    Hi,
    Thanks for the videos. About the "Default" which is not listed as a constraint, I think that is because Default is a one-off thing rather than a continuous constraint on a field. Maybe that is why it is not listed as a constraint. I mean the value of the field can be changed with no limitation after the default value is assigned to the field. Thanks anyway!

    Hello, I created a table users. It also said 'Table USERS created'. However the table doesn't show in the overview on the left (Tables (Filtered). What did i wrong?

      It is there. You just need to refresh 'Tables'

      @@ewaskorska2013 She is correct. It did not show on mine either, but right clicked in tables, refreshed and it showed.

    I could be wrong on this but it looks like DEFAULT is an initializer. Like coding in C# and you set the value to 0.

    Error report -
    ORA-00955: name is already used by an existing object
    00955. 00000 - "name is already used by an existing object"
    I dropped the table why do I continue to get this?
