Query Has Become Slower
Oct 4, 2005
I've got a database with 1.5 milion orders. In those orders there are also customer information. Now i want to filter the customer information. In a older backup from my database when i run the query i takes about 22sec. But my new database it takes 2 min. (Both have 1.5 milion orders).
I haven't got a clue why i've got this problem. I've put some indexes on the table (didnt work) so i deleted the indexes from the table. I also put some relations to the tables.
But the strangest thing is that the status/progres bar in the leftbottom screen go's immediately to the end of the bar, and there it stops for 2 min,
The old db does this in steps...
My operating system is winxp with sp2
And access xp
I also want to know if it is possible to get clusted indexes in access. Because i cant get the integrity in the relationship diagram. (the database isn't normalised this is because i didnt make the database)
I'm sorry for my crappy English.

I have an access db with a linked table (to Sharepoint) which contains about 15000 records. I have to copy those records to the local access db. To do this I have a bit of VBAcode. It works, but for each next record that is copied it takes a bit longer. When starting the program the records are copied quite fast, but soon you see it slowing down until after a couple of thousand records it just goes too slow to be usefull, meaning it would take a lot of days to copy all records.
What I now do is let it copy 500 records and exit ms-access completely and then start it again and let it copy the next 500 records. This works but is tedious as I have to do it about 35 times. Why this gradual slowdown occurs?
The VBA code is pretty straightforward.(I use VBA because I do a bit of data wrangling while reading in the values of the records)
Code:
Dim importdb1 As DAO.Database
Dim rsimportdb1 As DAO.Recordset
Dim i As Double
Set importdb1 = CurrentDb
Set rsimportdb1 = importdb1.OpenRecordset("2015")
Set rsMain = CurrentDb.OpenRecordset("tbl_import")
[code]....

I am developing a database and testing it with dummy data. With 50,000 records, the query process using SQL command is just OK. But if I double the total records, the query process takes longer time. The query is to make recapitulation using SUM of SQL command based on certain criteria. Any idea to make the query faster?
Thanks.

I have my database connected to a network of ten computers. I recently switched my linked tables from a Mapped Network Drive to using the actual UNC path \computerfolderdatabase.mdb
My users have started to notice it takes longer for the database to connect in order to log in. Once they have established the connection, the data transfer speed seems to be normal.
Is this to be expected? Any suggestions to speed things up for login? Or is this the downside to using UNC?

I have a pop up form with a datasheet as a sub form. We use the up and down arrows to move between records. The problem is using the down arrow is 4 to 5 times slower than using the up arrow. This becomes a big problem when we hold down the arrow to move down 50 or more records. I believe it has something to do with the way the screen is repainted because in testing if I shrink the datasheet to show only 3 or 4 records the up and down movement is almost identical and matches the performance of the excel spreadsheet that this form was based on. Is there any fix for this?

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.
Thanks in advance

I am trying to do the good 'ol sales report (query) to include customers with no sales.
I have a customers table, account number table, sales table & sales (line) detail table. (all linked in that order)
If I run a query to show customers (in the customer table) with account numbers, that works
An unmatched query to show customer without an account number works (but of course the unmatched account number field isn't shown).
How can I get the two two be shown together with the "unmatched" having a null or 0 for their account number?
I am guessing in principle, the resulting solution can be modified to show customers without sales alongside those with sales?

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?

Hello All,
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.
SELECT SalespersonID, Sum([SlsPrice]-[RtnPrice]-[SlsDiscnt]+[RtnDiscnt]) AS fldPrice FROM MyTable WHERE (((Source)='d') AND ((DistrictID)='01') AND ((CategoryID) = 'HCPROD') AND ((BrandID)<>'CSS')) AND (((BrandID)<>'1356')) AND (((BrandID)<>'1400')) AND (((BrandID)<>'1551')) AND (((BrandID)<>'555')) AND (((BrandID)<>'66'))

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.

I have a query where these are the fields:
ProductRevType
RevLag
RevFlowThru
CloseMoYr
ProjRevDate
CurrentMRC
ProjRevMRC
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 form which will be used as the basis to print a label.
It is bound to a query and when I open the form I pass over a 'where' condition to return 1 record. I then use the query to produce a report/label.
What I want to do is to update the form/query without updating the underlying tables to the query.

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;
Thanks for you time! :)

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.
Can someone see where I’m going wrong?

