快速将一个表的数据生成SQL插入语句
将一个表中的数据生成SQL插入语句,方便系统快速初始化,在数据库中执行创建以下过程就可以了。
if exists (select * from sysobjects where id=object_id('GenerateData') and OBJECTPROPERTY(id, 'IsProcedure') =1 ) Drop Procedure GenerateData go CREATE PROCEDURE GenerateData @tablename sysname AS begin declare @column varchar(2000) declare @columndata varchar(2000) declare @sql varchar(8000) 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 '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 -- 判断对象是否是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 into '+@tablename+'('+@column+') values(''as ''--'','+@columndata+','')'' from '+@tablename print '--'+@sql exec(@sql) if @ident is not null print 'SET IDENTITY_INSERT '+@TableName+' OFF' end GO
实例,要将表t_sys_menu中的生成插入语句,就如下执行操作即可:
exec GenerateData 't_sys_menu'
