问题 I am using Access and have this SQL SELECT land.id, land.official_name, vaksiner.vaksiner FROM land INNER JOIN (vaksiner INNER JOIN land_sykdom ON vaksiner.id = land_sykdom.sykdom) ON land.kort = land_sykdom.land ORDER BY land.official_name The SQL gives me a result like this: id official_name vaksiner 1 a A 1 a C 2 b A 2 b B 2 b C But I want to combine the result so that it looks like this: id official_name vaksiner 1 a A, C 2 b A, B, C 回答1: See Allen Browne's ConcatRelated function

问题 I typed this code to create a view in a pre created database: CREATE VIEW NHTrips AS SELECT TripID, TripName, StartLocation, State, Distance, MaxGrpSize, Type, Season FROM Trip WHERE State = 'NH' ; When I try to run Access(2007) responds with a an error message: "Syntax error in CREATE TABLE statement." Why? 回答1: Access supports CREATE VIEW when you execute it from ADO/OleDb. This code snippet works because CurrentProject.Connection is an ADO object ... Dim strSql As String strSql = "CREATE

问题 I am trying to create a query in MS Access to ultimately take the output from this: Name Cat 1 Cat 2 Cat 3 Cat 4 Cat 5 Cat 6 Joe 2 12 10 1 0 0 Bob 0 0 0 0 0 0 Jody 2 4 3 1 2 0 Harry 0 4 14 0 2 0 To something like this: Name Joe Bob Jody Harry Cat 1 2 0 2 0 Cat 2 12 0 4 4 Cat 3 10 0 3 14 Is this even possible? EDIT SELECT [Authorizer Name], Sum([Q1A - CD # 1]) AS [Category 1], Sum([Q2A- CD # 2A] + [Q8A- CD # 2A] + [Q10A- CD # 2A] + [CTS A accurate- CD # 2A] + [e-correspondence A accurate- CD #

问题 It has been a long time since I have worked with MS Access and am not sure if I am doing this right. I have a Report bound to a query of single list of user names. The report groups on the user name and has a sub-report in the detail that is a chart. The sub-report/chart is based on a query that accepts a parameter of the user name. Since the sub report is not bound I need to pass the user name parameter from the main report detail onload event down to the sub-report and thus into the

问题 I have an application that uses Microsoft.Office.Interop.Excel to pull data from an Excel workbook. The information in the Excel workbook has been moved to an Access database, and I have been tasked to update the application, so that it will look for the data in the database. I found the Microsoft.Office.Interop.Access reference, but how do I use it to open the database and run queries? The documentation on this on MSDN seems to be somewhat lacking. Maybe I'm looking in the wrong place... :\

问题 How to connect to a Microsoft Access-based database in a Windows using JDBC code? What syntax is to be written for Type-1 and Type-4 types of the drivers?

If possible then also specify for the oracle also the driver syntax to be loaded.. 回答1: You can use JDBC-ODBC bridge by calling: Class.forName("sun.jdbc.odbc.JdbcOdbcDriver") Then you can use

问题 Hope you can help me. I am looking forward to programming my first MS Access AddIn with Visual Studio 2015 (a Ribbon-Bar as VSTO), but not having started I have to stop already. Visual Studio provides templates for almost every office product, but MS Access. I heard it is possible to "change" for example the Excel VSTO-Template so it can be used to develop an MS Access Ribbon. Does anyone know a good instruction how to handle this? How are you developing VSTO for MS Access? Thanks for your

问题 I am maintaining an application which currently checks to see whether MS Access 2007 is installed. It does this by verifying that a registry key exists. public bool IsAccess2007Installed() { RegistryKey rootKey = Registry.ClassesRoot.OpenSubKey(@"Access.Application.12\shell\open\command", false); return rootKey != null; } How would I go about verifying whether MS Access 2010 is installed? Or better yet, how would I verify that MS Access 2007 or later is installed? It is assumed that the user
