MySql and numbers

I really like MySql!

Both queries work:

SELECT * FROM table1 WHERE numbers_column=4

SELECT * FROM table1 WHERE numbers_column='4'

But that's nothing comparing to:

INSERT INTO table1 (numbers_column) VALUES (4)

INSERT INTO table1 (numbers_column) VALUES ('4')

Which means it's generic enough to write a statement without knowing the data type of the columns.
Was quite helpful in my previous project.
