Question :
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?
Answer :
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 !!!
