61 AND @Total < 482 THEN 10
                WHEN @Level = 62 AND @Total < 487 THEN 15
                WHEN @Level = 63 AND @Total < 492 THEN 20
                WHEN @Level = 64 AND @Total < 497 THEN 25
                WHEN @Level = 65 AND @Total < 502 THEN 30
                ELSE 0
              END

IF @NewPoint <> 0 
BEGIN
  SELECT 'DO SOMETHING'
END
