Fastest way to load data From MS Access to Oracle DB

Question

Hi All,
We get an Access DB every week which we need to load to an Oracle DB, currently we have been using SQL loader but the process is slightly painful and horribly boring, so m trying to do some automation kind of stuff. I was thinking of doing the whole thing using a java application and then schedule it to run it at some pre-decided time. The approach I took was to read the access file and then load it using PreparedStatements to the oracle DB. But going through various threads in the forum, i found that its going to b a bit too slow (and the record count in my tables is around 600,000). Can there be a better way to do this? anyone done something similar b4.

Answer 1

Well the only reason I want to use Java (i may go for C#) is that i dont want to spend time manually creating those CSV files from Access. Can that be done using something else?So use java to create the CSV files.
And have you actually tried going straight to Oracle? What exactly is your time constraint?
And another issue is that I sometimes have to make some adjustments (rounding off) to the data which is usually through query, but that is usually done after the data has been loaded in the DB.Which would make it irrelevant to actually moving the data then. If you are cleaning the data with SQL already then it is simple to wrap that in a proc and do it that way. Presumably you are loading to temp (non-production in-lined) tables first, then cleaning and moving.
