SQL creating view with JOIN
View with JOIN
In this page, we are going to discuss, how two or more tables can be involved and join themselves to make a view in CREATE VIEW statement.
Example:
Sample table: orders
Sample table: customer
Sample table: agents
To create a view 'ordersview' by three tables 'orders', 'customer' and ' agents' with following conditions -
1. 'a' and 'b' and 'c' are the aliases of 'orders' and 'customer' and 'agents' table,
2. 'cust_code' of 'orders' and 'customer' table must be same,
3. 'agent_code' of 'orders' and 'agents' table must be same,
the following SQL statement can be used:
CREATE VIEW ordersview
AS SELECT ord_num, ord_amount, a.agent_code,
agent_name, cust_name
FROM orders a, customer b, agents c
WHERE a.cust_code=b.cust_code
AND a.agent_code=c.agent_code;
Output:
To execute query on this view
SELECT * FROM ordersview;

SQL: Tips of the Day
SQL Server SELECT into existing table.
INSERT INTO dbo.TABLETWO SELECT col1, col2 FROM dbo.TABLEONE WHERE col3 LIKE @search_key
This assumes there's only two columns in dbo.TABLETWO - you need to specify the columns otherwise:
INSERT INTO dbo.TABLETWO (col1, col2) SELECT col1, col2 FROM dbo.TABLEONE WHERE col3 LIKE @search_key
