Updating records using update statements with join in SQL Server
You can update records using update statements with join in SQL Server by using the
UPDATE statement with the JOIN clause. The JOIN clause allows you to join two tables together and update the records in one table based on the records in the other table.
The syntax for updating records using update statements with join in SQL Server is as follows:
SQL
UPDATE table_name
SET column1 = value1,
    column2 = value2,
    ...
FROM table1
JOIN table2
ON table1.column1 = table2.column1;
The table_name is the name of the table that you want to update. The
column1, column2, etc. are the columns that you want to update. The
value1, value2, etc. are the new values for the columns. The
table1 and table2 are the names of the tables that you want to join. The
column1 and column2 are the columns that you want to join on.
For example, the following code will update the CustomerName column in the
Customers table to John Smith for all customers where the
CustomerID is 100:
SQL
UPDATE Customers
SET CustomerName = 'John Smith'
FROM Customers
JOIN Orders
ON Customers.CustomerID = Orders.CustomerID
WHERE Customers.CustomerID = 100;
This code will first join the Customers and Orders tables on the
CustomerID column. Then, it will update the CustomerName column in the
Customers table to John Smith for all rows where the 
CustomerID is 100.
