Need Help Optimizing Query
Sep 13, 2006Currently, I have the following query being run against a table holding what is essentially an access log for a rather elaborate system. I have been doing lookups against the log to determine last changed and created dates/times. The log has grown large enough that the lookups I am doing are taking too much time to perform. Is there any way to get at the data I want faster, barring adding created/modified fields to the individual records in every table, and storing the data there as well?
Here is the current query:
SELECT Min(SecurityLog.Date) as Created, Max(SecurityLog.Date) as Modified FROM SecurityLog, WorkOrderLineItems WHERE (Len(SecurityLog.Param2) <= 4) AND (WorkOrderLineItems.PONumber = '" & PONumber & "') AND CStr(SecurityLog.Param1) = CStr(WorkOrderLineItems.WorkOrderNo) AND CStr(SecurityLog.Param2) = CStr(WorkOrderLineItems.LineNumber);
Param1 and Param2 are Memo fields, Whereas WorkOrderNo and LineNumber are numeirc field, to explain the funny type conversion.
This was good enough for a long time, but as the SecurityLog table is reaching a quarter million entries, it's starting to cause some problems.
Optimizing 'List Control'
Sep 11, 2006Hi,
Does anyone know if it's possible to make the column heads, column count, column width properties of a list box fit automatically according to the text they hold?
Any help will be very much appreciated.

Optimizing MS Access 2007 Over VPN
Apr 24, 2007Hello, I am new here and needed a little help if you wouldn't mind.
I've built an application for a company that I also use for other work I do for them. I have several tables, queries, forms, and a few reports. I have a lot of VBA code behind the scenes. The application is about 6 mbs. When accessing it over the VPN the application runs really, really slow. I need to find a way to increase the speed of the application so that everyone can work in it without the huge delays. Obviously, it runs normally locally.
Modules & VBA :: Optimizing Tree View Of Large Database
Oct 24, 2014I have a form with a Treeview in. I have it populated from a self-referencing database using the following code.
Code:
Private Sub Form_Load()
Const strTableQueryName = "SELECT * FROM tblHierarchy ORDER BY tblHierarchy.Function_Parent;"
Dim db As DAO.Database, rst As DAO.Recordset
Set db = CurrentDb
Set rst = db.OpenRecordset(strTableQueryName, dbOpenDynaset, dbReadOnly)
[Code] ....
The database this is referencing is about 30000 lines and it takes ~4 minutes to populate this way. I know Treeview isn't really supposed to be used in this way however it's what is required.
Now I have come up with the theory that I will populate each node with children as its clicked to be expanded.
Uploaded my current treeview example ....
Queries :: Unable To Open Or Design Queries From Older Access Files
Jan 1, 2014Im trying to work on an db in Access 2007 that was migrated from Access 2003 (in fact its been migrated several times starting from Access 97). It executes and runs with no problems in both versions.
The problem is when trying to open some queries (not all) - Access is unable to open the query in design mode and gives me this error :
" is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long.
However, as I cant open it - I cant check it. Im pretty sure none of the fields have invalid characters (they do have spaces) and Im not sure how long is too long....
Queries :: Running Multiple Queries To 1 Excel File With Different Tabs For Each Query
Jul 18, 2013I'm using Access 2003 and excel 2003.
We currently manually run 5 different queries then copy and paste this data into 5 separate tabs on 1 workbook, I'm trying to automate some of this process if possible.
I am trying to use the 'transferspreadsheet' action within a macro to run a query and post it into a template excel file, using this code:
Trasfer Type Export
Spreadsheet Type Excel 8-10
Table Name (query Name)
FIle Name (FIle location)
Has field names No
Range Blank
----
This does seem to work and puts the data on a new tab on the specified workbook.
However I have a few questions:
1. Can you specify which query gets put onto which tab in excel? The tabs have different fixed names.
2. Can you specify which Cell the data gets pasted into to? As each tab has a set of headers and titles which need to remain.i.e would need to get query 1 to start in cell A4.
3. How would you expand the above out so that it runs all 5 queries, would you just add in multiple transfer spreadsheet actions in the same macro?
Queries :: Method For Combining Crosstab Queries With Same Criteria From Multiple Fields?
