Using math functions in Sql with MS Access

阅读更多关于 Using math functions in Sql with MS Access

问题 I designed a query in SQL View using MS Access: select floor(num1) from t1; When I run it, I get "undefined function floor". I get similar errors for Ceil , Mod , Power , Sign , Sqrt , Trunc , and initcap functions. Does the Access database engine's SQL syntax have equivalent functions? 回答1: Replace Floor() with Int(). I learned this by searching in the Access help files, in this case, hitting F1 while in the query designer, and searching for "functions." That took me to a help topic

Duplicate each row pulled in and add an extra field counting up one day between a given start and end date

阅读更多关于 Duplicate each row pulled in and add an extra field counting up one day between a given start and end date

问题 I'm using Microsoft Access and I want to create a query that duplicates each row pulled in from a table with an extra field added on counting up one day between a given start and end date. So if there's 4 days between the start and end date there's 4 duplicate rows returned for each record with only difference being the added date field counting up 1 day. Is this actually possible to do? 回答1: This task is fairly easy if you have a calendar table which includes a row for each date you need.

Automate build of Access 2007 database

阅读更多关于 Automate build of Access 2007 database

问题 As part of our build process we have to create an Access ACCDB (2007) database. The database constitutes the current front-end of our application and must be (for other reasons) build during the initial phase of the build process. Currently, this is a manual process which I'm hoping to automate. Our database consists of MANY tables, formulas, queries, etc. I believe we're actually close to the limit of what Access is actually able to handle so we try not to add anything further to it. I've

Force Report Footer to be at bottom of page

阅读更多关于 Force Report Footer to be at bottom of page

问题 In Microsoft Access 2007, Is there a way to display the Report Footer section at the bottom of the last page? Right now my Report Footer section always follows my Detail section, so it ends up anywhere. I would like to avoid using VBA as much as possible. 回答1: Does it have to be the report footer, or is the requirement that you wish text to appear at the bottom of the page on the last page of the report? If so, then it can be done with very little VBA: Private Sub PageFooterSection_Format

OpenFileDialog in vba that returns the directory as a string

阅读更多关于 OpenFileDialog in vba that returns the directory as a string

问题 I have been looking everywhere and I am very surprised that this is not already easily available as a function in VBA. I need a function that when called, opens a filedialog where people can select 1 file (not more, just 1) and then the function returns the location of the file (including filename+extension) as a string. At first i thought: " How hard can that be, I'ts really simple in VB.NET.." Thanks in advance! 回答1: You mean like htis? Sub Sample() Dim ofD As Object Dim Fil Set ofD =

Compiling an Access 2007 accdb into accde

阅读更多关于 Compiling an Access 2007 accdb into accde

问题 I'm trying to use the built in Make ACCDE functionality in access to make a standalone application that interfaces to an SQL-Server 2008 back end. When I run the Make ACCDE I receive an error that states that too many TableID references are being used (the limit is stated to be around 2048). Through trial and error (deleting forms until it compiles) I've discovered which form is causing the issues. It seems to compile if I delete all the VBA code from the form. I was wondering if anyone has

问题 It would be nice if there was a right-mouse-click menu on the edit panel to change the font size, but there isn't. Is there a system setting somewhere else that lets me increase the default font size? 回答1: Office Button > Access Options > Object Designers > Query design > Query design font 回答2: Quick note, be sure to restart Access to allow the updates to take effect. 来源： https://stackoverflow.com/questions/1599064/is-it-possible-to-change-the-font-in-the-sql-edit-window-in-access-2007

Version control Access 2007 database and application

阅读更多关于 Version control Access 2007 database and application

问题 I need to version control a Microsoft Access 2007 database and application. Currently everything is contained in a single mdb file. The application includes: Forms VBA code Actual database I would assume I need to separate the database from the forms/code. I would like to be able to version control the forms/code as text to support version diffs. At the moment I don't have access to SourceSafe (I heard there may be some access support) so I would prefer a solution that would work with

Why is my VBA for MS Access Buggy?

阅读更多关于 Why is my VBA for MS Access Buggy?

问题 This is kind of a vague question and hard to explain. I'm trying to code my access database, but the VBA portion is really annoying me. Whenever I type something and hit space, it will automatically redo that space and put me back up against the previous word i was typing. Also, Intellisense will come up for a split second, flicker and go away, and revert my cursor to the text that I was just typing. This results in me constantly typing things in places where they shouldn't be and a lack of

Limit # of records returned based on a form control

阅读更多关于 Limit # of records returned based on a form control

Is there a way to limit the number of records returned in a query based on the user input in a text box? I know that I could use the Top Values if the number of records were constant, but this number will change. I tried: SELECT TOP[Forms![frm_GenerateMailout]![MailoutSize]] ..but that didn't work. It depends how, and where, you are using the SQL statement, but if you construct it as a string you need to concatenate it correctly: "SELECT TOP " & Forms!frm_GenerateMailout!MailoutSize & ".. etc." "Is there a way to limit the number of records returned in a query based on the user input in a text
