select-asp文件转换php实现，主要是SQLSERVER里的存储过程转换成mysql语句写不出来！

=================存储过程=======================
ALTER PROCEDURE [dbo].[CreatUser]
-- Add the parameters for the stored procedure here
@Username varchar(50),
@userPassword varchar(50),
@QQID varchar(11),
@nResult int output
AS
BEGIN
declare @Qid int
set @Qid=null
select @Qid=id from [user] where qusername=@Username
if @Qid is not null
begin
set @nResult=-1
Goto theEnd
end
INSERT INTO [qqmsg].[dbo].user
select @QQID,@Username,@userPassword
set @nResult=0

theEnd:
SET NOCOUNT ON;
END

ALTER PROCEDURE [dbo].[insertFriendGroup]
-- Add the parameters for the stored procedure here
@GroupName varchar(50),
@Ownerqid varchar(11),
@Groupid int output
AS
BEGIN
declare @Qid int
set @Qid=null
select @Qid=id from [user] where qid=@Ownerqid
if @Qid is null
set @Groupid=-1
else
begin

select @Qid=id from [qqmsg].[dbo].[FriendQIDFolder] where [ownerQid]=@Ownerqid and [FolderName]=@GroupName

begin
INSERT INTO [qqmsg].[dbo].FriendQIDFolder
select @Ownerqid,@GroupName
select top 1 @Groupid=id from [FriendQIDFolder] where
[ownerQid]=@Ownerqid and [FolderName]=@GroupName
end
else
set @Groupid=-2

endSET NOCOUNT ON;
