Changes in 0.7.12

• Make the protocols ISQLValue, ISQLParameter, and IResultSetReadColumn extensible via metadata.

Changes in 0.7.11

• Address edge case in transaction rollback failure JDBC-179.

Changes in 0.7.10

• Use a US-locale lower-case function to avoid problems in certain locales (e.g., Turkish). A similar issue has been fixed recently in both HoneySQL and next.jdbc.
• Clean up db-spec options that are passed to the JDBC connection manager as properties JDBC-178.
• Relax restriction on create-table-ddl column specs to allow numbers (as well as keywords and strings) JDBC-177.

Changes in 0.7.9

• Fix behavior of multi-inserts when database does not support generated keys JDBC-176.
• Added highly experimental support for datafy/nav (in clojure.java.jdbc.datafy namespace). This includes a convention-based approach to foreign keys with some assistance from a :schema option. This is subject to change and is provided mostly for informational purposes, as an example of the new functionality in Clojure 1.10. This includes a fix for the conventions from JDBC-175.
• Add note about rewriting batched operations to insert-multi! for some drivers JDBC-174.
• Support Oracle SID style URLs (dbtype can be oracle:sid which maps to oracle:thin and uses : as the separator before the dbname value) JDBC-173.

Changes in 0.7.8

• Support multiple JDBC driver class names (MySQL introduced a new driver class name with its 6.x connector) JDBC-172.
• Allow with-db-connection and with-db-metadata to nest JDBC-171.

Changes in 0.7.7

• Support :as-arrays?, :result-set-fn, and :row-fn in operations that return generated keys as a result set (execute!, insert!, and insert-multi!) JDBC-169.
• get-connection provides much better feedback if you accidentally call a function that expects a db-spec but pass a java.sql.Connection object instead (which is only required for prepare-statement).

Changes in 0.7.6

• execute! now supports :return-keys as a vector of column names, rather than just a simple Boolean value, for drivers that support that JDBC-166.
• Add built-in support for H2 in-memory database (:dbtype "h2:mem").
• Add missing spec for db-spec being a java.net.URI object.
• Fix add-connection handling of string db-spec (becomes :connection-uri, not :connection-string).
• Fix specs for with-db-* functions, to support options in the binding form JDBC-165.
• Update tests so they work properly with string db-spec test databases.
• Ensure no reflection warnings are present.
• Switched local test infrastructure over to CLI and deps.edn (from Leiningen) as an example of multi-version testing without a "build tool".

Changes in 0.7.5

• Add support for :return-keys in execute! and :multi? in db-do-prepared-return-keys JDBC-163.

Changes in 0.7.4

• Improved discoverability of other java.jdbc documentation JDBC-160.
• Optional specs updated with :keywordize? and :connection-uri changes from 0.7.2 and 0.7.3 releases.
• Performance improvements, primarily in query and reducible-query.
• Experimental :raw? result set handling in reducible-query.
• modify-connection is more robust in the face of null connections and bad option values.

Changes in 0.7.3

• Added :keywordize? option alongside :identifiers that defaults to true but can be set to false to opt-out of converting identifiers to keywords (so column names etc will only be processed by the function passed as :identifiers) JDBC-159.
• If an exception occurs during a transaction, and then rollback fails with another exception, both exceptions will now be combined into an ex-info. Previously the rollback exception obscured the transaction exception JDBC-158.

Changes in 0.7.2

• connection-uri was incorrectly spec'd as a java.net.URI but should be string? JDBC-156.
• Allow for :user and :password to be passed with :connection-uri, so credentials can be omitted from the connection string.
• Clarified docstring for get-connection to show where :user and :password can be passed.

Changes in 0.7.1

• Connection strings with empty values were not parsed correctly JDBC-155.

Changes in 0.7.0

• :conditional? option for create-table-ddl and drop-table-ddl to provide for existence check (or a function to manipulate the generated DDL).
• Add better support for Oracle connections (default port to 1521, support :dbtype "oracle" -- as "oracle:thin" -- and :dbtype "oracle:oci", with @ instead of // before host).

Changes in 0.7.0-beta5

• get-connection now accepts an opts map with :auto-commit? and :read-only? options. If present, the appropriate methods will be called on the connection obtained. These options are valid in any function call that may call get-connection under the hood. This should allow for streaming results in a query for most databases JDBC-153.
• Additional validation of options is performed in prepared-statement to avoid silently ignoring invalid combinations of :concurrency, :cursors, :result-type, and :return-keys.

Changes in 0.7.0-beta4

• opts are now correctly passed from reducible-query to db-query-with-resultset.
• Updated the ::query-options spec to make it clear that ::prepare-options are also acceptable there.

Changes in 0.7.0-beta3

• Reflection warnings removed in reducible-result-set JDBC-152.

Changes in 0.7.0-beta2

• Support for Clojure 1.6.0 and earlier has been dropped -- breaking change.
• Or, put another way, clojure.java.jdbc now requires Clojure 1.7 or later!
• All public functions now have specs in the optional clojure.java.jdbc.spec namespace (requires clojure.spec.alpha).
• reducible-query and reducible-result-set use IReduce and correctly support the no-init arity of reduce by using the first row of the ResultSet, if present, as the (missing) init value, and only calling f with no arguments if the ResultSet is empty. The init arity of reduce only ever calls f with two arguments.

Changes in 0.7.0-beta1

• Support for Clojure 1.4.0 has been dropped -- breaking change.
• Optional spec support now uses clojure.spec.alpha.
• reducible-query accepts a db-spec and a SQL/parameters vector and returns a reducible (IReduce on Clojure 1.7 or later; CollReduce on Clojure 1.5/1.6): when reduced, it runs the query, obtains a reducible result set, and then reduces that. A reducible query will run the query each time it is reduced. The helper function reducible-result-set is public: it accepts a ResultSet and produces a reducible that offers a single pass reduce over the rows. Both functions honor reduced values to short-circuit the process JDBC-99.

Changes in 0.7.0-alpha3

• classname is now accepted with dbtype / dbname so you can easily specify a JDBC driver class name for a database type that is not known JDBC-151.
• redshift has been added as a dbtype with com.amazon.redshift.jdbc.Driver as the driver name.

Changes in 0.7.0-alpha2

• pgsql and the Impossibl PostgresSQL 'NG' driver are now supported (note that :max-rows does not work with this driver!); also, providing unknown dbtype or subprotocol in a db-spec should now throw a better exception JDBC-150.
• quoted now accepts keywords for database / dialect (:ansi (including PostgresSQL), :mysql, :oracle, :sqlserver -- these match the keywords used in HoneySQL which is the recommended third party SQL DSL for java.jdbc) JDBC-149.
• Reorder get-connection clauses to make it easier to combine keys in a db-spec JDBC-148.
• Force load DriverManager before classForName call on drivers to avoid potential race condition on initialization JDBC-145.

Changes in 0.7.0-alpha1 -- potentially breaking changes

• The signatures of as-sql-name and quoted have changed slightly: the former no longer has the curried (single argument) version, and the latter no longer has the two argument version. This change came out of a discussion on Slack which indicated curried functions are non-idiomatic. If you relied on the curried version of as-sql-name, you will not need to use partial. If you relied on the two argument version of quoted, you will need to add an extra ( ) for the one argument call. I'd be fairly surprised if anyone is using as-sql-name at all since it is really an implementation detail. I'd also be surprised if anyone was using the two argument version of quoted since the natural usage is :entities (quoted [\[ \]]) to create a naming strategy (that provides SQL entity quoting).
• Clarified that insert-multi! with a sequence of row maps may be substantially slower than with a sequence of row value vectors (the former performs an insert for each row, the latter performs a single insert for all the data together) JDBC-147.
• All options are passed through all function calls, expanding the range of options you can pass into high-level functions such as insert! and update! JDBC-144.
• Added get-isolation-level to return the current transaction's isolation level, if any JDBC-141.
• Added support for read-columns option to allow more flexible customization of reading column values from a result set (particularly in a multi-database application). Also expands set-parameters support to options (previously it was just part of the db-spec) JDBC-137.
• Expanded optional clojure.spec coverage to almost the whole library API.

Changes in 0.6.2-alpha3

• Fixed bad interaction between :qualifier and existing :identifiers functionality JDBC-140.
• Updated the README and docstrings to reflect that :dbtype is the easiest / preferred way to write db-spec maps JDBC-139.
• Fixed postgres / postgresql alias support JDBC-138. This also adds aliases for mssql (sqlserver), jtds (jtds:sqlserver), oracle (oracle:thin), and hsql (hsqldb).

Changes in 0.6.2-alpha2

• Updates to clojure.spec support to work properly with Clojure 1.9.0 Alpha 10.

Changes in 0.6.2-alpha1

• Experimental support for clojure.spec via the new clojure.java.jdbc.spec namespace. Requires Clojure 1.9.0 Alpha 8 (or later).
• All options to all functions can now have defaults within the db-spec itself JDBC-136.
• query (and by extension find-by-keys and get-by-id) now support :explain? and :explain-fn options to help support basic performance analysis JDBC-135.
• insert! and insert-multi! now respect :identifiers and :qualifier because inserting rows on PostgreSQL returns full rows, not just the newly inserted keys JDBC-134.
• In addition to the :identifiers option, you can now use :qualifier to specify a namespace qualifier (string) to be used when constructing keywords from SQL column names JDBC-133.

Changes in 0.6.1

• insert! and insert-multi! now default :transaction? to true (as they should have done in 0.6.0!) JDBC-128. These two functions also have improved docstrings to clarify the difference in behavior between inserting rows as maps compared to inserting rows as a series of column values.
• PostgreSQL support has been improved: java.jdbc is now tested against PostgreSQL locally (as well as SQLite, Apache Derby, HSQLDB, H2, MySQL, MS SQL Server (both MS Type 4 driver and jTDS driver). JDBC-127 and JDBC-129.

Changes in 0.6.0

• find-by-keys now correctly handles nil values JDBC-126.
• find-by-keys calls seq on :order-by to treat [] as no ORDER BY clause.

Changes in 0.6.0-rc2

• db-query-with-resultset now accepts an options map and passes it to prepare-statement JDBC-125.
  • Passing the prepare-statement options map as the first element of the [sql & params] vector is no longer supported and will throw an IllegalArgumentException. It was always very poorly documented and almost never used, as far as I can tell.
• db-query-with-resultset no longer requires the sql-params argument to be a vector: a sequence is acceptable. This is in line with other functions that accept a sequence.
• db-query-with-resultset now accepts a bare SQL string or PreparedStatement as the sql-params argument, when there are no parameters needed. This is in line with other functions that accept SQL or a PreparedStatement.
• query's options map now is passed to db-query-with-resultset and thus can contain options to be used to construct the PreparedStatement JDBC-125.
• find-by-keys now accepts an :order-by option that specifies a sequence of orderings; an ordering is either a column (to sort ascending) or a map from column name to direct (:asc or :desc).

Changes in 0.6.0-rc1

• Adds get-by-id and find-by-keys convenience functions (these were easy to add after the API changes in 0.6.0 and we rely very heavily on them at World Singles so putting them in the core for everyone seemed reasonable).
• REMINDER: ALL DEPRECATED FUNCTIONALITY HAS BEEN REMOVED! JDBC-118.
  • See alpha2 / alpha1 below for more details.

Changes in 0.6.0-alpha2

• ALL DEPRECATED FUNCTIONALITY HAS BEEN REMOVED! JDBC-118.
  • This removes deprecated functionality from db-do-commands and db-do-prepared* which should have been removed in Alpha 1.
• Ensures SQL / params are actually vectors prior to destructuring (this addresses an interop edge case from other languages) JDBC-124.
• Fix typo in insert-multi! argument validation exception JDBC-123.

Changes in 0.6.0-alpha1

• (ALMOST) ALL DEPRECATED FUNCTIONALITY HAS BEEN REMOVED! JDBC-118.
  • See changes described in versions 0.5.5 through 0.5.8 for what was deprecated
  • Use version 0.5.8 as a bridge to identify any deprecated API calls on which your code relies!
  • db-transaction (deprecated in version 0.3.0) has been removed
  • The java.jdbc.deprecated namespace has been removed

Changes in 0.5.8

• db-do-commands now expects multiple commands to be be wrapped in a vector JDBC-122. The single command form is unchanged (but may be wrapped in a vector). Calling db-do-commands with multiple commands (not wrapped in a single vector) will produce a "DEPRECATED" warning printed to the console.
• db-do-prepared and db-do-prepared-return-keys now expect to receive a db-spec, an optional transaction? boolean, a sql-params argument, and an optional options map. sql-params is a vector containing a SQL string or PreparedStatement followed by parameters -- like other APIs in this library. In addition, like the :multi? true version of execute!, db-do-prepared can accept a vector that has parameter groups: multiple vectors containing groups of parameter values JDBC-122. Calling db-do-prepared with unrolled arguments -- the SQL string / statement followed by parameter groups -- is deprecated and will produce "DEPRECATED" warnings printed to the console.

Changes in 0.5.7

• (insert! db table [:col] ["val"] {}) syntax, introduced in 0.5.6, threw an exception JDBC-121.

Changes in 0.5.6

• create-table-ddl now expects the column specs to be wrapped in a single vector and no longer needs the :options delimiter to specify the options map JDBC-120. If column specs are not wrapped in a vector, you will get a "DEPRECATED" warning printed to the console.
• insert! now supports only single row insertion; multi-row insertion is deprecated. insert-multi! has been added for multi-row insertion. :options is no longer needed as a delimiter for the options map JDBC-119. If insert! is called with multiple rows, or :options is specified, you will get a "DEPRECATED" warning printed to the console.
• NOTE: all deprecated functionality will go away in version 0.6.0!

Changes in 0.5.5

• Allow options map in all calls that previously took optional keyword arguments JDBC-117. The unrolled keyword argument forms of call are deprecated -- and print a "DEPRECATED" message to the console! -- and will go away in 0.6.0.

Changes in 0.5.0

• Allow PreparedStatement in db-do-prepared-return-keys JDBC-115.
• Remove exception wrapping JDBC-114.
• Drop Clojure 1.3 compatibility.

Changes in 0.4.2

• Remove redundant type hints JDBC-113 - Michael Blume.
• Avoid reflection on .prepareStatement JDBC-112 - Michael Blume.
• Add metadata-query macro to make metadata query / results easier to work with for JDBC-107.
• prepare-statement :return-keys may now be a vector of (auto-generated) column names to return, in addition to just being truthy or falsey. This allows keys to be returned for more databases. JDBC-104.
• Officially support H2 (and test against it) to support JDBC-91 and clarify docstrings to improve debugging driver-specific restrictions on SQL.

Changes in 0.4.0 / 0.4.1

• db-do-prepared now allows transaction? to be omitted when a PreparedStatement is passed as the second argument JDBC-111 - Stefan Kamphausen.
• Nested transaction checks isolation level is the same JDBC-110 - Donald Ball.
• Default PostgreSQL port; Support more dbtype/dbname variants JDBC-109.
• Drop Clojure 1.2 compatibility.

Changes in 0.3.7

• Bump all driver versions in project.clj and re-test.
• Remove duplicate count calls in insert-sql JDBC-108 - Earl St Sauver.

Changes in 0.3.2

• Add nil protocol implementation to ISQLParameter.

Changes in 0.3.1 (broken)

• Provide better protocol for setting parameters in prepared statements JDBC-86.
• Fix parens in two deprecated tests JDBC-85.
• Made create-table-ddl less aggressive about applying as-sql-name so only first name in a column spec is affected.

Changes in 0.3.0

• Rename recently introduced test to ensure unique names JDBC-83.
• Rename unused arguments in protocol implementation to support Android JDBC-82.
• Correctly handle empty param group sequence in execute! (which only seemed to affect SQLite) JDBC-65.

Changes in 0.3.0-rc1

• Deprecate db-transaction (new in 0.3.0) in favor of with-db-transaction JDBC-81.
• Add with-db-metadata macro and metadata-result function to make it easier to work with SQL metadata JDBC-80.
• Add with-db-connection macro to make it easier to run groups of operations against a single open connection JDBC-79.
• Add ISQLValue protocol to make it easier to support custom SQL types for parameters in SQL statements JDBC-77.
• Add support for :isolation in with-db-transaction JDBC-75.
• Add :user as an alias for :username for DataSource connections JDBC-74.

Changes in 0.3.0-beta2

• The DSL namespaces introduced in 0.3.0-alpha1 have been retired - see java-jdbc/dsl for a migration path if you wish to continue using the DSL (although it is recommended you switch to another, more expressive DSL).
• The older API (0.2.3) which was deprecated in earlier 0.3.0 builds has moved to clojure.java.jdbc.deprecated to help streamline the API for 0.3.0 and clean up the documentation.

Changes in 0.3.0-beta1

• query as-arrays? now allows you to leverage lazy result fetching JDBC-72.
• "h2" is recognized as a protocol shorthand for org.h2.Driver
• Tests no longer use :1 literal JDBC-71.

  • it is the user's responsibility to handle this if you're using such a database!

Changes in 0.0.4:

• Fix JDBC-2 by allowing :table-spec {string} at the end of create-table arguments: (sql/create-table :foo [:col1 "int"] ["col2" :int] :table-spec "ENGINE=MyISAM")
