SQL Server 开发之 复制表数据的SQL脚本生成器 使用SQL Server 2000自带的“生成SQL脚本”工具,可以生成创建表、视图、存储过程等的SQL脚本。那么,能否将表中的数据也生成为SQL脚本,在查询分析器中执行这些脚本后自动将数据导入到SQL Server中呢?答案是肯定的。 下面的存储过程是一位高人写的,这位高人的姓氏已无人知晓,但SQL Server社区中偶尔还可看到此不朽之作。 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' 调用时 exec OutputData 'myuser' 其中myUser中当前数据库中存在的表
