In the table named "ProductDeliveryTBL" , Column ProductID is the Foreign Key.
In the table named "Product" table, Column ProductID is the Primary Key.
The data about ProductDesc and ProductPrice is not available in "ProductDeliveryTBL" table. It is available in the "Product" table.
To get the Product Delivery data along with ProductDesc and ProductPrice using the SQL, we have to use the column "ProductID",
which is a common column in both the tables. Need to use this column "ProductID" to do Inner Join between the tables
"ProductDeliveryTBL" and "Product".
The following SQL query acheives the above said task.
Text Editor below has the SQL Query, click the "View Result" button, to see the result.
Select ProductDeliveryTBL.CustomerName, ProductDeliveryTBL.ProductID, Product.ProductDesc, Product.ProductPrice, ProductDeliveryTBL.DeliveryStatus
From ProductDeliveryTBL
Inner Join Product on Product.ProductID = ProductDeliveryTBL.ProductID
Note: For every ProductID in the ProductDeliveryTBL, the correct ProductDesc and ProductPrice is retrieved.
