Heya Paul, I'm coming up with a problem that I can't seem to figure out - was wondering if you or one of the other Zope-types out there could shed some light... I've got a table that includes this field: TIMESTAMP NOT NULL NUMBER(38) I'm trying to write a method to talk to it, as so: select * from unresolved_flows where timestamp > '<!--#sqlvar start_time type=float-->' and timestamp < '<!--#sqlvar end_time type=float-->' (This is simply the latest try - I've tried #var end_time fmt=sql-quote, and that doesn't seem to be any different). The error I'm getting back from ZOracleDA (well, from DCOracle, to be precise, through your ZOracleDA) is: Error, oci.error: (1455, 'ORA-01455: converting column overflows integer datatype\012') SQL used: select * from unresolved_flows where timestamp > '916324638' and timestamp < '916411017' I get the same thing, incidentally, when I import DCOracle, and run the query direct. I don't get the same thing if I import oracledb (Anthony Baxter's oracle module) and run that query. I'm baffled. Anyone spot an easy fix for this? KevinL
