(PHP 5 >= 5.2.0, PHP 7)
Returns the name or oid of the tables field
mixed pg_field_table ( resource $result, int $field_number [, bool $oid_only = false ] )
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.
Returns:
On success either the fields table name or oid. Or, FALSE
on failure.
Notes:
Returning the oid is much faster than returning the table name because fetching the table name requires a query to the database system table.
Examples:
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)
