MySQL 查询不是从 bash 执行的，而是从 MySQL 客户端执行的

MySQL 查询不是从 bash 执行的，而是从 MySQL 客户端执行的

使用 UBUNTU 16。

MySQL 查询在 bash 中失败，但在 MySQL 客户端中可以运行：

    query=$(cat << EOF
CREATE DATABASE \`${mysql_local_database}\` /*!40100 COLLATE \'utf8_hungarian_ci\' */; use \`${mysql_local_database}\`; GRANT SELECT, EXECUTE, SHOW VIEW, ALTER, ALTER ROUTINE, CREATE, CREATE ROUTINE, CREATE TEMPORARY TABLES, CREATE VIEW, DELETE, DROP, INDEX, INSERT, REFERENCES, UPDATE, LOCK TABLES  ON \`${mysql_local_database}\`.* TO 'myuser'@'%'; FLUSH PRIVILEGES;
EOF
)
echo $query
mysql -u ${mysql_local_user} -p${mysql_local_pass} -h localhost "${query}"

执行 bash 脚本后出现以下错误：

    CREATE DATABASE `mydb` /*!40100 COLLATE 'utf8_hungarian_ci' */; use `mydb`; GRANT SELECT, EXECUTE, SHOW VIEW, ALTER, ALTER ROUTINE, CREATE, CREATE ROUTINE, CREATE TEMPORARY TABLES, CREATE VIEW, DELETE, DROP, INDEX, INSERT, REFERENCES, UPDATE, LOCK TABLES ON `mydb`.* TO 'user'@'%'; FLUSH PRIVILEGES;
ERROR 1102 (42000): Incorrect database name 'CREATE DATABASE `mydb` /*!40100 COLLATE 'utf8_hungarian_ci' */'

如果我在 MySQL 客户端（HeidiSQL）中执行打印的 MySQL 查询，它可以正常工作：

CREATE DATABASE `mydb` /*!40100 COLLATE 'utf8_hungarian_ci' */; use `mydb`; GRANT SELECT, EXECUTE, SHOW VIEW, ALTER, ALTER ROUTINE, CREATE, CREATE ROUTINE, CREATE TEMPORARY TABLES, CREATE VIEW, DELETE, DROP, INDEX, INSERT, REFERENCES, UPDATE, LOCK TABLES ON `mydb`.* TO 'myuser'@'%'; FLUSH PRIVILEGES;

/* Affected rows: 1  Found rows: 0  Warnings: 0  Duration for 4 queries: 0,000 sec. */

请告知如何修复。

解决方案

正如@yoonix 指出的那样，是的，缺少了 -e 选项。

mysql -u ${mysql_local_user} -p${mysql_local_pass} -h localhost - e "${query}"

现在运行良好。谢谢您的帮助！

我不是 100％ 确定 collat​​e utf8_hungarian_ci 部分，但我能够通过省略反斜杠和勾号，将创建数据库行更改为：来让它创建数据库而不会出现错误：

CREATE DATABASE $mysql_local_database  /*!40100 COLLATE utf8_hungarian_ci */ ; use $mysql_local_database ; GRANT SELECT, EXECUTE, SHOW VIEW, ALTER, ALTER ROUTINE, CREATE, CREATE ROUTINE, CREATE TEMPORARY TABLES, CREATE VIEW, DELETE, DROP, INDEX, INSERT, REFERENCES, UPDATE, LOCK TABLES ON $mysql_local_database.* TO 'myuser'@'%'; FLUSH PRIVILEGES;

并且在这里添加了 -se：

mysql -u ${mysql_local_user} -p${mysql_local_pass} -h localhost -se "${query}"
