How to learn ADO.Net Technology
After learning and using ADO.Net programming, the author summarizes the following three necessary steps, and the order of these three steps can never be changed. If ADO.Net technology finds that the order of the three steps is changed or missing in future programming, then your code must be wrong:
1. Use the connection method in the corresponding class to connect to the database. If you use the ADO.Net technology class, then use SqlConnection1 to establish a link to the database.
two。 Open this link.
3. Execute the command method in the corresponding class to specify the SQL statement to execute. If you use the SQLClient class, use SqlCommand to execute the specified SQL statement.
The two examples given below are code programmed with ADO.Net in .net. Because SQL Server is easier to use than Oracle, the database here uses Microsoft's SQL Server 2000. The reason is that it can be used directly without configuration after installation. Since you are accessing SQL Server, the class you use is, of course, the SQLClient class. These two examples are:
1. Add, delete, and modify data in the database.
two。 Use ADO technology to establish a database of ADO.Net technology.
