Unable to get AutoGenerated ID in MySql JDBC


I am trying to get an autogenerated Id after performing an insert operation. I have a table called sg_InsuranceInfo, and it generates an autoIncremented id. So I need to get it. I have attached sample code for reference

try
{
    String insertQuery = "INSERT INTO sg_InsuranceInfo(Patient_Name,LIC_Name) VALUES(?,?)";
    PreparedStatement preparedStatement = getConnectionObject().getConnection().prepareStatement(insertQuery,  Statement.RETURN_GENERATED_KEYS);
    preparedStatement.setString(1, insuranceInformation.getPatientName());
    preparedStatement.setString(2, insuranceInformation.getLicName());
    int noOfRowsAffected = preparedStatement.executeUpdate();
    if (noOfRowsAffected != 0)
    {
        ResultSet resultSet = preparedStatement.getGeneratedKeys();
        if(resultSet.next())
        {
            System.out.println(resultSet.getInt(1));
        }
    }
}
catch (SQLException e)
{
    e.printStackTrace();
} 

This is the error text

Solution

  • It does the job

    public void saveInformation(InsuranceInformation insuranceInformation)
    {       
        try
        {
            int noOfRowsAffected = getConnectionObject().getStatement().executeUpdate(
                    "INSERT INTO sg_InsuranceInfo(Patient_Name,LIC_Name) VALUES(" + "'" + insuranceInformation.getPatientName() + "','" + insuranceInformation.getLicName() + "'"
                            + ")");
            if (noOfRowsAffected != 0)
            {
                ResultSet autoGeneratedId = getConnectionObject().getStatement().executeQuery("SELECT SCOPE_IDENTITY()");
                if(autoGeneratedId.next())
                {
                    System.out.println(autoGeneratedId.getInt(1));
                }
            }
        }
        catch (SQLException e)
        {
            e.printStackTrace();
        }
    }
