Hello. I went into the SQL and executed this code
SELECT DATE_FORMAT(`dateend`, '%d.%m.%Y') FROM `main`
where main - is the table and dateend is the column
And my answer, here is the message:
"This selection does not contain a unique column. Change the grid setting show, editing, copying and deleting is impossible."
If you can see at the bottom, as it were, changed the date format, but if I go back to the table, there will be the old date format. Prompt how to be? How to change the date format like this: DD.mm.yyyy?
