Hi,
I've a column of type VARCHAR(10) where I know the data would be 10-char in length -
always. Apart from the fact that VARCHAR saves space as compared to CHAR, is there any
performance benefit? If yes, is it significant enough?
Thanks.
Hassan
Char is more efficient when selecting but less efficient when storing (wastes space).
It is a trade off so there really isn't a right answer. Do some experimenting and
see what works best for you.

If the data is 10-char in length always, CHAR is better performance-wise.

Hi,

improvement.
Of course, if you have other variable length columns in your table,
MySQL will be stupid and change your CHAR to VARCHAR, thinking it's
helping you. :-(
