SQL

Question

我需要做一个列的子字符串，但在做 select 时还要提取所有列。以下是我尝试使用的代码，但它无法正常运行：

SELECT SUBSTRING(column_c, 1, 11) AS dateMoved, *
                FROM prostock_movement_header 
                WHERE column_a = '74' 
                AND column_b = '1372' 
                AND dateMoved = '2019-02-23'

如何在同一语句中执行 SELECT * 和 SUBSTRING() AS ALIAS，以便检索所有列以及 ALIAS 列。

或者是从 table 按名称手动 select 每隔一列的唯一方法？

谢谢

只需更改选择的顺序

SELECT *,SUBSTRING(column_c, 1, 11) AS dateMoved
                FROM prostock_movement_header 
                WHERE column_a = '74' 
                AND column_b = '1372' 
                AND SUBSTRING(column_c, 1, 11) = '2019-02-23'

SQL - 子字符串和 select * 同时

SQL - Substring and select * at the same time
