So I have a function to return an Average of a column such as
CREATE OR REPLACE FUNCTION avgCol
RETURN DEC IS avgNum DEC;
BEGIN
SELECT AVG(myCol)
INTO avgNum
FROM MyTable;
RETURN avgNum;
END;
/
While trying to test the results, i have the following
SELECT avgCol
INTO RESULT
FROM DUAL;
but it gives me the error
ORA-00905: missing keyword
00905. 00000 - "missing keyword"
*Cause:
*Action:
Error at Line: 175 Column: 6
Where line 175 is INTO RESULT. As far as I know, this is a scalar function and I'm trying to return a signal variable so it should work right? What keyword am I missing here? Also I know I can just use AVG(), but I am learning how to create a scalar function. this is strictly for learning purposes.
While testing your code (which should be ok), you need
SELECT avgCol AS result FROM DUAL;
