On Oracle, how can I list ALL tables and ALL materialized views without indexes using a SELECT command ?

Well, normally I wouldn't do this, but here you go:
SELECT t.TABLE_NAME
FROM USER_TABLES t
LEFT OUTER JOIN (SELECT DISTINCT TABLE_NAME
FROM USER_INDEXES) i
ON i.TABLE_NAME = t.TABLE_NAME
WHERE i.TABLE_NAME IS NULL;
Perhaps your question should be "Why did someone just do my homework for me?".
Best of luck.

I am wondering whether I can create a column with dollar sign? The output should look like the area marked by red line. But the column can still be calculated like number.
I am not sure whether it is capable.
You can try this:
select to_char(500, '$999') from dual
Column-Name with Dollar:
CREATE TABLE t1 (ID int, "$Sal" int);
INSERT INTO t1 values(1,100);
SELECT id, "$Sal" * 10 FROM t1;

DECLARE
CURSOR c_CUR IS
SELECT id, table_name, is_deleted FROM truncate_table WHERE IS_DELETED=1
ORDER BY id DESC;
BEGIN
FOR C IN c_CUR LOOP
EXECUTE IMMEDIATE 'TRUNCATE TABLE'|| C.table_name;
END LOOP;
END;
I HAVE AN ERROR TABLE OR CLUSTER KEYWORD IS MISSING
It is very clear that you are not creating a dynamic query properly. Space is missing between TABLE'|| C.table_name
It must be something like this:
EXECUTE IMMEDIATE 'TRUNCATE TABLE '|| C.table_name; -- see space after TABLE

I have two tables
TABLE1
-DATADATE
-ISIN
-INDEXNAME
TABLE2
-AS_OF_DATE
-ISSUER_ISIN
-GPSCORE
-SPSCORE
I would like to merge the two tables by matching on:
AS_OF_DATE = DATADATE
and
ISIN = ISSUER_ISIN
Try this one:
SELECT * FROM TABLE1 tb1
INNER JOIN TABLE2 tb2
ON tb1.DATADATE = tb2.AS_OF_DATE
AND tb1.ISIN = tb2.ISSUER_ISIN

I have an existing table. I have a select query which might return multiple rows. I want to display all rows that this select query returns, without using cursor. How can I achieve it in pl sql?
If I understand your question correctly, the following is a possible solution:
BEGIN
FOR T IN (SELECT 'data_1' col_1,
'data_2' col_2,
'data_3' col_3
FROM dual) LOOP
dbms_output.put_line('Query returns: '||T.col_1||', '||T.col_2||', '||T.col_3);
END LOOP;
END;

I have something like this :
Select id , name from table1 (how to orderby alphabetical from the name(column))
the result from select should be :
1.Alex
2.Bob
3.Charlie
Use this:-
Select id , name from table1 ORDER BY NAME
By default, the order is ascending. If you want to get the names in the descending order use:-
ORDER BY NAME DESC
