阅读更多关于 how to export Access 2010 data macros

问题 I need to transfer Access data macros from my test db to my production db. Anybody know how to do that? I know that transferring tables from one accdb to another will also transfer the data macros, but that's not an option in my case. I also know I can recreate them manually in the production accdb, but that leaves me open to errors and requires taking the production database down for a longer time than would a scripted transfer scenario. If I only had to do this once it wouldn't be such a

Why is my query not updateable?

阅读更多关于 Why is my query not updateable?

I'm trying to build an updatable view in Access for a user. Basically, the underlying tables look like this: Accounts -------- accountId accountName accountHolder TransactionStatements ------------ statementId accountId received month year The user wants a Query (view) that looks like this: StatementView ------------- accountName accountHolder year janReceived febReceived marReceived etc... The SQL to accomplish this is straightforward using a transpose, but the resulting view is not updatable. I've also tried doing multiple joins explicitly to accomplish this: PARAMETERS [Enter Year:] Long;

阅读更多关于 Convert Access image OLE Object into raw image byte array in C#

I can't seem to get an answer all together for my real issue Invalid parameter when retrieving image from DB So Imma try piece by piece. Working with Visual Studio 2012 in C# and MS Access 2010.

Difference between Microsoft.Jet.OleDb and Microsoft.Ace.OleDb

阅读更多关于 Difference between Microsoft.Jet.OleDb and Microsoft.Ace.OleDb

It has been a good number of years since I did some programming with Classic ASP and Microsoft Access where we used "Microsoft.Jet.Oledb" driver to access and display the data. I have been asked to do some work with accessing MS Excel data using "Microsoft.Ace.Oledb". I have found this to be part of the "Microsoft Access 2010 Engine Redistributable" download. I would like to know if "Microsoft.Jet.OleDb" has replaced "Microsoft.Ace.Oledb" driver and are essentially the same or are they completely different things? Also, do you normally get the "Microsoft.Ace.Oledb" driver when you buy MS

How to simulate UNPIVOT in Access?

阅读更多关于 How to simulate UNPIVOT in Access?

UNPIVOT is available in MS SQL-Server 2005, but AFAIK not in MS Access 2010. How can it be implemented with on-board means? For example, I have a table ID | A | B | C | Key 1 | Key 2 | Key 3 --------------------------------------- 1 | x | y | z | 3 | 199 | 452 2 | x | y | z | 57 | 234 | 452 and want to have a table like ID | A | B | C | Key -------------------- 1 | x | y | z | 3 2 | x | y | z | 57 1 | x | y | z | 199 2 | x | y | z | 234 2 | x | y | z | 452 Key 452 is a special case. Currently I do the rotation in OLEDB/ATL C++. Although it is fast enough I'm still curious. What is the most

Is it possible to pass parameters programmatically in a Microsoft Access update query?

阅读更多关于 Is it possible to pass parameters programmatically in a Microsoft Access update query?

I have a query that's rather large, joining over a dozen tables, and I want to pull back records based on an id field ( e.g. : between nStartID and nEndID ). I created two parameters and tested them as criteria and they work fine. The issue is, I need to run an insert query from this main query, and need the parameters where they are, in the main query. So, I need to pass parameters to it programmatically. Anyone have a clue as to how this can be done? Thanks. I just tested this and it works in Access 2010. Say you have a SELECT query with parameters: PARAMETERS startID Long, endID Long;
