Error while exceuting a SAP HANA Procedure

Hi HANA Gurus,

I am new to HANA SQL Scripting and I have created the following procedure

CREATEPROCEDURE"RAJ_HANA"."CURSOR_FOR_LOOP"LANGUAGE SQLSCRIPT

AS

VAR_EMNO INTEGER;   

CURSOR EMP FORSELECT EMPNO FROM"RAJ_HANA"."EMP";

BEGIN 

FOR EMP_CUR AS EMP DO

FETCH EMP INTO VAR_EMNO;

INSERTINTO"RAJ_HANA"."EMP_1"VALUES(:VAR_EMNO) ;

SELECT * FROM"RAJ_HANA"."EMP_1";

END FOR;

END;

Error:

Could not execute 'Call "RAJ_HANA"."CURSOR_FOR_LOOP"' in 41 ms 684 µs .

SAP DBTech JDBC: [150]: statement cancelled or snapshot timestamp already invalidated: [150] "RAJ_HANA"."CURSOR_FOR_LOOP": line 8 col 1 (at pos 147): [150] (range 3): statement cancelled or snapshot timestamp already invalidated
