What will be the output of the following MySQL command?

SELECT *
FROM employee
WHERE (title=’HEAD TELLER’) AND (start_date=2013-01-24);

This question is about understanding how the WHERE clause works in MySQL.
The WHERE clause is used to filter the data in a table.
Let's break down the command:
SELECT *: This part tells MySQL to select all columns (*) from the table.
FROM employee: This part specifies the table name we're working with, which is "employee."
WHERE (title='HEAD TELLER') AND (start_date=2013-01-24); This is the key part. It filters the data.
* (title='HEAD TELLER'): This part filters rows where the "title" column has the exact value "HEAD TELLER." * (start_date=2013-01-24): This part filters rows where the "start_date" column has the exact value "2013-01-24". * AND: The "AND" operator combines both conditions. It means that only the rows which satisfy *both* conditions will be included in the result.
So, the correct answer is Option B: All columns but only those rows which contain 'HEAD TELLER' as a "title" and 2013-01-24 as a "start_date".
In simple terms: This command will only show you the information about employees who have the title "HEAD TELLER" and started working on January 24, 2013.
