SQL INNER JOIN Keyword


SQL INNER JOIN Keyword

The INNER JOIN watchword chooses all lines from the two tables insofar as there is a match between the segments in both tables.

SQL INNER JOIN Syntax

SELECT column_name(s)
FROM table1
Inward JOIN table2
ON table1.column_name=table2.column_name;

or:

SELECT column_name(s)
FROM table1
JOIN table2
ON table1.column_name=table2.column_name;

PS! INNER JOIN is equivalent to JOIN.

SQL INNER JOIN

Database

In this instructional exercise we will utilize the outstanding database.

Below is a determination from the "Clients" table:

CustomerID PersonName Username password email
1

2 Jeff L. Robinson Horks1963 boh6taBio JeffLRobinson@rhyta.com
3 Donna M. Montgomery Stareer oopei7hoSah DonnaMMontgomery@jourrapide.com

And a determination from the "Requests" table:

OrderID CustomerID EmployeeID OrderDate ShipperID
10308 2 7 2001-10-05 3
10309 37 3 1999-12-05 1
10310 77 8 1989-12-15 2

SQL INNER JOIN Example

The following SQL explanation will restore all clients with orders:

Example

SELECT Customers.CustomerName, Orders.OrderID
FROM Customers
INNER JOIN Orders
ON Customers.CustomerID=Orders.CustomerID
ORDER BY Customers.CustomerName;

Note: The INNER JOIN watchword chooses all lines from both tables insofar as there is a match between the sections. On the off chance that there are pushes in the "Clients" table that don't have coordinates in "Requests", these clients won't be listed.
