1 Revision history for SQL::Abstract
3 revision 1.79 2014-09-25
4 ----------------------------
5 - New exportable functions: is_literal_value($) and is_plain_value($)
6 - New attribute 'escape_char' allowing for proper escape of quote_chars
7 present in an identifier
8 - Deprecate { "" => \... } constructs
9 - Treat { -value => undef } as plain undef in all cases
10 - Explicitly throw on { -ident => undef }
12 revision 1.78 2014-05-28
13 ----------------------------
14 - Fix parsing of binary ops to correctly take up only a single LHS
15 element, instead of gobbling up the entire parse-to-date
16 - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
17 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind
18 - Retire script/format-sql - the utility needs more work to be truly
21 revision 1.77 2014-01-17
22 ----------------------------
23 - Reintroduce { -not => undef } column operator (regression from 1.75)
25 revision 1.75 2013-12-27
26 ----------------------------
27 - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
28 on undef-containing lists fed to -in and -not_in. An exception will
29 be raised for a while before properly fixing this, to avoid quiet
30 but subtle changes to query results in production
31 - Deprecate and warn when supplying an empty arrayref to like/not_like
32 operators (likely to be removed before 2.0)
34 - Warn when using an inequality operator with a multi-value array to
35 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
36 this behavior due to backwards comp concerns)
37 - Fix false negative comparison of ORDER BY <function> ASC
38 - More improvements of incorrect parsing (placeholder at end of list
40 - Fix typos in POD and comments (RT#87776)
41 - Augment -not_bool example with nesting (RT#89601)
43 revision 1.74 2013-06-04
44 ----------------------------
45 - Fix insufficient parenthesis unroll during operator comparison
46 - 'ORDER BY foo' and 'ORDER BY foo ASC' are now considered equal
47 by default (with a switch to reenable old behavior when necessary)
48 - Change parser to not eagerly slurp RHS expressions it doesn't recognize
50 revision 1.73 2012-07-10
51 ----------------------------
52 - Fix parsing of ORDER BY foo + ?
53 - Stop filling in placeholders in `format-sql` since it does not support
54 passing values for them anyway
55 - Fix parsing of NOT EXISTS

235 Version 1.50 was a major internal refactoring of SQL::Abstract.
236 Great care has been taken to preserve the published behavior
237 documented in previous versions in the 1.* family; however,
238 some features that were previously undocumented, or behaved.
239 differently from the documentation, had to be changed in order
240 to clarify the semantics. Hence, client code that was relying
241 on some dark areas of SQL::Abstract v1.* might behave differently
244 ----------------------------

269 - fixed semantics of _bindtype on array args
270 - dropped the _anoncopy of the %where tree. No longer necessary.
271 - dropped the _modlogic function
