SQL Server查询错误：“缺少或不完整的select语句”

Question

SELECT 
    Id, Product, 
    [fare] = CASE WHEN @date BETWEEN s1from AND s1to THEN s1rate ELSE fare 
FROM Table1

错误：

  

缺少或不完整的选择陈述

Answer 1

你有没有忘记CASE声明结尾处的END关键字？

IE中。

SELECT 
    Id, Product, 
    [fare] = CASE WHEN @date BETWEEN s1from AND s1to THEN s1rate ELSE fare END
FROM Table1

Answer 2

尝试

SELECT Id, Product, [fare] =
CASE @date
WHEN BETWEEN s1from AND s1to THEN s1rate 
ELSE fare
END
FROM Table1

Answer 3

查询可能是这样的，

Select Id, Product, (case when @date between s1from and s1to then s1rate else fare end)as fare from  Table1.

试试这个。
