How do I add a new row of data into my Derby database?

Question

Using Netbeans, I have my database and table set up, and have added my data manually, in which I am able to see within my application I am building, as intended.

I would like the user to add their own data in which will be appended to a new row on the table. However, I am having trouble trying to write code in order to do this.

        Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();
        Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/stockApplication");
        Statement stat = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);

        String insertDerbyData = "INSERT INTO TIGER_INFO" 
                    + "(TIGER_ID, TIGER_LOCATION)"
                    + "VALUES (123456, Store)";
        stat.executeUpdate(insertDerbyData);

I cannot execute the above code as I'm returned with an error mentioning that 'STORE' is not in any table. 'STORE' is meant to be a value for my 'TIGER_LOCATION' column. What's going on here?

In theory, I have two columns, and I would like to add both values, '123456' and 'Store' into their respective columns. How do I go about correctly doing so?

Answer 1

如果TIGER_LOCATION是字符串/ varchar列，而Store是字符串文字，则该值必须用单引号引起来，就像在大多数基于SQL的数据库中一样：

INSERT INTO TIGER_INFO (TIGER_ID, TIGER_LOCATION) VALUES (123456, 'Store')

Answer 2

Strings should be between '...' you have to use :

VALUES (123456, 'Store')
