FB-1897
The specs for the datetimepart function are, as far as i can tell,
identical to the existing datepart function. Per Pat, replaced the
datepart function with datetimepart rather than just adding
datetimepart as an alias. Made sure existing tests that were using
datepart got switched over.
Second go at this after sorting out weirdness with git.
FB-1896
Added the datetimename function, which returns parts of a timestamp
as strings. Month and day of the week are named ("January", "Monday")
while others are returned as a string of digits ("2023").
Added tests to the test definitions.
* first time quantum queries working
* implement select from timequantum columns
* skip a dax test
* make linter happy
* addressed review feedback
* reverted over eager test elimination
This forward-ports a number of tests from the previous SQL
implementation. The porting is approximate in a number of ways,
and not all tests are implemented/tested yet.
In particular, several tests are currently disabled because
we don't support `limit n` constructs.
The tests that were primarily tests of the parser have been
brought forward as parser tests. One of them has been altered
to add parentheses, because our parser interprets
fld1 between 1 and 3 and fld2 = 2
as:
fld1 between (1 and 3) and (fld2 = 2)
which is invalid, while the old parser apparently interpreted it
as:
(fld1 between 1 and 3) and (fld2 = 2)
We have not yet verified the SQL spec's requirements here, but
sqlite agrees with our old parser, not our new parser, so this
may be a regression.
The old tests expected an INNER JOIN to suppress duplicate
values. Our new code does not, which is consistent with other
SQL implementations. This is a change, but the old behavior
appears to have been wrong. (You can still suppress duplicate
values by specifying DISTINCT.)
In the previous implementations, a value like `count(*)` had
`count(*)` as its column name. In the new implementation,
it has an empty string as its column name.
Related to this, the prior implementation allowed you to
write
select age, count(*) from grouper group by age having count > 1
but the new implementationt requires that to be spelled as
having count(*) > 1
This is consistent with other SQL implementations, so I think
the new behavior is correct.
The behavior of SHOW COLUMNS and SHOW TABLES has changed, in
that the specific results returned are significantly different.
Perhaps more significantly, the old system spelled the former
query as SHOW FIELDS, rather than SHOW COLUMNS. This may be
considered a regression, in that `SHOW FIELDS` no longer works,
and we should consider whether any hypothetical users might
have been relying on the output of either of these. (I hope
not, the new output is much better.)
Some of the old tests (the ones in handler_test) were accommodated
by adding a couple of specific test cases to existing tests,
specifically:
* handling timestamp values with `Z` rather than `+00:00`
* a join with a WHERE clause referring to fields in both
source tables
We introduce a new "partial" comparison type, because there's
no way for a test of `SHOW TABLES` to contain a correct table
row, because `SHOW TABLES` includes timestamps from when tables
were created. I'm not sure this is the right way to do this.
We add corresponding changes to dax_test, because the DAX tree
tests against the SQL tests.
We change the returned types of field names and field types to
plain strings, ironically because DAX needs this -- the test code
in the DAX tree is getting them back as plain strings, rather
than as dax.FieldName and dax.BaseType.
The tests using `having` are commented out because they don't
seem to be working, a ticket has been filed for this.
Two of the tests that should return strings are instead returning
untranslated integer IDs, but only for DAX, not for the regular
SQL tests, and the `delete` test has been commented out for
DAX-specific errors. If we merge this, the next step is to
ticket those and address them separately.
