To build a program, you need to do
ghc --make db.hs -o db D:\Oracle\Ora92\bin\oci.dll
(put the path to your oci.dll here).
This compiles your program, and links it with oci.dll to get the Oracle externals resolved.
I've been working with Paul on his linking problems, and there's a gotcha for Oracle 10 users. Apparently the folder that contains oci.dll, typically $ORACLE_HOME/bin, can also include hsbase.dll, which has something to do with "Heterogeneous Services". Obviously (this being Windows, where filenames are not case sensitive) this clashes with GHC's HSbase.dll; hence linker errors. I'm not sure exactly what the solution should be; one obvious one is to not include "Heterogeneous Services" in your installation. I'm also not sure if this affects Oracle clients; Paul hinted that he was pointing at a server installation folder, so a standard client installation is likely to be OK.
