Error-local collection types not allowed in SQL statements

Question

TYPE WEEK_NUM_T  IS VARRAY(10) OF VARCHAR2(10);
vc_weeknum WEEK_NUM_T;
SELECT DISTINCT to_char(y.week_number_in_year) BULK COLLECT INTO vc_weeknum
    FROM DD_TMP x, TIME y
    WHERE x.DATE_TM = y.ORACLE_DATE;
INSERT INTO TMP_HOLD
    (SELECT *
         FROM TMP
         WHERE DATE_TM IN (SELECT * FROM TABLE(vc_weeknum));It seems like the TABLE() function don't work. What is the workaround?

Answer 1

You haven't provided enough of your code to tell, but you are probably trying to use a pl/sql type instead of a sql type. Please see the reproduction of error, then correction below.
