How to escape a - in a table name in mysqldump

  • 772

If I want to exclude a table in a schema which contains a minus -, how do I escape that in mysqldump? Or do I not need to?

mysqldump --ignore-table=foo-bar.tl_log

does not seem to work

mysql

  1. No special escaping is needed:

  2. You normally escape a hyphen - with quotes so I would expect the following to work:

    mysqldump --ignore-table='foo-bar.tl_log'

    Per MySQL :: MySQL 5.7 Reference Manual :: 5.5.4 mysqldump — A Database Backup Program

    Try following:

    mysqldump --ignore-table=database.table1
