pg_field_table
(PHP 5 >= 5.2.0, PHP 7)
pg_field_table — Returns the name or oid of the tables field
Description
pg_field_table() returns the name of the table that field
belongs to, or the table's oid if oid_only is TRUE.
Parameters
-
result -
PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
-
field_number -
Field number, starting from 0.
-
oid_only -
By default the tables name that field belongs to is returned but if
oid_onlyis set toTRUE, then the oid will instead be returned.
Examples
Example #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));
?>
The above example will output something similar to:
foo 14379580 bool(false)
Notes
Note:
Returning the oid is much faster than returning the table name because fetching the table name requires a query to the database system table.
