        3 ) mysql -u root -p123456789 -e 'USE eventime;DELETE FROM eventime.dt WHERE date1 <(SELECT STR_TO_DATE(CONCAT(DATE_FORMAT(now(),\'%Y-%m-%d\'),\'-1\'),\'%Y-%m-%d\')- INTERVAL 90 DAY);' ;;

        0 ) Ctrl+Z ;;
        * ) echo "Please enter 1, 2, 3 , 4 or 0"
    esac

Answer 1

在下面的部分中将'更改为'，如下所示;

3 ) mysql -u root -p123456789 -e "USE eventime;DELETE FROM eventime.dt WHERE date1 <(SELECT STR_TO_DATE(CONCAT(DATE_FORMAT(now(),'%Y-%m-%d'),'-1'),'%Y-%m-%d')- INTERVAL 90 DAY);" ;;

Answer 2

您只需在日期格式中使用"和其他参数：

3 ) mysql -u root -p123456789 -e 'USE eventime;DELETE FROM eventime.dt WHERE date1 <(SELECT STR_TO_DATE(CONCAT(DATE_FORMAT(now(),"%Y-%m-%d"),"-1"),"%Y-%m-%d")- INTERVAL 90 DAY);' ;;
