insert into T1 select 5, 'E'
create table T2(ModuleID int, UserID int)
insert into T2 select 1, 1
insert into T2 select 2, 1
insert into T2 select 3, 1
insert into T2
select b.ModuleID,a.id
from (select * from T1 where ID>3) as a inner join (select * from T2 where UserID=1) as b on 1=1
select * from T2
drop table T1,T2
/*
--结果
ModuleID UserID
