    설명

    절차식 형식

    mixed maxdb_fetch_fields ( resource $result )

    객체 기반 형식

    mixed maxdb_result::fetch_fields ( void )

    This function serves an identical purpose to the maxdb_fetch_field() function with the single difference that, instead of returning one resource at a time for each field, the columns are returned as an array of resources.

    반환값

    Returns an array of resources which contains field definition information or FALSE if no field information is available.

    Object properties
    Property Description
    name The name of the column
    max_length The maximum width of the field for the result set.
    type The data type used for this field
    decimals The number of decimals used (for integer fields)

    예제

    Example #1 객체 기반 형식

    <?php
    $maxdb     = new maxdb("localhost", "MONA", "RED", "DEMODB");

    /* check connection */
    if (maxdb_connect_errno()) {
           printf("Connect failed: %s\n", maxdb_connect_error());
       exit();
    }

    $query = "SELECT name, cno from hotel.customer ORDER BY cno";

    if (    $result = $maxdb->query($query)) {

           /* Get field information for all columns */
           $finfo = $result->fetch_fields();

       foreach (    $finfo as $val) {
               printf("Name:     %s\n", $val->name);
               printf("Table:    %s\n", $val->table);
               printf("max. Len: %d\n", $val->max_length);
               printf("Flags:    %d\n", $val->flags);
               printf("Type:     %d\n\n", $val->type);
       }
           $result->close();
    }

    /* close connection */
    $maxdb->close();
    ?>

    Example #2 절차식 형식

    <?php
    $link     = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

    /* check connection */
    if (maxdb_connect_errno()) {
           printf("Connect failed: %s\n", maxdb_connect_error());
       exit();
    }

    $query = "SELECT name, cno from hotel.customer ORDER BY cno";

    if (    $result = maxdb_query($link, $query)) {

           /* Get field information for all columns */
           $finfo = maxdb_fetch_fields($result);

       foreach (    $finfo as $val) {
               printf("Name:     %s\n", $val->name);
               printf("Table:    %s\n", $val->table);
               printf("max. Len: %d\n", $val->max_length);
               printf("Flags:    %d\n", $val->flags);
               printf("Type:     %d\n\n", $val->type);
       }
           maxdb_free_result($result);
    }

    /* close connection */
    maxdb_close($link);
    ?>

    위 예제의 출력 예시:

    Name:     NAME
Table:
max. Len: 10
Flags:    -1
Type:     2

Name:     CNO
Table:
max. Len: 4
Flags:    -1
Type:     0
