mybatis mapper.xml資料庫對映生成java實體，增刪改查sql語句
1.問題描述：使用mybatis生成mapper.xml檔案的時候經常遇到資料庫表字段很多，寫mapper.xml檔案時轉化成java實體很麻煩，寫增刪改查的sql時也要做
很多重複的工作。程式設計師就想一勞永逸，我拼接了幾個sql可以簡化，方便生成資料庫對映和java實體。（待解決問題，沒有JDBCTYPE，需要再建立一個對映java型別和資料庫欄位型別的關係表）
2.解決：
先來一個表結構（欄位很多，要是一個一個寫，早煩啦煩啦，死啦死啦，怎麼破？）

2.1 mysql版本(後面有oracle版本）
先建立一個拼sql的函式（做了兩件事,把下劃線後面的字母大寫，去除下劃線）
CREATE
FUNCTION fun_yxl_rep(str varchar(128))
RETURNS varchar(128) CHARSET utf8
BEGIN
DECLARE len,
i int;
DECLARE ch char;
DECLARE s1,s2 varchar(128);
SET i = 1;
SELECT
LENGTH(str) INTO len;
WHILE (i <= len) DO
SET ch = SUBSTRING(str, i, 1);
IF (ch = '_' and (i+1) <= len) THEN
set s1 = SUBSTRING(str, 1, i);
set s2 = SUBSTRING(str, i+2, len - i);
SET str = CONCAT(s1,UPPER(SUBSTRING(str, i+1, 1)),s2);
END IF;
SET i = i + 1;
END WHILE;
RETURN REPLACE(str,'_','');
END
2.2使用
2.2.1.生成表的列升序排列（注意修改表名和schema就可以用了）
select CONCAT('t.',COLUMN_NAME,',') from information_schema.COLUMNS where
table_name = 't_ltl_order' and table_schema = 'oms'order by COLUMN_NAME;
