and processing data in a data source usingthe Java<sup><font size=-2>TM</font></sup> programming language. This API includes a framework whereby differentdrivers can be installed dynamically to access different data sources.<P>The <code>java.sql</code> package, referred to as the JDBC 2.0 core API, had many new features added in the Java<sup><font size=-2>TM</font></sup> 2 SDK, Standard Edition, version 1.2 release. New methods, fields, constructors, and exceptions in the JDBC 2.0 API are marked "Since 1.2" in the javadoc comments.<P>The class <code>SQLPermission</code> was added in theJava<sup><font size=-2>TM</font></sup> 2 SDK, Standard Edition, version 1.3 release. This class is used to prevent unauthorizedaccess to the logging stream associated with the <code>DriverManager</code>,which may contain information such astable names, column data, and so on.<p><h2><a name="2.0 API">What Is in the JDBC<sup><font size=-2>TM</font></sup> 2.0 API</a></h2><P><B>NOTE:</B> Code that uses API marked "Since 1.2" must be run using a JDBC technology driver that implements the JDBC 2.0 core API. Check yourdriver documentation to be sure that it implements the particular features you want to use.<P>The JDBC<sup><font size=-3>TM</font></sup> 2.0 API includes the complete JDBC API, which includes both core and Optional Package API,and provides industrial-strength databasecomputing capabilities. It is not, however, limited to SQL databases;the JDBC2.0 API makes it possible to access data from virtually any datasource with a tabular format. ⌨️ 快捷键说明
