mysql - 使用 like 和 % 的 SQL 错误

Question

我的脚本旨在循环遍历环境、访问数据库并检查是否有任何名字/姓氏组合具有关联的用户 ID。我不确定为什么会收到下面列出的错误。

#/bin/bash

#specify user to search for  *******DO NOT PUT SPACE, ie. jaylefler
echo "Please enter user first name: "
read first_name

echo "Please enter user last name: "
read last_name

echo "Please enter LDAP User ID: "
read ldapuser

echo "Please enter LDAP password: "

stty -echo

read ldappw

stty echo
#logs to write output to
log="ui_${username}_access.log"
finallog="${username}_ui_access.txt"

#create file if not exist, else null it
[[ -f ${log} ]] && cat /dev/null > ${log} || touch ${log}
[[ -f ${finallog} ]] && cat /dev/null > ${finallog} || touch ${log}

#log it all
{

echo "environment"
sshpass -p $ldappw ssh $ldapuser@54.123.777.567 'mysql -h host -u user -    ppassword database -e \
"select user_id from users where first like "%'${first_name}'%" and last like "%'${last_name}'%";"'


} > $log

当我执行脚本时，我收到以下错误:

Please enter user first name: 
jay
Please enter user last name: 
lefler
Please enter LDAP User ID: 
jlefler
Please enter LDAP password: 
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 '%jay% and last like %lefler%' at line 1
jlefler@ubuntu:~/Desktop$ 

Answer 1

我不太熟悉这种类型的脚本，但在我看来，围绕 %jay% 和 %lefler% 需要引号，以便 SQL 显示为:

select user_id from users where first like '%jay%' and last like '%lefler%';
