sed caused mit mysq 腳本 don bash jdb use mysql下刪除記錄較多的ssc源碼搭建會出現如下錯誤：企 娥:217 1793 408
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.
因此需要分批刪除表中數據，腳本如下：
#!/bin/bash
DB_USER="root"
DB_PASS="pw"
DB_HOST="10.228.221.25"
DB_NAME="tjxx"
echo "Sql start" >> /home/xxf/log.txt
timeS=date "+%Y-%m-%d"
echo "${timeS}" >> /home/xxf/log.txt
delete_sql="delete from region_stastics_history where time < ‘${timeS}‘ order by id limit 1000;"
#mysql -u$DB_USER -p$DB_PASS -h$DB_HOST -P${PORT} $DB_NAME -e "${delete_sql}"
count=0
while [ $count -le 500 ];do
echo $count >> /home/xxf/log.txt
mysql -u$DB_USER -p$DB_PASS -h$DB_HOST -P${PORT} $DB_NAME -e "${delete_sql}"
count=$((count + 1))
done
echo "Sql End" >> /home/xxf/log.txt
