Question

i have one constraint that need to be modify the cursor data. i cannot add the constraint in query.

How should I be update cursor ?

Answer 1

You cannot manually modify the contents of a Cursor obtained from a database query. You will need to read the data out of the Cursor, modify it per your "constraint", and then put the results in a MatrixCursor or an ArrayList of model objects or something.
