1 Revision history for SQL::Abstract
3 - New exportable functions: is_literal_value($) and is_plain_value($)

5 present in an identifier

7 - Treat { -value => undef } as plain undef in all cases

10 revision 1.78 2014-05-28
11 ----------------------------
12 - Fix parsing of binary ops to correctly take up only a single LHS
13 element, instead of gobbling up the entire parse-to-date
14 - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
15 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind
16 - Retire script/format-sql - the utility needs more work to be truly
19 revision 1.77 2014-01-17
20 ----------------------------
21 - Reintroduce { -not => undef } column operator (regression from 1.75)

24 ----------------------------
25 - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
26 on undef-containing lists fed to -in and -not_in. An exception will
27 be raised for a while before properly fixing this, to avoid quiet
28 but subtle changes to query results in production
29 - Deprecate and warn when supplying an empty arrayref to like/not_like
30 operators (likely to be removed before 2.0)
32 - Warn when using an inequality operator with a multi-value array to
33 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
34 this behavior due to backwards comp concerns)
35 - Fix false negative comparison of ORDER BY <function> ASC
36 - More improvements of incorrect parsing (placeholder at end of list
38 - Fix typos in POD and comments (RT#87776)
39 - Augment -not_bool example with nesting (RT#89601)

48 revision 1.73 2012-07-10

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