PHP和SQL服务器存储过程的执行

我有一个存储过程，它执行一个登录过程，在不同的条件下返回相同结构的不同值。

这是我的代码:

create PROCEDURE [dbo].[I_SPCheckUserLogin]
 @username nvarchar(50),
 @password varchar(max)
AS
Begin
    declare @incorrect_pass_msg nvarchar(MAX) = N'کاربر گرامی کلمه عبور نادرست است';
    declare @login_success_pass_msg nvarchar(MAX) = N'کاربر گرامی عملیات ورود با موفقیت انجام شد';
    declare @user_not_exists_msg nvarchar(MAX) = N'چنین کاربری یافت نشد';
    declare @lock_user_msg nvarchar(MAX) = N'کاربر گرامی به دلایل امنیتی شما قادر به ورود نمی باشید';
    declare @change_pass_msg nvarchar(MAX) = N'به دلایل امنیتی باید کلمه عبور تغییر یابد';
    declare @error_number int = 0;
    declare @msg nvarchar(100);
    declare @version nvarchar(50);
    declare @rule_lock_login_time int;

    declare @md5_number int;
    select top 1 @md5_number = Value from SplitString(@version,'.') order by Id desc;

                    if(@@ERROR !=0)

                end
            end
            if(@upass != @m_password)
            begin
                declare @tmp table(uattemp_login nvarchar(max));
                update I_Users 
                set AttemptToLogin = AttemptToLogin + 1 
                output inserted.AttemptToLogin into @tmp

                    update I_Users set LockLoginTime = @server_time where Id=@uid
                    if(@@ERROR !=0)
                    begin
                        select 3 error , 'update faild' [message];
                        return;
                    end
                end
                set @error_number = 1;
                set @msg = @incorrect_pass_msg;
                select @error_number error , @msg [message];
                return;
            end
            else
            begin
                if @umust_change_pass = 'true'
                begin
                    set @error_number = 2;
                    set @msg = @change_pass_msg;
                    select @error_number error , @msg [message];
                    return;
                end
                else
                begin
                    if @upass_never_expire = 'false'
                    begin
                        if @server_date> (select [date] from AddDaysToDate_Custom((select dbo.ShamsitoMiladi(@ulast_change_pass_date)),@rule_expire_days))
                        begin
                            set @error_number = 2;
                            set @msg = @change_pass_msg;
                            select @error_number error , @msg [message];
                            return;
                        end
                    end
                    update I_Users 
                    set LastLoginDate = @server_date,
                        LastLoginTime = @server_time,
                        LockLoginTime = null,
                        AttemptToLogin = 0
                    where Id = @uid;
                    if(@@ERROR !=0)
                    begin
                        select 3 error , 'update faild' [message];
                        return;
                    end
                    set @error_number = 0;
                    set @msg = @login_success_pass_msg;
                    select @error_number error , @msg [message];
                    return;
                end
            end
        end
end

问题是当像这样执行这个存储过程时:

$username = trim($username);
$password = trim($password);
$dbconn = new  db_connection();

$select_statement = "execute I_SPCheckUserLogin '{$username}','{$password}'";
echo $select_statement;
$result = $dbconn->do_sql_command($select_statement);
$count = 0;
$row = $dbconn->fetch_array($result);

if ($row['error'] == '0') {
echo '<br/>';
    $this->load->library('session');
    $ci =& get_instance();
    $data = array();
    $data['username'] = $username;
    $data['password'] = $password;
    $data['system_id'] = $system_id;
    $ci->session->set_userdata('user_info', $data);
    redirect('control_panel/index');
} else
    echo $row['message'];

经过大量测试后的问题是，当在这个存储过程中执行更新语句时，存储过程的其余部分没有从PHP执行但是在SQL server管理工作室中执行like charm

对不起我的英语
