Question

I am using mySql and I have a record with is in end of the table. I want to bring it to the top of the table. How can move it? I mean there are entries at top of the table, how can i replace ids of both the entries with each other.

I want to do this because i want to move the last item to the start of the list, so that it appears first on my website.

thanks

I suppose a simple ORDER BY in the select query will not satisfy your needs, so here is a way to physically replace row with id = 123 with row id = 1 assuming your table has more than 123 rows

update table_name set id=(select max(id)+1) from table_name where id=123;
/* this will move the last record to somewhere temporary */

update table_name set id=123 where id=1 ;
/* this will move the first row to the place of the row that was at the bottom */

update table_name set id=1 where id=(select max(id) from table_name);
/* moving from temporary row to the first of the table */
