v0.3.1

• "CheckExistenceBy" in the Insert data builder what adds WHERE EXISTS(...) to a Insert source to avoid duplicates inserting;
• ExistsIn<TTable>(..predicate..) ... - Helper that returns boolean expression EXISTS(SELECT 1 FROM TTable WHERE ..Predicate..)

Bugfix

• When some column(s) in values constructor contains only nulls, sqexpress now adds an explicit type cast for the first cell e.g. CAST(NULL as int)
• MergeDataInto now allows only keys mapping unless WhenMatchThenUpdate is defined (without additional updates)
• Derived tables now can have 0 declared columns
