procedure and provide parameters (if the stored procedure has parameters; in general, SQL statements need to transmit the executed statement string to the database server, which is longer than the stored procedure to the database server;3) high security. Assigning values to Stored Procedure parameters can only be passed through question marks (this can be reflected through the following JDBC call example f

affected to a certain extent; It is difficult to change the data source: JDBC supports multiple databases, and operations between different databases must be different, which makes it very difficult to change the data source. 2. process and principle of connecting to the database through JDBC 1,Load the driver of the specified database in the development environment.

1. Preface Database applications are often used in many software systems and are indispensable for developing large systems. However, if the database resources are not well managed (for example, resources such as the database cursors (resultset), statement, and connection) are not recovered in time), system stability is often directly caused. This type of instability is not only caused by the database or the system itself. It will be gradually reveal

Write these parts separately in a class, connect to a specific database based on input parameters such as driver, URL, user, and password.
