Sequel is a lightweight database access toolkit for Ruby.
* Sequel provides thread safety, connection pooling and a concise
DSL for constructing SQL queries and table schemas.
* Sequel includes a comprehensive ORM layer for mapping records to
Ruby objects and handling associated records.
* Sequel supports advanced database features such as prepared
statements, bound variables, stored procedures, savepoints,
two-phase commit, transaction isolation, master/slave
configurations, and database sharding.
* Sequel currently has adapters for ADO, Amalgalite, CUBRID,
DataObjects, DB2, DBI, Firebird, IBM_DB, Informix, JDBC, MySQL,
Mysql2, ODBC, OpenBase, Oracle, PostgreSQL, SQLAnywhere, SQLite3,
Swift, and TinyTDS.
Sequel 4.5.0 has been released!
= New Features
* An mssql_optimistic_locking plugin has been added. This is similar
to the regular optimistic_locking plugin, but instead of using an
integer lock column, it uses a timestamp/rowversion lock column.
* Database#create_table with the :temp=>true option on PostgreSQL now
supports an :on_commit option. This option can be set to :drop or
:delete_rows to either drop or empty the temporary table on
transaction commit.
= Other Improvements
* Dataset#insert no longer errors on PostgreSQL if the related table
is a placeholder literal string.
* Unique constraints are now copied when emulating alter_table
operations on SQLite.
* Clob column values are no longer returned as SQL::Blob instances
by the db2 and ibmdb adapters unless use_clob_as_blob is true.
* SQL::Blob objects now work correctly as prepared statement
arguments in the jdbc/db2 adapter if use_clob_as_blob is false.
= Backwards Compatibility
* The Model.primary_key array for models with composite keys is now
frozen.
* On DB2, use_clob_as_blob now defaults to false instead of true.
* Sequel no longer uses RubyForge. The Sequel website is now located
at http://sequel.jeremyevans.net.
