Additionally, a cursor may be INSENSITIVE, in which case the DBMS tries to apply sensitivity as much as possible.

In computer science, a database cursor is a control structure that enables traversal over the records in a database.

Cursors facilitate subsequent processing in conjunction with the traversal, such as retrieval, addition and removal of database records.The SQL:2003 standard defines positioned update and positioned delete SQL statements for that purpose.Such statements do not use a regular WHERE clause with predicates. The cursor must be opened and already positioned on a row by means of The cursor must operate on an updatable result set in order to successfully execute a positioned update or delete statement.A cursor can be viewed as a pointer to one row in a set of rows.The cursor can only reference one row at a time, but can move to other rows of the result set as needed.A holdable cursor is kept open over COMMIT and closed upon ROLLBACK.
