| 2013-07-12 | Two more minor changes to the README. | Carlo Zancanaro |
| 2013-07-12 | Update the README a bunch | Carlo Zancanaro |
| 2013-07-12 | Remove some scrap code that got committed accidentally | Carlo Zancanaro |
| 2013-07-12 | Handle parameter types in the compiler better...The compiler handled them by converting most things to strings and embedding
them in the query, but now I'm trying to put more of them in as query
parameters. The advantage is that his handles types that might be database
specific, or something.
At the moment sequences are handled in the same way as before (with each
element being a separate parameter), but this may be changed in future.

| 2013-07-12 | Assert in jdbc interface to fail early rather than do the wrong thing...When converting dotted fields to maps there's one possible case where it can do
the wrong thing. This should now throw an AssertionError rather than silently
doing the wrong thing.
| Carlo Zancanaro |
| 2013-07-12 | Expose a few more helper functions in clojure-sql.core | Carlo Zancanaro |
| 2013-07-12 | Add a rename helper to turn queries into "subobjects" in the result....Essentially just prefixes a subobject name in front of all fields in a query,
with a dot separating the new prefix and the original name.

| 2013-07-06 | Make `sort` able to take expressions rather than just table names. | Carlo Zancanaro |
| 2013-07-06 | Bump the version, put Midje back in as dev dependency | Carlo Zancanaro |
| 2013-07-03 | Add fields to union/intersection result queries | Carlo Zancanaro |
| 2013-07-03 | Remove midje dependency and now useless tests (will add tests later) | Carlo Zancanaro |
| 2013-07-03 | Add SCM info to project.clj | Carlo Zancanaro |
| 2013-07-03 | Added tag 0.1.0 release for changeset a04a90ac3937 | Carlo Zancanaro |
| 2013-07-03 | Update the README to include a leiningen dependency vector | Carlo Zancanaro |
| 2013-07-01 | Bump the version number: 0.1.0 | Carlo Zancanaro |
| 2013-07-01 | Change the condition for union compatible (require projections first) | Carlo Zancanaro |
| 2013-07-01 | Make fields compile in a deterministic order (necessary for union stuff) | Carlo Zancanaro |
| 2013-07-01 | A bit more readme changing | Carlo Zancanaro |
| 2013-07-01 | Add union/intersection to the dsl | Carlo Zancanaro |
| 2013-07-01 | Update the readme some more | Carlo Zancanaro |
| 2013-07-01 | Remove some extra code that was left sitting around | Carlo Zancanaro |
| 2013-07-01 | Update the readme | Carlo Zancanaro |
| 2013-07-01 | Move Midje into dev dependencies - no sense pulling it in transitively | Carlo Zancanaro |
| 2013-07-01 | Make sure you never try to take a negative number of things! | Carlo Zancanaro |
| 2013-06-24 | Remove a midje file that's no longer necessary...Also: the fix I mentioned in my last commit message may be a little bit hard to
do, but even without explicitly detecting it it will explode in an obvious way.
| Carlo Zancanaro |
| 2013-06-24 | Make dotted fields result in nested maps when querying...So now something like this:
(-> (table :users)
(project {:id :user.id, :email :user.email, :person :person.id})
(join (-> (table :people)
(project {:id :person.id, :first-name :person.first-name}))))
will result in a map like this for each result:
{:user {:id 1, :email "..."}, :person {:id 1, :first-name "..."}}
Although I've just thought of an issue that will need to be detected where an
error should be thrown. I'll deal with that now and commit it soon.

| 2013-06-23 | Make sort and group create subqueries to be correct | Carlo Zancanaro |
| 2013-06-23 | Make select take a map and compile to equality tests. | Carlo Zancanaro |
| 2013-06-23 | Misc changes. | Carlo Zancanaro |
| 2013-06-23 | Fix the README examples. | Carlo Zancanaro |
| 2013-06-22 | Docstrings, one function call change, README update....In the compiler there was one call to `table-name` which should have been
`field-name`.
| Carlo Zancanaro |
| 2013-06-22 | Update project.clj | Carlo Zancanaro |
| 2013-06-21 | Docstrings, re-export from core better (with metadata) | Carlo Zancanaro |
| 2013-06-21 | Update the README a bit. | Carlo Zancanaro |
| 2013-06-21 | Return records on update, return just a count on delete (jdbc) | Carlo Zancanaro |
| 2013-06-21 | Add take/drop, move jdbc stuff, document default of postgres...Add take and drop functionality to the queries, so now you can use the take and
drop functions in a similar way to how they work on seqs in clojure.
Move jdbc interface stuff into clojure-sql.jdbc, so if you're using jdbc you
can include it yourself. (If you're not using jdbc then it shouldn't bother
you).
Given the default compilation target is actually postgres, document that.