Dec 2, 2014I have 3 cross tab queries that are completely identical with the exception of the field that they pivot. Each field is searching for the same values just in different columns, with the end goal being to get the sum of the values for each pivoted column. I'm wondering rather than having 3 almost identical queries is there a way to use a crosstab to sum the values from each of the three fields rather that having 3 queries which then have to be aggregated in a fourth?
QUERY1
Code:
TRANSFORM
IIf(Count(PT_LEVEL.UNIT) Is Null,0,Count(PT_LEVEL.UNIT)) AS CountOfUNIT
SELECT
PT_LEVEL.INF_YEAR,
PT_LEVEL.INF_MONTH,
PT_LEVEL.UNIT
[code]...
Queries :: Crosstab Queries - Export Command Ask To Enter Date Parameter Twice
Feb 24, 2015I have a crosstab queries which uses the date query parameters. However, when I go to my Export command (code is below), it ask me to enter the date parameters (start date and end date) twice. What do I have to do so that the system will ask me to enter once only?
Code:
On Error GoTo Err_cmdTest_Click
'Must 1st set a Reference to the Microsoft Office XX.X Object Library
Dim dlgOpen As FileDialog
Dim strExportPath As String
Const conOBJECT_TO_EXPORT As String = "qryEXPORT"

Queries :: Joining 3 Queries And Displaying Results In Separate Columns
Jul 31, 2013I have 3 queries named Mech Final Equipment 3 Mth, Mech Final Equipment 6 Mth, and Mech Historical Final Equipment.They all have two fields-Final equipment and Sum of Sum of Down (calculating the number of minutes each piece of equipment was down in the time period selected).
My ultimate goal is to join the three queries to display a pivot chart that uses the Final Equipment as the category field and 3 Mth, 6Mth, and Historical as seperate data fields.What I have is a join query (Which I have named Mech Final Equipment H63 Joined)
Using this SQL:
Code:
SELECT DISTINCTROW [Mech Final Equipment 3 Mth].[Final Equipment], Sum([Mech Final Equipment 3 Mth].[Sum Of Down]) AS Duration
FROM [Mech Final Equipment 3 Mth]
GROUP BY [Mech Final Equipment 3 Mth].[Final Equipment]
UNION
[code]...
Which returns a table that looks like this:
Final Equipment, Duration
Ancillary Equipment, 225
Ancillary Equipment, 401
Ancillary Equipment, 1787
Brush Unit , 1252
Brush Unit , 2519
Brush Unit , 8004
And so on.What I need the table to look like is this
Final Equipment, 3 Mth, 6 Mth, Historical
Ancillary Equipment, 225, 401, 1787
Brush Unit, 1252, 2519, 8004
And so on, like a cross tab.I tried to do a crosstab query but I don't have enough fields.
Queries :: MS Access 2010 - Export Queries Into One Workbook But Different Worksheet

Queries :: Adding Calculations To Queries Based On Columns In Query
Feb 18, 2014I am trying to add calculations to queries based on columns in the query... it seems to randomly expect 'Expression' or 'Group by' as column types, and Im having to create 3 sets of queries following on from each other to de-dupe data and allow filters on calculated values.
Also I've got a function which turns a date into a quarterly cohort, e.g. Oct 2013 -> 20134. I use ot on a lot of dates. I created a VBA function, CohortQ used as follows in queries:
Cohort: IIf Year([InputDate]) < 1990 or Year([InputDate]) > 2020, 0 CohortQ([InputDate]))
In the VBA, InputDate is defined as a date
Code:
Function CohortQ(InputDate As Date) As Integer
If InputDate = 0 Then
CohortQ = 0
Exit Function
End If
[Code] .....
But when I run it on a date field, it gives me a data mismatch error. I can't step through as it's working on 600K rows.
If I put the function into the query,
Cohort: IIf Year([InputDate]) < 1990 or Year([InputDate]) > 2020, 0 Year([InputDate])*10+DatePart("q",[InputDate]))
it works.
Queries :: Access 2007 / 2010 - Combining Two Queries Into One?
Jan 24, 2014I have two queries, one base upon the other. I would like to combine them (If Possible) into one query so I can embed them into a form or report. I have tried without success at finding the answer on the forum as well as searching the web.
