👉 Today's Topics:
SQL Constraints:
Constraints are nothing but the conditions/restriction/limitations/rule/instruction that we should apply on top of columns in a table.

Primary Key: This constraint will make sure that all the values on a column of a table are satisfying the given condition/criteria that we had set while
creating table.

Foreign Key:It refers to a common column that is existing in one or
more tables.
