Question

if a default value was set for a null column, oracle sets the column to the default value. However, if no default value was set when the column was created, oracle inserts an empty space. True or false?

Answer 1

False is the correct answer for the above question

Explanation:

• It is correct that when there is defined a default value for any columns of the database then that value is set if the user does not give any value for that column of that database.
• But when there is no default value set for any column or attributes of the database then while space is not stored when the user does not provide any value for that column of the database.
• When the default value is not set for any column of the database and the user does not provide any value for that column then NULL will set for that column of the database.
• The above question-statement says that the white space is entered if there is no default value set for any column of the database and the user also does not provide any value for that column of the database which is not correct as described below hence False is the correct answer for the above question.
