SAP Hana Database Programming Interface-Jdbc__.net

Hana JDBC Driver

After installing the SAP HANA Client, the Ngdbc.jar of the installation directory is the JDBC database driver. Note the URL notation and Driver name: Driver:com.sap.db.jdbc.Driver url:jdbc:sap://ip_addr:30015 Port: 3 + instance number + code Example

Because there is no difference from other databases, here is a direct code. entity class

Package stone.hanatest;

public class Employeeentity {public
    String EmpId;
    Public String Gender;
    public int age;
    Public String EMail;
    Public String Phonenr;
    public String education;
    Public String Maritalstat;
    public int nrofchildren;
}
