cubrid_field_seek — 将结果集游标移动到指定的字段偏移量
此函数将结果集游标移动到指定的字段偏移量。此偏移量由 cubrid_fetch_field() 使用，如果它不包含字段偏移量。它在成功时返回 TRUE，在失败时返回 FALSE。
resultresult 来自对 cubrid_execute() 的调用
field_offset数字字段偏移量。 field_offset 从 0 开始。如果 field_offset 不存在，也会发出 E_WARNING 级别的错误。
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--- 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);
?>上面的示例将输出
