Realizing that you will only see this as one more invalid opinion, I must
disagree with this statement.

I taught OPNQRYF since release 8 of the 38 and found that there was
significantly more confusion about things like counting quotes on variable
insertions into the select and mapping to a file format for joins, than I
ever get about left, right, inner or exception joins in SQL.

Second, AS/400 people have been using OPNQRYF for a lot longer than most of
them have been using SQL, which is why you see more questions about SQL now
than OPNQRYF. Not because OPNQRYF is easier to understand.

As for people getting lost in the statements, I have found more people get
lost in nested DOW, DOU loops than in SQL statements.

But hey, it's just my opinion, which you can easily ignore.
