Disable console output when executing a SQL file using MySQL source command I begin by launching the MySQL command line tool:

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.
Here is the problem. The OS has two modes to print things


stdout
stderr


The --silent  only affects stdout. How do you nail stderr?

Try one of the following, and see if it works:

mysql --user=myusername --password=mypassword --silent --force -b 2&gt; nul
mysql --user=myusername --password=mypassword --silent --force -b --tee=nul


Give it a Try !!!

CAVEAT : I have dealt with something this before when answering a question about mysqldump : How to log verbose output from mysqldump?
