工作中用到，寫三種用法吧，第四種為大小寫匹配查詢
?
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. 大小寫匹配查詢
?? SELECT *? FROM TABLENAME? WHERE UPPER(SUBSYSTEM) LIKE '%' || UPPER('jz') || '%'
?? 或者?
?? SELECT *?? FROM TABLENAME? WHERE LOWER(SUBSYSTEM) LIKE '%' || LOWER('jz') || '%'
)
