所有从PHP中的ms访问数据库中检索数据

问题描述 投票:0回答:1

使用odbc驱动程序从php中的ms访问数据库2007中检索数据。使用查询检索所有数据,但只获取一条记录检索其他数据,而不检索。

下面查询三条记录,但只检索一条数据。哪个问题下面的代码在php?如何从这段代码中获取所有数据使用什么改变呢?

 <?PHP

    include 'Connection2.php';



    $sql = "select FYearID,Description,FromDate,ToDate  from mstFinancialyear";


    $stmt = odbc_exec($conn, $sql);
    //print_r($stmt);
    $rs = odbc_exec($conn, "SELECT Count(*) AS counter from mstFinancialyear");

    //print_r($stmt);

    $arr = odbc_fetch_array($rs);
    $arr1 = $arr['counter'];
    $result = array(); 

    //print_r($arr);


     if (!empty($stmt)) {

            // check for empty result
            if ($arr1 > 0) {
    // print_r($stmt);

                $stmt1 = odbc_fetch_array($stmt);




               $year = array();
                $year['FYearID'] = $stmt1['FYearID'];
                $year['Description'] = $stmt1['Description'];
                $year['FromDate'] = $stmt1['FromDate'];
                $year['ToDate'] = $stmt1['ToDate'];


                // success
                $result["success"] = 1;

                // user node
                $result["year"] = array();


                array_push($result["year"], $year); 

                echo json_encode($result);

                //return true;

            } else {
                // no product found
                $result["success"] = 0;
                $result["message"] = "No product found";




                echo json_encode($result);


            }


            odbc_close($conn); //Close the connnection first
    }

    ?>

您只返回JSON数据中的单个记录,因为您没有遍历记录集。最初我误读了你在相同的记录集上调用了两次odbc_fetch_array,但经过仔细检查,看到一个查询被暗示使用,据我所知,看看是否有任何可能从主查询返回的记录。下面重写的代码尚未经过测试 - 我没有办法这样做 - 并且只有一个查询,但确实尝试迭代循环。

如果由于某种原因需要记录的数量,我在主查询中包含count作为子查询 - 但我不认为它是。

<?php

    include 'Connection2.php';

    $result=array();

    $sql = "select 
            ( select count(*) from `mstFinancialyear` ) as `counter`,
            `FYearID`, 
            `Description`,
            `FromDate`,
            `ToDate` 
        from 
        `mstFinancialyear`";

    $stmt = odbc_exec( $conn, $sql );

    $rows = odbc_num_rows( $conn );
    /* odbc_num_rows() after a SELECT will return -1 with many drivers!! */


    /* assume success as `odbc_num_rows` cannot be relied upon */
    if( !empty( $stmt ) ) {

        $result["success"] = $rows > 0 ? 1 : 0;
        $result["year"] = array();

        /* loop through the recordset, add new record to `$result` for each row/year */
        while( $row=odbc_fetch_array( $stmt ) ){ 

            $year = array();
            $year['FYearID'] = $row['FYearID'];
            $year['Description'] = $row['Description'];
            $year['FromDate'] = $row['FromDate'];
            $year['ToDate'] = $row['ToDate'];

            $result["year"][] = $year;

        }
        odbc_close( $conn );
    }

    $json=json_encode( $result );
    echo $json;
?>
