I am managing a traffic database and have currently constructed a series of queries that list average vehicle speed and total volume in five-minute intervals over the course of several months. From each of these queries, I need to create a subquery that, for each time interval, will simply average all speed values and sum all volumes into one record. Fields are: Time, Avg Of Speed, Sum Of Volume.
I created the subquery like so:
SELECT DISTINCTROW [Speed Weekday (2 SB)].Time, Avg([Speed Weekday (2 SB)].Speed) AS [Avg Of Speed], Sum([Speed Weekday (2 SB)].Volume) AS [Sum Of Volume]
FROM [Speed Weekday (2 SB)]
GROUP BY [Speed Weekday (2 SB)].Time;
When I attempt to switch to datasheet view though, Access locks up every time and I am forced to end the program through the task manager. The query I'm referencing [Speed Weekday (2 SB)] has only 4800 records thus far, so it isn't a ridiculous amount of data. Any advice as to what is going wrong? Thanks in advance for any help!
Yesterday my database crashed. It is the 'DEV' version for my application - so all of the current fixes/changes are in there and I have forgotten to backup!
It crashes when ever I try to enter the VBA editor, or build code. This occurred after a minor problem running some code (I forget which code).
The same occurs when I try to get into the code builder in the repaired version access generates...I have also tried using compact & repair to get in - but still no joy.
Can anyone offer any advice workaround to get this up and running again?
have a form that uses comb boxes. Now the combo box is Label "Tank Size" and looks up it's values in a Table named "Tank Size" and stores the one you pick say 2500. Now the problem. In the "Tank Size" table the row also has the price in the next column. So when someone picks 2500 in the combo box it will also list the price in say a text box or something next to the combo box. I hope i explained it o.k.
It seems to be quite simple really. Make a form for Orders and add a subform for Order items. Write some VB code to chage values on the Order form when an Order item is added or amended. Add a "Find" dropdown to the Order form to find particular Order numbers.
Run the form and add/amend orders and items. This will work OK. Move to the next or subsequent order using the "Next" button. Add/Amend again - no problem. Drop down the "Find" control, select an order and the correct order comes up on the form. Amend an item. As the code attempts to change a text box on the Order form Access crashes.
The same code (to add up the items, take off discount and add on tax) can be run after a "Find" by changing a "Discount %" text box on the Order form and this works OK. Perhaps the Order form needs to be in focus for the code to work but I cannot see why this should be so.
In fact you don't actually need the "Find" dropdown. Any code that moves to another Order record programatically will cause Access to crash when an item is added/edited subsequently.
Making it crash is simple but stopping it has cost me a couple of days of frustation. Has anybody any ideas?
My Access 2000 project crashed and the computer dutifully asked to report the error to Microsoft, so I let it run. I then looked at the subsequent screen and was surprised. Well - silly me, maybe I shouldn't have been.:mad:
This screen simply said that Access 2000 was in "extended support" and my "solution" was to upgrade to a newer version. This was a bit irritating since the purpose of reporting feedback is to provide an opportunity to fix program bugs. So why ask the user to provide an error report if that report will simply be ignored and only used for a sales pitch.
While Microsoft has every right to discontinue product development, I would hope that they would still try to fix bugs that cause a program to crash. I guess Microsoft's quality control department has been outsourced to the same company that Dilbert works for. Additionally, I find euphemisms, such as "extended support" for "You are out of any help options, tough luck" to be quite irritating. Why not directly admit that we are on our own.
Also I am still on a slow boil over over the last six years by the fact that help for DAO/ADO disappeared from Access 2000 help which was in Acess97 help and Microsoft never got around to making it available as an update.
So, my database appeared to be working OK yesterday however I occasionally saw an error in my "Update Event" script on one of my combo boxes. today, now when I try the combo box, I get a immediate crash.If im assuming its the same combo box, here is the code for that box:
Code:
Private Sub MCAcmb_AfterUpdate() Me.Model.RowSource = "SELECT DISTINCT [tbl].Record, [tbl].Model" & _ " FROM [tbl] WHERE Record = '" & Me.Recordcmb.Value & _ "' ORDER BY Model"
[code]...
