The following criteria gives a result query duplication.
1. Go to a database and select a table which do not have data. It will direct you to the structure tab. You can see the the result query as "SELECT * ......"
2. Then click on the "Change" option in the column. It will pop up the dialog to edit the table.
3. Click on "Save" and it will show the "ALTER TABLE ...." result query on the structure page.
4. But still the old "SELECT ..." result query is display and it's display under the table columns.
This fix remove this extra result query. Since this is a noticeable issue I did a quick fix.
This whole functionality need a full refacotring and I'll will do it soon.
