I have a database (myDB) that holds some tables. During my backup process I have one of those tables that should be filtered. So I want to backup only a subset of rows inside table1, when I backup the entire database.

I am using mysqldump like this:

mysqldump -uUSER -pPASSWORD --routines --add-drop-database   --databases myDB --tables table1 -w "id<3"> myDB_BK.sql

The subset rows is correct for table1 but I dont have the entire database. Only the specified table1.

I've tried all combination with no success.

Any Idea in how to accomplish this task?

Dumping subsets of table data can only be done backing up individual tables.

I once answered a post entitled Is it possible to mysqldump a subset of a database required to reproduce a query?. In that post, I used mysqldump strictly against the tables in question.

The only thing you can do is to produce two dumps

  • mysqldump of the database without table1 (means you have to name all other tables (See my old post How do you mysqldump specific table(s)?)
  • mysqldump only table1 using -w or --where
  • concatenate the second dump to the first dump

Give it a Try !!!
