MSSQL fixes and improvements

[dbsrgits/SQL-Translator.git] / Changes

# ----------------------------------------------------------
# x.xxxxx xxxx-xx-xx
# ----------------------------------------------------------

* Fixed Pg parser - caching the compiled P::RD schema is a *very*
  bad idea
* Fix MSSQL handling of ON UPDATE/DELETE RESTRICT
* Delay MSSQL FK constraint deployment until after all CREATE TABLE
  statements
* Coerce other engine's bytea/blob/clob datatypes to VarBinary

# ----------------------------------------------------------
# 0.09006 2009-06-10
# ----------------------------------------------------------
* Multiple test and dependency adhustments to make smokers happy
* Fix YAML producer wrt extra attribute
* Added support for "time(stamp) (p) with time zone" for Pg producer (mo)

# ----------------------------------------------------------
# 0.09005 2009-06-08
# ----------------------------------------------------------
* Add parser support for MySQL default values with a single quote
* Properly quote absolute table names in the MySQL producer
* Added semi-colon for (DROP|CREATE) TYPE statements in the Pg producer (wreis)
* Added CREATE VIEW subrules for mysql parser (wreis)
* ALTER TABLE/ALTER COLUMN/DROP DEFAULT support in Pg producer (mo)
* XML parser support for multi-event triggers
* SQLite producer support for multi-event triggers
* XML parser switched from XML::XPath to XML::LibXML
* Pg producer ALTER TABLE/COLUMN and DROP DEFAULT support
* MySQL producer skips length attribute for columns which do not support that
  attribute. Currently following column types are added to that list:
  date time timestamp datetime year
* Switch to Module::Install (mandates minimum perl 5.005)
* Major cleanup of GraphViz proucer
* Massive amount of fixes to SQLite/Pg/Mysql/MSSQL parsers/producers
  Fix most of the problems uncovered by the roundtrip test framework
  Some highlights:
    - Rewind exhausted globs before attempting a read
    - Do not add xml comment header if no_comments is set
    - table/field counts are held per schema object, not globally
    - no more variable table and column names in SQLite and MSSQL
    - VIEW support for Pg parser, also some cleanups
    - The way we generate Pg create view statements was not standards compliant
      (per RhodiumToad in #postgresql)
    - Disable MSSQL view/procedure production - they never worked in the first place
    - SQLite/MSSQL improvements:
      - Support parsing of all DROP clauses
      - Support parsing of field-level comments
      - When producing do not append table names to constraint/index names

# ----------------------------------------------------------
# 0.09004 2009-02-13
# ----------------------------------------------------------
* Add support for temporary tables in Pg (nachos)
* Create Trigger support for SQLite
* GraphViz producer improvements

* parsing MySQL CURRENT_TIMESTAMP as scalar ref so it can be produced without 
  quotes (jgoulah)
* Add ignore_opts parser arg (to ignore table options) in Parser::MySQL (jgoulah)
* Skip tests for buggy Spreadsheet::ParseExcel versions (rbo)
* Add support for skip tables parser arg in Parser::DBI::MySQL (jgoulah)
* Changed behaviour of ::Producer::Oracle when returning an array of statements 
  to make it compatible to DBI->do()
* Fixed a few bugs in ::Producer::Oracle
* Applied patch from jgoulah to support mysql's MERGE option
* Applied patch from rbo to add support of multiple database events on a trigger
* Applied patch from lukes to allow drop if exists in sqlite producer, with 
  version >= 3.3

  default values!
* Fixed SQLite producer to end index statements in newlines, in scalar context
* Decreed that all list context statements shall not end in ; or ;\n
* Fixed SQLite, Diff and MySQL producers to agree with Decree.

* Added support for CREATE VIEW + tests in the sqlite producer (groditi)
* Added proper argument parsing and documentation to MySQL Parser and 
  Producer (ribasushi)
* Using DROP VIEW instead of OR REPLACE clause in the Pg producer, as replace 
  only allows replacement with identical set of columns (wreis)
* Added support for DROP VIEW and fixed CREATE VIEW statement in the sqlite 
  producer (wreis)
* Removed source_db and target_db accessors from Diff (throwback to old version, 
  only output_db is used)

# 0.09001 2008-08-19
# ----------------------------------------------------------
* Added support for CREATE VIEW + tests in the mysql producer (groditi)
* Added support for SET fields in the mysql producer + test (groditi)

  of at least 4.x is supplied
* Added support for proper enums under pg (as of 8.3), with pg version check, 
  and deferrable constraints

  producer, because of a change to DBIx::Class to produce such long names in 
  some cases.

# ----------------------------------------------------------
# 0.09000 2008-02-25
# ----------------------------------------------------------

# -----------------------------------------------------------
# 0.0899_02 2008-01-29
# ----------------------------------------------------------

* Major refactoring of SQL::Translator::Diff again:
* Diff is no longer one huge monolithic function.                         
* Added more tests for diff                                               
* When producing diffs for MySQL you will (by default) get single alter 
  statements per table
* SQLite can also do remove columns (by creating a temp table as shown in 
  http://sqlite.org/faq.html#q11
* Columns can be renamed if the new schema is from a form that can have metadata
  (which is pretty much anything but an SQL file.) It does this by looking at 
  renamed_from in the $field->extra                              
* Updated Oracle and Postgres producers
* More tests!

# -----------------------------------------------------------
# 0.0899_01 2007-10-21
# ----------------------------------------------------------

* SQL::Translator::Diff now uses the ::Producer modules to create diffs
  This *will* break back-compatibility
  Use sqlt-diff-old for the previous one, and fix producers!
