SQL driving me mental, please help

Question

I have the following tables in my database.
customerinfo
lineitem
orderhistory
productinfo
I just recently changed my database to provide for normalisation but it screwed with my sql statement.
I used to be able to type:
ResultSet res = stmt.executeQuery("SELECT * FROM orderhistory WHERE CustomerDescription ='"+CID+"' ORDER BY OrderID");
This would return a:
ProductDescription
Quantity
Cost
and Total Cost.
These were originally all in a single table but now ProductDescription is in productinfo, Cost is in productinfo, Quantity is in Lineitem, and TotalCost is in orderhistory.
Can anyone figure out the statement i must use to get the correct result set???? Please, I have tried everything and have hit a brick wall everytime.

Answer 1

Sorry to bother you again but this is driving me insane and I really need to get this sorted. Here is the problem.
I have three table in my database as follows:
LineItem Table consists of 3 fields:
LineItemId, OrderID and Quantity.
OrderHistory table has 3 fields:
OrderID, CustomerID and Total
ProductInfo table has 4 fields:
ProductID, ProductDescription, Cost & ProductLocation.
OrderID is the primary key:
What I want to do is extract the OrderId, ProductDescription, Quantity, ProductCost & Total where CustomerID = '.....'
I am having major problems with linking my tables and receiving duplicate results.
At the Java side of things, i would select a customerID, and the above order details would be returned. Here is the code i am using:
ResultSet res = stmt.executeQuery("select * from orderhistory o, customerinfo p, productinfo c where o.CustomerID = p.CustomerID");
while(res.next())
txtCustomerID.setText(res.getString("CustomerID"));
txtArea.append("ORDER ID: " + res.getString("OrderID")+ "\n" );
txtArea.append("**************************************************" + "\n");
txtArea.append("Product Description: " + res.getString("ProductDescription" )+"\n");
//txtArea.append("Product Quantity: " + res.getString("Quantity")+"\n" );
txtArea.append("Product Indidvidual Cost: " + res.getString("ProductCost")+"\n" );
txtArea.append("Product Total Cost: " + res.getString("Total")+"\n" );
txtArea.append("**************************************************" + "\n");
Any help would be greatly appreciated.
