SQLServer将数据导出SQL脚本的⽅法SQL Server⾥⾯的⽣成SQL脚本，只会包含数据库及表的字段结构，⽽不会包含表的数据，也就是SQL脚本⾥⾯只有Createdatabase，Create table 这样的语句，没有insert into。那么我们怎么样才能导出数据呢？SQL Server并不包含这个功能，只能靠第三⽅的代码了。⽤这个存储过程可以实现：CREATE PROCEDURE putData

@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=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 , from syscolumns c

where =@objectid

order by

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使⽤⽅法为：在查询分析器以“⽂本显⽰结果”⽅法执⾏

exec UspOutputData 你的表名然后将运⾏后的结果存成.sql，加上⽤SQL Server⽣成的数据库脚本就可以了。缺点和问题：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。
