SubQuery
Hello All,
I need a list from all the Items in the Inventory, the last date each item was last sold, and the qty sold. Doug Steele told me to use a subquery, it works fine with one table but when I have a Header and a Detail table and using the INNER JOIN, the system doesn't let me add the aliases table name (AS A). Error msg "Syntax error missing operator in query expression". This is my code, SELECT [Invoice Detail].StyleNo, Invoice.Date AS DateLastInv, Sum([Invoice Detail].Qty) AS QtyInv FROM Invoice INNER JOIN [Invoice Detail] ON Invoice.InvoiceNo = [Invoice Detail].InvoiceNo AS A (AS A, error message) GROUP BY [Invoice Detail].StyleNo, Invoice.Date HAVING (((Invoice.Date) In (SELECT Max(Date) FROM [Invoice] WHERE [Invoice Detail].StyleNo=A.StyleNo))); Please let me know Thank you abe |

Abe -
You don't really need the alias, but you can use it. To use the 'AS A' in the FROM section of a SQL statement, it must appear after a table name, thus giving the table an alias name. If you want the Invoice table to be referenced as A, then the SQL should be this: SELECT [Invoice Detail].StyleNo, Invoice.Date AS DateLastInv, Sum([Invoice Detail].Qty) AS QtyInv FROM Invoice AS A INNER JOIN [Invoice Detail] ON Invoice.InvoiceNo = [Invoice Detail].InvoiceNo GROUP BY [Invoice Detail].StyleNo, Invoice.Date HAVING (((Invoice.Date) In (SELECT Max(Date) FROM [Invoice] WHERE [Invoice Detail].StyleNo=A.StyleNo))); -- Daryl S "Abe Katz" wrote: Hello All, I need a list from all the Items in the Inventory, the last date each item was last sold, and the qty sold.
