honeysql/CHANGELOG.md

# Changes

* 2.0.0-alpha3 in progress
  * Fix #305 by supporting more complex join clauses.
  * Add tests to confirm #299 does not affect v2.
  * Confirm the whole of the [nilenso/honeysql-postgres](https://github.com/nilenso/honeysql-postgres) is implemented out-of-the-box (#293).
  * Reconcile `where` behavior with recent 1.0 changes (porting #283 to v2).
  * Fix #277 by adding `:join-by`/`join-by` so that you can have multiple `JOIN`'s in a specific order.

* 2.0.0-alpha2 (for early testing)
  * Since Alpha 1, a lot more documentation has been written and docstrings have been added to most functions in `honey.sql.helpers`.
  * Numerous small improvements have been made to clauses and helpers around insert/upsert.
* 2.0.0-alpha1 (for early testing)
  * This is a complete rewrite/simplification of HoneySQL that provides just two namespaces:
    * `honey.sql` -- this is the primary API via the `format` function as well as the various extension points.
    * `honey.sql.helpers` -- provides a helper function for every piece of the DSL that is supported out-of-the-box.
  * The coordinates for HoneySQL 2.0 are `seancorfield/honeysql` so it can be added to a project that already uses HoneySQL 1.0 without any conflicts, making it easier to migrate piecemeal from 1.0 to 2.0.

# HoneySQL pre-2.x Changes

* 1.0.461 -- 2021-02-22
  * **Fix #299 potential SQL injection vulnerability.**
  * Fix/Improve `merge-where` (and `merge-having`) behavior. #282 via #283 (@camsaul)

* 1.0.444 -- 2020-05-29
  * Fix #259 so column names are always unqualified in inserts. (@jrdoane)
  * Fix #257 by adding support for `cross-join` / `merge-cross-join` / `:cross-join`. (@dcj)
  * Switch dev/test pipeline to use CLI/`deps.edn` instead of Leiningen. Also add CI vi both CircleCI and GitHub Actions.
  * Switch to MAJOR.MINOR.COMMITS versioning.
  * Remove macrovich dependency as this is no longer needed with modern ClojureScript.
  * Add mention of `next.jdbc` everywhere `clojure.java.jdbc` was mentioned.

* 0.9.10 -- 2020-03-06
  * Fix #254 #255 by adding support for `except`. (@ted-coakley-otm)
  * Fix #253 properly by supporting `false` as well. (@ted-coakley-otm)
  * Add cljs testing to `deps.edn`, also multi-version clj testing and new `readme` testing.

* 0.9.9 -- 2020-03-02
  * Fix #253 by supporting non-sequential join expressions.

* 0.9.8 -- 2019-09-07
  * Fix #249 by adding `honeysql.format/*namespace-as-table?*` and `:namespace-as-table?` option to `format`. (@seancorfield)

* 0.9.7 -- 2019-09-07
  * Fix #248 by treating alias as "not a subquery" when generating SQL for it. (@seancorfield)
  * Fix #247 by reverting #132 / #131 so the default behavior is friendlier for namespace-qualified keywords used for table and column names, but adds `honeysql.format/*allow-namespaced-names?*` to restore the previous behavior. A `:allow-namespaced-names?` option has been adding to `format` to set this more easily. (@seancorfield)
  * Fix #235 by adding `set0` (`:set0`) and `set1` (`:set1`) variants of `sset` (`:set`) to support different placements of `SET` (before `FROM` or after `JOIN` respectively) that different databases require. See also #200. (@seancorfield)
  * Fix #162 by adding `composite`/`:composite` constructor for values. (@seancorfield)
  * Fix #139 by checking arguments to `columns`/`merge-columns` and throwing an exception if a single collection is supplied (instead of varargs). (@seancorfield)
  * Fix #128 by adding `truncate` support. (@seancorfield)
  * Fix #99 by adding a note to the first use of `select` in the README that column names can be keywords or symbols but not strings. (@seancorfield)

* 0.9.6 -- 2019-09-24
  * Filter `nil` conditions out of `where`/`merge-where`. Fix #246. (@seancorfield)
  * Fix reflection warning introduced in 0.9.5 (via PR #237).

* 0.9.5 -- 2019-09-07
  * Support JDK11 (update Midje). PR #238. (@camsaul)
  * Support Turkish user.language. PR #237. (@camsaul)
  * `format-predicate` now accepts `parameterizer` as a named argument (default `:jdbc`) to match `format`. PR #234. (@glittershark)

* 0.9.4 -- 2018-10-01
  * `#sql/inline nil` should produce `NULL`. Fix #221. (@seancorfield)
  * `#sql/inline :kw` should produce `"kw"`. Fix #224 via PR #225. (@vincent-dm) Note: this introduces a new protocol, `Inlinable`, which controls inline value rendering, and changes the behavior of `#sql/inline :foo/bar` to produce just `"bar"` (where it was probably invalid SQL before).
  * Alias expressions `[:col :alias]` are now checked to have exactly two elements. Fix #226. (@seancorfield)
  * Allow `where` and `merge-where` to be given no predicates. Fix #228 and PR #230. (@seancorfield, @arichiardi)
  * `as` alias is no longer split during quoting. Fix #221 and PR #231. (@gws)
