Question

Alright, so I’m trying to store data in Sqlite. So I’m trying to store the id of the user with the a “line”. Yet, it seems that the where clause is failing me.

    String query = "SELECT * FROM Users WHERE username='Fellixombc";
    ResultSet result = this.sqlStatement.executeQuery(query);
    int userId = 0;
    while(result.next()) {
        System.out.println("TRUE");
        userId = result.getInt("id");
        System.out.println(result.getString("username"));
    }

And true is not printing. Yet, if I remove the WHERE clause from the query, it will print out all of the usernames/id’s fine, and of course “TRUE”.

Am I missing something with Sqlite and it’s syntax?

edit: Just to clarify there is a user in the Users column with the id of 1 and with the username Fellixombc
edit: So I took your guy’s suggestion and tried prepare statement, heres my code now:

        PreparedStatement sqlStatement = this.sqlConnection.prepareStatement("SELECT * FROM Users WHERE username=?");
        sqlStatement.setString(1, "Fellixombc");
        ResultSet result = sqlStatement.executeQuery();
        int userId = 0;
        while(result.next()) {
            System.out.println("TRUE");
            userId = result.getInt("id");
            System.out.println(result.getString("username"));
        }
        result.close();

Answer 1

Essentially, you want to store the username, correct?

Your current query will retrieve all information on relative to a username. It’s what a SELECT query does, it retrieves.

If you need to create a new user, use:

INSERT INTO Users (username) Values ('Fellixombc');

I should tell you that you might need to provide more information in this query, depending on what other fields your Users table has.

EDIT:

In your select statement, you have an open single quote.

"SELECT * FROM Users WHERE username='Fellixombc"

should be

"SELECT * FROM Users WHERE username='Fellixombc'"

To avoid issues with SQL injection, consider the prepareStatement function.
