In php myadmin it says it is no use in defining auto increment column as primary key for table. you can remove primary key constrain. (since both do the same job like).

Is this true. should I remove primary key constrain?

won’t it good to have a primary key column for where clause rather than auto increment column

    Keep The PK constraint. It will save you from some trouble:

    • if you intend to use some frameworks which check for this constraint to determine which columns are used as PK. They will be lost or require additional configuration if the constraint is not present.
    • When you’ll use DB design software it will work better if your DB is properly designed.
    • When you’ll have to change your DB software (upgrade or change brands) You will be happy to have all the constraints properly defined in your SQL statements.
