L<DBIx::Custom> is the class to make easy to execute SQL.
12
This is L<DBI> wrapper class like L<DBIx::Class> or L<DBIx::Simple>.
13
You can do thing more easy than L<DBIx::Class>, more flexible
14
than L<DBIx::Simple>.

L<DBIx::Custom> is B<not< O/R mapper, O/R mapper is usefule, but
17
you must learn many things. Created SQL is sometimes inefficient,
18
and in many cases you create raw SQL because
19
O/R mapper can't make complex SQL

L<DBIx::Custom> is opposit of O/R mapper.
22
The main purpose is that we respect SQL
23
and make easy difficult works if you use only L<DBI>.
24
If you already learn SQL, it is easy to use L<DBIx::Custom>.

31
The part arround {} is tag.
32
This SQL is converted to the one which contains place holder.
33

            
34
    select * from book where title = ? and author = ?;
35

            
36
Maybe you ask me that this conversion is meaningful.
37
On the top of this, usuful features is implemented.
38
See the following descriptions.

=item 1. Specify place holder binding value as hash refernce
43

            
44
If you use L<DBI>, you must specify place holder binding value
45
as array.
46

            
47
    $sth->execute(@bind);
48

            
49
If you use L<DBIx::Custom>, you specify it as hash reference.
50
    
51
    my $param = {title => 'Perl', author => 'Ken'};
52
    $dbi->execute($sql, $param);
53

            
54
=item 2. Filtering
55

            
56
L<DBIx::Custom> provides filtering system.
57
For example, You think that about date value you want to 
58
manipulate it as date object like L<Time::Piece> in Perl,
59
and want to convert it to database DATE format.
60
and want to do reverse.
61

            
62
You can use filtering system.
63

            
64
At first, register filter.
65

            
66
    $dbi->register_filter(
67
        tp_to_date => sub {
68
            ...
69
        },
70
        date_to_tp => sub {
71
            ...
72
        }
73
    );
74

            
75
next, apply this filter to each column.
76

            
77
    $dbi->apply_filter('book',
78
        'issue_date' => {out => 'tp_to_date', in => 'date_to_tp'}
79
    );
80

            
81
C<out> is perl-to-database way. C<in> is perl-from-database way.
82

            
83
This filter is automatically enabled in many method.
84

            
85
    $dbi->insert(table => 'book', param => {issue_date => $tp});
86

            
87

            
88
=item 3. Selective search condition
89

            
90
It is difficult to create selective where clause in L<DBI>.
91
For example, If C<title> and C<author> is specified, we create 
92
the following SQL.
93

            
94
    select * from book where title = ? and author = ?;
95

            
96
If only C<title> is specified, the following one
97

            
98
    select * from book where title = ?;
99

            
100
If only C<author> is specified, the following one,
101

            
102
    select * from book where author = ?;
103

            
104
This is hard work. Generally we use modules like L<SQL::Abstract>.
105
L<DBIx::Custom> prepare the way to make it easy.
106

            
107
    # Where object
108
    my $where = $dbi->where;
109
    
110
    # Search condition
111
    $where->clause(
112
        ['and', '{= title}', {'= author'}]
113
    );
114
    
115
    # Setting to automatically select needed column
116
    $where->param({title => 'Perl'});
117

            
118
    # Embbed where clause to SQL
119
    my $sql = "select * from book $where";
120

            
121
You can create where clause which has selected search condition.
122
You can write nesting of where clause and C<or> condition
