CURSORS

Declare and OPEN a cursor:

DECLARE a cursor

  CURSOR cursor_name
     IS select_statement;

  CURSOR cursor_name
     [(parameter_name datatype, ...)]
        IS select_statement;

note: the "select_statement" cannot include an INTO clause.

Cursor parameters follow the syntax
   cursor_parameter [IN] datatype [{:= | DEFAULT} expr]

Cursor parameters are passed positionally when the cursor is opened, each parameter that was declared must have a corresponding parameter in the OPEN statement.

OPEN a cursor

  OPEN cursor_name;
or
  OPEN cursor_name param1 param2...;
