Description

This message is used to indicate that a boolean cursor attribute is not supported in SnowScript or that there is no transformation that emulates its functionality in SnowScript. The following table shows the boolean cursor attributes that can be emulated:

Boolean Cursor Attribute	Status
%FOUND	Can be emulated
%NOTFOUND	Can be emulated
%ISOPEN	Not Supported

Example Code

Input Code:

CREATE OR REPLACE PROCEDURE cursor_attributes_proc
IS
    is_open_attr BOOLEAN;
    found_attr BOOLEAN;
    my_record table1%ROWTYPE;
    CURSOR my_cursor IS SELECT * FROM table1;
BEGIN
    OPEN my_cursor;
    LOOP
        FETCH my_cursor INTO my_record;
        EXIT WHEN my_cursor%NOTFOUND;
        is_open_attr := my_cursor%ISOPEN;
        found_attr := my_cursor%FOUND;
    END LOOP;
    CLOSE my_cursor;
END;
