SQL批量插入、修改

1. 批量插入

insert into table_A  ( ORDER_CODE, PAYMENT_CODE) values
<foreach item="item" index="index" collection="list" separator=",">
(#{item.ORDER_CODE},if(#{item.PAYMENT_CODE}='',NULL,#{item.PAYMENT_CODE}))

 

2.批量更新

update table_A set
PDH_CNT=
<foreach collection="list" item="item" index="index" separator=" " open="case EFH_SN" close="end">
when #{item.efhSn,jdbcType=VARCHAR} then #{item.pdhCnt,jdbcType=INTEGER}
</foreach>
,DUE_DT=
<foreach collection="list" item="item" index="index" separator=" " open="case EFH_SN" close="end">
when #{item.efhSn,jdbcType=VARCHAR} then #{item.dueDt,jdbcType=TIMESTAMP}
</foreach>
where del_flg=0 and EFH_SN in
<foreach collection="list" index="index" item="item" separator="," open="(" close=")">
#{item.efhSn,jdbcType=VARCHAR}
</foreach>

 

3. table_A 數據導入table_B

INSERT INTO table_B (COMPANY_CODE,ORDER_CODE,PAYMENT_CODE,USER_CODE)

　　 SELECT COMPANY_CODE,ORDER_CODE,PAYMENT_CODE,USER_CODE FROM table_A 

4.清空表table_A 

truncate table table_A
