PG_FIELD_TABLE(3) PG_FIELD_TABLE(3)
pg_field_table - Returns the name or oid of the tables field
SYNOPSIS
mixed pg_field_table (resource $result, int $field_number, [bool $oid_only = false])
DESCRIPTION
pg_field_table(3) returns the name of the table that field belongs to, or the table's oid if $oid_only is TRUE.
PARAMETERS
o $result
- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).
o $field_number
- Field number, starting from 0.
o $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.
RETURN VALUES
On success either the fields table name or oid. Or, FALSE on failure.
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.
