Unreleased Changes

The following changes have been committed to the master branch since the 1.0.12 release:

  • Fix #82 by adding clojure.java.data-based support for setting arbitrary properties on Connection and PreparedStatement objects, post-creation. Note: this uses the Java reflection API under the hood.
  • Adds next.jdbc.prepare/statement to create Statement objects with all the options available to prepare except :return-keys.
  • Update org.clojure/java.data to 0.1.5 (for property setting).

Stable Builds

  • 2019-12-11 -- 1.0.12

    • Address #81 by splitting the SQL-building functions out of next.jdbc.sql into next.jdbc.sql.builder.
    • Fix #80 by avoiding the auto-commit restore after a failed rollback in a failed transaction.
    • Address #78 by documenting the :connectionInitSql workaround for HikariCP/PostgreSQL and non-default schemas.

  • 2019-12-07 -- 1.0.11

    • Fix #76 by avoiding conversions on java.sql.Date and java.sql.Timestamp.
    • Add testing against Microsoft SQL Server (run tests with environment variables NEXT_JDBC_TEST_MSSQL=yes and MSSQL_SA_PASSWORD set to your local -- 127.0.0.1:1433 -- SQL Server sa user password; assumes that it can create and drop fruit and fruit_time tables in the model database).
    • Add testing against MySQL (run tests with environment variables NEXT_JDBC_TEST_MYSQL=yes and MYSQL_ROOT_PASSWORD set to your local -- 127.0.0.1:3306 -- MySQL root user password; assumes you have already created an empty database called clojure_test).
    • Bump several JDBC driver versions for up-to-date testing.
    • Minor documentation fixes.

  • 2019-11-14 -- 1.0.10

    • Fix #75 by adding support for java.sql.Statement to plan, execute!, and execute-one!.
    • Address #74 by making several small changes to satisfy Eastwood.
    • Fix #73 by providing a new, optional namespace next.jdbc.date-time that can be required if your database driver needs assistance converting java.util.Date (PostgreSQL!) or the Java Time types to SQL timestamp (or SQL date/time).
    • Fix link to All The Options in Migration from clojure.java.jdbc. PR #71 (@laurio).
    • Address #70 by adding CLOB & BLOB SQL Types to the Tips & Tricks section of Friendly SQL Functions and by adding next.jdbc.result-set/clob-column-reader and next.jdbc.result-set/clob->string helper to make it easier to deal with CLOB column data.
    • Clarify what execute! and execute-one! produce when the result set is empty ([] and nil respectively, and there are now tests for this). Similarly for find-by-keys and get-by-id.
    • Add MS SQL Server section to Tips & Tricks to note that it returns an empty string for table names by default (so table-qualified column names are not available). Using the :result-type (scroll) and :concurrency options will cause table names to be returned.
    • Clarify that Friendly SQL Functions are deliberately simple (hint: they will not be enhanced or expanded -- use plan, execute!, and execute-one! instead, with a DSL library if you want!).
    • Improve migration docs: explicitly recommend the use of a datasource for code that needs to work with both clojure.java.jdbc and next.jdbc; add caveats about column name conflicts (in several places).
    • Improve datafy/nav documentation around :schema.
    • Update org.clojure/java.data to "0.1.4" (0.1.2 fixes a number of reflection warnings).

  • 2019-10-11 -- 1.0.9

    • Address #69 by trying to clarify when to use execute-one! vs execute! vs plan.
    • Address #68 by clarifying that builder functions do not affect the "fake result set" containing :next.jdbc/update-count.
    • Fix #67 by adding :jdbcUrl version spec.
    • Add next.jdbc.optional/as-maps-adapter to provide a way to override the default result set reading behavior of using .getObject when omitting SQL NULL values from result set maps.

  • 2019-09-27 -- 1.0.8

    • Fix #66 by adding support for a db-spec hash map format containing a :jdbcUrl key (consistent with ->pool) so that you can create a datasource from a JDBC URL string and additional options.
    • Address #65 by adding a HugSQL "quick start" to the Friendly SQL Functions section of the docs.
    • Add next.jdbc.specs/unstrument. PR #64 (@gerred).
    • Address #63 by improving documentation around qualified column names and :qualifier (clojure.java.jdbc) migration, with a specific caveat about Oracle not fully supporting .getTableName().

  • 2019-09-09 -- 1.0.7

    • Address #60 by supporting simpler schema entry formats: :table/column is equivalent to the old [:table :column :one] and [:table/column] is equivalent to the old [:table :column :many]. The older formats will continue to be supported but should be considered deprecated. PR #62 (@seancorfield).
    • Added test for using ANY(?) and arrays in PostgreSQL for IN (?,,,?) style queries. Added a Tips & Tricks section to Friendly SQL Functions with database-specific suggestions, that starts with this one.
    • Improved documentation in several areas.

