在 mysql 中设置日期变量

Question

Why does the following return a MEDIUMTEXT type?

set @entered_date = date "2015-01-01";
select @entered_date;

What would be the correct way to store a date in mysql and then later reference that?

Answer 1

You should probably be using single quotes for MySQL date literals:

set @entered_date = '2015-01-01';

Double quotes indicate database objects. Note that you don't need the ANSI date keyword here.
