If you have any idea about this please share me. Your help is definitely appreciated.

Table Structure

Query (I tried this myself but i am confused regarding this also working)

UPDATE `table` SET STATUS = 0;
UPDATE `table` SET STATUS = 1 WHERE id = 4;

My Question is how to combine these queries in one query

Answer 1

To update all rows but one:

UPDATE `table` SET STATUS = 0 WHERE id <> 4;

If you need to explicitely set the status of the row where id = 1, I suggest you do it in a second separate query.

If you really want to do it in one query:

UPDATE `table` SET STATUS = IF(id = 4, 1, 0);
