+## Prepared Statements Helper
+
+MySQL2 provides `execute` helper which will prepare and query the statement. You can also manually prepare / unprepare statement with `prepare` / `unprepare` methods.

+```js
+connection.execute(
+  'select ?+1 as qqq, ? as rrr, ? as yyy',
+  [1, null, 3],
+  (err, rows, fields) => {
+    console.log(err, rows, fields);
