you will get an error message
Select Customer.CustomerID from salesordertable Customer has not been defined in the subquery.
Are you sure? Check this
CREATE TABLE customer
(
customerid INT
)
CREATE TABLE salesorder
(
customerid INT
)
INSERTcustomer
SELECT1 UNION ALL
SELECT2
INSERTsalesorder
SELECT1
SELECT * FROM customer WHERE customer.customerid IN (SELECT customer.customerid FROM salesorder)
DROP TABLEcustomer
DROP TABLEsalesorder
The query will return all the rows from the customer table
