Hmm, this works on my end.  I tested on OS X.4 running MySQL 4.1.   
Not sure why you are losing all of your data.  This seems really odd.

revDataFromQuery should work correctly in this context since it will  
return the text of the result of the query which should be the number  
of records in the table.  revExecuteSQL won't return the value Adam  
is after since it just executes the sql, no SELECT statements allowed.
