SQL-92 defines a "row value constructor" expression like "(1,2,3)" which looks and behaves exactly like a Python tuple, as far as I can tell. These are implemented correctly in mysql at least, and I believe PostgreSQL and Oracle as well, although I don't have access to those systems.
What would be the best way to deal with this type of value in SQLAlchemy? Should I create a RowValue class which can be visited by the various dialects? If I wanted to provide emulation for dialects which don't directly support this standard, what would be the way to go? For example, I'd like to be able to expand "RowValue((1,2)) >= RowValue(colA, colB)" to "1 > colA or (1=colA and 2 >= ColB)" under sqlite. --Buck -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
