MySQL ERROR 1064 (42000) 通过 bash 脚本 (RHEL) 插入

MySQL 服务器：8.0.16 商业操作系统：RHEL 7.5

我编写了一个简单的脚本，将某些信息插入到数据库表中。

以下是我的脚本

# cat ~mysqldba/bin/connections.sh

   #!/bin/bash

log_file=~mysqldba/stats/connections_info.log


threads_connected=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf  -e "show global status like 'threads_connected';" | tr -d "| " | egrep -iv 'variable_name' | awk -F " " '{ print $2 }'`
echo "Number of open connections are ${threads_connected}." >> ${connections} 

threads_running=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf -e "show global status like 'threads_running';" | tr -d "| " | egrep -iv 'variable_name' | awk -F " " '{ print $2 }'`
echo "Number of connections that are not sleeping out of ${threads_connected} are ${threads_running}." >> ${connections} 

app1=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf --skip-column-names -e "select host from information_schema.processlist;" | grep 'ip-address1'| wc -l`

sleep_app1=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf --skip-column-names -e "select host from information_schema.processlist where command like 'sleep';" | grep 'ip-address1'|wc -l`

app2=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf --skip-column-names -e "select host from information_schema.processlist;" | grep 'ip-address2'| wc -l`

sleep_app2=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf --skip-column-names -e "select host from information_schema.processlist where command like 'sleep';" | grep 'ip-address2'|wc -l`

max_used_connections=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf  -e "show global status like 'max_used_connections';" | tr -d "| " | egrep -iv 'variable_name' | awk -F " " '{ print $2 }'`

max_used_connections_time=`/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf  -e "show global status like 'max_used_connections_time';" | tr -d "| " | egrep -iv 'variable_name' | awk -F " " '{ print $2 }'`

idle=`mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf --skip-column-names -e "select count(*) from information_schema.processlist where command='sleep';" | grep -v '+'`

/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf -e "insert into backup_info.connection_info (serial_no, run_date, run_time, total_number_of_connections, number_of_running_connections, no_of_connections_from_app27, no_of_sleeping_from_app27, no_of_connections_from_app28, no_of_sleeping_from_app28, max_used_connections, number_of_idle_connections) values (0, curdate(), curtime(), ${threads_connected}, ${threads_running}, ${app1}, ${sleep_app1}, ${app2}, ${sleep_app2}, ${max_used_connections}, ${idle})" 2>> ${log_file}

该脚本应该在每次运行时在数据库表中插入一行。

以下是数据库表：

CREATE TABLE `connection_info` (
  `SERIAL_NO` mediumint(9) NOT NULL AUTO_INCREMENT,
  `run_date` date DEFAULT NULL,
  `run_time` time DEFAULT NULL,
  `TOTAL_NUMBER_OF_CONNECTIONS` mediumint(9) DEFAULT NULL,
  `NUMBER_OF_RUNNING_CONNECTIONS` mediumint(9) DEFAULT NULL,
  `NO_OF_CONNECTIONS_FROM_APP1` mediumint(9) DEFAULT NULL,
  `NO_OF_SLEEPING_FROM_APP1` mediumint(9) DEFAULT NULL,
  `NO_OF_CONNECTIONS_FROM_APP2` mediumint(9) DEFAULT NULL,
  `NO_OF_SLEEPING_FROM_APP2` mediumint(9) DEFAULT NULL,
  `MAX_USED_CONNECTIONS` mediumint(9) DEFAULT NULL,
  `NUMBER_OF_IDLE_CONNECTIONS` mediumint(9) DEFAULT NULL,
  PRIMARY KEY (`SERIAL_NO`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci ROW_FORMAT=COMPRESSED

当我运行脚本时，它确实运行成功并在表中插入一行。

它确实在表中插入了一行，但是，当我在 crontab 中安排它时，当 crontab 执行它时，它会抛出一个错误，如下所示：

ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ', , 158, 158, 106, 106, , )' at line 1

如果我只是选择 INSERT 语句并在数据库上运行它，它确实会运行。如果我只是选择所有 mysql 命令并从命令行单独运行它，它确实会运行，唯一的问题是当我从crontab运行它时。

/mysql_binaries/mysql/bin/mysql --defaults-extra-file=/mysql_data/config/extra_options.cnf -e 'insert into backup_info.connection_info (serial_no, run_date, run_time, total_number_of_connections, number_of_running_connections, no_of_connections_from_app27, no_of_sleeping_from_app27, no_of_connections_from_app28, no_of_sleeping_from_app28, max_used_connections, number_of_idle_connections) values (0, curdate(), curtime(), 271, 3, 156, 156, 107, 107, 282, 269)

# perror 1064

我已经花了将近 3 天的时间，没有任何进展。
