pg_field_type_oid

(PHP 5 >= 5.1.0)

pg_field_type_oid — Returns the type ID (OID) for the corresponding field number

Description

int pg_field_type_oid ( resource $result , int $field_number )

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.

Return Values

The OID of the field's base type. FALSE is returned on error.

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
