How can i writes these two ststements in DB2 Trigger

I declared v_SQLtableConValue,v_SqlString and added REFERENCING NEW AS n.

v_SQLtableConValue:='Monitered_'||:NEW.Process_Ste p_ID;

v_SqlString:='CREATE TABLE Monitered_' || :NEW.Process_Step_ID || ' (Batch_Name varchar2(20),Time_Stamp timestamp)';

SET v_SQLtableConValue = 'Monitered_' || n.Process_Step_ID;

SET v_SqlString = 'CREATE TABLE Monitered_' || n.Process_Step_ID || ' (Batch_Name varchar2(20),Time_Stamp timestamp)';

Statements supported in a trigger are:
CALL
FOR
full select
GET DIAGNOSTICS
IF
INSERT
ITERATE
LEAVE
MERGE
searched-delete
searched-update
SET Variable
SIGNAL
WHILE

bUT ITS SHOWING THE ERROR
DB2 SQL error: SQLCODE: -440, SQLSTATE: 42884, SQLERRMC: ||;FUNCTION

OK I GOT THE OUTPUT . wE NEED TO ADD CHAR(NEW.Process_Step_ID ) INSTEAD OF NEW.Process_Step_ID
