there are same problem with VARBINARY, if you are forced to use existing database with such fields you can do it like this:



SELECT CAST(master.dbo.fn_varbintohexstr(VARBINARYFIELD) AS TEXT) FROM table;

You can also work around this limitation with the following:



   -- for example, with MyVarCharField VARCHAR(1000)

   SELECT CAST(MyVarCharField AS TEXT) FROM MyTable
