使用SQL Server 自带的“生成SQL脚本”工具,可以生成创建表、视图、存储过程等的SQL脚本。那么,能否将表中的数据也生成为SQL脚本,在查询分析器中执行这些脚本后自动将数据导入到SQL Server中呢?答案是肯定的,网上收集资料如下:

CREATE PROCEDURE
dbo.OutputData

@tablename sysname

AS

declare @column varchar
(1000)

declare @columndata varchar
(1000)

declare @sql varchar
(4000)

declare @xtype tinyint

declare @name sysname

declare @objectId int

declare @objectname sysname

declare @ident int

set nocount
on

set @objectId=object_id
(@tablename)

if @objectId is
null
--

判断对象是否存在

begin

print
@tablename + '
对象不存在'

return

end

set @objectname=rtrim
(object_name
(@objectId))

if @objectname is null or charindex
(@objectname,@tablename)=0

begin

print
@tablename + '
对象不在当前数据库中'

return

end

if OBJECTPROPERTY
(@objectId,'IsTable') < > 1 --

判断对象是否是表

begin

print
@tablename + '
对象不是表'

return

end

select @ident=status&0x80 from
syscolumns where
id=@objectid and
status&0x80=0x80

if @ident is
not
null

print
'SET IDENTITY_INSERT '+ @TableName + ' ON'

--
定义游标,循环取数据并生成Insert语句

declare syscolumns_cursor cursor for

select
c.name,c.xtype from
syscolumns c

where
c.id=@objectid

order
by
c.colid

--
打开游标

open syscolumns_cursor

set @column=''

set @columndata=''

fetch next
from
syscolumns_cursor into
@name,@xtype

while @@fetch_status <> -1

begin

if
@@fetch_status <> -2

begin

if
@xtype not
in
(189,34,35,99,98) --timestamp

不需处理,image,text,ntext,sql_variant 暂时不处理

begin

set
@column=@column +

case
when
len
(@column)=0 then
''

else
','

end
+ @name

set
@columndata = @columndata +

case
when
len
(@columndata)=0 then
''

else
','','','

end
+

case
when
@xtype in
(167,175) then
'''''''''+'+@name+'+''''''''' --varchar,char

when
@xtype in
(231,239) then
'''N''''''+'+@name+'+''''''''' --nvarchar,nchar

when
@xtype=61 then
'''''''''+convert(char(23),'+@name+',121)+''''''''' --datetime

when
@xtype=58 then
'''''''''+convert(char(16),'+@name+',120)+''''''''' --smalldatetime

when
@xtype=36 then
'''''''''+convert(char(36),'+@name+')+''''''''' --uniqueidentifier

else
@name

end

end

end

fetch
next
from
syscolumns_cursor into
@name,@xtype

end

close syscolumns_cursor

deallocate syscolumns_cursor

set @sql='set nocount
on select ''insert '+@tablename+'('+@column+') values(''as
''--'','+@columndata+','')'' from '+@tablename

print '--'+@sql

exec(@sql)

if @ident is
not
null

print 'SET IDENTITY_INSERT '+@TableName+' OFF'

调用时
exec OutputData 'myuser' 其中myUser中当前数据库中存在的表。
