0 IBM Data Studio & Cursor

I am trying to use IBM data studio 3.1.1 to create the cursor but keep getting error.

The code is very simple .

CREATE TABLE T6 ( C1 INT, C2 CHAR(20));

INSERT INTO T6

  VALUES (1, 'A');

INSERT INTO T6

  VALUES (2, 'B');

INSERT INTO T6

  VALUES (3, 'C');

INSERT INTO T6

  VALUES (4, 'D');

INSERT INTO T6

  VALUES (5, 'E');

DECLARE CU1 CURSOR WITH HOLD FOR SELECT * FROM T6;

OPEN CU1;

FETCH CU1;

FETCH CU1;

FETCH CU1;

COMMIT;

FETCH CU1;

CLOSE CU1;

However, when  I declare the cursor , I will get the error

An unexpected token "DECLARE CU1 CURSOR WITH HOLD FOR SELECT * F" was found following "BEGIN-OF-STATEMENT".  Expected tokens may include:  "<space>".. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.13.111

I can confirm the SQL terminate is set up properly.

The same code works fine form db2cmd.

I still can not find out why it does not work in Data studio
