INSERT INTO ON DUPLICATE KEY UPDATE -- Possible?

[gczychi]

Hi,

I'd like to INSERT new records, but only, when they not already exist. Otherwise I‘d need to update existing records.

There is a handy command in MySQL and I wonder if there’s a workaround for our SQL92 engine?

INSERT INTO table (column_list) VALUES (value_list) ON DUPLICATE KEY UPDATE c1 = v1, c2 = v2, ...;

Thanks a lot for your comments!
