SELECT INTO 和“未声明的变量"；错误

SELECT INTO and quot;Undeclared variablequot; error(SELECT INTO 和“未声明的变量；错误)

问题描述

当我尝试执行以下查询时:

When I try to execute following query:

SELECT id_subscriber
  INTO newsletter_to_send
  FROM subscribers 

我收到一个错误:

#1327 - 未声明的变量:newsletter_to_send

该查询有什么问题?

推荐答案

INSERT ... SELECT

INSERT INTO newsletter_to_send
SELECT id_subscriber FROM subscribers 

PS:你确定你不需要 WHERE 子句吗?

PS: are you sure you don't need in WHERE clause?
