databases. So how to access the MySQL (the best combination with PHP) database in. NET? Maybe many people will immediately say: OLEDB is used, but it is actually used. NET OleDb Data Provider cannot access MySQL (the best combination with PHP). If you use it, the System will prompt you: "Net Data ole db Provider (System. data. odbc) does not support MSDASQL prov

){ESErrPrintComError (e );}} Summary Integration of database access in the document, view, and framework architecture is not difficult in general. Microsoft provides many sample codes. Most of the work is to rewrite the sample code from other languages to VC. The main task is to understand the documentation, views, an

Cross-database server, cross-instance access is a more common way of access, in Oracle can be achieved through the way of DB link. For MySQL, there is a federated storage engine that corresponds to it. It is also a way to access data on a remote server by creating a link form. This article briefly describes the federat

specific steps for ODBC creation can refer to the ODBC Connection database data source for C # programming. After the ODBC is created successfully, you can click Test Connection, which will prompt the connection to succeed, as shown in.C # Development?? This paper provides a class for adding and deleting Kingbase via ODBC interface, which is normal in Win7/win 10 test. source Code and database download?? I

counter exceeds 95%, the bottleneck is the CPU. You can consider adding a processor or changing a faster processor. 3.% privileged time indicates the percentage of idle processor time used in privileged mode. (Privileged mode is a processing mode designed for operating system components and operating hardware drivers. It allows direct access to hardware and all memory. Another mode is the user mode. It is a finite processing mode designed for applica

Public Gateway Interface CGI (Common gateway Interface)CGI is a technology that is implemented earlier. Applicable to a variety of server platforms, such as UNIX, Windows, but CGI development costs, maintenance difficul

the ODBC Data Source. Basically, you can use MySQLDriverCS to connect to MySQL. MySQLDriverCS is a project on SourceForge. NET, but I don't know why. This website cannot be accessed in China. The following is a sample code using MySQLDriverCS: The code above is almost identical. The difference is that Odbc is changed to MySQL. In addition, note that the ExecuteReader method of Command is changed to ExecuteReaderEx in MySQLDriverCS, for more details a

When I first made a web page, I experienced a lot of ups and downs, because the website construction is different from the development of common programming languages. For example, in Java, you only need to install JDK and download an integrated development environment such as eclipse to start development. However, the development of websites involves multiple languages and multiple software. Therefore, it is really scratching your head at the beginning. However, if you can make a good arrangeme

When we connect to the database and make the query we want, we can show them on the Web page. Using DataReader is a better choice for saving server resources. DataReader provides a read-only, forward-only way of accessing data, so DataReader is perfect for accessing more complex data, or just trying to show some data. DataReader is an abstract class and cannot be instantiated directly, and is created by the ExecuteReader method of the Command object

(the best combination with PHP) DriverCS, it is "abandoned by the owner". There are still some stories. Fortunately, we have other options. Here we will introduce two methods to access the MySQL database. Use ODBC. NET ODBC. NET stands for ODBC. NET Data Provider: It requires that MDAC 2.7 or later has been installed on the system. In addition, you also need to install the ODBC driver for MySQL (the best c

Introduction if you have worked in a large group of companies, you will have the opportunity to access MySQL, although it does not support transaction processing, stored procedures, however, the functions provided by MySQL can satisfy most of your needs. In addition, simple MySQL has some unique advantages. In some cases, it is faster than large databases. So how to access the MySQL
