This takes a table name and optional hashref L<WHERE clause|/WHERE CLAUSES>.
It returns an SQL DELETE statement and list of bind values.
-=head2 where(\%where, \@order)
+=head2 where(\%where, $order)
This is used to generate just the WHERE clause. For example,
if you have an arbitrary data structure and know what the
historical reasons. So be careful : the two examples below would
seem algebraically equivalent, but they are not
- {col => [-and => {-like => 'foo%'}, {-like => '%bar'}]}
+ { col => [ -and =>
+ { -like => 'foo%' },
+ { -like => '%bar' },
+ ] }
# yields : WHERE ( ( col LIKE ? AND col LIKE ? ) )
- [-and => {col => {-like => 'foo%'}, {col => {-like => '%bar'}}]]
+ [ -and =>
+ { col => { -like => 'foo%' } },
+ { col => { -like => '%bar' } },
+ ]
# yields : WHERE ( ( col LIKE ? OR col LIKE ? ) )
@bind = ('10');
Note that you must pass the bind values in the same format as they are returned
-by L<where|/where(\%where, \@order)>. This means that if you set L</bindtype>
+by L<where|/where(\%where, $order)>. This means that if you set L</bindtype>
to C<columns>, you must provide the bind values in the
C<< [ column_meta => value ] >> format, where C<column_meta> is an opaque
scalar value; most commonly the column name, but you can use any scalar value
