为sql server 数据库表数据生成insert 脚本

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 Data

@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=@objectidstatus&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 , from syscolumns c

where =@objectid

order by

--打开游标

and

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

'''''''''+convert(char(16),'+@name+',120)+''''''''' --smalldatetime

then

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。

另外方丈的：
