DBIx::Sunny - Simple DBI wrapper


    use DBIx::Sunny;

    my $dbh = DBIx::Sunny->connect(...);

    # or

    use DBI;

    my $dbh = DBI->connect(.., {
        RootClass => 'DBIx::Sunny',
        PrintError => 0,
        RaiseError => 1,


DBIx::Sunny is a simple DBI wrapper. It provides better usability for you. This module based on Amon2::DBI. DBIx::Sunny supports only SQLite and MySQL.


Set AutoInactiveDestroy to true.

DBIx::Sunny sets AutoInactiveDestroy as true.

[SQLite/MySQL/Pg] Auto encode/decode UTF-8

DBIx::Sunny sets sqlite_unicode, mysql_enable_utf8 and pg_enable_utf8 automatically.

[SQLite] Performance tuning

DBIx::Sunny sets sqlite_use_immediate_transaction to true, and executes these PRAGMA statements

  PRAGMA journal_mode = WAL
  PRAGMA synchronous = NORMAL
Nested transaction management.

DBIx::Sunny supports nested transaction management based on RAII like DBIx::Class or DBIx::Skinny. It uses DBIx::TransactionManager internally.

Error Handling

DBIx::Sunny sets RaiseError and ShowErrorStatement as true. DBIx::Sunny raises exception and shows current statement if your $dbh occurred exception.

SQL comment

DBIx::Sunny adds file name and line number as SQL comment that invokes SQL statement.

Easy access to last_insert_id

DBIx::Sunny's last_insert_id needs no arguments. It's shortcut for mysql_insertid or last_insert_rowid.

Auto expanding arrayref bind parameters

select_(one|row|all) and query methods support auto-expanding arrayref bind parameters.

  $dbh->select_all('SELECT * FROM id IN (?)', [1 2 3])
  #SQL: 'SELECT * FROM id IN (?,?,?)'
  #@BIND: (1, 2, 3)
Named placeholder

select_(one|row|all) and query methods support named placeholder.

  $dbh->select_all('SELECT * FROM users WHERE id IN (:ids) AND status = :status', {
      ids    => [1,2,3],
      status => 'active',
  #SQL: 'SELECT * FROM users WHERE id IN (?,?,?) AND status = ?'
  #@BIND: (1, 2, 3, 'active')
Typed bind parameters

DBIx::Sunny allows you to specify data types of bind parameters. If a bind parameter is SQL::Maker::SQLType object, its value is passed as its type, otherwise it is passed as default type (VARCHAR).

  use SQL::Maker::SQLType qw/sql_type/;
  use DBI qw/:sql_types/

      'INSERT INTO bin_table (bin_col) VALUES (?)',
      sql_type(\"\xDE\xAD\xBE\xEF", SQL_BINARY)),


$col = $dbh->select_one($query, @bind);

Shortcut for prepare, execute and fetchrow_arrayref->[0]

$row = $dbh->select_row($query, @bind);

Shortcut for prepare, execute and fetchrow_hashref

$rows = $dbh->select_all($query, @bind);

Shortcut for prepare, execute and selectall_arrayref(.., { Slice => {} }, ..)

$model = $dbh->select_row_as($model_class, $query, @bind);

Shortcut for $model_class->new(%{ $dbh->select_row($query, @bind) });

$models = $dbh->select_all_as($model_class, $query, @bind);

Shortcut for [ map { $model_class->new(%$_) } @{ $dbh->select_all($query, @bind) } ];

$dbh->query($query, @bind);

Shortcut for prepare, execute.
