我很难找出为什么我的 t-sql 字符串会出现错误消息，如您所见，我创建了这个 sql 以从其他表中提取信息以创建容量表，但是有些不对劲，我不能弄清楚它是什么。你能帮我吗。提前致谢。

错误信息：

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

SQL脚本：

DECLARE @PitchType_Skey INT
DECLARE @Site_Skey INT

SET @Capacity = 0

您正在插入Capacity2表中，但没有指定将哪些值放入哪些列中。我猜这是问题的原因，它试图将您的其他整数值之一放入您的开始日期列。

您还没有发布您的架构，所以我只能猜测您的列名，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 ...

这样一来，您想将哪个值插入到哪一列中就没有歧义了。
