# cubrid_field_seek

(PECL CUBRID >= 8.3.0)

cubrid_field_seek — Move the result set cursor to the specified field offset

### 说明

cubrid_field_seek ( resource `$result` [, int `$field_offset` = 0 ] ) : bool

This function moves the result set cursor to the specified field offset. This offset is used by cubrid_fetch_field() if it doesn't include a field offset. It returns TRUE on success or FALSE on failure.

### 参数

`result`

  `result` comes from a call to cubrid_execute()

`field_offset`

  The numerical field offset. The `field_offset` starts at 0. If `field_offset` does not exist, an error of level `E_WARNING` is also issued.

### 返回值

`TRUE` on success.

`FALSE` on failure.

### 范例

Example #1 cubrid_field_seek() example

    <?php
    $conn = cubrid_connect("localhost", 33000, "demodb");
    $req = cubrid_execute($conn, "SELECT event_code,athlete_code,nation_code,game_date FROM game WHERE host_year=1988 and event_code=20001;");

    var_dump(cubrid_fetch_row($req));

    cubrid_field_seek($req, 1);
    $field = cubrid_fetch_field($req);

    printf("\n--- Field Properties ---\n");
    printf("%-30s %s\n", "name:", $field->name);
    printf("%-30s %s\n", "table:", $field->table);
    printf("%-30s \"%s\"\n", "default value:", $field->def);
    printf("%-30s %d\n", "max length:", $field->max_length);
    printf("%-30s %d\n", "not null:", $field->not_null);
    printf("%-30s %d\n", "unique key:", $field->unique_key);
    printf("%-30s %d\n", "multiple key:", $field->multiple_key);
    printf("%-30s %d\n", "numeric:", $field->numeric);
    printf("%-30s %s\n", "type:", $field->type);

    cubrid_close_request($req);

    cubrid_disconnect($conn);
    ?>

以上例程会输出：

    array(4) {
      [0]=>
      string(5) "20001"
      [1]=>
      string(5) "16132"
      [2]=>
      string(3) "KOR"
      [3]=>
      string(9) "1988-09-30"
    }
