FW: simple? query

Hi,

Thanks for the suggestion, the only problem is, if primary key is used then each row should be unique what is not true; since I have a column 'registered' what only can be 1 or 0...

Regards,

Jan

Something along the lines of:

| UPDATE table SET attribute = 'something' WHERE primary_key = 'id';
| INSERT INTO table (primary_key, attribute) SELECT 'id', 'something' WHERE 'id' NOT IN (SELECT primary_key FROM table);

should achieve that.
