Why does MySQL procedure stops executing upon running into an error? How to I allow it to continue?
I finally figured out the solution. I would like to post the answer to help out anyone that is running into the same issue. The solution is to DECLARE CONTINUE HANDLER FOR SQLEXCEPTION Continue Handler will allow the code to run even if there was an error. from there I set the sqlstate and errorno then I store them and move on. Here is my final code. DELIMITER $$ CREATE DEFINER=`root`@`10.%`

Timediff in mysql not returning result
As per the docs: TIMEDIFF() returns expr1 – expr2 expressed as a time value. expr1 and expr2 are time or date-and-time expressions, but both must be of the same type. You're feeding in a time (curtime()) and a datetime (approved). Change it to select timediff(curtime(), time(approved)) ... instead, assuming approved is a datetime type, and not char/varchar.

How to delete half the records of a table?
It looks like the relationships exist in pairs. So user A has user B as a friend and user B has user A as a friend. If I read your question right, you want to remove one of the relationships but leave the other. Since they have different user_ids, you could delete all the rows where user_id is greater than friend_user_id. That would delete one of the relationships but keep the other. delete tabl

Mysql timediff skips sunday and some hours of days
You could introduce your own calendar, that only counts working seconds starting at some fixed date. Then you could do calculations as you would with normal timestamps and get the "working seconds" between two timestamps. You would need a layer of logic that will transform real dates into the "working seconds measure". You would need to decide if a) Day 1, 18:00h = Day 2, 09:00h or b) Day 1, 1

Is having flag in database better than querying a table every time?
It sounds like the design decision you are going back and forth on is a special case of what is called "materializing a view". A view stores a query, and makes the result available as a table. A materialized view stores the result of the query. The pros and cons you have discovered are real. In the case of a single flag, that's extremely space efficient, and therefore time efficient as well.
