标签:username cat res user 试验 name 模糊查询 concat type
这个网站中有很多方法。https://code.google.com/p/mybatis/issues/detail?id=85
自己试验了如下的方法。
1. 参数中直接加入%%
param.setUsername("%CD%");
param.setPassword("%11%");
<select id="selectPersons" resultType="person" parameterType="person">
select id,sex,age,username,password from person where true
<if test="username!=null"> AND username LIKE #{username}</if>
<if test="password!=null">AND password LIKE #{password}</if>
</select>
2. bind标签
<select id="selectPersons" resultType="person" parameterType="person">
<bind name="pattern" value="‘%‘ + _parameter.username + ‘%‘" />
select id,sex,age,username,password
from person
where username LIKE #{pattern}
</select>
3. CONCAT
where username LIKE concat(concat(‘%‘,#{username}),‘%‘)标签:username cat res user 试验 name 模糊查询 concat type
