Question

Does mysqldump (or some other command) have an option to dump ONLY recently updated rows? I haven’t been able to find anything in the docs about this. thx.

Answer 1

You can give mysqldump a where clause using the –where option. So if you have a column called “modified” in your table and you want all rows modified in the past 2 hours you could do something like this:

mysqldump my_schema my_table --where="modified > now() - interval 2 hour"
