[Muthukumar.GK]

Hi team,

When I am trying to implement belwo dynamic concept in postgreSql, getting
some error. Kindly find the below attached program and error. Please advise
me what is wrong here..

CREATE OR REPLACE PROCEDURE DynamicProc()

AS $$

DECLARE v_query TEXT;

C1 refcursor := 'result1';

begin



v_query := '';

v_query := ' OPEN C1 FOR SELECT * FROM public."Bankdetails"';



EXECUTE (v_query);

END;

$$

Language plpgsql;



 Calling procedure :-

--------------------------------

CALL DynamicProc();

FETCH ALL IN "result1";


Error :-

--------------



ERROR: syntax error at or near "OPEN"

LINE 1: OPEN C1 FOR SELECT * FROM public."Los_BankInfo" ^



QUERY: OPEN C1 FOR SELECT * FROM public."Los_BankInfo"

CONTEXT: PL/pgSQL function dynamicproc() line 9 at EXECUTE SQL state: 42601
