I recently did the same thing, I left DELIMITER alone since \t is the
default, but I did have to do "WITH NULL as ''" since some of the
datetimes in MSSQL were empty.

By default the copy will bomb out on NULL fields even if you don't
have a NOT NULL constraint on the column, for one reason or another.

I suppose "WITH NULL as NULL" would've worked just as well, in hindsight.
