问题 I have a listbox in Access with the ability to select from three items. When I close the database the listbox does not save the item which I selected, but reverts back to the first item in the list of three. How can I save the selection I made when I close and reopen the database. I know there is a way to have a default selection, but I'd like to keep my latest selection, instead of it reverting to the default. Thank you. 来源： https://stackoverflow.com/questions/28676459/keep-listbox-selection

I have the 2 dates on each record (from date - to date) and want to query the count of weekends. 回答1: The following VBA function will allow you to run Access queries of the form SELECT CountWeekendDays([from date], [to date]) AS WeekendDays FROM YourTable Just create a new Module in Access and paste the following code into it:

问题 I want to run a SQL query to copy a row from my table to either the same table or another table. Whichever method I use, I end up with a message telling me something similar to "You can't run an INSERT INTO query if it contains a multi-value field" (translated from french) I tried using SELECT * INTO, but the result is the same. My table is about reports, which can have a revision (hence the row copy), and they can have an attachment like for ex. a pdf file. so, how do you / can you copy a

问题 I know that in MSSQL when you load a trigger onto a table, that you have access to a "cache table" of the record(s) to be operated on (Update, Insert, Delete). Is there a similar mechanism to utilize from Access? If not, if i want to enforce a 1:1-M from a base table to the Join Tables, how would i do this? Tried using their "Oh so useful" Relationship Schema, but since i cant find a "unique" index for the PK's i setup and indexed, i cant use the trickle-down delete portion of the Enforce

问题 I'm having troubles with looping through Excel file from Access.

问题 I have a query (in MS Access 2013) that gives me the Sales for various Items by Date, for each day for the next 12mo. In another table, I have each Item with its known purchasing leadtime, say between 30 and 90 days. I created a query, and for each Item, I calculated the future date according to the leadtime, using: FutureDate: DateAdd("d",[Leadtime],Date()) I validated all Items exist in the Sales query, and all FutureDates are within the records that exist in Sales. I need to calculate the

问题 I'm hoping there is a fairly easy answer to this question. Perhaps using VB. I have a table in access called 'customers'. Each customer has an assigned franchise name in a column called 'franchise' on this table. I need to supply all franchises a csv file containing all the customers assigned in their franchise from the customer table. The long winded way would be an individual query for each franchise(select * from customer where franchise = 'New York'), but there are over 50 different

问题 So i have a very large data set on a server that i need to shrink. I have a list of names in a table locally on my computer with ms access. I want to create an inner join from my small local table to this huge server table. I was thinking I would just do a pass through query in ms access and inner join the two tables, but when i do a pass through query MS access can't find my local table (it only recognizes the tables on the server). How can i join the two? Here is my current code: select
