Database.HsSqlPpp.Ast
Description
This module contains the ast node data types. They are very permissive, in that they allow a lot of invalid SQL to be represented. The type checking process should catch all invalid trees, but doesn't quite manage at the moment. Sorry about all the seemingly pointless type synonyms below, they are an artefact of using UUAGC. You can see labels for the fields by looking at the ag source here: http://jakewheat.github.com/hssqlppp/source/src/Database/HsSqlPpp/AstInternals/AstInternal.ag.html