| 2013-06-20 | Clean up, add an assertion. | Carlo Zancanaro |
| 2013-06-20 | Well, that didn't work. Whatever. | Carlo Zancanaro |
| 2013-06-20 | Fix updates, add "use-jdbc!" function to core. | Carlo Zancanaro |
| 2013-06-20 | Make core nicer, pass the "type" of query to executors | Carlo Zancanaro |
| 2013-06-20 | Clean up the query deref, make insert!, update! and delete! work | Carlo Zancanaro |
| 2013-06-20 | Fix a stupid null-pointer exception | Carlo Zancanaro |
| 2013-06-20 | Fix compiling of n-ary operators (0 & 1 args), add operator aliases...n-ary operators with no arguments would break everything (compiling to "()").
This should no longer be the case. Additionally, unary operators (ie. negation)
now compile properly in the one arg case.
Operator aliases allow us to change how we refer to things like the "~" regex
operator in postgresql. At the moment it's aliased as "$".
Additionally: booleans now compile to upper case.
| Carlo Zancanaro |
| 2013-06-20 | A few small changes/fixes to join behaviour, and code cleanup...Fix compilation of cross joins.
Remove the sort clauses on queries when they become subqueries in joins because
then the sorting means nothing (although when take/drop stuff is added the sort
will be relevant, so we'll see about that).
Favour the left side of a join, which is mostly only relevant for the outer
join case (and technically it's not quite right for full-outer joins, maybe,
but I'll get to that later).
| Carlo Zancanaro |
| 2013-06-17 | Rename sort-by, add grouping, refactor+fix some join stuff...`sort-by` is now called `sort`. This is just because I think it makes more
sense and nothing more.
Grouping has been added with `group` and `having`. They behave as you'd expect
from SQL, except that joining with a table which has a `group` or `having`
clause will move that query in as a subquery. I wasn't sure how else to ensure
their composition, so this way maintains the semantics (which is the most
important part) at the potential cost of some efficiency in performing the
query. I'm not sure that there exists a more general solution. I would assume
not.
The join stuff has been fixed a bit (some valid renames were rejected as
invalid) and standardised a bit (exceptions are now more similar). A bunch of
things have been added to the join stuff as a result of the above grouping
things, too. A bunch of changes all around, basically.
The compiler has also had a few small changes made to it, and has been enhanced
to support the grouping stuff.

| 2013-06-16 | Fix up some more join stuff, and a bit of sorting stuff. | Carlo Zancanaro |
| 2013-06-16 | Fix expression processing in the DSL, notably on vectors | Carlo Zancanaro |
| 2013-06-16 | Bring the DSL back up to previous features, fix the compiler...It should generally be usable at this point. It should generate the queries
correctly (including join order and stuff) and approximately properly do
things. The type of join stuff still hasn't been finished, but if the code were
left as-is it would still be possible to get whatever you wanted out of it, I
think.
Basically: lots of work has been done and we're approaching something more
usable.
| Carlo Zancanaro |
| 2013-06-13 | Starting a re-write of the DSL, to be followed by the compiler....Flip around field/table aliases, do joins a bit differently. They're my main
aims at the moment! I'll also add a preprocessor for the compiler to massage it
into a nicer form there.
I discovered that joins can be done with a pretty sweet syntax in SQL:
(tableA LEFT JOIN tableB) RIGHT JOIN tableC
This is pretty much perfect for my purposes.
Flipping alias maps just makes more sense and removes a whole bunch of
`flip-map` calls that would be unnecessary if the aliases were the other way
around. The user-facing side of the DSL will be left unchanged, though. The
user provides an `{old-name new-name}` map and internally we convert that into
`{new-name old-name}`. Like magic.
I'm also adding a bunch more tests. Hopefully that will make things more likely
to work for long periods of time.
Peace out!

| 2013-05-24 | Fix a bug in `resolve-fields`...The recursive calls to `resolve-fields` were not being made due to programmer
error. This has been fixed, so now the field resolution stuff should work
properly again.
This is really highlighting the need for better testing. Get on that!
