pg_field_type_oid
(PHP 5 >= 5.1.0, PHP 7)
pg_field_type_oid — Returns the type ID (OID) for the corresponding field number
Description
$result
, int $field_number
) : int
pg_field_type_oid() returns an integer containing the
OID of the base type of the given field_number in the
given PostgreSQL result resource.
You can get more information about the field type by querying PostgreSQL's pg_type system table using the OID obtained with this function. The PostgreSQL format_type() function will convert a type OID into an SQL standard type name.
Note:
If the field uses a PostgreSQL domain (rather than a basic type), it is the OID of the domain's underlying type that is returned, rather than the OID of the domain itself.
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.
Examples
Example #1 Getting information about fields
<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
// Assume 'title' is a varchar type
$res = pg_query($dbconn, "select title from authors where author = 'Orwell'");
echo "Title field type OID: ", pg_field_type_oid($res, 0);
?>
The above example will output:
Title field type OID: 1043
