Limiting the number of records from mysqldump?

Question

I am trying to load a small sample of records from a large database into a test database.

How do you tell mysqldump to only give you n records out of 8 million?

Answer 1

If you want to get n records from a specific table you can do something like this:

mysqldump --opt --where="1 limit 1000000" database table > dump.sql

This will dump the first 1000000 rows from the table named table into the file dump.sql.
