Sequel 4.37.0 has been released!
= New Features
* Database#values has been added on SQLite#3.8.3+, operating similarly
to the support on PostgreSQL:
DB.values([[1, 2], [3, 4]]).select_map([:column1, :column2])
# => [[1, 2], [3, 4]]
* Regular expressions in dataset filters are now supported on Oracle
10g+:
DB[:t].where(:c=>/re/)
# SELECT * FROM "T" WHERE REGEXP_LIKE("C",'re')
= Other Improvements
* Sequel now supports the use of native prepared statements and bound
variables in the mysql2 adapter, when mysql2 0.4+ is used.
Previously, the mysql2 adapter supported database prepared
statements, but variables were always literalized. That is still
supported when mysql2 <0.4 is used.
* The connection pool now removes connections if it detects a
disconnect error that is not raised as a
Sequel::DatabaseDisconnectError. Such exceptions are reraised
without converted them to Sequel::DatabaseDisconnectError, but the
related connection is now removed from the pool.
* The reversible migration support now handles add_constraint with an
options hash as the first argument.
* ASTTransformer now handles Sequel.extract, allowing Dataset#qualify
and other uses of ASTTransformer to work with such values.
* The create_view :columns option is now suppported on SQLite 3.9.0+.
* An additional disconnect error is now recognized in the postgres
adapter.
* A frozen string literal issue has been fixed when multiple different
database connection approaches have failed in the jdbc adapter.
= Backwards Compatibility
* External database adapters need to make sure that
Database#database_error_classes returns a valid result if called
during Database#initialize. If you have an external adapter where
one of the error classes depends on an argument given when
connecting (such as the connection string), you may have to make
some changes.
Thanks,
Jeremy
