Writing string into table within procedure in DB2

I have the following snipplet:

SET retcode = SQLCODE;

IF(retcode='0')THEN
    SET SQLCMDINS = 'INSERT INTO RESULTTBL(SQLC, RET) VALUES ( '' '||SQLCMD||' '' , '||retcode||' )';
    PREPARE myStmt2 FROM SQLCMDINS; 
    EXECUTE myStmt2;
ELSE
    SET SQLCMDINS = 'INSERT INTO RESULTTBL(SQLC, RET) VALUES ("'|| SQLCMD ||'", '|| retcode ||')';
    PREPARE myStmt2 FROM SQLCMDINS; 
    EXECUTE myStmt2;
END IF;   

The problem is that SQLCMD is not written into the table. The retcode is working fine, but I get nothing for the string. The SQLCMD is the sql command that is being processed during that loop.

Any ideas on how to make this work?

Thanks in advance.
