Cannot fetch data from a table

[payal-garg]

I am trying to find records in a table where userId,password and host matches the one provided in EditText.Table name is Agency.But it shows FATAL EXCEPTION

HERE IS MY CODE

public class FTPLogin extends Activity {
EditText ftpUserName, ftpPassword, ftpHost;
String str_user, str_pass, str_host;
String whereClause;
Button ftpLogin;
BackendlessCollection<Map> result;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ftplogin);
    ftpUserName = (EditText) findViewById(R.id.ftp_identityField);
    ftpPassword = (EditText) findViewById(R.id.ftp_passwordField);
    ftpHost = (EditText) findViewById(R.id.ftp_host);
    ftpLogin=(Button)findViewById(R.id.ftp_loginButton);

    Backendless.setUrl( Defaults.SERVER_URL );
    Backendless.initApp( this, Defaults.APPLICATION_ID, Defaults.SECRET_KEY, Defaults.VERSION );

    ftpLogin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
 onFTPLogin();
}

});
}

public void onFTPLogin() {
    str_user = ftpUserName.getText().toString();
    str_pass = ftpPassword.getText().toString();
    str_host = ftpHost.getText().toString();
    //validate FTP login credentials
    whereClause = "userId="+str_user;
    whereClause+=" and ";
    whereClause+="password="+str_pass;
    whereClause+=" and";
    whereClause+=" host="+str_host;

    BackendlessDataQuery dataQuery = new BackendlessDataQuery();
    dataQuery.setWhereClause(whereClause);

// ***********************************************************
// Synchronous API:
// ***********************************************************
result = Backendless.Persistence.of(“Agency”).find(dataQuery);
Toast.makeText(FTPLogin.this, result.toString(), Toast.LENGTH_SHORT).show();

// ***********************************************************
// Asynchronous API:
// ***********************************************************
Backendless.Persistence.of(“Agency”).find(dataQuery,new AsyncCallback<BackendlessCollection<Map>>() {
@Override
public void handleResponse(BackendlessCollection<Map> response) {
// every loaded object from the “Contact” table is now an individual java.util.Map
Toast.makeText(FTPLogin.this,response.toString(),Toast.LENGTH_LONG).show();
//Intent i=new Intent(FTPLogin.this,SubmitActivity.class);
//startActivity(i);
}

        @Override
        public void handleFault(BackendlessFault fault) {
            // an error has occurred, the error code can be retrieved with fault.getCode()
            Toast.makeText(FTPLogin.this,"Login Failure",Toast.LENGTH_LONG).show();
        }
    });
}

}

Your “whereClause” is missing single quotes around string values. See the documentation for examples:
https://backendless.com/documentation/data/android/data_search_with_where_clause.htm

Test the where clause using console first:
https://backendless.com/feature-14-sql-based-search-for-data-objects-using-console/

Mark

[payal-garg]

but I am not trying to search hardcore values to be put inside single quotes.my values are strings coming from values inserted in edittext.pls tell me what should I do

[mark-piller]

the problem is you have syntax errors in the where clause.

[payal-garg]

so should I use StringBuilder?

[anton-govorushkin]

Hey Payal

Take a look, hope it will get things clear https://hastebin.com/anayewehiv.java
Also querying password field will not work, it’s a protected field.

Regards Anton

[payal-garg]

didnt work for me.I have attached the exception and i am gtting it on following lines

public void onClick(View v) {
onFTPLogin();
}
});
}

[payal-garg]

[payal-garg]

hey I have got rid of the crash which I was getting for using Synchronous and Asyncronous API together

But the response that is coming in from BackendlessCollection is not in reaadable format
I need to check if the query is satified and the record is found so that I can move to next activity.
But I am getting response as
com.backendless.BackendlessCollection@42013568
pls help me

here is my code

public void onFTPLogin() {
str_user = ftpUserName.getText().toString();
str_pass = ftpPassword.getText().toString();
str_host = ftpHost.getText().toString();
//validate FTP login credentials
whereClause = “userId=’”+str_user+"’";
whereClause+=" and “;
whereClause+=“password=’”+str_pass+”’";
whereClause+=" and";
whereClause+=" host=’"+str_host+"’";

    BackendlessDataQuery dataQuery = new BackendlessDataQuery();
    dataQuery.setWhereClause(whereClause);

// ***********************************************************
// Synchronous API:
// ***********************************************************
// result = Backendless.Persistence.of(“Agency”).find(dataQuery);
// Toast.makeText(FTPLogin.this, result.toString(), Toast.LENGTH_SHORT).show();

// ***********************************************************
// Asynchronous API:
// ***********************************************************
Backendless.Persistence.of(“Agency”).find(dataQuery,new AsyncCallback<BackendlessCollection<Map>>() {
@Override
public void handleResponse(BackendlessCollection<Map> response) {
int totalObj=response.getTotalObjects();
// every loaded object from the “Contact” table is now an individual java.util.Map
if(totalObj>1){
Log.d(“Backendless Success:”, response.getTableName());
Toast.makeText(FTPLogin.this,“Sucess”+ response.toString(), Toast.LENGTH_LONG).show();
//Intent i=new Intent(FTPLogin.this,SubmitActivity.class);
//startActivity(i);

            }
            else
            {
                Log.d("Backendless Fail:", response.toString());
                Toast.makeText(FTPLogin.this,"FAIL"+ response.toString(), Toast.LENGTH_LONG).show();
            }
        }

        @Override
        public void handleFault(BackendlessFault fault) {
            // an error has occurred, the error code can be retrieved with fault.getCode()
            Toast.makeText(FTPLogin.this,"Login Failure",Toast.LENGTH_LONG).show();
        }
    });
}

[mark-piller]

The response you’re getting, which is:

com.backendless.BackendlessCollection@42013568

is produced when you do something like this:

Log.i( FTPLogin.this, instanceOfBackendlessCollection );

This is totally expected if you decide to just “print” the collection object. Instead, you should get the data from the collection and do something useful with it…

Mark

[payal-garg]

well I didnt do that Mark.what I did was a toast to display response.toString().In my case response is the object name for BackendlessCollection.I just wanted to check if the data entered is getting matched with the records,if it does I can do further task.so how to check?

[sergey-chupov]

The .toString() method is not overriden in BackendlessCollection. Try printing the enclosed java List:

Log.i( FTPLogin.this, instanceOfBackendlessCollection.getCurrentPage() );
