• What's the best replacement for timeGetTime to avoid wrap-around?

  - by phjr

  timeGetTime seems to be quite good to query for system time. However, its return value is 32-bit only, so it wraps around every 49 days approx. It's not too hard to detect the rollover in calling code, but it adds some complexity, and (worse) requires keeping a state. Is there some replacement for timeGetTime that would not have this wrap-around problem (probably by returning a 64-bit value), and have roughly the same precision and cost?

• Randomly selecting a limited number of records with two conditions in MySQL

  - by andyashton

  I have a MySQL table with a column called "priority". The column can have two values: high or low. I want to select 8 records from the table at random, but I want 6 of them to be high priority, and 2 of them to be low priority. If possibly, I would like to do it in one SQL statement. Is there any way to do two LIMITS in one query based on this kind of criteria?
