1566 This module should probably be renamed, since much of the functionality is
1567 of general use. It is not completely unlike Adapter::DBI (see below).
1569 Exported qsearch and qsearchs should be deprecated in favor of method calls
1570 (against an FS::Record object like the old search and searchs that qsearch
1571 and qsearchs were on top of.)
1573 The whole fields / hfields mess should be removed.
1575 The various WHERE clauses should be subroutined.
1577 table string should be deprecated in favor of DBIx::DBSchema::Table.
1579 No doubt we could benefit from a Tied hash. Documenting how exists / defined
1580 true maps to the database (and WHERE clauses) would also help.
1582 The ut_ methods should ask the dbdef for a default length.
1584 ut_sqltype (like ut_varchar) should all be defined
1586 A fallback check method should be provided which uses the dbdef.
1588 The ut_money method assumes money has two decimal digits.
1590 The Pg money kludge in the new method only strips `$'.
1592 The ut_phonen method only checks US-style phone numbers.
1594 The _quote function should probably use ut_float instead of a regex.
1596 All the subroutines probably should be methods, here or elsewhere.
1598 Probably should borrow/use some dbdef methods where appropriate (like sub
1601 As of 1.14, DBI fetchall_hashref( {} ) doesn't set fetchrow_hashref NAME_lc,
1602 or allow it to be set. Working around it is ugly any way around - DBI should
1603 be fixed. (only affects RDBMS which return uppercase column names)
1605 ut_zip should take an optional country like ut_phone.
