Question

我正在尝试在下面的存储过程中创建一个case语句。我希望@OHDept执行以下操作：

如果部门= 15，则显示16

我尝试的所有内容都会给我一些错误，例如＆＃34;在预期条件的比赛中指定的非布尔类型的表达式，接近＆＃34;否则＆＃34;。

我知道我做错了什么，但我不确定是什么。有人能帮我吗？谢谢！

(@JCCo bCompany,  @BeginContract bContract ='', @EndContract bContract= 'zzzzzzzzz', @ThroughMth bDate,@BegMth bDate,@BegDept bDept='', @EndDept bDept='zzzzzzzzzz', @Status char(1)='A', @BegMthClosed bDate, @EndMthClosed bDate)

Answer 1

我没有看到您发布的代码@OHDept中的任何值被赋予了任何值。

无论在何处为其分配值，您都可以使用以下内容来遵循该语句：

set @OHDept = case when @OHDept = '15' then '16' else @OHDept end;

Answer 2

您似乎试图以类似于您在程序语言中使用case的方式使用if。在SQL中，case是一个表达式，在流中计算为值而不是分支。

将值15转换为16而将其他值保持不变的表达式为：

case where @OHDept = '15' then '16' else @OhDept end

听起来这个表达式属于select子句，因为你提到过它。

我也认为布尔逻辑正在绊倒你。您可以通过这种方式轻松压缩查询顶部的大量内容。由于and的优先级高于or，因此您不必严格需要括号。

(
    @Status in ('O', 'S') and ContractStatus in (1, 2, 3))
    and MonthClosed > @ThroughMth 
)
or
(
    @Status = 'C' and ContractStatus = 3
    and MonthClosed between @BegMthClosed and @EndMthClosed 
)
or
(
    @Status = 'A' and ContractStatus <> 0
)
