    Unanswered: Adding a column to a database table

    Hello i want to add another bit column to my table.

    Columns were

    userID ---- userName

    Now i want to add a column

    userID ---- userName ---- isSuperUser

    Now i have values in my table.

    I want to add the column isSuperUser to my table and set old row's isSuperUser column to 1 ...

    How can I achieve this?

    Do i need to drop the table and create it again?
