Module SQLToken

This module defines the Token needed to scan an embedded SQL Statement. In Addition it defines a ToString-method for all token. The supported datatypes, functions, operator etc. are based on the CDBI-Interface.

Summary of exported operations:

tokentoString :: Token -> String  Deterministic
