Difference Performance Levels For Diff Users With Seemingly The Same Set-up?!
Aug 18, 2005
Afternoon Folks,
I have a database that multiple users have access to.
We all have new pcs of exactly the same spec.
We all have the same oracle ODBC, which is linking to tables in an oracle database on a Sun F15k Server.
The linked tables are set-up using my oracle account with saved password.
We are using the same network.
We are all using Access 97.
Queries that are run in this database are returning results in just a couple of seconds for other users, and 20-30 seconds for me.
Can anyone suggest any factors that may be causing this discrepancy?
Or things that I can run/do to improve performance?
Cheers in advance, James

I run a school library database (Access 2003) and want to set up a password logon system so that different users can get at different parts of the program - e.g. Administrator (everything), Librarian (can add and delete records but not change the database design), Student (can only access certain areas, read only).
I've tried using the security wizard to set this up, which seems OK until you then open the database again. I would expect to then get some sort of log-on screen next time I open the database, but instead it opens normally, but then won't let me do anything because I "don't have permission". I had to restore a back-up copy.
I must be missing something obvious here. Is there a place to look for instructions? Couldn't find anything useful in the help screens.

Hello,
First time poster here so I hope this doesn’t sound too remedial. Here’s my situation…
I work for a large industrial company that has locations throughout the world. We have a DB that tracks product concepts and ideas and associated metrics for those ideas. The DB resides on a file server in North America (Raleigh, North Carolina to be exact). North American users have no trouble with the performance of the DB. It takes a moment to open (several seconds), but once it has opened there is virtually no lag time to add or edit records, run reports, view graphs, etc. However, users in Germany and the Netherlands encounter substantial lag time not only in opening, but also in updating and entering records, running reports, and viewing graphs. This is true even after they have waited for the DB to open.
The size of the DB is only around 2MB so I don’t think overall size is the issue.
There are probably no more than 3 or 4 users in the DB at the same time with most occasions being a single user so I don’t think we are having a multiple user issue.
The DB is self contained – no references to external data or splitting of any kind.
So my questions are:
1. Do you think the poor performance is a function of our network or of Access or the DB design?
2. If it is the network, is there anything that I can do in Access to help get around the hardware/network issues?

Hi all,
I have an Access 2002 (SP3) frontend and SQL 2000 (SP3a) backend.
2 sites, 2 SQL servers ( identical hardware and software).
Replication using Push Merge every 5 minutes.
10 users at 1 site and 15 at the other with Access 2002 frontend stored locally on each users PC.
I get random 'object invalid or no longer set' messages just appearing on the workstation screen without the operator doing anything. about 3 or 4 a week, but not on the same workstation at 1 of the sites only, but only during the working hours of the other site. We have out of hours users who never experience this issue.
Occasionally the error is preceeded by a SQL ODBC connectivity error but this rare.
I had been informed it was network issue but I have been running continuous
ping from a suspect workstation to the sql server and back.
When the error occurs there are NO dropouts in the pings.
It doesn't follow volume of data changes either as one site can make hundreds of changes and we don't get the error and then it can be after 10 changes the error occurs.
I have been researching this now for about 2 weeks to no avail, if anyone can point me in the direction of good resources you will make my year. :D

Alright people... I'm ashamed to even ask but here goes.
I have two tables:
1) Employees
2) Neighborhoods
Table Employees has a comprehensive list of all employees and their information (including phone numbers).
Table Neighborhoods has lots of information about each neighborhood we're working in and it also specifies what people play certain roles in each neighborhood. For instance, there is a field for "Field Manager" and "Sales Consultant". These two fields are exact matches of "Full Name" from Table Employees.
All I want is for my Neighborhoods Table to be updated or a new table be created that imports the "Field Manger Phone Number" into the Neighborhoods Table and the same for the "Sales Consultant".
-----------------------------
To be explain one other way, this is what I want:
Table: Employees
Field: Full Name
Field: Phone Number
Table Neighborhoods
Field: Field Manager (already equals Full Name)
Field: Sales Consultant (already equals Full Name)
Field: Field Manager Phone Number (This is the field I want pulled from Table Employees)
Field: Sales Consultant Phone Number (This is the field I want pulled from Table Employees)
-------------------------------
I've tried my best to create an Update Query or a Make Table query but I have not gotten any good results. Can someone please help me out with this being very descriptive as I am certain I'm just goofing one simple step.
Thanks in advance.

