    sqlsrv_fetch — Makes the next row in a result set available for reading

    説明

    sqlsrv_fetch(resource $stmt, int $row = ?, int $offset = ?): mixed

    Makes the next row in a result set available for reading. Use sqlsrv_get_field() to read the fields of the row.

    パラメータ

    stmt

    A statement resource created by executing sqlsrv_query() or sqlsrv_execute().

    row

    The row to be accessed. This parameter can only be used if the specified statement was prepared with a scrollable cursor. In that case, this parameter can take on one of the following values:

    • SQLSRV_SCROLL_NEXT
    • SQLSRV_SCROLL_PRIOR
    • SQLSRV_SCROLL_FIRST
    • SQLSRV_SCROLL_LAST
    • SQLSRV_SCROLL_ABSOLUTE
    • SQLSRV_SCROLL_RELATIVE

    offset

    Specifies the row to be accessed if the row parameter is set to SQLSRV_SCROLL_ABSOLUTE or SQLSRV_SCROLL_RELATIVE. Note that the first row in a result set has index 0.

    戻り値

    Returns true if the next row of a result set was successfully retrieved, false if an error occurs, and null if there are no more rows in the result set.

    例

    例1 sqlsrv_fetch() example

    The following example demonstrates how to retrieve a row with sqlsrv_fetch() and get the row fields with sqlsrv_get_field().

    <?php
    $serverName     = "serverName\sqlexpress";
    $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
    $conn = sqlsrv_connect( $serverName, $connectionInfo);
    if(     $conn === false ) {
    die(     print_r( sqlsrv_errors(), true));
    }

    $sql = "SELECT Name, Comment
    FROM Table_1
    WHERE ReviewID=1"    ;
    $stmt = sqlsrv_query( $conn, $sql);
    if(     $stmt === false ) {
    die(     print_r( sqlsrv_errors(), true));
    }

    // Make the first (and in this case, only) row of the result set available for reading.
    if( sqlsrv_fetch( $stmt ) === false) {
    die(     print_r( sqlsrv_errors(), true));
    }

    // Get the row fields. Field indices start at 0 and must be retrieved in order.
    // Retrieving row fields by name is not supported by sqlsrv_get_field.
    $name = sqlsrv_get_field( $stmt, 0);
    echo     "$name: ";

    $comment = sqlsrv_get_field( $stmt, 1);
    echo     $comment;
    ?>
