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

Descrierea

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.

Notă:

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.

Parametri

result

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

field_number

Field number, starting from 0.

Valorile întoarse

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

Exemple

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);
?>

Exemplul de mai sus va afișa:

Title field type OID: 1043
