Question

I am getting the “Column count doesn’t match value count at row 1” but I couldn’t seem to fix it. I tried changing the quotation marks and data type but still no luck. Can anyone see where I’ve gone wrong?

public void actionPerformed(ActionEvent arg0) {
            if(!textField.getText().isEmpty() && !textField_1.getText().isEmpty() && !textField_2.getText().isEmpty() && !textField_3.getText().isEmpty() && !textField_4.getText().isEmpty() && !textField_5.getText().isEmpty() && !textField_6.getText().isEmpty() && !textField_7.getText().isEmpty())
            {
                String moduleName = textField.getText();
                String studId = textField_1.getText();
                String sFName = textField_2.getText();
                String sLName = textField_3.getText();
                int weekNo = Integer.parseInt(textField_4.getText());
                int lAttend = Integer.parseInt(textField_5.getText());
                int tAttend = Integer.parseInt(textField_6.getText());
                int wAttend = Integer.parseInt(textField_7.getText());

                lh.addStud(moduleName, studId, sFName, sLName , weekNo, lAttend, tAttend, wAttend);
            }
            else
            {
                lblNewLabel_4.setText("You have Missing Field");
            }
            fillDB();
           }
        });

Below is my query:

String aSQuery = "INSERT INTO Group6_Register VALUES ('" + moduleName + "', '" + studId + "', '" + sFName + "', '" +  sLName +"', '" +  weekNo + "', '" +  lAttend + "', '"  + tAttend + "', '" + wAttend + "')";
            statements = connection.prepareStatement(aSQuery);
            statements.executeUpdate();

“Column count doesn’t match value count at row 1”

usually occurs when your columns defined in the values clause don’t match your actual table columns.

say your table have 4 coulmns, col1 col2 col3 col4

now you want to only insert data into col2, col3, col4

your insert statement should be

Insert into table (col2, col3, col4) values(col2val, col3val, col3val)

However, i would strongly recommend you to use PreparedStatement while executing sql queries using JDBC.

   String query= "Insert into table (col2, col3, col4) Values(?,?,?)";
   Statement st = conn.preparedStatement(query);
   st.setString(1, col2value);
   st.setString(2, col3Val); 
   st.setString(3, col4Val);
