Plsql block output to ODI variable

I have a plsql block which I am trying to execute in ODI stored procedure.

DECLARE
    v_time_cols       VARCHAR2(100) := 'DATA_REFRESH_TIME, UPDATE_DT';
     v_sql      VARCHAR2(1000);
    v_result   DATE;
    v_out varchar2(100);
BEGIN
    SELECT 'SELECT MAX(GREATEST(' ||
           LISTAGG('NVL(' || TRIM(REGEXP_SUBSTR(v_time_cols, '[^,]+', 1, LEVEL)) || 
                   ', TO_DATE(''1900-01-01'', ''YYYY-MM-DD''))', ', ')
           WITHIN GROUP (ORDER BY LEVEL) || 
           ')) FROM  MY_TABLE'
    INTO v_sql
    FROM dual
    CONNECT BY LEVEL <= REGEXP_COUNT(v_time_cols, ',') + 1;

    EXECUTE IMMEDIATE v_sql into v_out;
    DBMS_OUTPUT.PUT_LINE(v_out);

END;

Now, the output of v_out I wanted to store into another ODI variable. Is there any way to do that without involving any temp table in DB?
