无论以前的代码如何，如何按状态排序？

Question

“请提供我们用于任何类型设计工作的供应商列表，并显示与它们处于相同状态的所有其他供应商。”

我试图过滤它，即使类别不正确，CA州的每个人都应该出现在这里。应该有75个，但我仍然只有3个。我使用的是我认为会触发它的不存在。有什么建议吗？

SELECT
  InvoiceLineItemDescription AS ITEMNAME,
  VendorState
FROM InvoiceLineItems
JOIN Invoices
  ON Invoices.InvoiceID = InvoiceLineItems.InvoiceID
JOIN Vendors
  ON invoices.VendorID = Vendors.VendorID
WHERE InvoiceLineItemDescription = 'cover design'
OR NOT EXISTS (SELECT
  InvoiceLineItemDescription
FROM InvoiceLineItems ili
JOIN invoices i
  ON i.InvoiceID = ili.InvoiceID
JOIN Vendors v
  ON i.VendorID =
  v.VendorID
WHERE VendorState = 'Ca')





Invoices Table:
          VendorID | InvoiceNumber | InvoiceDate | InvoiceTotal | PaymentTotal | CreditTotal |
         TermsID | InvoiceDueDate | PaymentDate | ________________| ________________
            Vendors table VendorID | VendorName | VendorAdress1 | VendorAdress2 | VendorCity |
     VendorState | VendorZipCode | VendorPhone |__ VendorContactLName | VendorContactFName 
| DefaultTermsID | DefaultAccountNo | 

            InvoiceLineItems | InvoiceID | InvoiceSequence | AccountNO | InvoiceLineItemAmount |
         InvoiceLineItemDescription |
