Changes for version 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.

Changes for version 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

Changes for version 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.
