So you mean to replace joining with combined condition?
I think it is simply a terminological/syntactical difference. I simply
never use LEFT JOIN commands. I always use '='. I think they do the same
think, namely what is called a join in relational _theory_. I
*understand* '=' better then
I know KR (section 4.9, 2nd ed.) says
char s[] = ...;
is equivalent to
char s[] = { . . . , '\0'}
but I always explicitely attach the \0 just to be sure i.e.
char s[] = ...\0;
