pg_field_type_oid

(PHP 5 >= 5.1.0RC1)

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

result

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

field_number

Field number, starting from 0.

Возвращаемые значения

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