How can i dump blob fields from mysql tables

问题

i am trying to dump the BLOB fields from mysql table.

but when i dumping blob records using sqlYog am getting unvaluable data.

How can i backup BLOB type fields?

Note:

BLOB field has image.

回答1:

The official mysqldump utility can dump BLOBs fields without any problem, use -q or --opt when you run the backup.

So for example to backup images_table that contains image in BLOB format :

mysqldump --opt -u user -ppass dbname images_table > images.sql

回答2:

the parameter --hex-blob is useful when you intent to import it to another DB like sqlite.
