When I do an inner join of two tables: table 1 and table 2,

does the postion of the table matters ?

I mean on the left or right of the inner join, for example
below, do they make any difference?

table1 inner join table2

or

table2 inner join table1

It'll only matter if you start doing query hint overrides... which you should avoid in 99% of circumstances, so yeah... won't matter. :-)
