Hi
Is there any rule govern the join condition in the WHERE clause in
an SQL ?
i.e. the join ( or condition ) has to be from top to bottom or
from left to right , etc. ?
i.e. if I alter the sequence of coding the condition in a WHERE clause would that affect the performance of the query or application ?
thx ....
