Hello,
I'm not very experienced in sapdb and java. I need explainaition why my code
hangs pc. Thanks in advance .
Three classes:
public class Database {
Connection connection;
public Database() {
try {
Class.forName("com.sap.dbtech.jdbc.DriverSapDB");//
} catch (ClassNotFoundException e) {};
try{
connection = java.sql.DriverManager.getConnection ("jdbc:sapdb://" +
"andriusxp" + "/" + "erp_dev",
"dba", "dba");
} catch (SQLException e){
System.out.println(e.getMessage());
};
}
public Connection getConnection() {
return connection;
}
}
public class TableA {
Connection con;
public void setConnection(Connection conn) {
con = conn;
}
public void update() {
try {
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("select * from erp_partners");
rs.next();
String hello = rs.getString(2);
rs.updateString(2, "AA"); // PROBLEM IS HERE
rs.updateRow();
System.out.println(hello);
}catch (SQLException e) {
System.out.println(e.getMessage());
}
}
}
public class Main {
public Main() {
Database db = new Database();
Connection conn = db.getConnection();
TableA a = new TableA();
a.setConnection(conn);
a.update();
System.out.println("End");
}
public static void main(String[] args) {
Main main = new Main();
}
}
