pg_affected_rows
(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)
pg_affected_rows — Returns number of affected records (tuples)
Description
pg_affected_rows() returns the number of tuples
(instances/records/rows) affected by INSERT,
UPDATE, and DELETE
queries.
Since PostgreSQL 9.0 and above, the server returns the number of SELECTed rows. Older PostgreSQL return 0 for SELECT.
Note:
This function used to be called pg_cmdtuples().
Parameters
-
result -
An PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).
Return Values
The number of rows affected by the query. If no tuple is
affected, it will return 0.
Changelog
| Version | Description |
|---|---|
| 8.1.0 |
The result parameter expects an PgSql\Result
instance now; previously, a resource was expected.

$result = pg_query($conn, "INSERT INTO authors VALUES ('Orwell', 2002, 'Animal Farm')");
$cmdtuples = pg_affected_rows($result);