  • 2019-08-24 -- 1.0.6

    • Improved documentation around insert-multi! and execute-batch! (addresses #57).
    • Fix #54 by improving documentation around data type conversions (and the ReadableColumn and SettableParameter protocols).
    • Fix #52 by using a US-locale function in the "lower" result set builders to avoid unexpected character changes in column names in locales such as Turkish. If you want the locale-sensitive behavior, pass clojure.string/lower-case into one of the "modified" result set builders.
    • Add next.jdbc.result-set/as-maps-adapter and next.jdbc.result-set/as-arrays-adapter to provide a way to override the default result set reading behavior of using .getObject.
    • Update org.clojure/test.check to "0.10.0".

  • 2019-08-05 -- 1.0.5

    • Fix #51 by implementing IPersistentMap fully for the "mapified" result set inside plan. This adds support for dissoc and cons (which will both realize a row), count (which returns the column count but does not realize a row), empty (returns an empty hash map without realizing a row), etc.
    • Improved documentation around connection pooling (HikariCP caveats).

  • 2019-07-24 -- 1.0.4

    • Fix #50 by adding machinery to test against (embedded) PostgreSQL!
    • Improved documentation for connection pooled datasources (including adding a Component example); clarified the recommendations for globally overriding default options (write a wrapper namespace that suits your usage).
    • Note: this release is primarily to fix the cljdoc.org documentation via repackaging the JAR file.

  • 2019-07-23 -- 1.0.3

    • Fix #48 by adding next.jdbc.connection/->pool and documenting how to use HikariCP and c3p0 in the Getting Started docs (as well as adding tests for both libraries).
    • Documentation improvements, including examples of extending ReadableColumn and SettableParameter.
    • Updated test dependencies (testing against more recent versions of several drivers).

  • 2019-07-15 -- 1.0.2

    • Fix #47 by refactoring database specs to be a single hash map instead of pouring multiple maps into one.
    • Fix #46 by allowing :host to be :none which tells next.jdbc to omit the host/port section of the JDBC URL, so that local databases can be used with :dbtype/:classname for database types that next.jdbc does not know. Also added :dbname-separator and :host-prefix to the "db-spec" to allow fine-grained control over how the JDBC URL is assembled.
    • Fix #45 by adding TimesTen driver support.
    • Fix #44 so that insert-multi! with an empty rows vector returns [].
    • Fix #43 by adjusting the spec for insert-multi! to "require less" of the cols and rows arguments.
    • Fix #42 by adding specs for execute-batch! and set-parameters in next.jdbc.prepare.
    • Fix #41 by improving docstrings and documentation, especially around prepared statement handling.
    • Fix #40 by adding next.jdbc.prepare/execute-batch!.
    • Added asserts in next.jdbc.sql as more informative errors for cases that would generate SQL exceptions (from malformed SQL).
    • Added spec for :order-by to reflect what is actually permitted.
    • Expose next.jdbc.connect/dbtypes as a table of known database types and aliases, along with their class name(s), port, and other JDBC string components.

  • 2019-07-03 -- 1.0.1

    • Fix #37 by adjusting the spec for with-transaction to "require less" of the :binding vector.
    • Fix #36 by adding type hint in with-transaction macro.
    • Fix #35 by explaining the database-specific options needed to ensure insert-multi! performs a single, batched operation.
    • Fix #34 by explaining save points (in the Transactions documentation).
    • Fix #33 by updating the spec for the example key-map in find-by-keys, update!, and delete! to reflect that you cannot pass an empty map to these functions (and added tests to ensure the calls fail with spec errors).

  • 2019-06-12 -- 1.0.0 "gold"

    • Address #31 by making reify'd objects produce a more informative string representation if they are printed (e.g., misusing plan by not reducing it or not mapping an operation over the rows).
    • Fix #26 by exposing next.jdbc.result-set/datafiable-result-set so that various java.sql.DatabaseMetaData methods that return result metadata information in ResultSets can be easily turned into a fully realized result set.

  • 2019-06-04 -- 1.0.0-rc1:

    • Fix #24 by adding return type hints to next.jdbc functions.
    • Fix #22 by adding next.jdbc.optional with six map builders that omit NULL columns from the row hash maps.
    • Documentation improvements (#27, #28, and #29), including changing "connectable" to "transactable" for the transact function and the with-transaction macro (for consistency with the name of the underlying protocol).
    • Fix #30 by adding modified variants of column name functions and builders. The lower variants have been rewritten in terms of these new modified variants. This adds :label-fn and :qualifier-fn options that mirror :column-fn and :table-fn for row builders.

  • 2019-05-24 -- 1.0.0-beta1:

    • Set up CircleCI testing (just local DBs for now).
    • Address #21 by adding next.jdbc.specs and documenting basic usage.
    • Fix #19 by caching loaded database driver classes.
    • Address #16 by renaming reducible! to plan (BREAKING CHANGE!).
    • Address #3 by deciding to maintain this library outside Clojure Contrib.
