目标是批量更新目标表部分字段的数据 操作内容: 1.创建临时表
drop table if exists tempTableXXX create table tempTableXXX ( TEMP_ID int not null, BM varchar(14) )
2.把数据存入临时表 3.把临时数据中的数据存入目标表
update targetTableXXX ,(select * from tempTableXXX ) b set BM=b.BM where b.TEMP_ID=targetTableXXX.ID
4.删除临时表
drop table if exists tempTableXXX
出现问题:
The target table of the UPDATE is not updatable
原因是update的字段在targetTableXXX中不存在=.=
