NAME

DBIx::Sunny - Simple DBI wrapper

SYNOPSIS

use DBIx::Sunny;

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

# or 

use DBI;

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

DESCRIPTION

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.

FEATURES

Set AutoInactiveDestroy to true.

DBIx::Sunny sets AutoInactiveDestroy as true.

[SQLite/MySQL] Auto encode/decode utf-8

DBIx::Sunny sets sqlite_unicode and mysql_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)

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/

$dbh->query(
    'INSERT INTO bin_table (bin_col) VALUES (?)',
    sql_type(\"\xDE\xAD\xBE\xEF", SQL_BINARY)),
);

ADDITIONAL METHODS

$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 => {} }, ..)

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

Shortcut for prepare, execute.