I recently added a header...just tried it again and got the error:"The expression After Update you entered as the event property setting produced the following error:Object or class does not support the set of events."however I got it to work by entering VB, adding a space, removing it and then saving and entering the form view the form worked as normal. when i close and reload, i get the error again
I have a DB which has been up and running with no problems for a couple of months.
A couple of users have recently had new machines installed. These are XP SP2 with Office 2000.
The Database FE is on the PC and the Backend is on the server.
When FE is first downloaded and opened it runs fine. The second time you go in the DB gets by the Splash screen but then crashes on the Title Menu. If you then recopy the FE to the machine it opens fine the first time then crashes again on the second attempt.
I have checked the references and all ok. I have full error trapping on the Splash screen and the Title Menu yet I just get the error "Access has encountered an error and needs to close..."
It runs fine on my machine which is XP SP2 with Office 2002. Has anyone any suggestions that I can check or repair this?
focking pissed off. i want to add an image to a some forms, the database is all working and that. but when i put a picture in in the design view and then go to view it the whole thing crashs. i nearly lost the whole data base from putting one on the home page, thank fock i had a back up and now ionly have to redo one form as the other one wont open anymore it will just crash every time i try to open it. i have no idea whats going on, i have other images that i put on it before, but i cant put any on now. anyone every encounted this and how do i over come it!
I've been experiencing a very frustrating problem recently.
One of my databases crahes randomly, and I'd like to know if some of you have tips to helps me.
The database is splited in front-end and back-end, both on the server. I know keeping the front-end on the client PC will improve performance, but due to a high number of users (about 60 to 80) and the need of doing frequent updates, installing the front-end on each machines is not an option for now.
Users are not all directly connected to the server. Those who are directly connecte4d to the server (in building A) have no problem. Those who don't (building B) have extensive lags on opening (about 30 seconds), and on about anything that calls an heavy query, most often leeding to a crash. Access display the message telling that the datbase needs to be repaired and restart.
I tryed several thing to improve my queries, like eleminating most of GROUP BY and UNIQUE clauses and avoiding the use of functions.
I have a lot of conditional formatting in the forms, but I don't think this is the problem, since it is executed on the local machine (as far as I know).
My theory is that the lags cause some call to the DB to timeout. I just dont know how to fix that. Is there an option to higher the timeout delay?
My other theory is that the problem is caused by dropped packets during the connection to the DB. I tryed downloading large files (100Mb to 250Mb) from the server several times and never had a problem. Although the connection is quite slow, the ping is very small, like below 10ms to 20ms. Is there better ways to test a network connection, if possible without installing software (limited rights on the machine)?
Would using Replicas be a solution? What are the pros and cons of it? I never used them and know very little about it. My idea would be of putting a back-end on both servers, but I guess the data would not be as live.
BTW, I am using Access 2002 (2000 file format) on an XP SP2 PC.
Thanks to all of you patient enough to read all of this! I Hope some of you have some awnsers, tips or tricks!
My application crashes when trying to change the value of a text box in a continuous form. Here is the code:
Code: Private Sub cboPoCurrency_AfterUpdate() On Error GoTo ErrHandler Dim rst As Recordset
[Code].....
If I replace .txtUnitCost by MsgBox .txtUnitCost, it loops correctly through each record and returns the value. But if I try to change the value as shown in above code, MS Access crashes! (This is a desktop application with tables linked to SP lists - not a web app)
I've got a bit of a problem with linking a text box to a ComboBox. I have an employee name in a field [EmployeeName] that sits in the Header of a Form. (This is so I can show multiple records for that employee without having their name repeated at each one). I also have the name of contact [ContactName] that sits in the Detail area of the form.Both names come from their own tables that have all their contact numbers and e-mail addresses in columns I have linked the name to text boxes [ContactPhone] & [EmployeePhone] with their relevant phone numbers in within the Detail area of the form.
