pg_field_table
Returns the name or oid of the tables field
(PHP 5 >= 5.2.0)
mixed pg_field_table ( resource result, int field_number [, bool oid_only] )
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_only is set to
TRUE, then the oid will instead be returned.
Examples
Example 1931. 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.
