JOIN vs. WHEREThanks for your thoughts, Jörgen. Of course the results differ, and to achive the correct result, one have to write
AND NVL( F.OtherID, 1 ) = 1

My personal pet peeve is that a field should always have the same name everywhere in a database just like the ISO standard says
Don't know where you read this, but it cannot be right ... Even in my original simple example you have two addresses in tho ORDERS table, so there is no chance in having 'the same field always the same name'. Maybe you meant that a field with the same MEANING should have always the same name, like CUSTOMER, FORWARDER etc. ?

JOIN vs. WHERE -
JOIN vs. WHEREWell - the title should be clear enough, and I presented JOIN syntax and WHERE syntax, expressing my worry about noone seems using WHERE. THEN I asked for arguments - obviously (I thought so) WHY noone is using WHERE syntax, and NOT to support my preference. In other words: Are there any points (other than preference) to not using WHERE syntax ??

Yeah - a really qualified Response ... I ask for arguments, an your resposne is

I will [...] have a short, sharp discussion with the dev that uses it
THIS is my Intention - to have a DISCUSSION about it ! But you have obvoiously no arguments, but prejudices against it - not the ideal base for discussions. What would be your arguments in a discussion with your developer - do you even have any arguments ? Note: I asked politely for arguments for - or against - my preferation, because (as every of us) I want to improve my abilities, and also to give some impressions to SQL newbies to decide what to do, and not to do. So ... HAVE VOU ARGUMENTS, or are you just felt to open your mouth ... ?

JOIN vs. WHEREI quite don't understand why noone is using the WHERE-Syntax for table joining ... I always see something like
SELECT O.Order_No, C.Address, F.Address
FROM Orders O
JOIN Address C
ON O.Customer = C.ID
JOIN Address F
ON O.Forwarder = C.IDFor me, the most irritating thig is the spreading of table names and aliases all over the Statement. I prefer
SELECT O.Order_No, C.Address, F.Address
FROM Orders O, Address C, Address F
WHERE O.Customer = C.ID
AND O.Forwarder = F.ID- It's shorter - All table names and aliases are together Arguments, anyone ?

Time for a new programming language paradigmIn C / C++ the IDE cannot catch it, because it as an absolut correct statement ! Ever seen the simple strcpy() function:
void strcpy( char *source, char *destination )
{
while (*destination++ = *source++ )
;
} -
Time for a new programming language paradigmFire up any text editor, compile the code below as pure C and you have what you asked for ...

#define IS ==
