Cross Join by Example in SQL Server

Cross join joins each row of one table with each row of another table. The result of the cross join is a Cartesian product (also called the cross product) of the two.


There are two syntaxes available for a cross join

You can also use the tables in from clause, without a where clause.

Cross Join

The best example of a cross product is a deck of cards. It contains 13 cards with rank from A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3 & 2. It contains a card suite of heart, diamond, club, and spade. The cartesian product of the above cards results in a 52 elements representing every card is a set.

The following queries create the sample database for our cross join. It contains two tables. cards & suites.
