如题
在查询分析器以“文本显示结果”方法执行
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。
存储过程UspOutputData如下：
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 -- 判斷對象是否存在
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 -- 判斷對象是否是table
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
