Como escapar um - em um nome de tabela no mysqldump

Question

Se eu quiser excluir uma tabela em um esquema que contenha menos - , como faço para escapar disso no mysqldump? Ou eu não preciso?

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

parece não funcionar

    

Answer 1

Por MySQL :: MySQL 5.7 Manual de Referência :: 5.5.4 mysqldump - Um programa de backup de banco de dados

Tente seguir:

mysqldump --ignore-table=database.table1

    

Answer 2

Nenhum escape especial é necessário:

Answer 3

Você normalmente escapa um hífen - com aspas, então eu esperaria que o seguinte funcionasse:

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