Answer / shwetha k
A cursor is a pointer to pointing to this memory area and used to retrieve data row by row instead of all row at a time.
select statement fetches only one row.so to overcome this problem cursor is used to hold the set of rows or data in one variable and can do whatever manipulation we want to do.
