SQL Server 脚本 SQL Go C

使用SQL Server 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，网上收集资料如下：

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。
