Syncronize Database

I use mysql and can not syncronising database and application that i made.
If i delete one column in database. Column that i delete still appear in application. Any idea for solution ??

If your application is a form then you can go to application -> synchronize. Then you have to adjust the changes in your application. For grids this is not an automated process, you need to go to the sql section and apply the changes manually. After saving the sql you need to adjust your application to whatever is necessary.

thanks Albert is clear for me about your answer.
Now I can work again with my project
