ShareThe Java Database Connectivity (JDBC) API is the industry standard for database-independent connectivity between the Java programming language and a wide range of databases SQL databases and other tabular data sources, such as spreadsheets or flat files. The JDBC API provides a call-level API for SQL-based database access. The PreparedStatement interface is a subinterface of Statement. It is used to execute parameterized query. Let's see the example of parameterized query: String sql="insert into emp values (?,?,?)"; As you can see, we are passing parameter (?) for the values. Its value will be set by calling the setter methods of PreparedStatement. 1. This JDBC API interface is used for static SQL statements at run time. The PreparedStatement interface is used for dynamic SQL statements at run time. 2. There is no specific protocol in Statement interface. The PreparedStatement used the non sql binary protocol. 3. The Statement interface does not allow accepting parameters at runtime.Sep 22, 2014 · Beginning Java 8 APIs, Extensions and Libraries completes the Apress Java learning journey and is a comprehensive approach to learning the Java Swing, JavaFX, Java Scripting, JDBC and network programming APIs.This book covers the key extensions of the Java programming language such as Swing, JavaFX, network programming, and JDBC.
