- oracel一次查询多个sequence，批量查询sequence
SELECT SEQ.nextval FROM dual CONNECT BY ROWNUM <= #{batchSize}
- oracel批量插入-先批量获取sequenceId赋值给主键，再批量插入
<insert id="batchSave"> INSERT INTO NOTIFY_BREED(id, notify_id, breed_id) <foreach collection="dataSet" open="(" item="item" separator=" union " index="index" close=")"> SELECT #{item.id}, #{item.notifyId}, #{item.breedId} FROM DUAL </foreach> </insert>
