Module pydo.dbtypes
The dbtypes module contains generic type wrapper classes for values
passed into PyDO, to provide type information useful into marshalling the
data into SQL according to the intended datatype. Some mapping of
datatype can be done solely on the basis of Python type, but at times it
may be necessary to be more specific.
DBAPI-compliant drivers use wrapper classes for this purpose, but they
are specific to the underlying driver; these wrappers can be used with
all drivers.
If you insert or update a wrapped value into a PyDO instance, the
value of the corresponding column in that instance will be the unwrapped
value, not the wrapper itself.
