MyBatis Oracle与MySQL分页

Oracle、MySQL分页实例

• SQL执行代码

ORACLE:
SELECT * FROM (
	SELECT ROWNUM AS NUMROW, Z.* from (
		select * from CHANNEL T where 1=1 and T.ID = 1 ORDER BY T.ID desc 
	) Z  where rownum<=10
) WHERE NUMROW >= 1 


MySQL:获取(0 ,10]，10表示向后获取10条数据。
select * from fm_sell T 
where 1=1 and T.SERIAL_NUM = '20141124' ORDER BY T.ID desc LIMIT 0, 10

 

• Mybatis中分页应用与优化

Oracle：

	
		1=1
		
			AND T.ID = #{id,jdbcType=BIGINT}
		
		...
	



	ORDER BY T.ID desc 



	SELECT * FROM (SELECT ROWNUM AS NUMROW, Z.* from (



	= #{pageFristItem} ]]>



	select count(1) from CHANNEL T
	
	



	
	select
	
	from CHANNEL T
	
	
	

 

MySQL：

	
	
	...



	T.ID, T.SERIAL_NUM, T.STOCK_ID, T.GMT_CREATE, T.GMT_MODIFY



	
		1=1
		
			AND T.SERIAL_NUM = #{serialNum,jdbcType=VARCHAR}
		
		...
	




	LIMIT #{pageIndex}, #{pageSize}



	ORDER BY T.ID desc 




	SELECT 
	FROM fm_sell T
	
	
	




	SELECT COUNT(1) FROM fm_sell T
