Cannot insert into Cassandra table, getting SyntaxError - cassandra

Question

I have an assignment where I have to build a Cassandra database. I have connected Cassandra with IntelliJ, i'm writing in java and the output is shown in the command line.
My keyspace farm_db contains a couple of tables in wish i'm would like to insert data. I would like to insert the data with two columns and a list all in one row, in the table 'farmers'. This is a part of my database so far:
cqlsh:farm_db> use farm_db;
cqlsh:farm_db> Describe tables;
farmers foods_dairy_eggs foods_meat
foods_bread_cookies foods_fruit_vegetables
cqlsh:farm_db> select * from farmers;
farmer_id | delivery | the_farmer
-----------+----------+------------
This is what i'm trying to do:
[Picture of what i'm trying to do][1]
I need to insert the collection types 'list' and 'map' in 'farmers' but after a couple of failed attempts with that I tried using hashmap and arraylist instead. I think this could work but i seem to have an error in my syntax and I have no idea what the problem seem to be:
Exception in thread "main" com.datastax.driver.core.exceptions.SyntaxError: line 1:31 mismatched input 'int' expecting ')' (INSERT INTO farmers (farmer_id [int]...)
Am I missing something or am I doing something wrong?
This is my code:
public class FarmersClass {
public static String serverIP = "127.0.0.1";
public static String keyspace = "";
//Create db
public void crateDatabase(String databaseName) {
Cluster cluster = Cluster.builder()
.addContactPoints(serverIP)
.build();
keyspace = databaseName;
Session session = cluster.connect();
String create_db_query = "CREATE KEYSPACE farm_db WITH replication "
+ "= {'class':'SimpleStrategy', 'replication_factor':1};";
session.execute(create_db_query);
}
//Create table
public void createFarmersTable() {
Cluster cluster = Cluster.builder()
.addContactPoints(serverIP)
.build();
Session session = cluster.connect("farm_db");
String create_farm_table_query = "CREATE TABLE farmers(farmer_id int PRIMARY KEY, the_farmer Map <text, text>, delivery list<text>); ";
session.execute(create_farm_table_query);
}
//Insert data in table 'farmer'.
public void insertFarmers(int id, HashMap< String, String> the_farmer, ArrayList <String> delivery) {
Cluster cluster = Cluster.builder()
.addContactPoints(serverIP)
.build();
Session session = cluster.connect("farm_db");
String insert_query = "INSERT INTO farmers (farmer_id int PRIMARY KEY, the_farmer, delivery) values (" + id + "," + the_farmer + "," + delivery + ");";
System.out.println(insert_query);
session.execute(insert_query);
}
}
public static void main(String[] args) {
FarmersClass farmersClass = new FarmersClass();
// FarmersClass.crateDatabase("farm_db");
// FarmersClass.createFarmersTable();
//Collection type map
HashMap<String, String> the_farmer = new HashMap<>();
the_farmer.put("Name", "Ana Petersen ");
the_farmer.put("Farmhouse", "The great farmhouse");
the_farmer.put("Foods", "Fruits & Vegetables");
//Collection type list
ArrayList<String> delivery = new ArrayList<String>();
String delivery_1 = "Village 1";
String delivery_2 = "Village 2";
delivery.add(delivery_1);
delivery.add(delivery_2);
FarmersClass.insertFarmers(1, the_farmer, delivery);
}

Answer 1

The problem is the syntax of your CQL INSERT query:
String insert_query = \
"INSERT INTO farmers (farmer_id int PRIMARY KEY, the_farmer, delivery) \
values (" + id + "," + the_farmer + "," + delivery + ");";
You've incorrectly added int PRIMARY KEY in the list of columns.
The correct format is:
INSERT INTO table_name (pk, col2, col3) VALUES ( ... )
For details and examples, see CQL INSERT. Cheers!
