Sqlite - One-To-Many Relationship SELECT Query

Question

Prequisites

There are two tables in my file (it's about vinyl records):

Records

ID	Title
1	Title_1
2	Title_2

Styles

ID	recordId	style
1	1	Blues
2	1	Disco
3	2	Blues
4	2	Electro

(Styles.style is stored as an Integer but a String is used for simplicity here)

Following condition is set for table Styles:
Styles.recordId = Records.ID for every given vinyl record

->This is necessary to find all styles related to one specific vinyl record

Therefore, there are two vinyls stored:

Title_1 has two styles Blues, Disco
Title_2 has two styles Blues, Electro

Question

In my SELECT query, I want to find vinyl records with a certain style

Find Titles with one style

If I want to find a vinyl record with one specific style, it seems pretty straight forward.
I use:

SELECT Records.Title
FROM Records
JOIN Styles ON Styles.recordId = Records.ID
WHERE Styles.style=Disco

With the desired result:

(Title_1)

Find Titles with more styles

Let`s say, I want to find all titles with the styles (Blues AND Electro)
Using the statement from before and just adding another statement does not seem to work:

SELECT Records.Title
FROM Records
JOIN Styles ON Styles.recordId = Records.ID
WHERE Styles.style=Blues AND Styles.style=Electro

This does not work as the column Styles.style never consists of both styles at the same time.

How can I tell SQLite to return all titles that satisfy the requirement? The output should be

(Title_2)

EDIT: Fixed tables not rendering

Answer 1

For this you need to filter the rows of your resultset for the styles that you want and aggregation with the condition in the HAVING clause that for a title both styles exist:

SELECT r.id, r.Title
FROM Records r JOIN Styles s 
ON s.recordId = r.ID
WHERE s.style IN ('Blues', 'Electro')
GROUP BY r.id, r.Title
HAVING COUNT(*) = 2;

I assume that in the table style the combination of the columns recordId and style is unique.
