1094 =item fields [ TABLE ]
1096 This can be used as both a subroutine and a method call. It returns a list
1097 of the columns in this record's table, or an explicitly specified table.
1098 (See L<DBIx::DBSchema::Table>).

1126 Load a database definition (see L<DBIx::DBSchema>), optionally from a

1147 Returns the current database definition. See L<DBIx::DBSchema>.
1151 sub dbdef { $dbdef; }
1153 =item _quote VALUE, TABLE, COLUMN
1155 This is an internal function used to construct SQL statements. It returns
1156 VALUE DBI-quoted (see L<DBI/"quote">) unless VALUE is a number and the column
1157 type (see L<DBIx::DBSchema::Column>) does not end in `char' or `binary'.
1162 my($value,$table,$field)=@_;
1164 if ( $value =~ /^\d+(\.\d+)?$/ &&
1165 # ! ( datatype($table,$field) =~ /^char/ )
1166 ! $dbdef->table($table)->column($field)->type =~ /(char|binary|text)$/i
1170 $dbh->quote($value);
1176 This is depriciated. Don't use it.
1178 It returns a hash-type list with the fields of this record's table set true.
1183 carp "warning: hfields is depriciated";
1186 foreach (fields($table)) {
1195 "$_: ". $self->getfield($_). "|"
1196 } (fields($self->table)) );

1203 # #use Carp qw(cluck);
1204 # #cluck "DESTROYING $self";
1205 # warn "DESTROYING $self";
1209 # return ! eval { join('',@_), kill 0; 1; };
1216 This module should probably be renamed, since much of the functionality is
1217 of general use. It is not completely unlike Adapter::DBI (see below).
1219 Exported qsearch and qsearchs should be depriciated in favor of method calls
1220 (against an FS::Record object like the old search and searchs that qsearch
1221 and qsearchs were on top of.)
1223 The whole fields / hfields mess should be removed.
1225 The various WHERE clauses should be subroutined.
1227 table string should be depriciated in favor of DBIx::DBSchema::Table.
1229 No doubt we could benefit from a Tied hash. Documenting how exists / defined
1230 true maps to the database (and WHERE clauses) would also help.
1232 The ut_ methods should ask the dbdef for a default length.
1234 ut_sqltype (like ut_varchar) should all be defined
1236 A fallback check method should be provided which uses the dbdef.
1238 The ut_money method assumes money has two decimal digits.
1240 The Pg money kludge in the new method only strips `$'.
1242 The ut_phonen method only checks US-style phone numbers.
1244 The _quote function should probably use ut_float instead of a regex.
1246 All the subroutines probably should be methods, here or elsewhere.
1248 Probably should borrow/use some dbdef methods where appropriate (like sub
1251 As of 1.14, DBI fetchall_hashref( {} ) doesn't set fetchrow_hashref NAME_lc,
1252 or allow it to be set. Working around it is ugly any way around - DBI should
1253 be fixed. (only affects RDBMS which return uppercase column names)
1255 ut_zip should take an optional country like ut_phone.
