Triggers 用户端的特定主机

目前我有一个像这样的主机的mariadb用户

'userdb'@'10.148.0.0/255.255.240.0'

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, REFERENCES, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER ON *.* TO 'userdb'@'10.148.0.0/255.255.240.0' IDENTIFIED BY PASSWORD '*21E60721C392B0B98F8E387DDA480376C04B42B5'

TRIGGER command denied to user 'userdb'@'10.148.0.0/255.255.240.0' for table 'tclmuser'

格兰特就这样

'userdb'@'10.148.0.0/255.255.240.0'

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, REFERENCES, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER ON *.* TO 'userdb'@'10.148.0.0/255.255.240.0' IDENTIFIED BY PASSWORD '*21E60721C392B0B98F8E387DDA480376C04B42B5'

TRIGGER command denied to user 'userdb'@'10.148.0.0/255.255.240.0' for table 'tclmuser'

但当我们从应用程序中得到这样的错误消息时

'userdb'@'10.148.0.0/255.255.240.0'

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, REFERENCES, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, EVENT, TRIGGER ON *.* TO 'userdb'@'10.148.0.0/255.255.240.0' IDENTIFIED BY PASSWORD '*21E60721C392B0B98F8E387DDA480376C04B42B5'

TRIGGER command denied to user 'userdb'@'10.148.0.0/255.255.240.0' for table 'tclmuser'

然后我检查触发器中的定义者是否与用户相同。

所以这个问题来自于用户处的主机？

我不知道我见过主机/子网表单中指定的主机。通常是.me中所示示例之一的一种形式，只要我知道这样指定的主机

192.168.%.%
