Let us try to read all records from the table Registration.įollowing is an example program named H2jdbcUpdateDemo.
TRACCAR TUTORIAL UPDATE
In this example, we will write a program to update records. ID: 103, Age: 28, First: Sumit, Last: Mittal ID: 102, Age: 30, First: Zaid, Last: Khan ID: 101, Age: 25, First: Mahnaz, Last: Fatma Compile and execute the above program by executing the following commands in the command prompt. Save the above program into H2jdbcReadDemo.java. String sql = "SELECT id, first, last, age FROM Registration" Let us try to read all records from the table Registration.įollowing is an example program named H2jdbcRecordDemo. In this example, we will write a program for reading records. Save the above program into H2jdbcInsertDemo.java.
TRACCAR TUTORIAL REGISTRATION
Sql = "INSERT INTO Registration " + "VALUES(103, 'Sumit', 'Mittal', 28)"
Sql = "INSERT INTO Registration " + "VALUES (102, 'Zaid', 'Khan', 30)" Sql = "INSERT INTO Registration " + "VALUES (101, 'Mahnaz', 'Fatma', 25)"
String sql = "INSERT INTO Registration " + "VALUES (100, 'Zara', 'Ali', 18)" IDįollowing is an example program named H2jdbcInsertDemo. Let us insert the following records into the table Registration. In this example, we will write a program for inserting records. The above command produces the following output.Īfter this execution, we can check the table created using the H2 SQL interface. Save the above program into H2jdbcCreateDemo.java. String sql = "CREATE TABLE REGISTRATION " + ("Connecting to database.") Ĭonn = DriverManager.getConnection(DB_URL,USER,PASS) Static final String DB_URL = "jdbc:h2:~/test" Static final String JDBC_DRIVER = "org.h2.Driver" S.Noįollowing is an example program named H2jdbcCreateDemo. Consider a table named Registration having the following fields. In this example, we will write a program for create table. We can get this jar from the folder C:\Program Files (x86)\H2\bin.
TRACCAR TUTORIAL FULL
Step 4 − Executing a statement and receiving Resultset.īefore moving on to create a full program, we need to add h2-1.4.192.jar file to CLASSPATH. Step 1 − Registering the JDBC database driver.Ĭonnection conn = DriverManager.getConnection ("jdbc:h2:~/test", "sa","") Generally, there are five steps to create a JDBC connection.
TRACCAR TUTORIAL HOW TO
In this chapter, we will see how to create a JDBC connection with H2 database and the CRUD operations with the H2 database. We can interact with this database by using JDBC.
