It is not completely unlike Adapter::DBI (see below). - -Exported qsearch and qsearchs should be deprecated in favor of method calls -(against an FS::Record object like the old search and searchs that qsearch -and qsearchs were on top of.) - -The whole fields / hfields mess should be removed. - -The various WHERE clauses should be subroutined. - -table string should be deprecated in favor of DBIx::DBSchema::Table. - -No doubt we could benefit from a Tied hash. Documenting how exists / defined -true maps to the database (and WHERE clauses) would also help. - -The ut_ methods should ask the dbdef for a default length. - -ut_sqltype (like ut_varchar) should all be defined - -A fallback check method should be provided which uses the dbdef. - -The ut_money method assumes money has two decimal digits. - -The Pg money kludge in the new method only strips `$'. - -The ut_phonen method only checks US-style phone numbers. - -The _quote function should probably use ut_float instead of a regex. - -All the subroutines probably should be methods, here or elsewhere. - -Probably should borrow/use some dbdef methods where appropriate (like sub -fields) - -As of 1.14, DBI fetchall_hashref( {} ) doesn't set fetchrow_hashref NAME_lc, -or allow it to be set. Working around it is ugly any way around - DBI should -be fixed. (only affects RDBMS which return uppercase column names) - -ut_zip should take an optional country like ut_phone. - -=head1 SEE ALSO - -L<DBIx::DBSchema>, L<FS::UID>, L<DBI> - -Adapter::DBI from Ch. 11 of Advanced Perl Programming by Sriram Srinivasan. - -http://poop.sf.net/ - -=cut - -1; - |
