代码如下

复制代码

Create PROCEDURE dbo.UspOutputData
@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??ο笫欠翊嬖?nbsp;
begin
print 'The object not exists'
return
end
set @objectname=object_name(@objectId)

if @objectname is null or charindex(@objectname,@tablename)=0 --此判断不严密
begin
print 'object not in current database'
return
end

if OBJECTPROPERTY(@objectId,'IsTable') 1 -- 判??ο笫欠袷?able
begin
print 'The object is not table'
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'

declare syscolumns_cursor cursor
for select c.name,c.xtype from syscolumns c
where c.id=@objectid
order by c.colid
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'

GO

执行方法是: exec UspOutputData 你的表名
得到导出数据的语句，但image,text,ntext,sql_variant 列不出现在语句，以后改进。
