Hey all, I asked this before (a while back) and have gotten some answers that solve my problem partially only.
------- old message ---------- I have a table with 205 columns. When an update statement updates a row in this table I want a trigger that creates a record of the old row in a separate table. The following works fine when not too many columns need to be written into the other table CREATE TRIGGER track_table BEFORE UPDATE ON table FOR EACH ROW BEGIN INSERT INTO table_track (value1,value2) VALUES (OLD.value1,old.value2); END; Is the any way of using OLD for all columns or generally another way of doing this. ------- old message ---------- One answer (thanks btw) suggested to do this: INSERT INTO table_track SELECT * FROM table WHERE key_col=OLD.key_col; This works fine, requires however that both tables have the same structure (nr of columns, order, etc). I would like to add an autoincrement ID and a timestamp to the record written by the trigger and do not want to have a timestamp field in the original table. Is there any other way of doing this? The only other idea I have (and I am not sure if this would even work) is to select the column headers from information_schema and loop through them building the actual insert statement.
