How to log the error and warning while restoring the SQL dump on MySQL ?

Following are the steps we were doing.

mysql> CREATE DATABASE dbname;

mysql> USE dbname;

mysql> SOURCE dbdumpname.sql

Best Answer

To redirect MySQL errors and warnings to a log file, restore the SQL dump from bash not from a MySQL prompt.

mysql -u root -p db_name < dumpfilename.sql > /var/tmp/mysqldump.log 2>&1

If you need to supresss foreign key checks, create a shell script named mysql-import.sh and put the following contents in it:

#!/bin/bash

mysql -u root -p'password' -h hostname db_name << EOF

CREATE DATABASE dbname;
USE dbname;
SET foreign_key_checks=0;
SOURCE dbdumpname.sql;

EOF

Then chmod +x mysql-import.sh to make the script executable and run the script as,

./mysql-import.sh > /var/log/mysqldump.log 2>&1

This script will run the code that you were running in MySQL, but with the ability to redirect output to a log file, since it can be invoked from the shell.