The ContactPhone that has the ContactName within the Details part of the form works well with no problems by putting =[ContactName].Column(1) in the Control Source
However when I put =[EmployeeName].Column(1) in the relevant Control Source (and / or EmployeeEMail in a second text box), once I have saved the form in Design view and returned to Form view, Access crashes and shuts down!If I remove the wording from the control source Access doesn't crash.
I have a database that runs a macro/report every 2 hours, however our network has been up and down lately. This causes the macro to fail when trying to log into the system because the table that is storing your username is no longer in the database. When I check, all tables, linked tables, forms, reports, macros and modules are all gone. I find the only way to get them back is to close the database and reopen.
What I want is a way to reconnect the objects without closing and reopening.
What is the best way to impliment a query in a form so that the user can view the query records, and have the option to print or save the selected record using command buttons?
I tried subforms but I could not get the command buttons to work in the subform after it went into the form, it wanted to print the entire form instead of the selected record from the subform.
So in a nutshell I have 3-4 queries that are built, and I want to have them show up on my form in a format that the user can scroll through the results and select a single record of the results and then print or save that individual record from the form, if such a thing is possible.
In some cases I create pass-through queries and use these in an Append or Make-table query to bring data locally.
All is well and fine until source data changes and the pass-through query runs too long and times out.
If needed, I can extend the timeout value in the Parameters of the pass-through query no problem, but when I try to open the Append or Make-table query in Design view to do the same, the pass-through query is first triggered and then throws the timeout, and I cannot access the Design view of the Append or Make-table
Is there a way to open an Append or Make-table query in Design view without invoking the source query?
I'm trying to run a UNION query that joins five queries through a MS WorkSpace into a DAO.recordset in VB. I'm pulling the data from a SQL Server Database through VB in Access. I'm attempting to open a recordset with a query passed to it as a string. The query is below. For some reason, I'm receiving a message: "MS Jet database engine cannot find the input table or query. Runtime Error 3078".
Here's what's puzzling. When I run a single query without any UNION statement, the code finds the table and runs fine without error, but anytime I join two or more queries with a UNION statement in the VB, it gives me the error.
I've executed the same UNION query in both Access Query Builder and SQL Server's Query Analyzer and they work fine in both environments. It's only when I call the query from a DAO.Recodset with VB that it causes this problem. The following is a sample of the UNION query joining two of the five queries. Does anyone have any idea what could be the problem? The following query executes in about 5 seconds so I don't think there's a "time-out" issue. I'm thinking that the UNION statement may be the culprit. Maybe there's another way to approach joining these separate queries? Any help would be most appreciated. Thanks.

I am wondering if there is a quicker way to export a query to excel then have the data in that query removed from the original table. (effectively cutting the data from the table and exporting to excel)
I understand that this can be done by exporting the query to excel then running the same query as a delete query to remove the data but I just wondered if this is the most efficient way.
I have experience of VB in excel but currently only use the basic macro builder in Access though if Access VB is more efficient I can easily learn.
I run a physical therapy office and patients come in for treatment either 3, 4 or 5 times per week. My database is used to track these frequencies (among other things).
I have 3 queries which count how many patients come in 5, 4 and 3 times/week.
In my main table I have fields called "how many 5's", "how many 4's" and "how many 3's".
I have tried to design an update query which will update those fileds in my main table to reflect the counts in the 3 queries mentioned above.
(I'm not using SQL view, I'm using the query design view)
In the "update to:" row, I use the Build function and locate the count I'm looking for.
Problem: when I run the query I get the error: Operation must use an updateable query.
