SQL 向表追加数据行 mySQL java

好久没有不见了,困扰很久的问题在今天终于解决了,以前一直用
select * into? table1 from? table2

假如需要将table1 追加数据,却没有办法,只能用中间table3

select * into table3
from
(
select * from table1
union all
select * from table2
) data

--向表追加数据sql 语句
select * into #120 from
(
select 2 as source_type,D56.rkey,69 as fac from XXXXX d56
LEFT JOIN
(select * from data9287 where source_type =2) D9287 ON D9287.SOURCE_PTR=D56.RKEY
?where?? D9287.RKEY IS NULL AND tdate>='2013-09-01'
)AA
go
insert into data9287(source_type,source_ptr,plant_ptr)select source_type,rkey,fac from #120
go
Drop table #120


select * into #121 from
(
select 1 as source_type,D48.rkey,69 as fac from XXXXX D48
LEFT JOIN
(select * from data9287 where source_type =1) D9287 ON D9287.SOURCE_PTR=D48.RKEY
?where?? D9287.RKEY IS NULL AND tdate>='2013-09-01'
)AA
go
insert into data9287(source_type,source_ptr,plant_ptr)select source_type,rkey,fac from #121
