注意
--auto-rehash Enable automatic rehashing. One doesn't need to use
'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
(Defaults to on; use --skip-auto-rehash to disable.)
2.临时使用
# mysql -u root -p --auto-rehash
会有提示,可以不理睬
切换到数据库
数据库,然后调用tab键测试吧
注意:自动补全是客户端命令,必须切换到数据库下才能使用
