Does python-sql address back end specific issues?

It will not work if there is a '?' in the query that is not a keyword.
For me, the best way will be implement such things in python-sql.

I made some test and I think the issue is about the CAST affinity of SQLite.
As we store NUMERIC as blob in SQLite to prevent precision lost, I think SQLite
make the comparison between NUMERIC and NONE.
So if we cast both side of the expression, it works:


A quick test show that it also work on PostgreSQL.

The problem occurs on size comparison like < <= => > when a string is cast to
This kind of cast is used for example for the property field, where
all data is stored as string and cast to the proper type for comparison.
