1 Revision history for SQL::Abstract
3 - New attribute 'escape_char' allowing for proper escape of quote_chars
4 present in an identifier
6 revision 1.78 2014-05-28
7 ----------------------------
8 - Fix parsing of binary ops to correctly take up only a single LHS
9 element, instead of gobbling up the entire parse-to-date
10 - Explicitly handle ROW_NUMBER() OVER as the snowflake-operator it is
11 - Improve signatures/documentation of is_same_sql_bind / eq_sql_bind
12 - Retire script/format-sql - the utility needs more work to be truly
15 revision 1.77 2014-01-17
16 ----------------------------
17 - Reintroduce { -not => undef } column operator (regression from 1.75)
19 revision 1.75 2013-12-27
20 ----------------------------
21 - *UPCOMING INCOMPATIBLE BUGFIX*: SQLA used to generate incorrect SQL
22 on undef-containing lists fed to -in and -not_in. An exception will
23 be raised for a while before properly fixing this, to avoid quiet
24 but subtle changes to query results in production
25 - Deprecate and warn when supplying an empty arrayref to like/not_like
26 operators (likely to be removed before 2.0)
28 - Warn when using an inequality operator with a multi-value array to
29 arrive at what amounts to a 1=1 condition (no pre-2.0 plans to fix
30 this behavior due to backwards comp concerns)
31 - Fix false negative comparison of ORDER BY <function> ASC
32 - More improvements of incorrect parsing (placeholder at end of list
34 - Fix typos in POD and comments (RT#87776)
35 - Augment -not_bool example with nesting (RT#89601)
37 revision 1.74 2013-06-04
38 ----------------------------
39 - Fix insufficient parenthesis unroll during operator comparison
40 - 'ORDER BY foo' and 'ORDER BY foo ASC' are now considered equal
41 by default (with a switch to reenable old behavior when necessary)
42 - Change parser to not eagerly slurp RHS expressions it doesn't recognize
44 revision 1.73 2012-07-10
45 ----------------------------
46 - Fix parsing of ORDER BY foo + ?
47 - Stop filling in placeholders in `format-sql` since it does not support

61 - Fix parsing of foo.* in SQLA::Tree
62 - Fix bindtype fail when using -between with arrayrefref literals
63 - Add handling for NULL for -in
64 - The -nest operator has entered semi-deprecated status and has been
65 undocumented. Please do not use it in new code

83 magenta instead of cyan
84 - Color and indent pagination keywords
85 - Fix a silly bug which broke placeholder fill-in in DBIC
86 - Installs format-sql to format SQL passed in over STDIN
87 - Switch the tokenizer to precompiled regexes (massive speedup)
88 - Rudimentary handling of quotes ( 'WHERE' vs WHERE )
89 - Fix extended argument parsing by IN/BETWEEN
90 - Add proper handling of lists (foo,bar,?)
91 - Better handling of generic -function's during AST construction
92 - Special handle IS NOT? NULL
93 - Make sure unparse() does not destroy a passed in \@bindargs

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

263 - fixed semantics of _bindtype on array args
264 - dropped the _anoncopy of the %where tree. No longer necessary.
265 - dropped the _modlogic function
