<select id="selectCount" parameterType="java.util.Map" resultMap="java.lang.Integer"> SELECT COUNT(m.id) COUNT FROM Monitorevent m LEFT JOIN functionalci f ON m.functionCi_id = f.id LEFT JOIN organization o ON m.org_id = o.id WHERE 1 = 1 <if test="name!=null and name!=''"> AND f.name LIKE CONCAT('%',#{name},'%') </if> </select>正确如下：
<select id="selectCount" parameterType="java.util.Map" resultType="java.lang.Integer"> SELECT COUNT(m.id) COUNT FROM Monitorevent m LEFT JOIN functionalci f ON m.functionCi_id = f.id LEFT JOIN organization o ON m.org_id = o.id WHERE 1 = 1 <if test="name!=null and name!=''"> AND f.name LIKE CONCAT('%',#{name},'%') </if> </select>