The table lists employee numbers and dates they worked. I need a count of how many employees worked each year, based upon the paycheck date, not the actual date worked. Pay check dates are two weeks apart. An extreme example, is the first pay check date of 2010 was on 1/1/2010, but all the days worked were in 2009, this would have to be included in 2010 not 2009(See the query for further date calculation understanding). Anyway, the date calculations are not the issue here.
I only have one table, so if I am not mistaken, I can't use the WHERE (SELECT... JOIN) feature. I also was unsuccessful at using SQL DISTINCT.
I am running ACCESS 2010 Tables are ACCESS 2007.
OS is Windows 7 Ultimate.
I have included a same database with the queries. qryEmployeesAnually2 is the results I am trying to achieve.
Queries :: Calculated Field - Top 50 Queries Setting Not Working
Sep 24, 2013I have a query which returns a calculated percent. I have ordered that in descending order, and now want to see the top 50. So (In Access 2010) I entered 50 into 'Return'. But it returns all of the records!
Is this because pct is a calculated field? How can I correct this? The SQL seems to be correct.
Code:
SELECT TOP 50 HeciFail1.POHECI, HeciFail1.POQTY, HeciFail1.FAILQTY, IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) AS PCT
FROM HeciFail1
ORDER BY IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) DESC;

Queries :: Combining Data Results From Multiple Queries
Sep 30, 2014I am working on a report that has some special characteristics.
Let's say I have a list of groups of Vendors in a table, complete with VendorID. I have 3 other tables that use the VendorID: Complaints, Complements, and Terminations.
Each of these tables has a date that the Complaint, Complement, and Termination notice was received.
Every Fiscal Quarter, a report is pulled that looks back over the 4 preceding quarters to determine if a 5% threshold has been crossed by any of the vendor-groups in regards to the amount of Complaints they received.
The equation used for that is : (complaints/vendors_in_group)*100
It is imperative that the information has the current fiscal year and fiscal month (which I am tracking with functions from MS website), and I need to be able to store the information attached to the fiscal year and month.So when a user goes to the form and inputs the desired Fiscal Year and Fiscal Month, the database can display the 4 previous quarters of information...split into Q1, Q2, Q3, and Q4.
What I would like to have happen is to be able to have one table where the information is stored, quarterly, so that it can be retrieved for the report.
Questions:
1. Is it possible to have one line, per VendorID, that has the total number of Complements, Complaints, and Terminations, as well as the threshold percent stored in a table? Right now, I am getting LOTS of duplicates and blank lines when I try to put them all together. It has the right data, but takes about 10 rows per VendorID.
2. It is very important that the total number of Vendors in a group be captured on that quarterly report, so maintaining that number, in the same table, is essential and must be tied to the VendorID.
3. I have looked at Union Queries and Crosstabs, but I just dont know enough about them to make it work.
Queries :: Combine Two Queries Result Of Second Query In Another Column
Mar 15, 2014i I have two queries.. What i'm hoping is to combine the result into one query but not in one column only but instead the result of the second query should be beside the first query.. The result of the second query should be added as a new column.
First Query
SELECT tbl_uSers.UserName, Count(tbl_rEceived_eMail.EntryID) AS eMailReceived
FROM tbl_rEceived_eMail INNER JOIN tbl_uSers ON tbl_rEceived_eMail.UseriD = tbl_uSers.UseriD
GROUP BY tbl_uSers.UserName;
Second Query
SELECT tbl_uSers.UserName, Count(tbl_rEceived_eMail.EntryID) AS eMailProcessed
FROM tbl_rEceived_eMail INNER JOIN tbl_uSers ON tbl_rEceived_eMail.UseriD = tbl_uSers.UseriD
GROUP BY tbl_uSers.UserName, tbl_rEceived_eMail.ProcessedYN
HAVING (((tbl_rEceived_eMail.ProcessedYN)="Y"));
Queries :: Creating A List Based On Multiple Queries
Jun 23, 2015I have 3 select queries which Im trying to output to a combo - Ive tried a UNION query but I get an error
ODBC-- call failed ODBC Driver SQLBase.....
