Tell me which is more likely to be a sum of profits for years since 2013. Excel:
SUM(A100:A112)
SQL: SELECT SUM(yp.profit)
FROM yearly_profitability AS yp
WHERE yp.year > '2012-12-31'::Datetime
(I'm forgetting how to do SQL datetimes, but whatever.)SQL and other programming languages use words to describe the variables. Treating SQL like Excel would be DailyWTF material:
CREATE TABLE sheet1(
a INTEGER,
b TIMESTAMP WITH TIME ZONE
)
