Hi, Peter I did and uploaded some examples regarding Oracle and Takusen and the intended approach you would employ. Example 01: Create table and some tuples. http://hpaste.org/fastcgi/hpaste.fcgi/view?id=29883#a29883 Example 02: Create a package with procedures to mantain the table. http://hpaste.org/fastcgi/hpaste.fcgi/view?id=29884#a29884 Example 03: Optional. See how it works in Oracle sqlplus. http://hpaste.org/fastcgi/hpaste.fcgi/view?id=29885#a29885 Example 04: The Takusen-Haskell program. It follows the scheme of example #03. http://hpaste.org/fastcgi/hpaste.fcgi/view?id=29894#a29894 Some comments on the topic: This approach has limitations. Takusen (if not use in conjunction with Template Haskell) will be bound up to iteratees of eight values. I (and I'm pretty sure some other people) have successfully used Template Haskell to overcome this limitation. (I've been working in removing some boilerplate). The all stored procedure approach is not a limitation as you can see from example #04, unless these procedures return values these types: Record Of <something>, complex objects (PL/SQL tables, objects, etc), Boolean. Oracle has several programatic interfaces, some that I remember: JDBC, ODBC, OCI, OCCI and those for Windows .NET. Takusen is a wrapper for OCI (Oracle Call Interface) which seems to me pretty low level. Yet, I don't know if you can specify just the name of the procedure. Please note that if there is a procedure named close_accounts, by writing "begin close_accounts; end;" you are not wrapping it in a SQL statement. It actually is an anonymous PL/SQL block and it is needed in that form to be processed by the server. Oracle offers for Windows .NET: ODT (Oracle Developer Tools for Visual Studio), ODP (Oracle Data Provider) and ODE (Oracle Database Extensions). I did test (and taste) a bit of .NET tools with F#. It was nice. Maybe you wish to try hs-dotnet with these. A final remark, I have used Takusen both on Windows and Linux. The given example was developed and tested actually on Windows.
