Bhaiyaaa u r great🌟

when i apply check constraint in a column and enters a value in the table that does not obey the check constraint then mysql should show error but rather than showing error it executes successfully and the data gets entered in the table
Can you tell why is it happening ????????

Basically according to set theory in mathematics we can say, Primary key is the super set of Unique key and Not Null key, or Not Null and Unique key is the subset of Primary key, or we can say Primary key is the union of Not Null key and Unique key.
