Most of the time, if you need more than one thing from the database, you can combine them into one query.

For example, if you want a list of employees, as well as a total count of employees, you could use a query like this:

SELECT emp.name,
       emp.salary,
       COUNT(*) OVER () AS total_count
FROM   employees emp;

two queries at the same time? or do you want to use the result of one query as the input for the next one? if thats the case, use subqueries
