I've written a small upload utility to take a 10k+ line log file and
upload it to a database. It works fine (on the whole) except that I get
Error code: 1722
Error message: ORA-01722: invalid number
every so often. The data rows around the offending line are
01/06/05,00:43:39,0,6.67,30.3,-99.9,-99.9,-99.9,
01/06/05,00:43:49,0,6.67,30.3,-99.9,-99.9,-99.9, <- this line fails
01/06/05,00:43:59,0,6.67,30.3,-99.9,-99.9,-99.9,
(i.e. virtually identical data)
I'm using a prepared statement and my only thoughts are that there is
an issue with the driver somehow. e.g. after a certain number of
inserts or memory usage the driver fails.
Any ideas how I debug this, as inserting "broken" rows manually via
SQL*Plus succeeds every time (so it isn't the data). Anyone have
problems with the DBI functionality?
require 'dbi'
dbh = DBI.connect('DBI:Oracle:tpdev', 'username', 'password');
sth = dbh.prepare("INSERT INTO EFFLUENT_LOG (datetime, suspect, flow,
temp, ph) VALUES(to_date(?, 'DD/MM/YY HH24:MI:SS'), ?, ?, ?, ?)");
.... some loop stuff..
sth.execute((date + " " + time), val, flow.to_f, temp.to_f, ph.to_f)
... more loop stuff
Not rocket science.. but I'm confused. Is it a driver issue?
