Which statement would add a column CGPA to a table Student which is already created in SQL?

To add a column named CGPA to an already created table Student in SQL, you would use the ALTER TABLE command. Here is the step by step process:

1. Open your SQL command line client or interface.
2. Connect to the database where the Student table is located.
3. Run the following SQL command:

ALTER TABLE Student
ADD COLUMN CGPA decimal(3,2);

This command does the following:

• ALTER TABLE Student: This tells SQL that you want to change the structure of the table named Student.
• ADD COLUMN CGPA decimal(3,2);: This tells SQL that you want to add a new column named CGPA. The decimal(3,2) part specifies the data type of the new column. In this case, it's a decimal number that has 3 digits in total, 2 of which are after the decimal point.

Please replace decimal(3,2) with the actual data type and size that suits your needs.
