如何為SQL Server表數據生成insert腳本
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 -- 判斷對象是否存在
begin
print @tablename + '對象不存在'
return
end
set @objectname=rtrim(object_name(@objectId))
if @objectname is null or charindex(@objectname,@tablename)=0
begin
print @tablename + '對象不在當前數據庫中'
return
end
if OBJECTPROPERTY(@objectId,'IsTable') < > 1 -- 判斷對象是否是表
begin
print @tablename + '對象不是表'
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'
--定義游標，循環取數據并生成Insert語句
declare syscolumns_cursor cursor for
select c.name,c.xtype from syscolumns c
where c.id=@objectid
order by c.colid
--打開游標
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不需處理，image,text,ntext,sql_variant 暫時不處理
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'
調用時 exec OutputData 'myuser' 其中myUser中當前數據庫中存在的表。
另外方丈的：
