Is MAX, MIN, SUM SQL command standard accross diffrent RDBMS

I only have MySQL installed right now but will these work fine when run in PgSQL, MS SQL, etc.?

SELECT MAX(field) as max_field FROM table
SELECT MIN(field) as max_field FROM table
SELECT SUM(field) as max_field FROM table

You could check for yourself, but aggregate functions are common across most, if not all, RDBMS:

• H2 aggregate functions
• Oracle aggregate functions
• PostgreSQL aggregate functions
• SQL Server aggregate functions

You get the idea.
