You can also work around this limitation with the following:

   -- for example, with MyVarCharField VARCHAR(1000)
   SELECT CAST(MyVarCharField AS TEXT) FROM MyTable

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;
