Awesome, crystal.clear and concise. I really found useful the second example, where you go strait and perform filtering operation. In many cases an inner ou nested query would have been used to solve that one but I persornally find it hard to read subqueries under the where clause.
Thank you for the insightful tutorial.

I have a doubt. I have table with two fields, one field is array in table 1
uID | Contact
2 | 1221,1223
3 | 1123
Now value of 1221 and 1223 are in table Two. I want a query to join table 1 and table 2 using array of field2
Is this equivalent to JOINs ?
Yes that can be used as an alternative
