848 This module should probably be renamed, since much of the functionality is
849 of general use. It is not completely unlike Adapter::DBI (see below).
851 Exported qsearch and qsearchs should be depriciated in favor of method calls
852 (against an FS::Record object like the old search and searchs that qsearch
853 and qsearchs were on top of.)
855 The whole fields / hfields mess should be removed.
857 The various WHERE clauses should be subroutined.
859 table string should be depriciated in favor of FS::dbdef_table.
861 No doubt we could benefit from a Tied hash. Documenting how exists / defined
862 true maps to the database (and WHERE clauses) would also help.
864 The ut_ methods should ask the dbdef for a default length.
866 ut_sqltype (like ut_varchar) should all be defined
868 A fallback check method should be provided which uses the dbdef.
870 The ut_money method assumes money has two decimal digits.
872 The Pg money kludge in the new method only strips `$'.
874 The ut_phonen method assumes US-style phone numbers.
876 The _quote function should probably use ut_float instead of a regex.
878 All the subroutines probably should be methods, here or elsewhere.
880 Probably should borrow/use some dbdef methods where appropriate (like sub
883 As of 1.14, DBI fetchall_hashref( {} ) doesn't set fetchrow_hashref NAME_lc,
884 or allow it to be set. Working around it is ugly any way around - DBI should
885 be fixed. (only affects RDBMS which return uppercase column names)
