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
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.
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.
The OID of the field's base type.
FALSE is returned on error.
- resource $result: PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
- int $field_number: Field number, starting from 0.
Example #1 Getting information about fields
$dbconn = 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'");
echo "Title field type OID: ", pg_field_type_oid($res, 0);
The above example will output:
Title field type OID: 1043
- 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.
