原生寫法
eg：
select * from user where username like '%${value}%'注意：
${value}里面必須要寫value，不然會報錯
oracle數據庫：
SELECT * FROM user WHERE name like CONCAT('%',#{name},'%') 或 :
SELECT * FROM user WHERE name like '%'||#{name}||'%' SQLServer數據庫：
SELECT * FROM user WHERE name like '%'+#{name}+'%' mysql數據庫：
SELECT * FROM user WHERE name like CONCAT('%',#{name},'%') DB2數據庫：
SELECT * FROM user WHERE name like CONCAT('%',#{name},'%') 或
SELECT * FROM user WHERE name like '%'||#{name}||'%'
