示例

示例 #1 cubrid_field_seek() 示例

<?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--- 字段属性 ---\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);
?>

以上示例将输出

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