I have two forms:
frmOpeartions
frmManagers
frmOperations allows the user to assign a manager to an operation by selecting the manager record from a combobox. Occasionally the user may need to setup a new Manager record if one hasn't been setup already. In this case there is a "New" "button" (it's actually a label with an on click event) that the user can click to open frmManagers and add the new manager record.
The code to open frmManagers is:
Private Sub lblNewManager_Click()
DoCmd.OpenForm "frmManagers", acNormal, , , acFormAdd, acDialog
Forms!frmManagers!cboMoveTo.Visible = False
Forms!frmManagers!lblManagers.Visible = True
End Sub
Once frmManagers is open the user creates the new Manager record and then closes the form using a similar label with an on click event:
Code:
Private Sub lblClose_Click()
DoCmd.Close acForm, "frmManagers", acSaveNo
End Sub
frmMangers also has an OnClose event that will refresh any comboboxes on other forms that refer to tblManagers to make sure that new Manager records will be available immediately for the user to choose from:
Code:
Private Sub Form_Close()
If CurrentProject.AllForms("frmPlants").IsLoaded Then
Forms!frmPlants!cboPlantManager.Requery
Forms!frmPlants!cboQCManager.Requery
[Code] .....
So the problem comes when the user clicks the Close label (acting like a button) on the frmManagers. The code successfully closes the form and the on close event successfully refreshes any comboboxes on forms that may be open, but then for some reason it attempts to run again or perhaps continue running the onClick event that opens frmManagers. Since the form is already closed it gets hung up on trying to change the visible properties of the controls and the code fails.

hello, i have checked out the forum for pevious Q's to this problem and found the below.
http://www.access-programmers.co.uk/forums/showthread.php?t=80692&highlight=compare+tables
only problem is thats its writen at a bit too technicle a level from where i am. i've done some investigation into the problem though.
found out i need to use the docmd.transferdatabase function to import the tables i need to compare into my current db.
my question is this. how does it import them, does it create new tables within the current db or is it put somewhere in temp memory for use only while db is open, not sure how it would work. ideally i would like it to import tables, do the table comparison then create a report of the differences or make a new table showing the differences, then it reverts back to how it was before i imported it. i.e. he current databse is unchanged except for maybe a new report or new table (the results).
thank you for any advice.

Hello,
I am having problems creating a Exp to show the difference in time.
I am currently using :Expr1:DateDiff("n",[TimeReported],[TimeDefectGiven]) which is returning a figure in decimal.
If the answer was to be 90 minutes i need it to return the figure as 1.50 instead.
I have looked on the site using Date Diff and Time without success
Any help given would be great

hi everyone, i have a table of timeseies data and would like to run a query working out the difference between the current row's value (day) and a previous row (day, or days before) and put this difference in a new column in the resulting query.
I know it would be straight forward in Excel to run a formula between 2 different rows, but this table has >1 million records and are appended with new records regularly.
Any help or inspiration would be greatly appreciated!

I have a date field, I am trying to have my query only pull the records that have a date entry that is within and up to 90 days from today or Now. For this query all other records are irrelevant.
THis is what I have found so far
=(Abs(DateDiff("y",Now(),[ls_Exp Date])))
Can someone show me how to add the 90 days in there?
Thanks.

I'm using the date diff .... DateDiff("h",[Start time],[End time]) in a query and then I report the results in a report. I have run into a problem for the first time. I had a start time of 7:00pm, and an end time of 7:00am. This was calculated in the query as (-12) which is messing up my cost formula.
How do I resolve this?

Friends,
I have a problem with a date diff calculation:
On my form I have placed two controls, a text box and a check box.
The textbox contains is a date field (mm/dd/yyyy).
What I need is a code that checks the checkbox if the date in the textbox is within the last 12 months.
This is the code I am using but not working:
If DateDiff("yyyy", textbox, Now()) >= 1 Then
Me.check1 = "yes"
End If
Any help? Thanks.

Hi hope someone can help. Thankyou in advance.
I have a small database for my warehouse that sells washing machines, fridges etc.
I am trying to get a grip on the stock control.
What I am looking for when a order is filled out on our order form is the stock number will reduce by the amount sold. Not sure how to make this happen.
I have the number of units in stock under the products table
ProductsID PK
ModelNumber
UnitPriice
Description
QuantityInStock
Sounds simple but for some reason I cannot figure it out.
Thanks

hello, i am new to this forum. i have been struggling on a project i am doing where i am tring to calculate the stock levles and keep track of them along with the re order level
i have calculated the current stock levlel, in a query called "stock level 3"
Here the total amount prodcuts sold are taken from the field called stock level.
Here is a break down of my original tables
CUSTOMER
Cu ID
And all their personal details such as contact details
CUSTOMER ORDER
This is where the order takes place and contains the following information
Order_ID
Cu_ID
Staff_ID
Order_Date
Required_Date
Recievied_Date
Order_Total
Delivery
Delivery costs
Overall discount
Type-Of_Purchase
Paid
Money_Owed
Final Costs
CUSTOMER ORDER DETAILS
Here is the specific details of one order.
Order_ID
Prod_ID
Qty_on_Order
Discount
Line_Total
PRODUCTS
Prod_ID
Supp_ID
Product_Name
Product_Type
Prod_ Unit_Details
Qty_in_Stock
Re_Order_level
Price
Unit_Cost
Manufacturer_ID
Shelf_Life
SUPPLIER TABLE – with detaisl e.g Supp Id and account number
SUPPLIER ORDER

Type-Of_Purchase
S_Paid
Supp_Final_Costs
SUPPLIER ORDER DETAILS
Supp_OrderID
Prod_ID
Qty

QUERIES
•In the query “All customer order details”, I have worked out the line total for each prodcut with in one order. I have timed the Qty_on_Order (customer order details table) by price (in the produt table) and by the discount(customer order details) this then gives the line total
Now to update the stock level I made a new query called “stock level Query”, where I added up the total number of each products sold, by adding the “Qty_on_Order” from the query “All customer order details”
I then made a new query called “stock level 2” where I calculated the amount left on the shelves by taking “SumOfQty_on_Order” of each product from “Qty_in_Stock” (form prodcuts table) to produce the field called “Qty_in_Stock”
I then made a new query called “stock level 3” where I inserted the same fields but an extra field called “Re_Order_level” for some reason could not add this to the query "stock level 2"
So far the system can add up the total number of products sold, for all the orders, and then automatically calculate the Qty_ in_ stock by taking away the “SumOfQty_on_Order” once a new order is made.
I then made forms where I go in my form to “customer”" and then to “making new order”.
Below is a sub form called “all customer order details sub form” . Here orders are made with defining "Qty_on_Order
I want to make a system which calculates for me i have ordered more stock then there is.
Howcan i now when i make sure when i place a new order in the query"All customer order details" , that if i order above the number of "Qty_in_Stock" (from query srock level 3), from the query “stock level 3”, that when I order more products then ““Qty_in_Stock”, in the query “stock level 3”, does not allow me to enter this and if it is possible please can you insert error messages on it.
I do not know if this helps .- I can not make the “Qty_in_Stock”, to appear in the actual table “Products”.
At the moment I can only update this in the query “stock level 3”. I am not sure if I need this so I can then set re order level which then comes up with an error message telling me when the re order level has been reached. -
As later on I will need to add on any products brought in from the suppliers to the Qty_in_Stock”, in the products table to be automatically updated.
"stock level 3".
here are the fields
Code:
Prod_ID (Products)
Prod_Name (Products)
SumOfQty_on_Order (from "stock level Query")
Qty_in_Stock: Products.Qty_in_Stock-[SumOFQTY_on_Order]
Re_Order_level (Products)
here are both sql from both queries
All customer order details
Code:
SELECT [Customer Order Details].Prod_ID,
Products.Price,
[Customer Order Details].Qty_on_Order,
[Customer Order Details].Discount,
(Products.Price*[Qty_on_Order]*
(1-[Discount])/100)*100 AS Line_Total,
[Customer Order Details].Order_ID,
Products.Prod_Name,
Products.Prod_Type,
[Customer Order].Cu_ID
FROM [Customer Order] INNER JOIN
(Products INNER JOIN [Customer Order Details]
ON Products.Prod_ID=[Customer Order Details].Prod_ID)
ON [Customer Order].Order_ID=[Customer Order Details].Order_ID
ORDER BY [Customer Order Details].Order_ID;
stock level 3
Code:
SELECT [All customer order details].Prod_ID,
Products.Prod_Name, [stock level Query].
SumOfQty_on_Order,
Products.Qty_in_Stock-[SumOFQTY_on_Order] AS Qty_in_Stock,
Products.Re_Order_level,Products.Prod_Name,
[stock level Query].
FROM (Products INNER JOIN [All customer order details]
ON Products.Prod_ID = [All customer order details].Prod_ID)
INNER JOIN [stock level Query]
ON Products.Prod_ID = [stock level Query].Prod_ID
GROUP BY [All customer order details].Prod_ID,
SumOfQty_on_Order,
Products.Qty_in_Stock-[SumOFQTY_on_Order],
Products.Re_Order_level;
please may help me and gice m,e soem tips it will be much appreciated or website/downloads.

I'm sure there's an easy solution to this somewhere...
I have a query that is supposed to assign a wage to a production job if the range output falls within a certain percentage range. For example, if they produce 125% to 130% of their goal, their wage is 15 cents higher. If it's between 130% and 135% of their goal, their wage is 30 cents higher. There are about 20 ranges that my bosses want set up. Short of making the longest Iif-Then-Else statement in history, does anybody have any suggestions? Should I use a separate table and somehow try to integrate it into the query?

