Good point. I have just added test for descending order:
||[3.11|https://github.com/apache/cassandra/compare/cassandra-3.11...adelapena:10271-3.11]||[trunk|https://github.com/apache/cassandra/compare/trunk...adelapena:10271-trunk]||
I am running another CI round just in case.

Benjamin Lerer commented on CASSANDRA-10271:
Thanks for the patch.
I have only a minor nit.
Could you add some tests to test descending ordering? All the valid queries use
the ascending order which is the default one. If the ordering was broken when
some columns are missing the test will not show it.

Here are new versions of the patch addressing the comments:
||[3.11|https://github.com/apache/cassandra/compare/cassandra-3.11...adelapena:10271-3.11]||[trunk|https://github.com/apache/cassandra/compare/trunk...adelapena:10271-trunk]||
The validation is made with {{StatementRestrictions#isColumnRestrictedByEq}},
exactly as it is suggested by [~blerer]. I have also overridden
[{{MultiColumnRestriction.EQRestriction#isEQ}}|https://github.com/adelapena/cassandra/blob/889b95d7a7e9a0152d34cba87fcd2fe42c5c3414/src/java/org/apache/cassandra/cql3/restrictions/MultiColumnRestriction.java#L139-L143]
to accept queries like these:
{code}
SELECT * FROM foo WHERE a = 0 AND (b, c) = (0, 0) ORDER BY c;
SELECT * FROM foo WHERE a = 0 AND (b, c) IN ((0, 0)) ORDER BY c;
{code}
The unit test is adapted to the desired behaviour and it uses
{{assertInvalidMessage}} instead of {{assertInvalid}}.
I ran the patch on our internal CI. There are not failures for the unit tests
and the failing dtests seem not related to the change.

Benjamin Lerer commented on CASSANDRA-10271:
Thanks for the patch and sorry for the delay.
Based on your unit tests, I think there is some misunderstanding in what should
be allowed or not.
Basically, we want to allow to skip a column in the {{ORDER BY}} clause if the
clustering column is restricted by an {{=}} or an {{IN}} with only one
restriction.
So the following tests:
{code}
assertRows(execute("SELECT * FROM %s WHERE a=? AND b ORDER BY should allow skipping equality-restricted clustering columns

No, I just got sidetracked from getting back at it until today. Attached is a
new patch for 3.x. Let me know what other modifications it may need. It now
supports the other query patterns you and Tyler mentioned earlier in the thread.
I do get one test failure after making the changes in the other existing unit
tests in SelectOrderByTest.
java.lang.AssertionError: Query should be invalid but no error was thrown.
Query is: SELECT v FROM %s WHERE k = 0 ORDER BY k DESC (values: [])
Wasn't sure if that condition should be removed or if my changes go a bit too
far and are not restrictive enough to prevent that.
Thanks!

[~blerer] Should this only be done in 3.x branch now? It appears

[~bsnyder788] CASSANDRA-10707 has been committed.
The code now convert {{IN}} restrictions with only one element into {{EQ}}
restrictions. By consequence, you can simply use the
{{SelectStatement::isColumnRestrictedByEq}} method. It is use for the {{GROUP
BY}} clause
[here|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/cql3/statements/SelectStatement.java#L1071].

(CASSANDRA-10707). If you can wait for it, it will simplify the work needed for

+1, it would be good to allow that as well. However, if that turns out to be
more difficult to generalize for some reason, I would be okay with deferring
that to another ticket.

Benjamin Lerer commented on CASSANDRA-10271:
[~bsnyder788] Sorry, I realized that my previous comment was not clear.
The following queries should be valid:
* {{SELECT * FROM %s WHERE a=? AND b=? AND c >= ? ORDER BY c ASC}}
* {{SELECT * FROM %s WHERE a=? AND b=? AND c IN (?, ?) ORDER BY c ASC}}
* {{SELECT * FROM %s WHERE a=? AND b=? AND (c , d) > (?, ?) ORDER BY c ASC, d
ASC}}
As the order is specified for the {{c}} and {{d}} columns we should allow them.
We should probably even allow queries like:
{{SELECT * FROM %s WHERE a=? AND b IN (?, ?) AND c = ? ORDER BY b ASC}}
[~thobbs] What do you think?

Benjamin Lerer commented on CASSANDRA-10271:
Thanks for the new patch.
Your patch does not seem to handle cases like:
* {{SELECT * FROM %s WHERE a=? AND b=? AND c >= ? ORDER BY c ASC}}
* {{SELECT * FROM %s WHERE a=? AND b=? AND c IN (?, ?) ORDER BY c ASC}}
* {{SELECT * FROM %s WHERE a=? AND b=? AND (c , d) > (?, ?) ORDER BY c ASC, d
ASC}}
You should also add some unit tests for post-ordering. For queries like:
* {{SELECT * FROM %s WHERE a IN (?, ?) AND b=? ORDER BY c ASC}}
* {{SELECT * FROM %s WHERE a IN (?, ?) AND b=? AND c >= ? ORDER BY c ASC}}
{quote}
Wasn't really sure the best way to approach restricting to an IN restriction
with only one value.
{quote}
{{SingleColumnRestriction}} and {{MultiColumnRestriction}} support 2 types of
{{IN}} restrictions: with values (e.g. {{b IN (?, ?, ?)}}) and with marker
(e.g. {{IN ?}}). In the case of {{IN}} with values you can check the number of
terms.

Benjamin Lerer commented on CASSANDRA-10271:
I had a look at the patches.
* The patches check if the previous clustering columns are restricted. It
should also check that the restriction is an equals one or an IN restriction
with only one value.
* Could you add some unit tests to check the behavior of the patch and add an
entry to the {{NEWS.txt}} ?
As a nit: you should use the {{subList}} method instead of creating it using a
loop.

> Given a table like the following:
> {noformat}
> CREATE TABLE foo (a int, b int, c int, d int, PRIMARY KEY (a, b, c));
> {noformat}
> We should support a query like this:
> {noformat}
> SELECT * FROM foo WHERE a = 0 AND b = 0 ORDER BY c ASC;
> {noformat}
> Currently, this results in the following error:
> {noformat}
> [Invalid query] message="Order by currently only support the ordering of
> columns following their declared order in the PRIMARY KEY"
> {noformat}
> However, since {{b}} is restricted by an equality restriction, we shouldn't
> require it to be present in the {{ORDER BY}} clause.
> As a workaround, you can use this query instead:
> {noformat}
> SELECT * FROM foo WHERE a = 0 AND b = 0 ORDER BY b ASC, c ASC;
> {noformat}
