thanks, exactly what I was looking for. I used this to replace my WordPress database.

Had to put the table name in quotes in the for loop:

$MYSQL -u $MUSER -p$MPASS $MDB -e “drop table \`$t\`”

Call me paranoid, but I don't like to put my database password in scripts. So I replaced the definition of MPASS with

read -s -p "Your database password: " MPASS

To empty the database in MySql just go to the database and select the all tables (checkbox on of all tables) then select the “empty” action just down from the table names, then click “GO” button just right side of action selected .

This worked perfecly. Save me the monotony of deleting 300+ tables from a Magento Install

You should disable FOREIGN_KEY_CHECKS. I like Lon F. Binder solution.

I like this even more.

echo “select concat(‘drop table ‘, table_name, ‘;’) from information_schema.tables where table_schema=schema()” | mysql CONNECT | grep “^drop table ” | mysql CONNECT

Make sure you connect to the right schema :p

I agree with Romina

I followed it and ended with completely deleting the database and not just the tables!! Your post title is absolutely incorrect. Please change it..

EVERYONE BE CAREFUL WHILE DOING THIS

A little longer, but also a little more efficient because it does the drop (of all tables) in one shot:


mysql --user=YOUR_USERNAME --password=YOUR_PASSWORD -BNe "show tables" YOUR_DBSCHEMA_NAME | tr '\n' ',' | sed -e 's/,$//' | awk '{print "SET FOREIGN_KEY_CHECKS = 0;DROP TABLE IF EXISTS " $1 ";SET FOREIGN_KEY_CHECKS = 1;"}' | mysql --user=YOUR_USERNAME --password=YOUR_PASSWORD  YOUR_DBSCHEMA_NAME

You can use also:
mysql> use database;
mysql> truncate tablename;
to empty a table!

What about :
mysqldump -u[user] -p[ssht...] --add-drop-table --no-data [DATABASE] | grep ^DROP | mysql -u[user] -p[sshht...] [DATABASE]
