public class S_Serialize
extends SqlExprN

TODO: Serialization expressions should not be part of the SqlExpr hierarchy! Instead, this should be a completely separate process. An expression whose purpose is to provide a means of serializing its arguments. This class is intended to be used at the end of the SQL translation process, where we no longer care about the semantics of the expression nodes; i.e. at the time where all semantic stuff has already been processed, and now we only want to generate valid SQL.
