Example #1 pg_copy_to() example
<?php
$db = pg_connect("dbname=publisher") or die("Could not connect");
$rows = pg_copy_to($db, $table_name);
pg_query($db, "DELETE FROM $table_name");
pg_copy_from($db, $table_name, $rows);
?>
You cannot specify the schema name in this command. You can change the search path for just one query by using the following code:
<?php
pg_query($conn, "SET search_path TO myschema;");
$copy_to = pg_copy_to($conn, 'tablename');
pg_query("RESET search_path;");
?>
"It issues COPY TO SQL command internally to insert records"
I suspect this statement is incorrect, or that s/insert/retrieve/ is appropriate.
