Question

How do I write an SQL query to find out which employees are from a single location where employee and location are different table.

select count(*) from employee;    

The above gives only the count of employees but I need to display their name and location

Answer 1

COUNT will obviously give you only the count of the number of employees.

For specific columns such as ‘name’ and ‘location’, just do:

SELECT e.name, l.location 
FROM employee e
JOIN location l ON e.location_id = l.location_id

(or JOIN on whatever is the common association column between the employee and location table)
