SQL SERVER里表里的数据导出成为insert into操作方法
2011/7/29 13:51:13

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' pdf
return
end
set   @objectname=rtrim(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pdftable
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'
