返回从PHP PDO存储过程中选择*在MS SQL中

Question

对于未来的用户：此问题的底部包含更正的工作代码。

我知道Select *不是最好的，但是在这个例子中，我试图从php调用存储过程并返回ENTIRE结果集，这样我就可以在代码中循环遍历数组。

这是我当前的存储过程：

USE [hanoncs_AskMe]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET NOCOUNT ON;
GO

CREATE PROCEDURE [hanoncs_hanoncs].[CommentsTemp] 
    @QuestionID INT


 AS
 BEGIN
    BEGIN TRANSACTION

        IF Object_id('#viewquestioncomments', 'U') IS NOT NULL DROP TABLE #viewquestioncomments;


        CREATE TABLE #viewquestioncomments 
                     ( 
                                  commentid INT DEFAULT ((0)), 
                                  userid    INT DEFAULT ((0)), 
                                  comment   VARCHAR(max) DEFAULT '', 
                                  datemodified SMALLDATETIME, 
                                  username NVARCHAR(200) DEFAULT '', 
                                  points   INT DEFAULT ((0)) 
                     );


                     INSERT INTO #viewquestioncomments 
                    ( 
                                commentid, 
                                userid, 
                                comment, 
                                datemodified 
                    ) 
        SELECT id, 
               userid, 
               comment, 
               datemodified 
        FROM   hanoncs_askme.hanoncs_hanoncs.comments 
        WHERE  postid=1
        AND    status=1;


        UPDATE #viewquestioncomments 
        SET       username = m.username 
        FROM      #viewquestioncomments c 
        LEFT JOIN hanoncs_securelogin.hanoncs_hanoncs.members m 
        ON        m.id = c.userid;


        UPDATE #viewquestioncomments 
        SET    points = 
               ( 
                      SELECT Count(*) 
                      FROM   hanoncs_askme.hanoncs_hanoncs.commentvotes 
                      WHERE  postid=c.commentid) 
        FROM   #viewquestioncomments c;


        SELECT * 
        FROM   #viewquestioncomments;


        IF @@ERROR != 0
        ROLLBACK TRANSACTION
        ELSE
            COMMIT TRANSACTION
 END

在MS SQL Management Studio中，这将返回我想要的临时表：

EXEC [hanoncs_hanoncs].[CommentsTemp] @QuestionID = 1

我在php中调用它：

    $stmt = $PDO->prepare('EXEC [hanoncs_hanoncs].[CommentsTemp] @QuestionID = ?');
    $stmt->bindParam(1, $QuestionID, PDO::PARAM_INT);
    $stmt->execute();
    $rows6 = $stmt->fetch(PDO::FETCH_BOTH);

我得到的错误是：

PDOException  SQLSTATE[IMSSP]: The active result for the query contains no fields.

编辑：为未来的用户！ 工作代码如下。

存储过程：

USE [hanoncs_AskMe]
GO

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [hanoncs_hanoncs].[CommentsTemp] 
    @QuestionID INT OUTPUT


 AS

 BEGIN
 SET NOCOUNT ON;
    BEGIN TRANSACTION

        IF Object_id('#viewquestioncomments', 'U') IS NOT NULL DROP TABLE #viewquestioncomments;


        CREATE TABLE #viewquestioncomments 
                     ( 
                                  CommentID INT DEFAULT ((0)), 
                                  UserID    INT DEFAULT ((0)), 
                                  Comment   VARCHAR(max) DEFAULT '', 
                                  DateModified SMALLDATETIME, 
                                  UserName NVARCHAR(200) DEFAULT '', 
                                  Points   INT DEFAULT ((0)),
                                  Avatar nvarchar(200) DEFAULT ''
                     );


                     INSERT INTO #viewquestioncomments 
                    ( 
                                commentid, 
                                userid, 
                                comment, 
                                datemodified 
                    ) 
        SELECT id, 
               userid, 
               comment, 
               datemodified 
        FROM   hanoncs_askme.hanoncs_hanoncs.comments 
        WHERE  postid=1
        AND    status=1;


        UPDATE #viewquestioncomments 
        SET       username = m.username , Avatar = m.avatar
        FROM      #viewquestioncomments c 
        LEFT JOIN hanoncs_securelogin.hanoncs_hanoncs.members m 
        ON        m.id = c.userid;


        UPDATE #viewquestioncomments 
        SET    points = 
               ( 
                      SELECT Count(*) 
                      FROM   hanoncs_askme.hanoncs_hanoncs.commentvotes 
                      WHERE  postid=c.commentid) 
        FROM   #viewquestioncomments c;


        SELECT * 
        FROM   #viewquestioncomments;


        IF @@ERROR != 0
        ROLLBACK TRANSACTION
        ELSE
            COMMIT TRANSACTION
 END

PHP：

   $stmt = $PDO->prepare('EXEC [hanoncs_hanoncs].[CommentsTemp] @QuestionID = ?');
   $stmt->bindParam(1, $QuestionID, PDO::PARAM_INT);
   $stmt->execute();
   $rows = $stmt->fetchAll(PDO::FETCH_ASSOC);

尝试添加SET NOCOUNT ON; 在存储过程内（不在您创建过程的位置上方）。

它添加了AS BEGIN 后和前 BEGIN TRANSACTION;

像这样：

CREATE PROCEDURE [hanoncs_hanoncs].[CommentsTemp] 
    @QuestionID INT
 AS  BEGIN
    SET NOCOUNT ON;
    BEGIN TRANSACTION

从它的外观来看，您的结果集将首先包含受影响行的行数，然后包含您想要返回的实际数据。
