RMySQL cannot insert new data

Question

I try to insert new data to MySQL using RMySQL. Only for this case I always fail and always get the same warning message. The message was:

Warning message:
In value[[3L]](cond) : corrupt resultSet, missing fieldDescription

Although it just a warning, I never find my data show on MySQL.

Complete code and warning message shown as below:

Please advise any solution.

Oh, Please, don't forget to un-comment library(RMySQL) [ line : 1 ]. & Please, add query in lieu of "select age from Customers". [ line : 9 ]. :)

Maybe, it'll works fine.
