原生写法
eg:
select * from user where username like '%${value}%'
注意:
${value}里面必须要写value,不然会报错
oracle数据库:
SELECT * FROM user WHERE name like CONCAT('%',#{name},'%')
或 :
SELECT * FROM user WHERE name like '%'||#{name}||'%'
SQLServer数据库:
SELECT * FROM user WHERE name like '%'+#{name}+'%'
mysql数据库:
SELECT * FROM user WHERE name like CONCAT('%',#{name},'%')
DB2数据库:
SELECT * FROM user WHERE name like CONCAT('%',#{name},'%')
或
SELECT * FROM user WHERE name like '%'||#{name}||'%'
