最近公司换成sqlserver数据库；经常需要把表数据转化成插入语句，可用如下语句

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'

exec OutputData 'TA_TPREPRODUCT'