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:
WorkerID | DayID | HourID
----------+---------+--------
1 | 5 | 12
4 | 5 | 13
16 | 5 | 15
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:
WorkerID | DayID | HourID
----------+---------+--------
1 | 5 | 12
4 | 5 | 13
| | 14
16 | 5 | 15

I have a query with three sub queries, all returning a number from different tables. But when any one of the sub queries returns a blank, the entire main query is blank.
How do I stop this from happening? I have tried NZ() on the sub queries and on the main query, but the blank still happens.

I have a database which among other things records how jobs are received i.e.: Telephone, Email, Mail, Facsimile or Web.For each client I want to identify the percentages of each method of receipt against the total of jobs received and during different time periods.I have created a make table query for all jobs received between variable dates for a client entry of the name of the client and the start and finish dates are required to run the query.
I have a crosstab query set up to count each method of receipt and a final query to work out the percentages using the total from the crosstab query fields divided by the total of all methods.I have a macro set up to replace the table with new data when I want the stats for a different client between new dates, therefore the different methods of receipt may vary for the less active clients i.e.: they may only have telephone and email .
My problem is if I choose a client where we have not received a job by a particular method (say web or facsimile), the last query working out the percentages has fixed names to cover each method but naturally produces an error when it cannot find a corresponding method of receipt. I have experimented with NZ() without success.My question is can I either have preset standard names of the column field in a crosstab query? Alternatively in the query calculating the percentages, can I include code to ignore a non-existent field in the crosstab query.

Hi...
I have a query that when I run it normally (just click on it) then it runs fine. (It is a union query, getting it's data from 8 other queries (who has their dependancies)
But when I want to run a report from it, Access gives me an error saying "query is too complex".
I am flattered, but I would prefer access to work than say I write stuff that is too complex for it. :cool:
Any ideas?
I am confused by the fact that it runs when I double click the query, but the report bugs it out.

I am really stuck. I have spent two days searcinh different forums trying to solve my problem. I am trying to create an UPDATE q to my Access database. But I get either the: "Syntax error in query. Incomplete query clause" or "Syntax error in UPDATE query".
First of all here's the URL: www.innotec-as.no/login/Kunder
Login U/P either: "alfen" or "thomas".
The page opening up shows the user info, U/P and adress.
viewing the information is working perfectly - but editing it..no way.
When editing and submiting the data the above errors occour.
Try that and you'll also see the SQL I am trying to execute.
The CODE is as follows:
SQLtemp = "UPDATE 'Brukere' SET"
SQLtemp = SQLtemp & " 'navn' = '" & request("Navn") & "', "
SQLtemp = SQLtemp & " 'epst' = '" & request("Epst") & "', "
SQLtemp = SQLtemp & " 'Pass' = '" & request("Pass") & "', "
SQLtemp = SQLtemp & " 'Firma' = '" & request("Firma") & "', "
SQLtemp = SQLtemp & " 'BAdresse' = '" & request("BAdresse") & "', "
SQLtemp = SQLtemp & " 'BPostAdr' = '" & request("BPostAdr") & "', "
SQLtemp = SQLtemp & " 'PAdresse' = '" & request("PAdresse") & "', "
SQLtemp = SQLtemp & " 'PPostAdr' = '" & request("PPostAdr") & "', "
SQLtemp = SQLtemp & "WHERE 'Bnavn' = '" & request("Bnavn") & "'"
Response.Write(SQLtemp)
Response.End()
conn.Execute(SQLtemp)
rs.Update[/COLOR]
The finished SQL statement looks like this:
UPDATE 'Brukere' SET 'navn' = 'Alf Byman', 'epst' = 'alf@baccara.no', 'Pass' = 'alfen', 'Firma' = '', 'BAdresse' = '', 'BPostAdr' = '', 'PAdresse' = 'sdfg', 'PPostAdr' = '', WHERE 'Bnavn' = 'alfen'
I have tried to user single quotes, doubble quotes, brackets etc. nothing works.
The code I use for connection is as follows:
<!--#include file="../adovbs.inc"-->
<%
dim conn, rs, SQLtemp
' DSNless connection to Access Database
set conn = server.CreateObject ("ADODB.Connection")
rs="DRIVER={Microsoft Access Driver (*.mdb)}; "
rs=rs & "PWD=uralfjellet; DBQ=" & server.mappath("../../../../db/kunder.mdb")
conn.Open rs
I'll be very HAPPY for some expert help on this.

