asked on

sql to add additional rows

Here is some sample data from the order and customer tables (SQL Server 2014)

Order Table
OrderID  OrderAmount    
1              300    
2              400          


Customer Table
CustomerID  CustomerFirstName CustomerLastName
500                Fred                          Smith

Need to write a query that will return all rows from customer table with a row for each order that exists

Given sample data would like query to return the following

CustomerID  CustomerFirstName CustomerLastName OrderID  OrderAmount
500                Fred                          Smith                        1             300
500                Fred                          Smith                        2             400

Not sure of best way to do this

try:

select c.*, o.*
from Customer c, Order o

Open in new window

But you really want to know what you want to return, and if this is the expected result

>>from Customer c, Order o

That will work but probably better to use the new ANSI join syntax.
Hi,
Try
select a.*,b.*
from customertable,ordertable

Open in new window

I think better to have/add customerID column (as one foreign key) in Ordertable, to know which customer does make which order.


@Peter,

Please review previous Experts comments.  That has already been posted.

and yours is incorrect.  You cannot select a.* if you don't alias the tables.
