Description
This EWI is added when Cursors other than Local Cursors are identified. Currently, Snowflake Scripting only supports Local Cursors. Thus, all Cursors are translated as Local Cursors.
Code Example
Input Code:
CREATE OR ALTER PROCEDURE globalCursorTest
AS
BEGIN
-- Should be marked with MSCEWI4036
DECLARE MyCursor CURSOR GLOBAL STATIC READ_ONLY
FOR
SELECT *
FROM exampleTable;
-- Should not be marked
DECLARE MyCursor2 CURSOR LOCAL STATIC READ_ONLY
FOR
SELECT testCol
FROM myTable;
RETURN 'DONE';
END;
Output Code:
CREATE OR REPLACE PROCEDURE PUBLIC.globalCursorTest ()
RETURNS VARCHAR
LANGUAGE SQL
EXECUTE AS CALLER
AS
$$
DECLARE
-- Should be marked with MSCEWI4036
/*** MSC-ERROR - MSCEWI4036 - SNOWFLAKE SCRIPTING ONLY SUPPORTS LOCAL CURSORS ***/
MyCursor CURSOR
FOR
SELECT
*
FROM
PUBLIC.exampleTable;
-- Should not be marked
MyCursor2 CURSOR
FOR
SELECT
testCol
FROM
PUBLIC.myTable;
BEGIN
RETURN 'DONE';
END;
$$;