The ProjRevMRC field is an expression that reads:ProjRevMRC: IIf([ProjRevDate]>=DateSerial(Year(Date()),Month(Date()),1),[CurrentMRC]*[qry303a_ SFADetailMRC_ONLY]![Rev Flow Through],0)
When I run the query, it works perfectly, but when I created a crosstab query to show totals by month, I wanted the totals to be zero for the months less than the current month. Is there a way for the crosstab query to execute the expression and put zeroes for those months?
I have a field that is giving me the number of business days between a period of time and then I want to subtract that number - the person's PTO time to see the actual days they were available...when I simply type the number in (see below) it works great but I want to set up a prompt that will ask me how many PTO Days to calculate as it will be different for each person I am quering...is this possible?
:confused: I am trying to help someone with a complex problem (so it seems to me) but I will first ask about what should be a simple thing....
First goal: to COUNT the number of times a TYPE of visit is made. There are several different TYPEs but only interested in tracking 2 of them.
When a crosstab query is created - if one of the 2 parameters are not "met", a blank is returned. I have been reading posts about using NZ and IIf IsNull, etc to get past that - but none of them make any sense to me and the Access help suggestions do not work. Hope someone can make it clear with this information: (can't give more specifics to keep privacy intact)
The SQL was written by Access not by me. :)
Here is an example of the Crosstab SQL (which is using a previous query):
TRANSFORM Count([qryTest2.TYPE]) AS CountOfTYPE SELECT qryTest2.CID FROM qryTest2 GROUP BY qryTest2.CID PIVOT qryTest2.TYPE;
----------- qryTest2 SQL: (Grouping by to remove dups)
SELECT DISTINCTROW tblM.CID, tblM.[M#], tblM.LNAME, tblM.FNAME, tblM.YMDBIRTH, tblC.ClDOS, tblC.TYPE FROM tblM LEFT JOIN tblC ON tblM.[M#] = tblC.[M#] GROUP BY tblM.CID, tblM.[M#], tblM.LNAME, tblM.FNAME, tblM.YMDBIRTH, tblC.ClDOS, tblC.TYPE HAVING (((tblC.TYPE)="Out" Or (tblC.TYPE)="In")) ORDER BY tblM.CID, tblM.LNAME, tblM.FNAME;
I'm building a report for annual software license renewals. The report data source is a query that combines the customer information, their computer information, and the licenses purchased for that computer. I am having no trouble with the form displaying the customer info page, then a page with the computer info at the top and a list of licenses purchased for that computer underneath.
That would be great, if that's what my boss wanted. However, she wants the whole list of available licenses displayed on each page, in the event someone want to purchase additional licenses with this year's renewal.
I'm trying to figure out how I can set up a query/report grouping to do that. I've tried making a new query, relating the qryLicense!licenseID to the qryPurchase!purchLicense and setting the relationship option to show all records from qryLicense and only those related from qryPurchase. I added the qryPurchase!purchCPU field to my query, hidden it, and set the criteria to “=1” (the computer ID of one of my dummy computer records). I also have a Sum of the qryPurchase!purchQty field included in the new query that I want to display the total number of that particular license purchased (and 0 if there are no corresponding records). All fields except for the quantity field are set to Group By.
What I’m getting from this is simply a list of the licenses purchased for that computer, not the complete list of licenses available showing the quantity purchased where applicable.
I am using an Access 2010 DB to keep track of a schedule. Essentially, at least one person needs to be signed up to work for every hour of every day in a week.
Tables: Days with 7 records Hours with 24 records Workers with as many people that sign up to work the different hours Schedule signifying the worker, day, and hour which are signed up.
As of now i have a query that relates these results and gives me a line detailing the worker/time information for the slots that are signed up for.What I'm TRYING to do is to create a query that gives me BLANK worker info when there is no one signed up for a particular hour.Currently my Schedule table has the following:
What I'm looking to do is have this table matched up with another table (or query) that provides every combination of day/hour. When an day/hour combination is skipped, the query will be able to "fill in the blank" with a row. Like this:
