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'
