[DB-SIG] None and BOOLEAN columns

[Dittmar, Daniel]

What is the expected behaviour with regard to NULL, TRUE, FALSE and BOOLEAN
columns?

In the SAP DB driver, I translate None (or any other value interpreted as
false) to a SQL False value, so there is currently no possibility to insert
a real NULL value.

On SELECT, I translate both NULL and FALSE to None.

Admittedly, this comes from my own Python + SQL style, where I use None as
false on the Python side and try to stay away from three valued logic on the
SQL side.

What do other drivers do?
