A string that describes the error. An empty string if no error occurred. EXAMPLES
Example #1 Object oriented style <?php /* Open a connection */ $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } $maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city"); $maxdb->query("INSERT INTO temp.mycity SELECT * FROM hotel.city"); $query = "SELECT name, zip FROM temp.mycity ORDER BY name"; if ($stmt = $maxdb->prepare($query)) { /* drop table */ $maxdb->query("DROP TABLE temp.mycity"); /* execute query */ $stmt->execute(); printf("Error: %s. ", $stmt->error); /* close statement */ $stmt->close(); } /* close connection */ $maxdb->close(); ?> Example #2 Procedural style <?php /* Open a connection */ $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city"); maxdb_query($link, "INSERT INTO temp.mycity SELECT * FROM hotel.city"); $query = "SELECT name, zip FROM temp.mycity ORDER BY name"; if ($stmt = maxdb_prepare($link, $query)) { /* drop table */ maxdb_query($link, "DROP TABLE temp.mycity"); /* execute query */ maxdb_stmt_execute($stmt); printf("Error: %s. ", maxdb_stmt_error($stmt)); /* close statement */ maxdb_stmt_close($stmt); } /* close connection */ maxdb_close($link); ?> The above example will output something similar to: Warning: maxdb_stmt_execute(): -4004 POS(23) Unknown table name:MYCITY [42000] <...> Error: POS(23) Unknown table name:MYCITY.
