Question
Alter the Sessions Table: Add a new column SessionDuration to record the duration of each gaming session. The data type INTERVAL DAY TO SECOND is used to store durations.
Solution
To add a new column to the Sessions table, you can use the ALTER TABLE command in SQL. Here's how you can do it:
Step 1: Open your SQL command line client or interface.
Step 2: Connect to the database where the Sessions table is located.
Step 3: Execute the following SQL command:
ALTER TABLE Sessions
ADD SessionDuration INTERVAL DAY TO SECOND;
This command will add a new column named 'SessionDuration' to the 'Sessions' table. The data type of this new column is 'INTERVAL DAY TO SECOND', which is used to store durations.
Please note that the actual syntax might vary slightly depending on the SQL dialect you are using. The above command is written in standard SQL.
