- mysqldump 下载数据问题
由于权限不够，需要采用以下指令可以跨越权限
sudo mysqldump -u root -ppwd db --skip-lock-tables > ~/mysql.sql
5.如何source时不产生console output（控制台输出）
Disable console output when executing a SQL file using MySQL source command
mysql --user=myusername --password=mypassword --silent --force -b
The last -b option is used to disable beep on error.
Then I choose a database:
use Mydatabasename;
Then I execute SQL form a file like this:
source c:\x\y\z\myfile.sql
That's when things go slowly. I've executed part of the file before so the console is filled with duplicate row errors which slow execution badly. I get 5-10 statements executed per second. Without duplicate rows the code executes tens of thousands of statements (30k+) every 5 seconds.
I need to do this since the file is large and I can't execute it in one go.
