Sorry, my mistake, it's only throwing an EAccessViolation because I'm
trying to use a column that is not found, i.e.

pCur->ParamByName("USER_NAME")->AsString = blah;

ParamByName is returning NULL. I cannot understand why ParamByName is
not returning a column for "USER_NAME" when "USER_NAME" is displayed
as a column if I step through the Params, which list "USER_NAME" and "PW"
