rspec/rules/S4078/tsql/rule.adoc

String data types (``++char++``, ``++varchar++``, ``++nchar++``, ``++nvarchar++``) default to a size of 1 if no size is specified in the declaration. For ``++char++`` and ``++nchar++`` this is confusing at best, but it is most probably a mistake for ``++varchar++`` and ``++nvarchar++``.


This rule raises an issue when no size is specified for ``++varchar++`` or ``++nvarchar++``.
