Question

I have been looking for a way to duplicate a row, and insert it back to the table, but with a different id value (whose type is auto increment).

I could do this by specifying every column manually, but as there are many columns, and as the columns can be added or removed in the future, I want to use some easy query to do this without having to specify every column name.

Answer 1

Try this:

CREATE TEMPORARY TABLE temp_table SELECT * FROM source_table WHERE ...; 
ALTER TABLE temp_table DROP COLUMN column_with_auto_increment;
INSERT INTO source_table SELECT * from temp_table; DROP TABLE temp_table;
