Question

我很难找到为什么我的t-sql字符串会出现错误消息，因为你可以看到我创建了这个sql从其他表中提取信息来创建容量表，但是有些东西不对我无法弄清楚它是什么。你能帮我吗。提前谢谢。

错误讯息：

Msg 206, Level 16, State 2, Line 32
Operand type clash: int is incompatible with date

SQL脚本：

DECLARE @PitchType_Skey INT

Answer 1

您正在插入Capacity2表，而没有指定将哪些值放入哪些列以放入每个值。我猜这是导致问题的原因，并且它试图将您的其他整数值放入开始日期列。

您尚未发布架构，因此我只能猜测您的列名称，但我建议您将脚本的插入部分更改为：

INSERT INTO Capacity2 (StartDate, EndDate, Capacity, PitchTypeKey, Site_SKey)
SELECT 
   CASE 
     WHEN ...

这样就没有关于要将哪个值插入哪个列的歧义。
