tables=$(mysql-h$host_name-u$user_name-p$user_pwd$database-A-Bse"showtables")
fortable_namein$tables
do
check_result=$(mysql-h$host_name-u$user_name-p$user_pwd$database-A-Bse
"checktable$table_name"|awk'{print$4}')
if["$check_result"="OK"]
then
echo"It'snoneedtorepairtable$table_name"
else
echo$(mysql-h$host_name-u$user_name-p$user_pwd$database-A-Bse
"repairtable$table_name")
fi
#优化表,可提高性能