Hello, I have a combo box on a form which lists some names generated from a table.
I would like the selected name to be inputted into the 'critera' of another query called 'qryPBCustLevel' and for that query to be run.
I have tried to code this, but it is crashing at the point it trys to add the name into the query.
Can anyone help? Code listed below.
Sub cmbPB_AfterUpdate()
'Set the Dimensions of the Module
Dim strSQL As String, strOrder As String
Dim dbNm As Database
Dim qryDef As QueryDef
Set dbNm = CurrentDb()
'Constant Select statement for the Query definition
strSQL = "SELECT DISTINCT tblTempPB.PB_NAME" & _
"FROM tblTempPB"
strOrder = "tblTempPB.PB_NAME;"
' Find the record that matches the control.
Me.RecordsetClone.FindFirst "[PB_NAME] = '" & Me![cmbPB] & "'"
Me.Bookmark = Me.RecordsetClone.Bookmark
'Pass the QueryDef to the query
Set qryDef = dbNm.QueryDefs("qryPBCustLevel")
qryDef.SQL = strSQL & " " & strOrder
'Open the Query
DoCmd.OpenQuery "qryPBCustLevel", acViewNormal
End Sub
Thanks, Steve. :confused:

Here's my problem. I need to generate a report that says how much of each individual product was produced and as well as the total produced for a specified category in a time period. Something like the following:
05 Catagory A: 02 Product AA, 01 Product AB, 02 Product AC
10 Category B: 07 Product BA, 03 Product BB
04 Category C: 01 Product CA, 01 Product CB, 01 Product CC, 01 Product CD
etc...
I currently have a query that queries a database and pulls out all products that were produced in a specified period and the categories they belong to and dump them into a local access table. Now what I need to do is search through the query results and count up how many of each product were produced (02 AA, 01 AB, etc...) and the totals for each category. The number of categories is pretty limited (6), but there are hundreds of product codes, so I need a way to do this without having to type in each induvidual product code as the requirement by which the query searches. Also, the product codes that get returned are different every day.
I was thinking something along the lines of take the product code of the first row and check for any others in the results that match and write that into another table. Then move onto row 2 and use its product code as a search parameter and search through the query results for any matches. Then continue that until the end of the query results. Can I do that? Is there a better way to achieve what I need?

Been working on this for a while now and can't get it to work how I'd like after trying a few things.
I have a form ("Production Form") from where users input start and end times for various processes against a particular product. Currently, I have (or had) a query (and linked report) "ProductionDurations" where durations for each of the processes were calculated for different product runs.
I have since tried to adapt this query to include reference values contained in another query ("ProductionDurationsPerBulkLitre", based on a "Products" table) for how long each process should take for each production, by multiplying by the volume processed. Here's what I have at the moment in the "ProductionDurations" query:
Quote:
SELECT DateDiff("n",[BlendlineCIPStartTime],[BlendlineCIPEndTime]) AS BlendlineCIPDuration,
DateDiff("n",[FlavourMixStartTime],[FlavourMixEndTime]) AS FlavourMixDuration,
DateDiff("n",[BlendlineStartTime],[BlendlineEndTime]) AS BlendlineDuration,
[Code] ....
Rather than returning what I require, the above bolded part is returning a calculated value for each production against each of the products. What I require is a calculated value for each production against the product that has been selected on the form.

First query = Sum Products:
Code:
SELECT Sum(Tab1.Inputs) AS SumOfInputs, Sum(Tab1.ValInp) AS SumOfValInp, Sum(Tab1.Outputs) AS SumOfOutputs, Sum(Tab1.ValOut) AS SumOfValOut, Products.Product, Products.VAT, Products.UM
FROM Tab1 INNER JOIN Produse ON Tab1.ProductID = Products.ProductID
GROUP BY Products.Product, Products.VAT, Product.UM, Tab1.ProductID;
Second query :
Code:
SELECT Nz([SumOfInputs],0)-Nz([SumOfOutputs],0) AS Stoc, Nz([SumOfValInp],0)-Nz([SumOfValOut],0) AS ValStoc, IIf([Stoc]=0,0,([ValStoc]/[Stoc])) AS CMP, [Sum Products].Product, [Sum Products].SumOfInputs, [Sum Products].SumOfOutputs, [Sum Products].SumOfValInp, [Sum Products].SumOfValOut, [Sum Products].VAT, [Sum Products].UM
FROM [Sum Products]
GROUP BY [Sum Products].Product, [Sum Products].SumOfInputs, [Sum Products].SumOfOutputs, [Sum Products].SumOfValInp, [Sum Products].SumOfValOut, [Sum Products].VAT, [Sum Products].UM
HAVING (((Nz([SumOfInputs],0)-Nz([SumOfOutputs],0))>0.09 Or (Nz([SumOfInputs],0)-Nz([SumOfOutputs],0))<-0.09));
I need to combine those two query sql code to make only one query.