Firstly is do the results need to match within a union query? I mean they have no relationship what so ever Im just trying to populate this combo with the same results.
Secondly is there a better way to do it? 2 of the select queries query a linked SQL table and the third is a local table. All of the select queries work on their own.
Queries :: Access Multiple Queries Run With Date Parameter
Jun 19, 2015I have 5 queries that I am running. The first query has the date range parameters set in the field area that I need to run and each additional create table query is based off the results of the previous query.
1. Which is better to use to run all of the queries in one simple step? A macro or a form? I am exporting the final table to excel so that I can make some additional adjustments off of it.
2. How would I setup the date range parameters for the first query if I were to use a macro without going into the query itself and updating the date field? I tried setting up a macro to run the queries by using the OpenQuery action for each of the 5 queries, but I cannot figure out how to do the date range.
Queries :: Report Or Macro To Run Multiple Queries Using Same Parameters?
Aug 9, 2013So I run cash flow for a business, and we export data from Oracle and insert it into an access database. I have to run about 25 queries, entering in the same parameters for each. We number each week of the year. So for say the first week in January, I would run the first query and it asks: Beginning Week, I enter in 1, then another paramter value asks me the ending week. I have to enter in these parameters for each of the 25 or so queries, and it becomes quite irritating. Each query has a number of columns, but I am only interested in obtaining the sum of one of the columns, titled Distribution amount. So I am looking for something that will run each of my specified queries, then spit out the total of the distribution column for each in a table like.
Query 1: Total Distribution
Query 2: Total Distribution
etc....
Is there anything that would allow me to do this, with entering in the week parameter once, say week 1 start, week 1 end. and it use those same parameters for each query?
Queries :: Quotations Database - Queries Showing Too Many Records
Jun 25, 2015I have a database that is used to create Quotations. After all of the information is entered the queries that hold the calculations must be run. I have lots of calculated that rely on other calculated fields. When I need to Sum all of the calculated fields in one field I must create a new query. I currently have a QuotationID, PartID, and MetalID all linked together. The first of the calculations are done per Metal, and these are working fine. I run into a problem when the calculations need to be done by part. My Queries are creating a record for every Metal and this is throwing all of my numbers off.
View 1 Replies View RelatedUpdate Queries Vs Append Queries, Indexes?
Aug 7, 2007This is a very simple problem most likely for the masses, but I am new to access. I have employees who enter will enter information about specific tests on electronics components into separate tables by a form. I know my method is poor, but this is how it works. I got assigned this database at my internship this summer because they ran out of thigns for me to do.....I've never even used access before, so as long as it works, they're happy. I have a form which which writes to a first table with 20 fields. I then have separate update queries which take the data in the first table and put it in all the other tables. Trust me, i know this is pretty much the opposite of the whole point of a relational database, but I am and was limited by time, for the size of the database they want, there was no time to learn about normalization etc etc. Sorry this is wordy, but THE QUESTION is......if they run multiple tests wtih the same information for some of the fields I have fields named "Run#, Unit#, Date" etc, even if there is records wtih the same information, hwo do i get it all to show. Right now, it seems to be rewriting over the same records. If they run 3 tests on unit 10 on August 1st, how do i get it so all those show up. I think its somethign wtih in the table, for the primary keys, changing the Index: No, Yes(Duplicates) Yes(No Duplicates) but I could be way off. Thanks, if the question doesnt make sense i'll try to rephrase it, I apologize I'm running on about 45 min of sleep:confused:

View 11 Replies View RelatedQueries :: Identify Missing Records Between Queries
Jul 14, 2015I have a query that will draw down student details who have completed a course in a given month (May for example), i would like to use this data to identify those learners who are not enrolled on a course in the next Month (June for example). There is no field that denotes whether a student has left only that a course assosciated with their ID has a completion date within that Month. There are approx 250 records.
In my head it should work something like this
1) Identify all learners who finsihed a course in May (Identify learner ID, must have a course end date in that month)
2)Cross reference these against all those who started a course in June and identify the students that have completed in May but did not start a course in June.
Is it possible to store all those who completed (May) in a table/query and cross reference those who started in June and identify of the May completions who did not start in June?
