For query:

how many tables can sql server join

Our model ranks this at top 1:

id: 7485889
contents: How many tables can I have in 1 Sql Azure Database. I know in Sql Server, Tables per database Limited by number of objects in a database, Database objects include objects such as tables, views, stored procedures, user-defined functions, triggers, rules, defaults, and constraints. The sum of the number of objects in a database cannot exceed 2,147,483,647..

The actual relevant document is (we rank this at 949, BM25 rank this at 300):

id: 7485894
contents: SQL JOIN. A JOIN clause is used to combine rows from two or more tables, based on a related column between them. Let's look at a selection from the Orders table: Then, look at a selection from the Customers table: 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. Then, we can create the following SQL statement (that contains an INNER JOIN), that selects records that have matching values in both tables: Example SELECT Orders.OrderID, Customers.CustomerName, Orders.OrderDate

For query:

Our model ranks this at top 1:

id: 6680536
contents: A baby in general. Dreams that include babies are positive signs. Dreaming about interacting with a baby or simply seeing a baby in a dream can mean that pleasant surprises and fortuitous occurrences are about to occur in your life. This dream doesn't specify what, but something unexpectedly good is on your horizon.

The actual relevant document is (we rank this at 2, BM25 rank this at 993):

id: 7551052
