Hello @juan.delrio , This is very good. I like grouping by category and also the choice of color :-)

I couldn’t find following topics on other day, you could add if these are not explicitly explained elsewhere:

1. Is it AND or OR condition here: 

   from abc
   where category=1, qty=10 (implicit AND or OR ?)

    

2. Is it AND or OR condition here: 

   from abc
   where category=1
   where qty=10 
   (implicit AND or OR? How it differs from previous one?)

3. Devo keyword equivalent to ANSI SQL like top, having etc., maybe in separate page  

Hello Ifekxpd!

example 1:
This is an implicit AND 

It could also be written as “where category=1 AND qty=10

Example 2:

This is also a implicit AND

For 3,  maybe this article will help?
 

@ifekxpd the linqs

from T
  where pred1
  where pred2
  where pred3

---

from T
  where pred1, pred2, pred3

---

from T
  where pred1 and pred2 and pred3

are logically equivalent. Juxtaposition of where filters acts as conjuntion of different predicates (and). All three variants are valid 

Thanks @juan.delrio for creating this awesome reference
