I have just uploaded DBD::ODBC 1.47 to the CPAN. This release does contain significant changes in behaviour for unicode builds of DBD::ODBC so I hope when I warned you months ago you tested it.
Thanks to everyone on the dbi-dev list and irc that helped me work my way through the unicode issue. I'm now going to sit back and wait for the usual rush of reports from everyone who didn't test it. See below for changes since last full release. Martin 1.47 2014-02-19 Full release of the 1.46 development releases. [MISCELLANEOUS] Just some tidying up of dbdimp.c - shouldn't make a difference to anyone. Further changes to this change file to make it CPAN::Changes spec. NOTE the changes.cpanhq.com site does not yet support "unknown" for dates. 1.46_2 2013-12-17 [BUG FIXES] When built with unicode support and odbc_old_unicode is not enabled columns reported as SQL_LONGVARCHAR were not by default bound as SQL_WCHAR and hence were not returned correctly unless the bind was overridden. [MISCELLANEOUS] Added test 90_trace_flag.t 1.46_1 2013-11-16 [CHANGE IN BEHAVIOUR] As warned in release 1.45, the binding of unicode parameters to char/varchar columns has changed significantly. If you don't attempt to insert unicode into char/varchar columns or if you only inserted unicode into nchar/nvarchar columns you should see no difference. From this release, unicode data inserted into char/varchar/longvarchar columns is bound as SQL_WCHAR and not whatever the driver reports the parameter as (which is mostly SQL_CHAR). Previously if DBD::ODBC received an error or (SQL_SUCCESS_WITH_INFO) from an ODBC API call and then the driver refused to return the error state/text DBD::ODBC would issue its own error saying "Unable to fetch information about the error" and state IM008. That state was wrong and has been changed to HY000. [BUG FIXES] Some drivers cannot support catalogs and/or schema names in SQLTables. Recent changes set the schema/catalog name to the empty string (good reasons below) which causes "optional feature not implemented" from MS Access (which does not support schemas - even for a simply ping (which uses SQLTables)). Now we call SQLCATALOG_NAME and SQLSCHEMA_USAGE on connect to ascertain support which modifies SQLTables call. [MISCELLANEOUS] Added test 45_unicode_varchar.t for MS SQL Server only so far.
