After logging the results of the "Quantum Entanglement Study" experiment, Brayden realizes he needs to make some changes to the database tables. Here are the actions he takes:Drop the table named Qubits as it is no longer needed in his database.Alter the Experiments table to add a new column named ResearcherID to store the unique identifier with the data type of NUMBER for each researcher involved in the experiments.
Question
After logging the results of the "Quantum Entanglement Study" experiment, Brayden realizes he needs to make some changes to the database tables. Here are the actions he takes:Drop the table named Qubits as it is no longer needed in his database.Alter the Experiments table to add a new column named ResearcherID to store the unique identifier with the data type of NUMBER for each researcher involved in the experiments.
Solution
To implement the changes Brayden wants to make, follow these steps:
-
Dropping the Qubits table:
- Use the DROP TABLE command to delete the Qubits table from the database. The syntax for this command is:
DROP TABLE table_name;. So in this case, it would be:DROP TABLE Qubits;.
- Use the DROP TABLE command to delete the Qubits table from the database. The syntax for this command is:
-
Altering the Experiments table:
- Use the ALTER TABLE command to add a new column to the Experiments table. The syntax for this command is:
ALTER TABLE table_name ADD column_name column_type;. So in this case, it would be:ALTER TABLE Experiments ADD ResearcherID NUMBER;.
- Use the ALTER TABLE command to add a new column to the Experiments table. The syntax for this command is:
Please note that these commands are written in SQL (Structured Query Language), which is the standard language for managing data held in a relational database management system.
