today were going to talk about cross joins and when they should be used [Music] all right so the cross join is one of the more most seldom used joins thats because it creates whats called a cartesian product so lets see what that means i have a couple tables here so were going to select from a products table and were going to select from a division table and we run those together so the products table has three products soap toothbrush and shampoo and the divisions table has two divisions north and south if we want to bring every combination together of products and divisions we would use the cross join so lets write this out so we select from our products and then we cross join and were cross-joining with divisions now in every other join we always put an on clause in order to say what were joining on in the cross join we dont care the cross join should give us every combination of the two tables so lets run that and what we see here is basically on the division side we ha

In simple terms, a join relies on self-sufficient sets of data, i.e. sets should not depend on each other. On the other hand, CROSS APPLY is only based on one predefined set and can be used with another separately created set. A worked example should help with understanding this difference.
A cross join returns the Cartesian product of rows from the rowsets in the join. In other words, it will combine each row from the first rowset with each row from the second rowset. Note that this is potentially an expensive and dangerous operation since it can lead to a large data explosion.
A JOIN clause is used to combine rows from two or more tables, based on a related column between them. Notice that the "CustomerID" column in the "Orders" table refers to the "CustomerID" in the "Customers" table. The relationship between the two tables above is the "CustomerID" column.
A full outer join combines a left outer join and a right outer join. The result set returns rows from both tables where the conditions are met but returns null columns where there is no match. A cross join is a Cartesian product that does not require any condition to join tables.
CROSS JOIN adds records from both sides of the join, depending on the matching records designated in the ON clause (something like running a LEFT and RIGHT join simultaneously, if that helps). UNION/UNION ALL simply adds data vertically.
In SQL, CROSS JOINs are used to combine each row of one table with each row of another table, and return the Cartesian product of the sets of rows from the tables that are joined. When to use the CROSS JOIN? The CROSS JOIN query in SQL is used to generate all combinations of records in two tables.
A CROSS JOIN produces a cartesian product between the two tables, returning all possible combinations of all rows. It has no ON clause because you're just joining everything to everything. A FULL OUTER JOIN is a combination of a LEFT OUTER and RIGHT OUTER JOIN .
When to use the CROSS JOIN? The CROSS JOIN query in SQL is used to generate all combinations of records in two tables. For example, you have two columns: size and color, and you need a result set to display all the possible paired combinations of those—that's where the CROSS JOIN will come in handy.
The CROSS JOIN is used to generate a paired combination of each row of the first table with each row of the second table. This join type is also known as cartesian join. Suppose that we are sitting in a coffee shop and we decide to order breakfast.
What is Cross Join in SQL? The SQL CROSS JOIN produces a result set which is the number of rows in the first table multiplied by the number of rows in the second table if no WHERE clause is used along with CROSS JOIN. This kind of result is called as Cartesian Product.
