select into from 和 insert into select都是用来复制表，两者的主要区别为： select into from 要求目标表不存在，因为在插入时会自动创建。insert into select from 要求目标表存在
INSERT INTO SELECT语句：
语句形式为：
Insert into Table2(field1,field2,...) select value1,value2,... from Table1
--1.创建测试表
create TABLE Table1
(
a varchar(10),
b varchar(10),
c varchar(10),
CONSTRAINT [PK_Table1] PRIMARY KEY CLUSTERED
(
a ASC
)
) ON [PRIMARY]
create TABLE Table2
(
a varchar(10),
c varchar(10),
d int,
CONSTRAINT [PK_Table2] PRIMARY KEY CLUSTERED
(
a ASC
)
) ON [PRIMARY]
GO
--2.创建测试数据
Insert into Table1 values('赵','asds','')
Insert into Table1 values('钱','asds','')
Insert into Table1 values('孙','asds','')
Insert into Table1 values('李','asds',null)
GO
select * from Table2
--3.INSERT INTO SELECT语句复制表数据
Insert into Table2(a, c, d) select a,c,5 from Table1
GO
--4.显示更新后的结果
select * from Table2
GO
--5.删除测试表
drop TABLE Table1
drop TABLE Table2
正确的形式：
INSERT INTO AC02_WYL
(AAZ159, BAE001, AAB001, AAC001, AAC049)
SELECT A.AAZ159, A.BAE001, A.AAB001, A.AAC001, 201411
FROM AC02 A
WHERE AAB001 = 511500000296;
