Question

我有一个场景，我的多个Select / Update / Select语句最终在我的基于网络的应用中显示结果集。我不知道如何处理这种情况。下面是相同的代码。有人可以建议我如何实现这个目标？目前，它在某处失败并且在网页上没有显示任何内容。甚至没有错误。

   <?php

                    }

管理以解决此问题。

$query="BEGIN TRAN;
QUERY1: SELECT INTO #TEMP TABLE;
QUERY2: UPDATE #TEMP TABLE;
QUERY3: UPDATE #TEMP TABLE;
QUERY4: UPDATE #TEMP TABLE;
QUERY5: SELECT COLUMN1, COLUMN2,...COLUMN11 from #TEMP TABLE.
COMMIT TRAN;";

上面的代码全部用PHP执行，如下所示：

                    if (($result = sqlsrv_query($ConnectionInfo,$query)) == null) {
                        echo "Died: ";
                            die(print_r(sqlsrv_errors(), true));
                        //die("Something didn't go too smoothly! Try refreshing?");
                        }
                        else
                        {
                            $numRows = sqlsrv_num_rows($result);
                            do {                            
                                while($row = sqlsrv_fetch_array($result))
                                {

                                    echo "<tr class='odd gradeX'>
                                                <td>$row[0]</td>
                                                <td>$row[1]</td>
                                                <td>$row[2]</td>
                                                <td>$row[3]</td>
                                                <td>$row[4]</td>
                                                <td>$row[5]</td>
                                                <td>$row[6]</td>
                                                <td>$row[7]</td>
                                                <td>$row[8]</td>
                                                <td>$row[9]</td>
                                                <td>$row[10]</td>
                                                <td>$row[11]</td>
                                            </tr>";
                                }
                            } while (sqlsrv_next_result($result));
                                echo "</tbody>";
                        }
                    // Close the connection to MSSQL
                    sqlsrv_close($ConnectionInfo);

                    ?>

结果集在网页上呈现正常。
