MUSER="$1"

MPASS="$2"

# 设置命令路径

MYSQL=$(which mysql)

AWK=$(which awk)

GREP=$(which grep)

# help

if [ ! $# -ge 3 ]

then

echo "Usage: $0 {MySQL-User-Name} {MySQL-User-Password} {MySQL-Database-Name} [host-name]"

echo "Drops all tables from a MySQL"

exit 1

# 连接mysql数据库

if [ $? -ne 0 ]

then

echo "Error - 用户名或密码无效，无法连接mysql数据库"

exit 2

fi

# make sure tables exits

if [ "$TABLES" == "" ]

then

echo "Error - 在数据库中 $MDB 未发现相关表"

exit 3

fi

# let us do it

for t in $TABLES

do

echo "Deleting $t table from $MDB database..."

$MYSQL -u $MUSER -p$MPASS -h $MHOST $MDB -e "drop table $t"
