Mybatis中模糊查询的各种写法
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
// 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
SELECT * FROM TABLENAME WHERE LOWER(SUBSYSTEM) LIKE '%' || LOWER('jz') || '%'
