1  –  cursor-name

    The name of the cursor you want to declare. Use a name that is
    unique among all the cursor names in the module. Use any valid
    SQL name. See  the User_Supplied_Names HELP topic for more
    information on identifiers.

2  –  FOR statement name

    A name that identifies a prepared SELECT statement that is
    generated at run time.

3  –  INSERT_ONLY

    Specifies that a new list or a new row is created or opened.

4  –  LIST_CURSOR

    Specifies that you are declaring a cursor to access the elements
    in a list.

5  –  preserve-clause

    Syntax options:

       PRESERVE ON COMMIT
       PRESERVE ON ROLLBACK
       PRESERVE ALL
       PRESERVE NONE

    Specifies when a cursor remains open.

    o  PRESERVE ON COMMIT

       On commit, all cursors close except those defined with the
       WITH HOLD PRESERVE ON COMMIT syntax. On rollback, all cursors
       close including those defined with the WITH HOLD PRESERVE ON
       COMMIT syntax.

       This is the same as specifying the WITH HOLD clause without
       any preserve options.

    o  PRESERVE ON ROLLBACK

       On rollback, all cursors close except those defined with the
       WITH HOLD PRESERVE ON ROLLBACK syntax. On commit, all cursors
       close including those defined with the WITH HOLD PRESERVE ON
       ROLLBACK syntax.

    o  PRESERVE ALL

       All cursors remain open after commit or rollback. Cursors
       close with the CLOSE statement or when the session ends.

    o  PRESERVE NONE

       All cursors close after a CLOSE, COMMIT, or ROLLBACK
       statement, when the program stops, or when you exit from
       interactive SQL.

       This is the same as not specifying the WITH HOLD clause at
       all.

6  –  READ_ONLY

    Specifies that the cursor is not used to update the database.

7  –  SCROLL

    Specifies that Oracle Rdb can read the items in a list from
    either direction (up or down) or at random.

8  –  TABLE_CURSOR

    Specifies that you are declaring a cursor to access the rows in a
    table.

9  –  UPDATE_ONLY

    Specifies that the cursor is used to update the database.

10  –  WITH_HOLD

    Indicates that the cursor remain open and maintain its position
    after the transaction ends. This is called a holdable cursor.
