• Rerelease last version to not include .svn files and grab MANIFEST.SKIP from DBIx::Class so it won't happen again

• Fix multiple generic op handling regressions by reverting the auto-equality assumption (turned out to be a very very bad idea)

revision 1.63 2010-03-24 09:56 (UTC)

• Add ILIKE to the core list of comparision ops

revision 1.62 2010-03-15 11:06 (UTC)

• unroll multiple parenthesis around IN arguments to accomodate crappy databases

revision 1.58 2009-09-04 15:20 (UTC)

• expanded the scope of -bool and -not_bool operators
• added proper testing support

revision 1.57 2009-09-03 20:18 (UTC)

• make sure that sql generation does not mutate the supplied where condition structure

revision 1.54 2009-05-07 17:23 (UTC)

• allow special_operators to take both code refs and method names (makes it possible to properly subclass the builtin ones)

• more tests and clearing up of some corner cases
• t/10test.t does not run by default (developer only, too cpu intensive)

• fixed behavior of [-and => ... ] depending on the current condition scope. This introduces backwards comp with 1.24

• fixed interjecting arrayrefref into a where clause
• added value-only insert test with a literal SQL snippet
• cleanup and enhancement of t/03values.t

• fixed test subs (is_same_*) in SQL::Abstract::Test to return the correct test value
• do not version MANIFEST

Version 1.50 was a major internal refactoring of SQL::Abstract. Great care has been taken to preserve the published behavior documented in previous versions in the 1. family; however, some features that were previously undocumented, or behaved. differently from the documentation, had to be changed in order to clarify the semantics. Hence, client code that was relying on some dark areas of SQL::Abstract v1. might behave differently in v1.50.

• add support for a [\%column_meta => value] bind value format

• clarify syntax of \['...', @bind] when used with a bindtype of 'columns'

• added an AST-aware SQL::Abstract::Test library for sql syntax tests
• vastly expanded test coverage
• support for the { operator => \'...'|\['...', @bind] } syntax allowing to embed arbitrary operators on the LHS
• fixed multiple regressions wrt DBIx::Class

• support for literal SQL through the [$sql, bind] syntax.
• added -nest1, -nest2 or -nest_1, -nest_2, ...
• optional support for array datatypes
• defensive programming : check arguments to functions/methods
• fixed bug with global logic of -and/-or (no side-effects any more)
• changed logic for distributing an op over arrayrefs
• fixed semantics of _bindtype on array args
• dropped the _anoncopy of the %where tree. No longer necessary.
• dropped the _modlogic function
• Make col => [] and col => {$op => [] } DTRT or die instead of generating broken SQL. Added tests for this.
• Added { -desc => 'column' } order by support
• Tiny "$_"-related fix for { -desc => 'columns'} order by support tests + docs
