I.下面是用sql编程一次性插入多条语句的完整实例:
declare @a int, @b int
set @a=1
set @b=20
while @a<=20
begin
insert into testtb(tid,tvalue)values(@a,@b)
set @a=@a+1
set @b=@b-1
end
select * from testtb
go
set @a=1
set @b=20
while @a<=20
begin
insert into testtb(tid,tvalue)values(@a,@b)
set @a=@a+1
set @b=@b-1
end
select * from testtb
go
II.使用insert into 表名(字段列表) select 值列表 union all select 值列表的语句格式:
insert into testtb(tid,tvalue)
select 94,100 Union all
select 72,12
go
select 94,100 Union all
select 72,12
go
III.
1》.从存在的表复制数据到新表(与旧表表结构相同的表):
create table newtb(nid int,nvalue int ) go
INSERT INTO newtb (nid, nvalue) SELECT tid,tvalue FROM testtb
INSERT INTO newtb (nid, nvalue) SELECT tid,tvalue FROM testtb
SELECT tid,tvalue into newtb FROM testtb
