108 (Mostly) object-oriented interface to database records. Records are currently
109 implemented on top of DBI. FS::Record is intended as a base class for

116 =item new [ TABLE, ] HASHREF
118 Creates a new record. It doesn't store it in the database, though. See
119 L<"insert"> for that.
121 Note that the object stores this hash reference, not a distinct copy of the
122 hash it points to. You can ask the object for a copy with the I<hash>
125 TABLE can only be omitted when a dervived class overrides the table method.

188 =item qsearch PARAMS_HASHREF | TABLE, HASHREF, SELECT, EXTRA_SQL, CACHE_OBJ, ADDL_FROM
190 Searches the database for all records matching (at least) the key/value pairs
191 in HASHREF. Returns all the records found as `FS::TABLE' objects if that
192 module is loaded (i.e. via `use FS::cust_main;'), otherwise returns FS::Record
195 The preferred usage is to pass a hash reference of named parameters:
197 my @records = qsearch( {
198 'table' => 'table_name',
199 'hashref' => { 'field' => 'value'
200 'field' => { 'op' => '<',
205 #these are optional...
207 'extra_sql' => 'AND field ',
208 #'cache_obj' => '', #optional
209 'addl_from' => 'LEFT JOIN othtable USING ( field )',
213 Much code still uses old-style positional parameters, this is also probably
214 fine in the common case where there are only two parameters:
216 my @records = qsearch( 'table', { 'field' => 'value' } );

1834 This module should probably be renamed, since much of the functionality is
1835 of general use. It is not completely unlike Adapter::DBI (see below).
1837 Exported qsearch and qsearchs should be deprecated in favor of method calls
1838 (against an FS::Record object like the old search and searchs that qsearch
1839 and qsearchs were on top of.)
1841 The whole fields / hfields mess should be removed.
1843 The various WHERE clauses should be subroutined.
1845 table string should be deprecated in favor of DBIx::DBSchema::Table.
1847 No doubt we could benefit from a Tied hash. Documenting how exists / defined
1848 true maps to the database (and WHERE clauses) would also help.
1850 The ut_ methods should ask the dbdef for a default length.
1852 ut_sqltype (like ut_varchar) should all be defined
1854 A fallback check method should be provided which uses the dbdef.
1856 The ut_money method assumes money has two decimal digits.
1858 The Pg money kludge in the new method only strips `$'.
1860 The ut_phonen method only checks US-style phone numbers.
1862 The _quote function should probably use ut_float instead of a regex.
1864 All the subroutines probably should be methods, here or elsewhere.
1866 Probably should borrow/use some dbdef methods where appropriate (like sub
1869 As of 1.14, DBI fetchall_hashref( {} ) doesn't set fetchrow_hashref NAME_lc,
1870 or allow it to be set. Working around it is ugly any way around - DBI should
1871 be fixed. (only affects RDBMS which return uppercase column names)
1873 ut_zip should take an optional country like ut_phone.
