        Performs expression rewrites which are always used unconditionally. These rewrites massage the expression tree into a standard form so that the rest of the validation logic can be simpler.

        Returns null if and only if the original expression is null.

        Parameters:
        node - expression to be rewritten
        underFrom - whether node appears directly under a FROM clause

        Allows a subclass to provide information about how to convert an UPDATE into a MERGE via self-join. If this method returns null, then no such conversion takes place. Otherwise, this method should return a suitable unique identifier expression for the given table.
        Parameters:
        table - identifier for table being updated
        alias - alias to use for qualifying columns in expression, or null for unqualified references; if this is equal to "SYS$SRC", then column references have been anonymized to "SYS$ANONx", where x is the 1-based column number.
        Returns:
        expression for unique identifier, or null to prevent conversion