I've got a table in which there are 20 numeric columns. For one report, I want to add all of the data in those columns together. I used the expression:
Seats: Sum(DailyActivity!PkgSeq01Cnt+DailyActivity!PkgSeq 02Cnt+DailyActivity!PkgSeq03Cnt+DailyActivity!PkgS eq04Cnt+DailyActivity!PkgSeq05Cnt+DailyActivity!Pk gSeq06Cnt+DailyActivity!PkgSeq07Cnt+DailyActivity! PkgSeq08Cnt+DailyActivity!PkgSeq09Cnt+DailyActivit y!PkgSeq10Cnt+DailyActivity!PkgSeq11Cnt+DailyActiv ity!PkgSeq12Cnt+DailyActivity!PkgSeq13Cnt+DailyAct ivity!PkgSeq14Cnt+DailyActivity!PkgSeq15Cnt+DailyA ctivity!PkgSeq16Cnt+DailyActivity!PkgSeq17Cnt+Dail yActivity!PkgSeq18Cnt+DailyActivity!PkgSeq19Cnt+Da ilyActivity!PkgSeq20Cnt)
Where dailyactivity is the name of the table, and pkgseq01cnt is the name of the first column, etc.
The expression returns the number 961.
If i make a query where i sum all of the columns individually, and then a query based off of that query where i add all of the sumed columns together, i get the number 965. (which, as far as i can tell, is the right number)
the expression in the second of those querries is:
Seats: Sum([seat]![SumOfPkgSeq01Cnt]+[seat]![SumOfPkgSeq02Cnt]+[seat]![SumOfPkgSeq03Cnt]+[seat]![SumOfPkgSeq04Cnt]+[seat]![SumOfPkgSeq05Cnt]+[seat]![SumOfPkgSeq06Cnt]+[seat]![SumOfPkgSeq07Cnt]+[seat]![SumOfPkgSeq08Cnt]+[seat]![SumOfPkgSeq09Cnt]+[seat]![SumOfPkgSeq10Cnt]+[seat]![SumOfPkgSeq11Cnt]+[seat]![SumOfPkgSeq12Cnt]+[seat]![SumOfPkgSeq13Cnt]+[seat]![SumOfPkgSeq14Cnt]+[seat]![SumOfPkgSeq15Cnt]+[seat]![SumOfPkgSeq16Cnt]+[seat]![SumOfPkgSeq17Cnt]+[seat]![SumOfPkgSeq18Cnt]+[seat]![SumOfPkgSeq19Cnt]+[seat]![SumOfPkgSeq20Cnt])
where 'seat' is the name of the first query that sums the columns.
I think those two ways should both come up with the same number - but i can't figure out why the first way is missing four! there are thousands of rows so it is hard to go through the table itself. Also, in both of those ways, the querry includes a 'where' column which limits it to rows where another column equals a certain word - but that's relatively straight forward - dont' know why that would make it different.
any ideas?
Thanks! It's driving me crazy!

hi
i have a database to manage utility bill payment , it consist of
- Bills :
- billID
- Benificiary Name
-Cost Center
- Bills Transaction :
-TransID
-bILLid
-BillDate
-BillAmount
-Payment Transactions :
-PayTranID
-bILLid
-PayAmount
-PayDate
-BankRef
i made a union query from Bills Transaction and Payment Transactions to calculate bills balances which is : billid,sum(Bills Transaction.BillAmount)-sum(Payment Transactions.PayAmount)
all is working well , but the problem is i cannot find any relation between billtransaction
and billpayment ( per bill ) , cause i wish to payment details for each single bill transaction
the normal case is : bills issued as monthly basis but may fully or partially pay as the following cases :
- each bill transaction may fully pay one time
- in some cases : each bill transaction may fully pay but in multi settle
- multi bill transaction (per BILLID) may fully pay one time
IN CONCLUSION : each bill transaction should be stteled fully within one or two or maximum 3 months , say bill balance for each bILLID shall be zero.
how i could find a relation between this two transaction ( bills and payment ) to preview
payment information for each single bill transaction
exapmle :
billID : 39
BILL Transaction BillPayment BillsBalance
Bill Date - Amount PayDate- Amount

I need to know how to set up a form with three tabs, all of which having the same text boxes or method of data input. I want each tab to write the information input into different rows on my table corresponding to the tab (the tabs will correspond the the first column on the table). I have three rows on my table for three companies. I want a form that has a method of gathering the data for each company and writing that data to the corresponding row. I can set up the form with three tabs, all requesting the same info, but I don't know how to connect them to the corresponding rows.

I am having a problem with a datediff expression.I have a query that pulls the first date and the last date out of a list but are put in seperate fields. I thought I could build an expression for datediff to calculate the number of dates between them. I can't just put in the dates because they are constently changing.The expression I have is:
[datediff("d",[min/max edging unit #2]![firstofupdate/time by month],[min/max edging unit #2]![lastofupdate/time by month])]
