spring batch中MyBatisPagingItemReader分页使用介绍

Posted 2021-01-01 ppjj

假如是mysql的话，SQL语句

select * from 
(
SELECT so.* FROM t_tm_sales_order so 
where so.last_modified_time >= to_timestamp(‘2015-05-05‘,‘yyyy-mm-dd hh24:mi:ss‘) 
order by so.id limit #{_pagesize} OFFSET #{_skiprows}  
) temp_a inner join t_tm_sales_order_line sol on temp_a.id=sol.so_id

假如是oracle的话，SQL语句

select t2.* from
(select t1.*,rownum rn from
(select * from a) t1 where rownum<= (#{_pagesize} + #{_skiprows})) t2 where t2.rn > #{_skiprows}
