RE: SQL Difference in V7 vs V6 not in memo to users

I had a customer run into this several months ago, and his application
software broke down.

He hadn't read the MTU, nor had his programmers.

Subject: SQL Difference in V7 vs V6 not in memo to users

Hi All,
I just got bitten by this error today:

Message ID . . . . . . . . . :
SQL0338
Message file . . . . . . . . :
QSQLMSG
Library . . . . . . . . . :

Message ID . . . . . . . . . : SQL0338

Message text . . . . . . . . : JOIN predicate not valid.

V6
R1

Message . . . . : JOIN predicate not
valid.
Cause . . . . . : The JOIN predicate is not valid because a column
is
specified that exists in a table that is outside the scope of the
join
predicate. The scope is generally determined from left to right but is
also
based on the position of the join-condition. If parentheses are
used,
columns inside the parentheses can not come from a table outside
the

parentheses.

Recovery . . . : Do one of the following and try the request
again:
-- Make certain that the column names, table names, and any qualifiers
are
specified
correctly.
-- Specify parentheses around joined tables to specify a join order
other
than left to right. Ensure columns exist in tables that are in the
same

scope.

Message text . . . . . . . . : JOIN predicate or MERGE ON clause not

ause . . . . . : The JOIN predicate, or ON clause of a MERGE statement,
is
not valid because a column is specified that exists in a table that
is

is
generally determined from left to right but is also based on the position
of
the join-condition. If parentheses are used, columns inside the
parentheses
cannot come from a table outside the parentheses. If an implicit join
(using
a comma) is specified prior to a joined table with an ON clause, columns
in
the ON clause cannot come from a table before the
comma.
ecovery . . . : Do one of the following and try the request

-- For an ON clause in a MERGE statement, ensure referenced columns

clause.

join.
