pg_field_table — Returns the name or oid of the tables field
pg_field_table() returns the name of the table that field belongs to, or the table's oid if oid_only
is true
.
result
Uma instância de PgSql\Result, retornada por pg_query(), pg_query_params() ou pg_execute() (entre outras).
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.
On success either the fields table name or oid, ou false
em caso de falha.

Exemplo #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));
?>
O exemplo acima produzirá algo semelhante a:
foo 14379580 bool(false)
Nota:
Returning the oid is much faster than returning the table name because fetching the table name requires a query to the database system table.
