php - Why does COALESCE order results in this way? -

i have table 3 columns, id, comment, , parent. if parent id null, comment root comment, , if not, means comment reply another. use following query: select * `comment` order coalesce( parent, id ) desc limit 0 , 30 this query orders last inserted comment it's replies, don't understand logic. why ordered way? the coalesce() function returns first non-null argument received. so, if go through each row , compare parent/id column, you'll see ordered this: 7 (because parent null) 2 (because parent null) 2 (parent not null, used) 1 (because parent null) 1 (parent not null, used) 1 (parent not null, used) which in descending order, specified. i suspect there may confusion here. let me reiterate. coalesce(parent, id) return first value out of 2 not null . if parent not null, returned. if null, falls on id , returns that. if @ list of rows side side , see return values, may more clear: | parent | id | return_value | +--------+----+--------------+ |...
