Hi ,

I am trying to access MSAccess database. Here is full code.

try {

QueryRunner run = new QueryRunner();
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") ;
Connection con1 = DriverManager.getConnection("jdbcdbc:studentData");
System.out.println("Connection ok.");
ResultSetHandler h = new BeanHandler(GetDataBean.class);
GetDataBean records = (GetDataBean) run.query(con1,"SELECT id, name, desc FROM tblStudent where id ='1234' ", h);
System.out.println("ID"+ records.getId());
System.out.println("Name"+records.getName());
System.out.println("Description"+ records.getDesc());
} catch (SQLException sqle) {
log.error("could not read a value", sqle);

} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}


Thanks

Do you have any idea how many classes there are called DBUtils? Should we just guess that you mean the Apache Commons DbUtils one?

Do you have methods setId, setName and setDesc that take Strings, or whatever the columns in your query are?

I already guessed that much. Can you now please answer my second question? Perhaps you can show us the GetDataBean class.

I am getting record when i use commons-dbutils1.0.jar .But when i am trying to use 1.3 version i am not getting any records. But i need to use 1.3 version.Because the below update function exists only in 1.3 version.

How can i do it? Could you please help me.

int inserts = run.update(con1,"INSERT INTO tblBachelor (id, name, desc) VALUES (?,?,?)", records.getId(), records.getName(), records.getDesc());





Bean Code :


public class GetDataBean

private String id;
private String name;
private String desc;

public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

Thanks
