Lesson 3:Executing SQL Statements

Objectives

• Define tables in a database using JDBC• Add new rows to a table using JDBC• Perform queries on a database using JDBC• Extract data from a ResultSet object• Describe the purpose of transactions• Use transactions to maintain data consistency

TheStatement Interface

• Statement interface methods• executeUpdate• executeQuery

TransactionsUsing SQL Statements

• Allow you to group statements so that changes do not take effect until both tables are updated

Summary

Define tables in a database using JDBC Add new rows to a table using JDBC Perform queries on a database using JDBC Extract data from a ResultSet object Describe the purpose of transactions Use transactions to maintain data consistency
