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


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.

注: 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.



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


Field number, starting from 0.


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

例子 1. Getting information about fields

= 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'");

"Title field type OID: ", pg_field_type_oid($res, 0);


Title field type OID: 1043
