it tells me that the types aren't the same if i do this.  well, now that i 
typed that i tried it again, and it worked. . .  the first time i tried it, 
(the two tables have the same field names and types with the exception of 
this one field), i typed [insert into ap select * from ap3;] -- and it said 
that the types were not the same.  but just now i typed [insert into ap (. 
. .all field names listed individually. . .) select {all field names listed 
individually in the same order} from ap3], and it worked.  must be some 
limitation in the "select *" use. . .

thanks very much!  oh by the way, i haven't seen a camel in at least 12 
years either! (except on that perl book -- or is that a llama?).  i briefly 
looked at that site you recommended -- i think i could spend a while their 
later.

Should be simply

INSERT INTO ap (apnote)
SELECT ap3.apnote
FROM ap3;

You really shouldn't have single quotes, and the conversion to text is
supposed to be automatic.
