* 2.2.20 * (September 10th, 2009)
* Implement a new remove_default_constraint method that uses sp_helpconstraint [Ken Collins]
* Use a lazy match in add_order_by_for_association_limiting! to allow sub selects to be used. Resolves
ticket #11.
* Add default rake task back for testing. Runs the namespaced sqlserver:test_sqlserver_odbc.
Resolves ticket #10 [Ken Collins]
* Default value detection in column_definitions is kinder to badly formatted, or long winded user
defined functions, for default values. Resolves ticket #8 [Ken Collins]
* Make sure bigint SQL Server data type can be used and converted back to Bignum as expected. [Ken Collins]
* 2.2.19 * (June 19th, 2009)
* Leave quoted column names as is. Resolves ticket #36 [Vince Puzzella]
* Changing add_limit! in ActiveRecord::Base for SQLServer so that it passes through any scoped :order
parameters. Resolves ticket #35 [Murray Steele]
* 2.2.18 * (June 5th, 2009)
* Column reflection on table name rescues LoadError and a few others. Resolves tickets #25 & #33 [Ken Collins]
* Added 2008 support. Resolves ticket #32 [Ken Collins]
* 2.2.17 * (May 14th, 2009)
* Add simplified type recognition for varchar(max) and nvarchar(max) under SQL Server 2005 to be a
:text type. This ensures schema dumper does the right thing. Fixes ticket #30. [Ken Collins]
* Tested ruby 1.9, ruby-odbc 0.9996, and DBI 0.4.1. Also added correct support for UTF-8 character
encoding going in and out of the DB. See before gist http://gist.github.com/111709 and after gist
http://gist.github.com/111719 [Ken Collins]
* 2.2.16 * (April 21st, 2009)
* Make add_limit_offset! only add locking hints (for tally) when the :lock option is present. Added tests
to make sure tally SQL is augmented correctly and tests to make sure that add_lock! is doing what it needs
for deep sub selects in paginated results. [Ken Collins]
* Add auto reconnect support utilizing a new #with_auto_reconnect block. By default each query run through
the adapter will automatically reconnect at standard intervals, logging attempts along the way, till success
or the original exception bubbles up. See docs for more details. Resolves ticket #18 [Ken Collins]
* Update internal helper method #orders_and_dirs_set to cope with an order clause like "description desc". This
resolves ticket #26 [Ken Collins]
* Provide support for running queries at different isolation levels using #run_with_isolation_level method
that can take a block or not. Also implement a #user_options method that reflects on the current user
session values. Resolves #20 [Murray Steele]
* 2.2.15 * (March 23rd, 2009)
* Better add_lock! method that can add the lock to just about all the elements in the statement. This
could be eager loaded associations, joins, etc. Done so that paginated results can easily add lock
options for performance. Note, the tally count in add_limit_offset! use "WITH (NOLOCK)" explicitly
as it can not hurt and is needed. [Ken Collins]
* 2.2.14 * (March 17th, 2009)
* Rails2.3 - Back passing tests on 2.2 work. Includes: (1) Created new test helpers that check ActiveRecord
version strings so we can conditionally run 2.2 and 2.3 tests. (2) Making TransactionTestSqlserver use Ship vs
Bird model. Also made it conditional run a few blocks for different versions of ActiveRecord. (3) Previous
JoinDependency#aliased_table_name_for is now only patched in ActiveRecord equal or greater than 2.3. [Ken Collins]
* Rails2.3 - Implement new savepoint support [Ken Collins]
http://rails.lighthouseapp.com/projects/8994/tickets/383
http://www.codeproject.com/KB/database/sqlservertransactions.aspx
* Rails2.3 - Coerce NestedScopingTest#test_merged_scoped_find to use correct regexp for adapter. [Ken Collins]
* Rails2.3 - Implement a custom ActiveRecord::Associations::ClassMethods::JoinDependency::JoinAssociation#aliased_table_name_for
method that uses a Regexp.escape so that table/column quoting does not get ignored. [Ken Collins]
* Rails2.3 - Implement #outside_transaction? and a new transaction test case to test some SQL Server
basic support while implementing this method. Future home of some savepoint tests too. [Ken Collins]
* Rails2.3 - Coerced tests that ensure hash conditions on referenced tables are considered when eager
loading with limit/offset. Information on these changes and the ticket in rails are.

