New DBI types should use this module as a base, and override methods as needed.

Returns a Devel::Ladybug::Array of all column names in the receiving class's table.
This will be the same as the list returned by attributes(), minus any attributes which were asserted as Array or Hash and therefore live in a seperate linked table.
PRIVATE CLASS METHODS
$class->__useForeignKeys()
Returns a true value if the SQL schema should include foreign key constraints where applicable. Default is appropriate for the chosen DBI type.
$class->__datetimeColumnType();
Returns an override column type for ctime/mtime
$class->__beginTransaction();
Begins a new SQL transation.
$class->__rollbackTransaction();
Rolls back the current SQL transaction.
$class->__commitTransaction();
Commits the current SQL transaction.
$class->__beginTransactionStatement();
Returns the SQL used to begin a SQL transaction
$class->__commitTransactionStatement();
Returns the SQL used to commit a SQL transaction
$class->__rollbackTransactionStatement();
Returns the SQL used to rollback a SQL transaction
$class->__schema()
Returns the SQL used to construct the receiving class's table.
$class->__concatNameStatement()
Return the SQL used to look up name concatenated with the other attributes which it is uniquely keyed with.
$class->__statementForColumn($attr, $type, $foreign, $unique)
Returns the chunk of SQL used for this attribute in the CREATE TABLE syntax.
$class->__dropTable()
Drops the receiving class's database table.
use YourApp::Example; YourApp::Example->__dropTable();$class->__createTable()
Creates the receiving class's database table
use YourApp::Example; YourApp::Example->__createTable();Returns a string representing the name of the class's current table.
For DBs which support cross-database queries, this returns
databaseNameconcatenated withtableName(eg. "yourdb.yourclass"), otherwise this method just returns the same value astableName.$class->__selectRowStatement($id)

$class->__allIdsStatement()
Returns the SQL used to generate a list of all record ids
$class->__countStatement()
Returns the SQL used to return the number of rows in a table
$class->__doesIdExistStatement($id)
Returns the SQL used to look up the presence of an ID in the current table
$class->__doesNameExistStatement($name)
