如何在SQLite数据库中插入datetime值?
问题描述:
我正在尝试将一个datetime值插入 SQLite 数据库。这似乎是成功的,但是当我尝试检索该值时,会出现一个错误:
I am trying to insert a datetime value into a SQLite database. It seems to be sucsessful but when I try to retrieve the value there is an error:
<无法读取数据>
<Unable to read data>
SQL语句是:
create table myTable (name varchar(25), myDate DATETIME)
insert into myTable (name,mydate) Values ('fred','jan 1 2009 13:22:15')
答
您需要的格式是:
'2007-01-01 10:00:00'
ie yyyy-MM-dd HH:mm:ss
i.e. yyyy-MM-dd HH:mm:ss
然而,如果可能,使用参数化查询可以免除您担心格式化细节。
If possible, however, use a parameterised query as this frees you from worrying about the formatting details.
