How to drop and re-populate mysql databases?
12,709
Solution 1
You might want to look at the options on mysqldump
such as --add-drop-database
and --add-drop-table
. I'd probably go for --add-drop-database
in this case.
Solution 2
1) take the dump
drop database db_name
create database db_name
mysql -u user -p db_name < dump.sql
I am sure this can be repeated any number of times. Its idempotent
Solution 3
From the MySQL console:
mysql> DROP DATABASE [dbName];
mysql> CREATE DATABASE [dbName];
mysql> USE [dbName];
mysql> SOURCE [pathToSQLDump];

I have a mysql database with 10 tables and need to drop and repopulate the database to run some performance tests. Using mysqldump, I can dump out the data. What steps should I follow next, to clear the database, and re-import? Will need to run this for different sizes of the database (i.e. tables with different number of rows) to calculate the db performance, so I need to make sure these steps can be replicated.
