Best check your data types, and syntax. Either ID is somehow a string value, or
you are offering the wrong SQL syntax:

Yet another solution
SET ROWCOUNT 1
SELECT id FROM table ORDER BY id DESC
Only works if there is an index on id and the RDBMS support backward scans

Another solution :
For your query, try "SELECT MAX(id) FROM table"
That works with mysql.

Thanks I'll try your suggestion about the LIMIT portion, that's what I want,

program that opens a socket, connects to IRC chat and
The MAX(id) didn't return anything, i eventually settled for an idea posted
to
SELECT id FROM memodata ORDER BY id DESC
then take the first line value and ignore the rest. Ideally though i want
the last line with the highest id number. I know for a fact that another
INSERT won't happen before the S

Are you sure about that? Generally, MAX(id) _always_ returns something,
ie:
SELECT MAX(user_id) FROM user
This one will return the highest 'user_id' value, _or_ 0 if there are no
records in the 'user' ta

That should "work" with most databases, but what happens if there's a new
insert between the original insert and the SELECT statement above?
This _could_ be solved b
