I caught a post on the OTN forum asking how to do this, and it happened to be something I’m working on for a new course that I’ll be teaching on data analytics. Ultimately, Microsoft Excel is the de facto tool of many accounts and financial analysts, protests notwithstanding.

This shows you how to query an Oracle 11g database from Excel 2007. Actually, it should work on any current version of the Oracle database. The key to making this work is having the Oracle 10g Client software or an Oracle 11g database on the same machine. The Oracle client software allows you to resolve an Oracle Network Alias (found in the %ORACLE_HOME%\network\admin\tnsnames.ora file).

I finally got back to synchronizing file deletion with transaction control. You’ll need some code from an earlier blog page. The reference to that page is the new page referenced below.

Probably the largest disappointment was discovering the details of global temporary tables. A commit on a DML statement against another table doesn’t trigger a DELETE event on the temporary table. This means a trigger built on a global temporary table doesn’t fire unless you delete from the temporary table. If they did, you could commit a change in one table and trigger another event through the temporary table. That would be a great feature.
