365 Days of Daily Coding – Day 167

Today was an ok day. I wish I was more productive. I think I better read some productivity books my boss was suggesting me especially on how not to get easily distracted and provide maximum focus. I will try meditation in the morning too. Probably go to the garden and do a 30 mins of silent meditation. Cause why not? I have such a lovely open space in my house and I have never really fully utilised them.

For today’s learning, I covered a bit on the treatment of null values for joins. The tables do not join when there are nulls in the target and base table. This was the case for inner join, left semi join and anti join.
