sql developer how to filter date - sql

Question

Peace
I have a table full of values and I need to filter all the dates of each month 10
That is to delete everyone who is between 10-01-2022 TO 10-31-2022
And not a specific date as I presented
create table content(
cname varchar2(1),
type varchar2(15),
episodes number,
country varchar2(15),
language varchar2(15),
releasedate date,
primary key(cname, type));
insert into content values('A','film', 1, 'China', 'Mandarin', '03/10/2022');
insert into content values('B','film', 1, 'Taiwan', 'Cantonese', '30/10/2022');
insert into content values('C','film', 1, 'Singapore', 'Malay', '15/09/2022');
insert into content values('A','series', 8, 'Korea', 'Korean', '28/09/2022');
insert into content values('B','series', 10, 'China', 'Mandarin', '03/10/2022');
insert into content values('C','series', 18, 'Korea', 'Korean', '01/11/2022');
insert into content values('D','series', 8, 'Korea', 'Korean', '16/09/2022');
insert into content values('D','documentary', 3, 'China', 'Mandarin', '18/10/2022');
insert into content values('E','documentary', 6, 'Taiwan', 'Mandarin', '17/10/2022');
SELECT cname,type,country,episodes,language,releasedate
FROM content
minus
SELECT cname,type,country,episodes,language,releasedate
FROM content
WHERE content.country ='China'
AND
content.TYPE ='documentary'
AND
content.MONTH(releasedate) =10;

Answer 1

If is intended to fetch all data of October without checking the year, we can use EXTRACT, see here the documentation
SELECT cname, type, country, episodes, language, releasedate
FROM content
WHERE EXTRACT(MONTH FROM releasedate) = 10;
Otherwise, if only the October 2022 should be considered, we will prefer to use BETWEEN rather than two times EXTRACT for both year and month.
SELECT cname, type, country, episodes, language, releasedate
FROM content
WHERE releasedate BETWEEN
TO_DATE('2022-10-01','YYYY-MM-DD') AND
TO_DATE('2022-10-31','YYYY-MM-DD');
If your dates can contain a time, we should add a TRUNC to avoid a date like '10/31/2022 12:22:22' will not be found:
SELECT cname, type, country, episodes, language, releasedate
FROM content
WHERE TRUNC(releasedate) BETWEEN
TO_DATE('2022-10-01','YYYY-MM-DD') AND
TO_DATE('2022-10-31','YYYY-MM-DD');
Here we can verify this is working correctly: db<>fiddle

Change from:
SELECT ...
MINUS
SELECT ... WHERE X AND Y AND Z
to a single query:
SELECT ...
WHERE NOT X OR NOT Y OR NOT Z
Which for your query would be:
SELECT *
FROM content
WHERE country != 'China'
OR type != 'documentary'
OR releasedate < DATE '2022-10-01'
OR releasedate >= DATE '2022-11-01';
or, if you can have NULL values:
SELECT *
FROM content
WHERE country != 'China'
OR country IS NULL
OR type != 'documentary'
OR type IS NULL
OR releasedate < DATE '2022-10-01'
OR releasedate >= DATE '2022-11-01'
OR releasedate IS NULL;
If you want to always exclude that month then use a mix of AND and OR:
SELECT *
FROM content
WHERE ( country != 'China'
OR type != 'documentary' )
AND ( releasedate < DATE '2022-10-01'
OR releasedate >= DATE '2022-11-01' );
