![]() column names Change that to: SELECT title, filepath FROM books INNER JOIN theme ON books.bookID theme.bookID WHERE bookID And I think you will be fine. Inner join returns the rows that match in both tables Left join returns all rows from the left table Right join returns all rows from the right table Full join returns whole rows from both tables If you lack knowledge about the SQL join concept in the SQL Server, you can see the SQL Join types overview and tutorial article. How do you perform a cross join in SQLite A cross join, also known as a Cartesian join, in SQLite combines every row from the first table with every row from the second table. 1 Answer Sorted by: 2 There is no space (' ') between JOIN and table 1 name. And in the albums table, the AlbumId is the primary key. Heres an example of an inner join: SELECT column1, column2 FROM table1 INNER JOIN table2 ON table1. In the tracks table, the AlbumId column is a foreign key. Used by: select-core select-stmt table-or-subquery update-stmt update-stmt-limited. The tracks table links to the albums table via AlbumId column. The following illustrates the syntax of the inner join clause:SELECT a1, a2, b1, b2 FROM A INNER JOIN B on B.f A.f Code language: SQL (Structured Query. INNER JOIN (OR JOIN) Gives the records that have common attributes in both tables. table-or-subquery join-operator table-or-subquery join-constraint. ![]() Let’s take a look at the tracks and albums tables in the sample database. The following diagram illustrates the INNER JOIN clause: SQLite INNER JOIN examples Only the rows in the A table: (a1,1), (a3,3) have the corresponding rows in the B table (b1,1), (b2,3) are included in the result set. This logic is applied if you join more than 2 tables. In other words, the INNER JOIN clause returns rows from the A table that has the corresponding row in B table. SQLite does not support Right Outer Joins or Full Outer Joins so in this article I am going to get into how to get around that as well as deep dive into all joins in. This tutorial explains INNER JOIN and uses in SQLite. JOIN, CROSS JOIN, and INNER JOIN are syntactic equivalents. ![]() The following illustrates the syntax of the inner join clause: SELECT a1, a2, b1, b2 FROM A INNER JOIN B on B.f A. The A table links to the B table using a foreign key column named f. If the value of the f column in the A table equals the value of the f column in the B table, it combines data from a1, a2, b1, b2, columns and includes this row in the result set. SQLite INNER JOIN: In SQLite the INNER JOIN selects all rows from both participating tables to appear in the result if and only if both tables meet the conditions specified in the ON clause. The INNER JOIN clause combines columns from correlated tables. For each row in the A table, the INNER JOIN clause compares the value of the f column with the value of the f column in the B table. ![]()
