Hmm...  My debug code tries to convert the reported type of the column
back into a text string and comes up with CS_FORCE_CLOSE!?!

The debug code groups binary values into categories.  When doing a
lookup, it tries to resolve the value in the VAL_TYPE category and
fails.  It then just returns anything which matches the value.

Looking at the FreeTDS header, this value corresponds to the type
CS_UNIQUE_TYPE (which I don't have in my module).  Maybe I should
download the latest Sybase packages.

Try building statements which select one column at a time to see which
column types are causing the module to trip up.
