drops all tables of a specific db

mysql-drop-all-tables.sh

#!/bin/bash

#usage: mysql-drop-all-tables -d database -u dbuser -p dbpass

TEMP_FILE_PATH='./drop_all_tables.sql'

while getopts d:u:p: option
do
	case "${option}"
	in
	d) DBNAME=${OPTARG};;
	u) DBUSER=${OPTARG};;
	p) DBPASS=${OPTARG};;
	esac
done

echo "SET FOREIGN_KEY_CHECKS = 0;" > $TEMP_FILE_PATH
( mysqldump --add-drop-table --no-data -u$DBUSER -p$DBPASS $DBNAME | grep 'DROP TABLE' ) >> $TEMP_FILE_PATH
echo "SET FOREIGN_KEY_CHECKS = 1;" >> $TEMP_FILE_PATH
mysql -u$DBUSER -p$DBPASS $DBNAME < $TEMP_FILE_PATH
rm -f $TEMP_FILE_PATH

Thanks for the code! I modified slightly to:

• Support MariaDB's sudo style root access (no password)
• Avoid writing to a temp file

#!/bin/bash
echo \
  "SET FOREIGN_KEY_CHECKS = 0;" \
  $(mysqldump --add-drop-table --no-data "$@" | grep 'DROP TABLE') \
  "SET FOREIGN_KEY_CHECKS = 1;" \
| mysql "$@"

Usage remains similar:

mysql-drop-all-tables [-udbuser] [-pdbpass] database

I suggest simply using:

mysqldump --add-drop-table --no-data $DBNAME | grep 'DROP TABLE' | mysql --init-command="SET FOREIGN_KEY_CHECKS = 0;" $DBNAME

ommiting -u and -p as it is better to manage through .my.cnf or socket access
