SELECT 
  [Stock Inventory].MaterialNumber, 
  [Stock Inventory].[Optimum Stock] AS Optimum_Stock, 
  customerservice.Part, 
  customerservice.SamplesRequired, 
  customerservice.Frequency,

FROM 
  [Stock Inventory] 
  INNER JOIN customerservice 
    ON [Stock Inventory].MaterialNumber = customerservice.Part

Answer 1

由于您提到需要从两个表中删除，您可以执行以下操作：

begin transaction

declare @deleted table (MaterialNumber int) --whatever data type you need
DELETE s
output deleted.MaterialNumber into @deleted
  from [Stock Inventory] as s
  INNER JOIN customerservice as c
    ON s.MaterialNumber = c.Part


DELETE c
from customerservice as c
join @deleted d
    on d.MaterialNumber = c.Part    

commit transaction
