1 Revision history for SQL::Abstract
3 - New exportable functions: is_literal_value($) and is_plain_value($)
4 - New attribute 'escape_char' allowing for proper escape of quote_chars
5 present in an identifier
6 - Treat { -value => undef } as plain undef in all cases
7 - Explicitly throw on { -ident => undef }
9 revision 1.78 2014-05-28
10 ----------------------------
11 - Fix parsing of binary ops to correctly take up only a single LHS
12 element, instead of gobbling up the entire parse-to-date
13 - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
14 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind
15 - Retire script/format-sql - the utility needs more work to be truly
18 revision 1.77 2014-01-17
19 ----------------------------
20 - Reintroduce { -not => undef } column operator (regression from 1.75)
22 revision 1.75 2013-12-27
23 ----------------------------
24 - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
25 on undef-containing lists fed to -in and -not_in. An exception will
26 be raised for a while before properly fixing this, to avoid quiet
27 but subtle changes to query results in production
28 - Deprecate and warn when supplying an empty arrayref to like/not_like
29 operators (likely to be removed before 2.0)
31 - Warn when using an inequality operator with a multi-value array to
32 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
33 this behavior due to backwards comp concerns)
34 - Fix false negative comparison of ORDER BY <function> ASC
35 - More improvements of incorrect parsing (placeholder at end of list
37 - Fix typos in POD and comments (RT#87776)
38 - Augment -not_bool example with nesting (RT#89601)

47 revision 1.73 2012-07-10

87 - Color and indent pagination keywords
88 - Fix a silly bug which broke placeholder fill-in in DBIC
89 - Installs format-sql to format SQL passed in over STDIN
90 - Switch the tokenizer to precompiled regexes (massive speedup)

92 - Fix extended argument parsing by IN/BETWEEN
93 - Add proper handling of lists (foo,bar,?)
94 - Better handling of generic -function's during AST construction
95 - Special handle IS NOT? NULL

232 Version 1.50 was a major internal refactoring of SQL::Abstract.
233 Great care has been taken to preserve the published behavior
234 documented in previous versions in the 1.* family; however,
235 some features that were previously undocumented, or behaved.
236 differently from the documentation, had to be changed in order
237 to clarify the semantics. Hence, client code that was relying
238 on some dark areas of SQL::Abstract v1.* might behave differently
241 ----------------------------
