Mybatis各种模糊查询

模糊查询:

工作中用到,写三种用法吧,第四种为大小写匹配查询

 

1. sql中字符串拼接

   SELECT * FROM tableName WHERE name LIKE CONCAT(CONCAT('%', #{text}), '%');

 

2. 使用 ${...} 代替 #{...}

   SELECT * FROM tableName WHERE name LIKE '%${text}%'; 

 

3. 程序中拼接

   Java

  // or String searchText = "%" + text + "%";

   String searchText = new StringBuilder("%").append(text).append("%").toString();

   parameterMap.put("text", searchText);

 

  SqlMap.xml

   SELECT * FROM tableName WHERE name LIKE #{text};

 

4. 大小写匹配查询

 

SELECT * FROM TABLENAME WHERE UPPER(SUBSYSTEM) LIKE '%' || UPPER('jz') || '%'
--或者是
SELECT * FROM TABLENAME WHERE LOWER(SUBSYSTEM) LIKE '%' || LOWER('jz') || '%'
