我正在vb.net中构建一个vb.net查询:
cmd.CommandText = "Select id INTO @idDep from dBase.tableA where guid in (@strdepToDelete, @strOtherToDelete) and IsDependent = '1'; " & _

我想创建一个批处理文件来启动MySQL服务器(mysqld)和Rails瘦服务器(rails s thin)。但是只有MySQL启动,rails s thin没有:
@ECHO OFF
cd C:\path\to\app
CMD /C "mysqld --console"
REM exit <-- with or without it
REM cd C:\path\to\app <-- with or without it
CMD /C "rails s thin"
我还试图为此创建三个文件。主营的是另外两家。也没有帮助,只有MySQL运行。我需
我正在用powershell编写一个脚本,该脚本将连接到MySQL服务器,创建一个新数据库,然后对该数据库运行查询命令。我有一个预制的.sql文件,其中包含要执行的所有命令,但是我的代码似乎有一个问题,它实际上从来没有执行过.sql文件。任何帮助都将不胜感激。我的代码如下。
[void][system.reflection.Assembly]::LoadWithPartialName("MySql.Data")

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:
$sql = "
USE DB1;
DROP TRIGGER IF EXISTS my_trigger;
DELIMITER $$
CREATE TRIGGER my_trigger AFTER UPDATE ON tbl1
FOR EACH ROW BEGIN
INSERT INTO DB2.tbl2 (column1)
VALUES (1234);
END$$
DELIMITER ;
";
$cmd =
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。
例如,为了创建新用户,我想运行如下所示:
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'@'
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
今天,我启动了自定义的基于mysql-服务器映像的对接器容器,结果发现它没有运行我的CMD命令。直到今天都很好。这是Dockerfile:
