Invalid identifier on the Select statement

New to SQL. I'm having some trouble with a function.
Assignment is:
1. develop and execute a CREATE FUNCTION statement to create the DAY_ORD_SF function. Use the column DTCREATED table bb_basket as the date that the basket was created. Call the function TO_CHAR using the option of the DAY to extract the day of the week for a date value.
1. create a SELECT statement that lists the basket id and the day of the week set for each basket.
3. create a SELECT with a GROUP BY clause query to list the total number of baskets by day of the week. Who is the most popular of a day shopping? (Should discover that it is FRIDAY).

So far, I have the function:

CREATE OR REPLACE FUNCTION DAY_ORD_SF (P_ORDER_DATE IN BB_BASKET.DTORDERED%TYPE)
 RETURN VARCHAR2
 IS
   LV_DAY_WK VARCHAR2(3);
BEGIN
 SELECT TO_CHAR(P_ORDER_DATE, 'DAY') 
  INTO LV_DAY_WK
  FROM BB_BASKET
  WHERE P_ORDER_DATE = DTORDERED;
 RETURN LV_DAY_WK;
END;
/

Have you tried a select invalid identifier and get on o_dt. have you tried several different variables and impossible to find one that works.

SELECT DAY_ORD_SF(O_DT) "DAY", COUNT(*)
FROM BB_BASKET
GROUP BY DAY_ORD_SF(O_DT)
;

Any help would be appreciated.

>
DTCREATED is a column name in the table BB_BASKET. When I pass O_DT to DTCREATED, I get an error:
>
So track what causes this error. Your instructions were to use DTCREATED.

You use this query in your service

SELECT TO_CHAR(P_ORDER_DATE, 'DAY')
  INTO LV_DAY_WK
  FROM BB_BASKET
  WHERE P_ORDER_DATE = DTORDERED;

And the error tells you that LV_DAY_WK is too small. Why is it too small? Look at how it is defined and then look at the results of this query

SELECT TO_CHAR(DTCREATED, 'DAY')
  FROM BB_BASKET

and see if you can see what the problem is.

You do your development backward. Failed to start by trying to call a function that does not work. And you can't start by writing a function that includes queries that have not been tested.

The right way to generate code is to create simple components. Then test these simple components (for example a query) to ensure they work. Then mix the simple components in a component more complex as a function. Then, you can test the function of another request call.

The key is to start with simple things that work.

uniol all in the select statement

Yes you can put all THE UNION here

Select empname, 't' State, empno from tablename where column01 > 0

Union of all the

Select empname, 't' State, empno from tablename where column02 > 0

Union of all the

Select empname, condition of "W", empno FROM tablename WHERE COLUMN03 > 0

Union of all the

Select empname, condition of "Z", empno FROM tablename WHERE COLUMN04 > 0

and if you are looking for how to remove duplicates because your line might have satisfied all the conditions and my happen 4 times in your result set, you just need to give them an order and filter it.

For example, you want this

If column01 > 0 to condtion 't'

ELSE IF column02 > 0 that the condition of 'Y '.

Another condition of THAN > 0 IF COLUMN03 'w '.

otherwise if COLUMN04 > 0 that the condition of "Z".

There is no possibility of ambiguity in the SELECT clause because any identifier in the SELECT clause must be a database column name

Hello
Doc Oracle says the following on the identifiers in the SELECT in PL/SQL clause: there is no possibility of ambiguity in the SELECT clause because any identifier in the SELECT clause must be a database column name.
If we assume that only valid column identifier are allowed in the SELECT clause.
But I tried the following:
```
DECLARE
toto NUMBER := 10;
tata NUMBER := 0;
BEGIN
SELECT toto INTO tata FROM employees WHERE employee_id = 101;
DBMS_OUTPUT.PUT_LINE(tata);
END;
/
```
And there is no error telling me that toto is not a column in the employees table and the result is the same as: toto: = aunt;
Won't the doc or did I just miss something?
Thanks for your response!

...

You're right that toto is an identifier, but this isn't a column name. (Of a subquery) column alias are not database of the names of columns either, nor are the names of the user-defined function.

Also, there is a possibility for ambiguity even if all the names are the database column names.

Won't the doc or did I just miss something?

I can't say until I see the doc you're talking about.

Oracle documentation is sometimes misleading and sometimes just plain wrong. For each mistake outright example that I saw in the docs of Oracle, there might be 20 cases where the meaning is unclear or misleading and maybe 200 where I just read it wrong.

function() nested in the select statement

Oracle 11g. Try to nest a function within the select statement. Goal: get the average customer rating for each of the qualified user.
Select user_name, f_get_avg_cust_rating() "Notation.
of u, OTHER_TABLES o TAB_USER
where u.id = o.id and another condition matched;
How Oracle would deal with the sql. Is it
(1) first of all display records based on the where clause, then call the f_get_avg_cust_rating() for each of the selected records OR
(2) for the analysis in tables, the f_get_avg_cust_rating() will be called for each record met?

I tried to use a statement select count nested inside the original SELECT statement but without success.

Jeff
You should be able to use a CASE statement for this in collaboration with the County. COUNTY does not indicate that null instances no I have not specified a part to the CASE ELSE (so the default value is NULL).
```
COUNT(CASE ST.GENDER WHEN 'F' THEN 1 END) as Female_count,
COUNT(CASE ST.GENDER WHEN 'M' THEN 1 END) as Male_count, 
```
Note that you need to remove the Gender of your query column.

Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36')) < < < do not work.

Thank you for trying to help him. Thank you.
Select * from table (SplitFunction (select LOT_NO in the TRACER_SEARCH_SCHEDULE where JOB_ID = '36'))< do="" not="">

Try like this

Just make sure that your subquery returns only 1 row.
