Question

我有一个完整的查询，可以在SSRS中正确显示，但是，当我添加这个where子句时，我收到错误

数据集＆＃39; dataset1＆＃39;的查询执行失败。（rsErrorExecutingCommand）

这是我添加的WHERE子句：

where 
    (itemNo = @ItemNo or @ItemNo is NULL) 
    and (JobNo in (@JobNo) or @JobNo is NULL) 
    and (customerNo = @CustomerNo or @CustomerNo is NULL) 
    and (LotNo in (@LotNo) or @LotNo is NULL)
    and (Station = @Station or @Station is NULL) 
    and ((DateTimeStamp between @startDate and  @endDate) or (@startDate is null and @endDate is Null))

你们有任何想法我在这里做了什么语法错误吗？

我添加String后代码正常工作。下面是我做的，它的工作正常。这是因为，我注意到值不是Null，而是空字符串，这就是我的代码不起作用的原因。

(itemNo = @ItemNo or @ItemNo is NULL or @ItemNo = '') 
and(JobNo = @JobNo or @JobNo is NULL or @JobNo = '')
and(customerNo = @CustomerNo or @CustomerNo is NULL or @CustomerNo = '') 
and (LotNo = @LotNo or @LotNo is Null or @LotNo = '')
and (Station = @Station or @Station is NULL or Station = '') 
and ((DateTimeStamp between @startDate and @endDate) or (@startDate is null and @endDate is Null))

添加where子句后，SSRS SQL查询显示错误
