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

˵��

pg_field_type_oid ( resource $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.

����

result

PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).

field_number

Field number, starting from 0.

����ֵ

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

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($res0);
?>
