Java – datastex querybuilder insert statement

What is the correct way to build insert statements using querybuilder from datastex Java driver for Cassandra

I'm using Cassandra 2 X and Java driver 2.0 0-rc1

I know I can use prepared statements to achieve the same goal, but I look forward to using query builder

@Test
public void testTableInsert() {
    Insert insert = QueryBuilder
            .insertInto(KEYSPACE_NAME,TABLE_NAME)
            .value("username","jdoe")
            .value("first","John")
            .value("last","Doe");
    System.out.println(insert.toString());
    ResultSet result = session.execute(insert.toString());
    System.out.println(result);

}

I can confirm that the query string is valid because it succeeds when it is manually attempted on cqlsh

INSERT INTO test.user(username,first,last) VALUES ('jdoe','John','Doe');

The error reported by the driver is

Solution

You just forgot to create the key space

It is used to create KS, create CF and insert the complete code of partition using querybuilder

public static void main(String[] Args)
{
    Cluster cluster = null;
    cluster = Cluster.builder()
                     .addContactPoint("127.0.0.1")
                     .build();
    Session session = cluster.connect();

    try
    {
        String createKS = "CREATE KEYSPACE test WITH REPLICATION = { 'class': 'SimpleStrategy','replication_factor': '2' }";
        session.execute(createKS);
        String query = "create table test.user (username text primary key,first text,last text);";
        session.execute(query);

        System.out.println("insert executed");
        Insert insert = QueryBuilder.insertInto("test","user")
                                    .value("username","jdoe")
                                    .value("first","John")
                                    .value("last","Doe");
        System.out.println(insert.toString());
        ResultSet result = session.execute(insert.toString());
        System.out.println(result);
    }
    catch (Exception ex)
    {
        ex.printStackTrace();
    }

    System.exit(0);
}
