pg_field_type_oid

PHP function Edit on GitHub ✎

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

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

Description

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.

Note

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.

Parameters

result: Result
field: Field number, starting from 0.

Return Values

The OID of the field's base type.
