Ejemplo #1 Ejemplo con pg_copy_to()
<?php
$db = pg_connect("dbname=publisher") or die("Conexión imposible");
$rows = pg_copy_to($db, $table_name);
pg_query($db, "DELETE FROM $table_name");
pg_copy_from($db, $table_name, $rows);
?>"It issues COPY TO SQL command internally to insert records"
I suspect this statement is incorrect, or that s/insert/retrieve/ is appropriate.Worth noting here that just like the COPY TO statement in PostgreSQL, '$table_name' can include a list of columns or be a select query as well.
e.g.:
$rows = pg_copy_to($db,'schema."TableName" (column1, column2, ...)';
$rows = pg_copy_to($db,'(SELECT ...)');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;");
?>