http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1404-conditions_tables-doesnt-understand-condition-hashes
* Rails2.3 - Add coerced tests for true/false attributes in selects use SQL Server case statement. [Ken Collins]
* Making sure that smalldatetime types are OK to use. Also fixed a bug in the #view_information method that
checks to see if a view definition is equal to 4000 chars, meaning that it is most likely truncated and
needs to use the backup method of sp_helptext to get it's view definition. [Ken Collins]
* 2.2.13 * (February 10th, 2009)
* Update #indexes to use unqualified table name. Fixes cases where users may decide to use table
name prefixes like 'dbo.'. [Ken Collins]
* 2.2.12 * (February 8th, 2009)
* Update table_exists? to work with qualified table names that may include an user prefix. [Ken Collins]
* 2.2.10/11 * (January 22nd, 2009)
* Add a rails-sqlserver-2000-2005-adapter.rb file so that long :lib option for config.gem is no longer needed.
* 2.2.9 * (January 22nd, 2009)
* Fixing a small bug in the deprecated DBI::Timestamp conversion so it correctly converts nanosecond whole
numbers to back to pre type cast SQL Server milliseconds, ultimately allow ruby's Time#usec which is
microseconds to be correct. [Ken Collins]
* Sometimes views are more than 4000 chars long and will return NULL for the VIEW_DEFINITION. If so, use
sp_helptext procedure as a backup method. [Ken Collins]
* 2.2.8 (January 9th, 2009)
* Update execute_procedure method a bit to remove excess code. [Ken Collins]
* 2.2.7 (January 9th, 2009)
* Created a connection#execute_procedure method that takes can take any number of ruby objects as variables
and quotes them according to the connection's rules. Also added an ActiveRecord::Base class level core
extension that hooks into this. It also checks if the connection responds to #execute_procedure and if
not returns an empty array. [Ken Collins]
* Added a #enable_default_unicode_types class attribute access to make all new added or changed string types
like :string/:text default to unicode/national data types. See the README for full details. Added a rake
task that assists setting this to true when running tests. [Ken Collins]
* 2.2.6 (January 8th, 2009)
* Introduced a bug in 2.2.5 in the #add_order! core ext for ActiveRecord. Fixed [Ken Collins]
* 2.2.5 (January 4th, 2009)
* Added a log_info_schema_queries class attribute and make all queries to INFORMATION_SCHEMA silent by
default. [Ken Collins]
* Fix millisecond support in datetime columns. ODBC::Timestamp incorrectly takes SQL Server milliseconds
and applies them as nanoseconds. We cope with this at the DBI layer by using SQLServerDBI::Type::SqlserverTimestamp
class to parse the before type cast value appropriately. Also update the adapters #quoted_date method
to work more simply by converting ruby's #usec milliseconds to SQL Server microseconds. [Ken Collins]
* Core extensions for ActiveRecord now reflect on the connection before doing SQL Server things. Now
this adapter is compatible for using with other adapters. [Ken Collins]
* 2.2.4 (December 5th, 2008)
* Fix a type left in #views_real_column_name. Also cache #view_information lookups. [Ken Collins]
* 2.2.3 (December 5th, 2008)
* Changing back to using real table name in column_definitions. Makes sure views get back only the columns
that are defined for them with correct names, etc. Now supporting views by looking for NULL default and
then if table name is a view, perform a targeted with sub select to the real table name and column name
to find true default. [Ken Collins]
* Ensure that add_limit_offset! does not alter sub queries. [Erik Bryn]
2.2.2 (December 2nd, 2008)
* Add support for view defaults by making column_definitions use real table name for schema info. [Ken Collins]
* Include version in connection method and inspection. [Ken Collins]
2.2.1 (November 25th, 2008)
* Add identity insert support for views. Cache #views so that identity #table_name_or_views_table_name
will run quickly. [Ken Collins]
* Add views support. ActiveRecord classes can use views. The connection now has a #views method and
#table_exists? will now fall back to checking views too. [Ken Collins]
2.2.0 (November 21st, 2008)
* Release for rails 2.2.2. Many many changes. [Ken Collins], [Murray Steele], [Shawn Balestracci], [Joe Rafaniello]
