pg_field_type_oid
Returns the type ID (OID) for the corresponding field number
Description
stringint pg_field_type_oid(PgSql\Result $result
, int $field
)
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
-
An PgSql\Result instance, returned by pg_query,
pg_query_params or pg_execute(among others).
-
field
-
Field number, starting from 0.
Return Values
The OID of the field's base type.
Examples
Example #1 Getting information about fields
<?php
$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
