MySQL 查詢不是從 bash 執行的，而是從 MySQL 客戶端工作的

使用免費 16。

MySQL 查詢從 bash 失敗，但可以從 MySQL 客戶端工作：

   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}"

執行 bash 腳本後出現以下錯誤：

   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 客戶端（HeidiSQL）中執行列印的 MySQL 查詢，它工作正常：

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. */

請告知如何修復它。

解決方案

正如@yoonix 指出的那樣，是的，缺少 -e 選項。

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

現在效果很好。謝謝您的幫助！

我不是 100% 確定 collat​​e utf8_hungarian_ci 部分，但我能夠通過省略反斜杠和刻度，將創建數據庫行更改為：

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;

並在此處添加 -se：

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