Couldn't read row 0, col -1 from CursorWindow

Question

I\'m trying to get records in my table. I\'m using this code

        if(c!=null){
            if(c.moveToFirst()) {

                String tipId = c.getString(c         


        

Answer 1

You should fix this to solve this error message

"Couldn't read row 0, col -1 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it."

it works in my code.

1. Try to position cursor by moveToFirst before reading data from it.

2. check for null. e,g; if (c != null && c.moveToFirst()) {}

3. check for count. e,g; (c != null && c.getCount() >0 && c.moveToFirst()){}

Answer 2

In your code

  c.getColumnIndex(DAO.TIP_ID)

is returning -1. This means value of DAO.TIP_ID doesnot match with any column name of table .Check if this value is correct and matches with a column name of the table you are accessing

add following line before the line which causes problem and post the Logcat output here

 Log.v("out-data",DAO.TIP_ID+" "+c.getColumnIndex(DAO.TIP_ID)+" "+c.getColumnName(0));

(add import statement import android.util.Log; in beginning of your code)

Answer 3

The query selection does not contain the column DAO.TIP_ID.
