Hi all, consider I want to compare one field stored in two tables (the field being a key in both tables), like
SELECT table1.field FROM table1, table2 WHERE table1.field=table2.field I have the choice (I'm developping the datamodel right now) to define this field as an INT(6) or as an VARCHAR(6). The question is: if I only store numerical values in this field, what definition (INT or VARCHAR) will be the fastest in the query above? More general: are INT-fields faster of slower in this kind of comparisons? PS. The reason I'm considering VARCHAR is that it might be possible I need to store characters in the field, in stead of only figures.
