多部分标识符无法绑定4

Question

I am trying to join a series of tables but have encountered an error. I have tried applying other Stack Overflow answers to my problem, but to no avail. I'm very new to SQL.

select gbkmut.artcode, gbkmut.warehouse, gbkmut.facode, Items.costpricestandard,  ic.DateStart, SUM(aantal)as stockQty  

FROM gbkmut
INNER JOIN Items AS ic ON ItemNumbers.ItemCode=ic.ItemCode
INNER JOIN Items ON Items.GLAccountDistribution = gbkmut.reknr 

Below is my error

The multi-part identifier "ItemNumbers.ItemCode" could not be bound.

If it's not clear, gbkmut , ItemNumbers , and Items are the tables.

Answer 1

You have specified ItemNumbers.ItemCode in ON clause but you have not used ItemNumbers table in any Inner join.To use ItemNumbers.ItemCode you need to inner join with ItemNumbers Table.

FROM gbkmut
INNER join ItemNumbers ON condition
INNER JOIN Items AS ic ON ItemNumbers.ItemCode=ic.ItemCode
INNER JOIN Items ON Items.GLAccountDistribution = gbkmut.reknr
