问题 I need to open a specific form by a click on a subform record name. The name in the subform is showed as a combobox with ID and Name as columns. I did like this: Private Sub ID_Prodotto_DblClick(Cancel As Integer) Dim Id As Integer Id = Me.ID_Prodotto.Column.Value DoCmd.OpenForm "Prodotto", , , "ID_Prodotto = " & Id End Sub But Access requires me to manually insert the ID Field Value as I click on the record. Where am I wrong? 回答1: It should read: Id = Me!ID_Prodotto.Value or, if you wish to

问题 I have inherited a MS Access project that is way beyond me: Table A has exam data, so each field in A is the name of an exam item and the value is the points earned on that item. My task is to convert those results to Table B, which has one field for the item name and one field for the corresponding value. So it looks like this: Table A: A.Item01 A.Item02 etc. Table B: NameofFieldinTableA Result ...so if A.Item01 = 1, I'd like that to update to Table B as: NameOfFieldinTableA = Item01 Result

问题 I'm new to SQL and can't seem to ask the right question, as in every time I formulate it differently I end up with the same results: A query that groups data by several properties (users that share more than one property). I'm writing a JSP-based website on the Glassfish server, and manage the database from MS Access. What I'm interested in, is basically grouping by several distinct properties. Say I have a table that shows which items a user has. Something like this: id | name | item1 |

问题 I have a set of data spanning across 3 days. Based on the first column from the left, is it possible to have a query that calculates the average of the values in the third column from the left based on each day? The end result will be two columns: 1/1/2008 | 1.605 2/1/2008 | 1.59 3/1/2008 | 1.56 I think the logic will be something like in a loop: Based on the day in the first column, if it is the same day, count the number of rows and add up the values of the third column Use the sum of the

问题 any chance someone could enlighten me on why I'm getting an "Not a valid file name" error when trying to connect to MS Access database stored on Sharepoint? I have no issues with connecting to file on C:\ Set cnn = New ADODB.Connection MyConn = "C:\somelocation\database.accdb" With cnn .Provider = "Microsoft.ACE.OLEDB.12.0" .Open MyConn End With but when I change MyConn to Sharepoint address it doesn't work :/ MyConn = "https://some.website.com/somelocation/database.accdb" I'm getting a "Not

问题 I am not sure why this behaves this way. I need to select few values from two tables based on some criteria which should be clear from the query i tried below. query = @"SELECT n.borrower, a.sum, n.lender FROM Notification AS n, Acknowledgment AS a WHERE n.deleted=@del2 AND n.id IN (SELECT parent_id FROM Acknowledgment WHERE status=@status AND deleted=@del1)"; This returns more rows (12) than expected. I have two tables Notification and Acknowledgment both which have field "sum". When I try

问题 I have a join statement, like this: SELECT distinct(p.id), p.id, p.first_name as [First Name], p.last_name as [Last Name] FROM tbl_person as p , tbl_person_languages as pl WHERE pl.person_id = p.id AND pl.language_id in (12,14,...) but this returns all records. I would like to pull back the distinct record of an individual that has all values of pl.language_id, not just one or more values. I should note, the values in the IN statement may have 1 or more values Any ideas on how to do this? I
