mysqldump table without dumping the primary key

Question

I have one table spread across two servers running MySql 4. I need to merge these into one server for our test environment.

These tables literally have millions of r

Answer 1

if you don't care what the value of the auto_increment column will be, then just load the first file, rename the table, then recreate the table and load the second file. finally, use

INSERT newly_created_table_name (all, columns, except, the, auto_increment, column)
       SELECT all, columns, except, the, auto_increment, column
         FROM renamed_table_name
