问题 Ok, Firstly Hey. Technically i am new to this site, however i have been using it as a resource for a few years, and it is only because i am stumped that i now come in need of your aid. I have a VB script that is Querying the Db, filling the intended boxes with the string and displaying it. My issue is that when i try to use the Update SQL command, it completes however it does not update the DB when i manually check. Dim con As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet

问题 I can't find the solution to my problem. So I asked. con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source = " & Path.Combine(Application.StartupPath, "piglets.accdb") I was using Access 2010. It was working fine, with me and other PC's. Then I needed to change my database, it was given to me as a working sample from SO. piglets.accdb - This is 2010 too, I think. I opened it, worked fine, incorporated it to my newly created app, with the same exact code. It was working with me

问题 I'm trying to write a little form which accepts some user input, and on the basis of some logic displays one of two possible other forms. Everything is working fine if I use simple, unformatted data, but I hit a problem if the data in question has an input mask of a phone number. Presumably there's a trick here to ignore formatting characters or some such? The actual logic looks for records in a particular table whose values match the data entered. Something like this cut down example: A form

问题 Hi I am creating a table in MS Access to store the details of children in a school. I have a field called YearGroup which needs to calculate the school year they are in based on their date of birth and whether they have been moved up or down a year. I.e. if the expression deems they are six years old they should be placed in year 2. If they were moved down or up a year they should be in year 1 or 3 (this is based on another field in the table called YearModifier). The code I have at the

问题 I am trying to update a column in one table to set its value to the count of records in another table. This produces the error: Operation must use an updateable query. Query: UPDATE Tracking SET BatchCount = (Select Count(*) from Batch) WHERE ReportingDate=Date(); It seems Access does not like the Select Count(*) from Batch sub-query. If I replace it with a literal value, it works fine. Any suggestions to resolve this issue is much appreciated. 回答1: Unfortunately this is an inherent

问题 I'm trying to do an UPSERT (since that's what it appears to be called) and I'm getting an error: Microsoft JET Database Engine error '80040e14' Syntax error (missing operator) in query expression ... UPDATE myTable SET Field1='10', Field2='11' WHERE Date = #06/05/2013# IF @@ROWCOUNT = 0 BEGIN INSERT INTO myTable (Field1, Field2) VALUES (10, 11) END 回答1: Your code is using T-SQL (SQL Server) syntax that Access SQL does not understand. The VBA equivalent would be: Dim cdb As DAO.Database Set

问题 In MS Access 2007, I want to switch between datasheet and form views, without filtering, and remain on the current record. Should I use a bookmark ? How ? or How might I place a button on the ribbon to switch views, without having to search for the record or use a filter. I need this to run Access 2007 Runtime, since it will be implemented on a non-licensed computer. Seems some of the ribbon butttons & groups are not showing even if defined: I tried the "GroupViews" and "ViewsModeMenu"
