<update id="automaticRelease2">
replace into zxzq_drawcash (memberid, securitiesnum) select h.memberid ,

</update>
<update id="automaticRelease3">
update zxzq_holding h, zxzq_record r set h.securitiesnum =
if( r.securities > TRUNCATE(h.securitiesnum * 0.999,2) , r.securities,  TRUNCATE(h.securitiesnum * 0.999,2)) where r.securitiesid = h.securitiesid
and r.price = r.realprice
</update>

作为定时器的sql代码，通过spring定时任务来完成。

<task:annotation-driven />

<task:scheduled-tasks>
<task:scheduled ref="securitiesController" method="automaticRelease" cron="0 0 0 ? * MON-FRI"/>
</task:scheduled-tasks>

还需要在

securitiesController的

automaticRelease

@Scheduled
