1 Revision history for SQL::Abstract
3 - Fix erroneous behavior of is_literal_value($) wrt { -ident => ... }
5 revision 1.79 2014-09-25
6 ----------------------------
7 - New exportable functions: is_literal_value($) and is_plain_value($)
8 - New attribute 'escape_char' allowing for proper escape of quote_chars
9 present in an identifier

12 - Explicitly throw on { -ident => undef }
14 revision 1.78 2014-05-28
15 ----------------------------
16 - Fix parsing of binary ops to correctly take up only a single LHS
17 element, instead of gobbling up the entire parse-to-date
18 - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
19 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind

24 ----------------------------
25 - Reintroduce { -not => undef } column operator (regression from 1.75)
27 revision 1.75 2013-12-27
28 ----------------------------
29 - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
30 on undef-containing lists fed to -in and -not_in. An exception will
31 be raised for a while before properly fixing this, to avoid quiet
32 but subtle changes to query results in production
33 - Deprecate and warn when supplying an empty arrayref to like/not_like
34 operators (likely to be removed before 2.0)
36 - Warn when using an inequality operator with a multi-value array to
37 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
38 this behavior due to backwards comp concerns)
39 - Fix false negative comparison of ORDER BY <function> ASC
40 - More improvements of incorrect parsing (placeholder at end of list
42 - Fix typos in POD and comments (RT#87776)
43 - Augment -not_bool example with nesting (RT#89601)

46 ----------------------------
47 - Fix insufficient parenthesis unroll during operator comparison
48 - 'ORDER BY foo' and 'ORDER BY foo ASC' are now considered equal
49 by default (with a switch to reenable old behavior when necessary)
50 - Change parser to not eagerly slurp RHS expressions it doesn't recognize
52 revision 1.73 2012-07-10
53 ----------------------------

237 Version 1.50 was a major internal refactoring of SQL::Abstract.
238 Great care has been taken to preserve the published behavior
239 documented in previous versions in the 1.* family; however,
240 some features that were previously undocumented, or behaved.
241 differently from the documentation, had to be changed in order
242 to clarify the semantics. Hence, client code that was relying
243 on some dark areas of SQL::Abstract v1.* might behave differently
246 ----------------------------
