C# and MySQL .NET Connector - Any way of preventing SQL Injection attacks in a generic class?

由 吃可爱长大的小学妹 提交于 2019-11-27 20:51:09
My idea is to create some generic classes for Insert/Update/Select via a C# (3.5) Winforms app talking with a MySQL database via MySQL .NET Connector 6.2.2. For example: public void Insert(string strSQL) { if (this.OpenConnection() == true) { MySqlCommand cmd = new MySqlCommand(strSQL, connection); cmd.ExecuteNonQuery(); this.CloseConnection(); } } Then from anywhere in the program I can run a query with/without user input by just passing a SQL query string. Reading around on SO is starting to give me the indication that this may lead to SQL injection attacks (for any user-input values). Is

No server-side prepared statements using MySQL Connector/J

由 梦想与她 提交于 2019-11-27 16:58:57
问题 From what I understand, MySQL 5.1 supports server-side prepared statements. Therefore the following code should prepare the statement once, and execute it 10 times: Connection conn = ds.getConnection(); PreparedStatement stmt = conn.prepareStatement("SELECT COUNT(*) FROM users WHERE user_id=?"); for (int i=0; i<10; i++) { stmt.setString(1, "FOO"+i); ResultSet res = stmt.executeQuery(); res.close(); } stmt.close(); conn.close(); What I see instead in the mysqld log is the query being executed

How do I setup ASP.NET MVC 2 with MySQL?

由 ＊爱你＆永不变心＊ 提交于 2019-11-27 02:46:28
Is it possible to setup ASP.NET MVC 2 to work with a MySQL database? I'm assuming that you have Visual Studio Professional 2008, have access to an instance of MySQL server, and have moderate to advanced development experience. This MAY work with VS2008 Web edition, but not at all sure. If you haven't, install MySQL Connector for .NET (6.2.2.0 at the time of this write-up) Optional: install MySQL GUI Tools If you haven't, install MVC 2 RTM , or better yet, use Microsoft's Web Platform Installer . ( UPDATE: MVC 2 has now been released for quite some time) Create an empty MySQL database. If you

How to connect to a MySQL Data Source in Visual Studio

由 倖福魔咒の 提交于 2019-11-26 22:28:29
I use the MySQL Connector/Net to connect to my database by referencing the assembly (MySql.Data.dll) and passing in a connection string to MySqlConnection . I like that because I don't have to install anything. Is there some way to "Choose Data Source" in Visual Studio 2010 without installing something? How can I get a MySQL option (localhost) to show up on one of these lists? Or do I have to install something? (I don't want to use ODBC btw) "Add Connection" from Server Explorer: Entity Data Model Wizard: Visual Studio requires that DDEX Providers (Data Designer Extensibility) be registered by
