sql server 把从一个表查询到的记录插到另一个表
表有标示
sql? server 2k
?
?
set IDENTITY_INSERT copylogtemplates ON
insert into copylogtemplates(ID,RIGHT_VALUE,LOG_TEMPLATE)?
select ID,RIGHT_VALUE,LOG_TEMPLATE from logtemplates
?
sql server 2005有两种方法
insert into copylogtemplates
select * from logtemplates
出现下错误
? 仅当使用了列列表并且 IDENTITY_INSERT 为 ON 时，才能为表'copylogtemplates'中的标识列指定显式值
1：set IDENTITY_INSERT copylogtemplates ON
insert? into (ID,RIGHT_VALUE,LOG_TEMPLATE)? copylogtemplates
select * from logtemplates
?
?
2：set IDENTITY_INSERT copylogtemplates ON
insert? into copylogtemplates (ID,RIGHT_VALUE,LOG_TEMPLATE)?
select * from logtemplates
?
而
sql? server 2k 只能用第二种方法。

????? 2.SELECT INTO FROM语句
??????语句形式为：SELECT vale1, value2 into Table2 from Table1
????? 要求目标表Table2不存在，因为在插入时会自动创建表Table2，并将Table1中指定字段数据复制到Table2中。示例如下：
SELECT INTO FROM创建表并复制表数据
