MySql选择，需要添加到我的语句中

Question

我有一个声明从数据库中选择活动项目，但我还想让它选择以名称BlueBall开头的项目。

我目前的代码：

$query = "SELECT ShortName FROM product WHERE Active = 1";

Answer 1

SELECT ShortName FROM product WHERE Active = 1 OR ShortName LIKE 'BlueBall%'

Answer 2

SELECT ShortName FROM product WHERE Active = 1 AND ShortName LIKE 'BlueBall%'

Answer 3

您需要使用like这样的条件：

$query = "SELECT ShortName FROM product WHERE Active = 1 AND ShortName like 'BlueBall%'";

Answer 4

SELECT ShortName FROM product WHERE Active = 1 AND ShortName LIKE "BlueBall%"

请参阅：http://dev.mysql.com/doc/refman/5.0/en/pattern-matching.html

Answer 5

只需使用OR运算符为where子句添加名称 这是重写的查询：

$query = "SELECT ShortName FROM product WHERE Active = 1 OR name like 'BlueBall%';

Answer 6

SELECT ShortName FROM product WHERE Active = 1 OR ShortName LIKE 'BlueBall%'

会奏效。  http://w3schools.com/sql/sql_like.asp
