Great explanantion Raja!

I had one question though. how can we put this in a loop. Let's say we have multiple columns for each record and it varies for each record. how can we create a code for such a requirement?

Hi I am seeing below issue

cannot resolve 'map('x', `x`, 'y', `y`)' due to data type mismatch: The given values of function map should all be the same type, but they are [timestamp, int];

Can you help here?
