Question

If you wanted to display records of all employees who live in the same city (from the City field in the table), you would use a ___________.

1) SELECT statement
2) JOIN statement
3) WHERE statement
4) GROUP BY statement

Answer 1

The correct answer is to use a GROUP BY statement in SQL to display records of employees who live in the same city, which aggregates the records based on the city field.

If you wanted to display records of all employees who live in the same city (from the City field in the table), you would use a GROUP BY statement. This SQL clause is used to aggregate records that have the same values in certain columns, in this case, the City column. By grouping the records, you can then use additional clauses like HAVING to further filter your results or SELECT to specify the columns to be displayed. Here's an example of how you might write the query:

SELECT City, COUNT(*)
FROM Employees
GROUP BY City;

This SQL statement will list each city once alongside the count of employees living in that city, effectively grouping the records according to the city they live in.
