pg_field_type_oid

(PHP 5)pg_field_type_oid --

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

Описание

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.

Замечание:

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.

Список параметров

Возвращаемые значения
