错误处理选项
-f, --force 强制执行sql -v, --verbose 显示更多信息 --show-warnings 显示警告信息 这三个经常是一起使用的
如果执行脚本有错，可以使用 -f 强制执行，而不是在遇到错误时直接终止
sql测试文本 [root@db02 ~]# cat a.sql insert into stu values(1); insert into stu values(2aa); insert into stu values(3);遇到错误直接终止运行
[root@db02 ~]# mysql -uroot -p123 test < a.sql ERROR 1054 (42S22) at line 2: Unknown column '2aa' in 'field list' [root@db02 ~]# mysql -uroot -p123 test -e 'select * from stu' Warning: Using a password on the command line interface can be insecure. +------+ | id | +------+ | 1 | +------+使用 -f 参数
