我正在vb.net中构建一个vb.net查询:

我试图通过python管道运行mysql命令。
cmd='CREATE DATABASE {0} ; GRANT ALL PRIVILEGES ON {1}.* TO "{2}"@"%" identified by password "{3}";'.format(requested_database_name,requested_database_name,'xyz',requested_password)
其中密码是从mysql生成的散列。我总能得到

在安装过程中,我需要创建新的MySQL用户、新数据库并从转储文件中填充它。我的问题是如何从命令行(cmd,Windows)执行此操作?我的意思是,我从某个脚本调用cmd,它可以以根权限启动mysql命令行客户端,但我不能将参数传递给mysql外部表单。

cmd /c mysql -u root -p GRANT ALL ON *.* TO 'newuser'@'localhost' IDENTIFIED BY 'pass';
有可能吗?要传递*“请全部打开。将'newuser'@'
我需要在命令行中创建mysql触发器。
此sql在mysql控制台中运行良好:

在我的vb.net控制器中的代码:
For i = 0 To depToDelete.Count - 1
cmd.CommandText = "delete from budget.budget_monthlybudgetfees where guid in(@strdepToDelete, @strOtherToDelete);"
cmd.Parameters.Add("@strdepToDelete", MySql.Data.MySqlClient.MySqlDbType.VarChar, 36).Value = depToDelete
问题:I有一个运行以下更新的mySql存储过程:
IF target = 'sup' THEN
UPDATE my_table SET deleted = 1, last_updated = lastUpdate WHERE id = ID AND user_id = accountID;
END IF;
输入参数如下:
(IN ID BIGINT, IN lastUpdate DATETIME, IN target VARCHAR(3), IN accountID BIGINT)
当调用这个sproc时,mySql更新user_id表中的所有行,并且似乎忽略WHERE
