Does a cursor in Android reference columns from 0 or 1?

Question

I am working with an SQLite Database and I am returning cursors successfully but I was wondering if a cursor references columns starting with 0 like arrays or just 1?

Answer 1

The Android documentation states that the getColumnIndex method from a SQLite Cursor returns the zero-based index for the given column name, or -1 if the column doesn't exist.

If you expect the column to exist use getColumnIndexOrThrow(String) instead, which will make the error more clear.

In short, they start at 0.
