pg_field_table

(PHP 5 >= 5.2.0, PHP 7, PHP 8)

pg_field_table — Returns the name or oid of the tables field

Açıklama

pg_field_table(PgSql\Result $result, int $field, bool $oid_only = false): string|int|false

pg_field_table() returns the name of the table that field belongs to, or the table's oid if oid_only is true.

Bağımsız Değişkenler

result

pg_query(), pg_query_params() veya pg_execute() işlevinden dönen PgSql\Result nesnesi.

field

Field number, starting from 0.

oid_only

By default the tables name that field belongs to is returned but if oid_only is set to true, then the oid will instead be returned.

Dönen Değerler

On success either the fields table name or oid, başarısızlık durumunda false döner.

Sürüm Bilgisi

Sürüm: Açıklama
8.1.0 sonuç bağımsız değişkeni artık PgSql\Result nesnesi kabul ediyor, evvelce bir özkaynak kabul ederdi.

Örnekler

Örnek 1 Getting table information about a field

<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");

$res = pg_query($dbconn, "SELECT bar FROM foo");

echo pg_field_table($res, 0);
echo pg_field_table($res, 0, true);

$res = pg_query($dbconn, "SELECT version()");
var_dump(pg_field_table($res, 0));
?>

Yukarıdaki örnek şuna benzer bir çıktı üretir:

foo
14379580

bool(false)

Notlar

Bilginize:

Returning the oid is much faster than returning the table name because fetching the table name requires a query to the database system table.
