MySqlHelper 是一个封装了常用数据库操作的工具类,它提供了一系列的方法来简化与 MySQL 数据库的连接、查询、插入、更新和删除操作。通过使用 MySqlHelper,开发者可以更加专注于业务逻辑,而不必在每个模块中重复编写大量的数据库代码。 MySqlHelper 的基本结构 首先,让我们定义一个基本的 MySqlHelper 类。这个类将会包...
pip install mysqlhelper 1. 连接到数据库 在进行数据库查询之前,我们需要先连接到数据库。首先,导入MySQLHelper库: importmysqlhelper 1. 然后,创建一个MySQLHelper对象,并传入数据库连接参数: db=mysqlhelper.MySQLHelper(host='localhost',user='username',password='password',database='dbname') 1. 在这个示例...

MySqlHelper: MySqlHelper里面的方法和SqlHelper差不多,就不一一说明了。 除此之外引用DBUTILITY类库也是一个很好的选择,DBUTILITY.DLL是一个集成SQLHELPER、MYSQLHELPER以及ORACLEHELPER等众多数据库操作类的类库,添加引用后就可以直接调用其中方法对数据库进行查询、编辑等操作,十分的方便。

Create a clean .NET 8 Console application, with Mysql.Data 8.3.0. Code: using MySql.Data.MySqlClient; var reader = await MySqlHelper.ExecuteReaderAsync( "SERVER=localhost;PORT=3306;DATABASE=DB;UID=root;PASSWORD=PWD", "SELECT * FROM Table WHERE id = @id", new MySqlParameter("@id", 42)...
Description:You can call MySqlHelper.ExecuteReader() either with a MySqlConnection parameter or with string parameter containing the connection-string. In the latter case ExecuteReader should create an connection itself. Since 6.3.5 this does not work anymore, reverting to 6.3.4 solves the problem....
I would like to be able to set it on the MySqlHelper directly, as that saves me from creating my own MySqlCommand, which I have so far been able to avoid. Is there a way to do that which I have missed? Alternatively, is there a way of setting the CommandTimeout for the whole of...
