annotate roundup/backends/rdbms_common.py @ 2098:18addf2a8596
Implemented proper datatypes in mysql and postgresql backends...
...(well, sqlite too, but that doesn't care).
Probably should use BOOLEAN instead of INTEGER for the Boolean props.
Need to fix a bizzaro MySQL error (gee, how unusual)
Need to finish MySQL migration from "version 1" database schemas.
