![]() If you want to find artists who don’t have any albums, you can add a WHERE clause as shown in the following query: SELECT Name, ORDER BY Name Code language: SQL (Structured Query Language) ( sql ) Similar to the INNER JOIN clause, you can use the USING syntax for the join condition as follows: SELECT Name, If a row from the left table doesn’t have a matching row in the right table, SQLite includes columns of the rows in the left table and NULL for the columns of the right table. The left join returns all rows from the artists table (or left table) and the matching rows from the albums table (or right table). The LEFT JOIN clause selects data starting from the left table ( artists) and matching rows in the right table ( albums) based on the join condition ( artists.ArtistId = albums.ArtistId). This statement selects the artist names and album titles from the artists and albums tables using the LEFT JOIN clause: SELECT Name, The clause USING(ArtistId) is equipvalent to the clause ON artists.ArtistId = albums.ArtistId. INNER JOIN artists USING(ArtistId) Code language: SQL (Structured Query Language) ( sql ) In case the column names of joined tables are the same e.g., ArtistId, you can use the USING syntax as follows: SELECT This query uses table aliases ( l for the albums table and r for artists table) to shorten the query: SELECT If the join condition evaluates to true (or 1), the columns of rows from both albums and artists tables are included in the result set. In this example, the INNER JOIN clause matches each row from the albums table with every row from the artists table based on the join condition ( artists.ArtistId = albums.ArtistId) specified after the ON keyword. The following statement returns the album titles and their artist names: SELECTĬode language: SQL (Structured Query Language) ( sql ) Note that SQLite doesn’t directly support the RIGHT JOIN and FULL OUTER JOIN. Each join clause determines how SQLite uses data from one table to match with rows in another table. To query data from both artists and albums tables, you use can use an INNER JOIN, LEFT JOIN, or CROSS JOIN clause. Summary: in this tutorial, you will learn about various kinds of SQLite joins to query data from two or more tables.įor the demonstration, we will use the artists and albums tables from the sample database.Īn artist can have zero or many albums while an album belongs to one artist.
