Not getting database table updated

I am simply writing an INSERT query开发者_JAVA技巧 to insert values into the table, when I click the submit button the code runs successfully, I don't get any error.

But when I look into the table it shows no data i.e the table is not updated. I don't know why it's happening. Can anyone suggest me.

thank you

I had the same problem if you are using c# windows application probably you have two different data base connection one updated and another still not updated so check your connections and if you are using sql express your database might be replicated in you debug directory so check your debuge folder or run your application from executable file.
