I want to choose an embedded scripting language that i will use on C++. It should connect a database such as Oracle. My host application is a server application. That will pass raw data to script. The script will parse and do some specific logics. Also updates database. Then script will returns raw data as result.
Can you help me to choose it?
Thanx
TCL would be another option for an easy to embed scripting language. 
personally I'd go with the scripting language you and/or whoever will be using the scripting language is most familiar with already, especially if end users will be able to run custom scripts, you will need to know what, if any, languages they are familiar with in their business domain e.g. CAD/CAM people may know TCL, gaming people may know Lua etc.
