pg_field_type_oid

    (PHP 5 >= 5.1.0, PHP 7, PHP 8)

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

    Descrição

    pg_field_type_oid(PgSql\Result$result, int$field): string|int

    pg_field_type_oid() returns an integer containing the OID of the base type of the given field in the given result instance.

    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.

    Nota:

    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.
