（PECL CUBRID >= 8.3.0）

cubrid_field_seek — 將結(jié)果集光標(biāo)移動(dòng)到指定的字段偏移量

說(shuō)明

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

此函數(shù)將結(jié)果集游標(biāo)移動(dòng)到指定的字段偏移量。 如果 cubrid_fetch_field（） 使用此偏移量 不包括字段偏移量。成功時(shí)返回 TRUE 或返回 FALSE 失敗。

參數(shù) 

result

result來(lái)自對(duì) cubrid_execute（） 的調(diào)用

field_offset

數(shù)值字段偏移量。從 0 開(kāi)始。如果不存在，則 還會(huì)發(fā)出 E_WARNING 級(jí)錯(cuò)誤。field_offsetfield_offset

返回值 

成功是真的。

失敗時(shí)為 false。

示例 

示例 #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);
?>

以上示例會(huì)輸出：

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

--- Field Properties ---
name:                          athlete_code
table:                         game
default value:                 ""
max length:                    0
not null:                      1
unique key:                    1
multiple key:                  0
numeric:                       1
type:                          integer
