Question

Hi,
There is a table with lot of data. I want to change the order in which the columns are displayed when the table is queries. Is there any way or i just have to drop the table and recreate again.
Have a nice day.
Thank you

Hi,
Like user637951 said, you only need to change the order in your query. Example:
