What?
Clojure contrib wrapper for JDBC
https://github.com/clojure/java.jdbc
Release?
0.7.0 Alpha 1 (previous release was 0.6.2 Alpha 3)
[org.clojure/java.jdbc “0.7.0-alpha1”]
** potentially breaking changes **
Summary?
• Minor enhancements but version bump is because two naming strategy functions
have signature changes (see below).
• Option passing is now consistent across all functions (and all call chains).
• New get-isolation-level function.
• New read-columns option.
• Expanded clojure.spec coverage.
Details?
• 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 now 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.
