Querying Massive DB

Apr 5, 2006

I need to select the last 20 records from a databse that have over 1.25 MILLION records.

Obviously the usual stuff like order by is breaking the server with buffer issues.

Anybody any ideas of how to get around this?

Linking Massive Amounts Of Files

Jun 10, 2005

Hi, it's me again, the guy who works with the Amusement ride industry. I'm trying to set up a way to ogranize all our saftey bulletins that we get.

I've already looked into indexing but the major problem is that the user will need to be able to search on multiple criteria (for example the Tilt A Whirl was made by three different manufacturers). Also I can't download that nifty google tool bar because we're running win 2000 without service pac 3.

Access seemed like a great alernative, but I have about 300 or so files I need to link. Is there a faster way of linking these files than going through and doing them one by one?

I have a pre-made index the guy before me made in exel. Most all the files are in PDF format if it helps at all.
Thanks.

Second Normal Form A Massive Table

Apr 4, 2007

Hi, i'm new here and I know there's a lot going on but i was hoping someone could point me in the right direction or give me a few tips...

I've imported a very large (nearly 15000 records) set of data into an Access database as one big huge table storing various bits of information about coins. As far as I can tell, the data is in at least first normal form, in that no multiple values are stored in any columns (not yet sure of the technical term - field?)

Anyway, I've managed to use a make table query to separate out some of the content of the table into separate tables with relating entities.

One question is, and please bear with me - How do I add an autonumbered primary key to these newly separated out tables and then add these autonumbered items to the original tables as IDs so that I can set up relationships? Is there a "proper" way to go about describing this?

The following consists of ALL the fields in the original table and how i've split them up by table:

STOCK
Group
ItemNo
ListNo
TypeCode
ActualDate
SortDate
CostPrice
SalePrice
Estimate
StockLevel
DateEntered
DateSold
Archived
Ref1
Ref2
Picture
Description
Cats
DenomCode
TypeCode
PeriodCode
ArchiveWhenSold
NotForSale
KeepSold
StockItem
Highlight
OnLists
OnWeb
Proof

DENOMINATIONS
DenomName
DenomCode
DenomHeading
DenomValue

PERIODS
PeriodName
PeriodCode
PeriodHeading
PeriodStartYear
PeriodEndYear

VARIETIES
Variety

The Variety field in the Variety table is especially problematic. There were 1259 varieties stored in the original table which are now in a separate Varieties table which is great. But how do i now add an autoincrement number and call it, say, VarietyID, but then link each Variety back to the main list of coins but replace the full Variety description with the newly created VarietyID?

If any of that made sense, i'd REALLY appreciate some wisdom here.

Thanks

Access Massive Data Lookup

Sep 16, 2014

I have created a database with a list of product codes, pricing, costs, and supplier name. Now I have about 100 product codes which I would like to look up for all those information. Is there an effective way to do it in Access? I know I could export the whole datasheet to Excel to do a vLookup, but it may be lots of waiting time if the data are massive.

Disable Filter Functionality / Massive Slowdowns

Oct 28, 2005

Is there a way to disable the filter feature in MS Access? I have several users that use the filter to find a single record when I've repeatedly told them that using CTRL-F is faster and less of a strain on network traffic.

I'm trying to eliminate all possible causes of a massive slowdown that occurs everyday at roughly 10-noon. There are several ODBC timeouts (even after including some code to have it attempt to retrieve the data 3 times prior to it allowing the timeout message to pop-up).

I have removed all linked tables/queries that are not needed and the database has been rebuilt. Compressed the database is under 2 megs and the SQL Server backend is on it's own server where the same queries return instant results.

SUM Querying

May 15, 2006

Hi I'm having a bit of a problem with the sql query below


SELECT [Table 1 Personal Details].Surname, Sum([Table 3 Daily Activity].[Public Holiday]) AS [SumOfPublic Holiday], [Table 3 Daily Activity].[Week Commencing], Sum([Table 3 Daily Activity].[Authorised Absence]) AS [SumOfAuthorised Absence], Sum([Table 3 Daily Activity].Holiday) AS SumOfHoliday, Sum([Table 3 Daily Activity].Sickness) AS SumOfSickness, Sum([Table 3 Daily Activity].[Unauthorised Absence]) AS [SumOfUnauthorised Absence], Sum([Table 3 Daily Activity].[Hours Per Week]) AS [SumOfHours Per Week], [Table 9 Funding].Project
FROM [Table 1 Personal Details] INNER JOIN ([Table 3 Daily Activity] INNER JOIN [Table 9 Funding] ON [Table 3 Daily Activity].[ID Number] = [Table 9 Funding].[ID Number]) ON [Table 1 Personal Details].[ID Number] = [Table 3 Daily Activity].[ID Number]
GROUP BY [Table 1 Personal Details].Surname, [Table 3 Daily Activity].[Week Commencing], [Table 9 Funding].Project
HAVING ((([Table 3 Daily Activity].[Week Commencing]) Between [Enter Start Date] And [Enter End Date]) AND (([Table 9 Funding].Project)="NETWORKS"))
ORDER BY [Table 3 Daily Activity].[Week Commencing];


My problem is that the Surname is displaying for each record.. what I mean is that I want the surname to be grouped so that I get the SUMofHours summed correctly?

here's an example of what I'm getting

SURNAME, WEEK COMMENCING, SUM OF HOURS, PROJECT

Brown,13/02/2006,35,NETWORKS
Brown,20/02/2006,35,NETWORKS
Malcolm,13/02/2006,35,NETWORKS
Malcolm,20/02/2006,35,NETWORKS



Here's what I'm really looking for though

Brown,13/02/2006,70,NETWORKS
Malcolm,13/02/2006,70,NETWORKS


I need the Hours SUMMED with no replication of surname.

Thanks

Querying An Old Database

Jun 29, 2006

Hey all,

Here is my problem, im working on an old 97 database that is being used by a program and sometimes errors occur through the use of the program and certain tables are not updated properly, so instead of doing this manually I want to be able to query this database through SQL and then later down the line put these SQL queries into a program so it will be more user friendly to edit the database.

So when I try and test one of my queries out, access tells me that I cant make changes to the database because it was created in an earlier version. Now I know i can update the database, but if I were to do that the program that is using the database wont work!

So im a little stuck now, will I have to keep editing the database the manual way or is there another option here? Im wondering (for any java heads out there) If I were to write a java program that would query the database and edit the data inside would that work or would I get back an error?

Thanks in advance!

Querying Issues

Jun 16, 2005

Ok, I have a DB of client contacts. I'm drawing the values for a query from a form using [Forms]![Sort]![Contact] in criteria and using the parameter field to give values to each. The query works fine for state, contact and industry- all in conjunction with each other. Where I am having problems is:

1) When I input less then all 3 working parameter values in the referenced form the query will not run. I think i need an SQL string of some sort- doing an if, then relationship, but I don't know how to do this.

2) I don't just have 3 values I want to reference, I have 9 total. On the form one of the problems is that a field is chosen by the end-user using check boxes (allowing only one check between three values, with no default: current client, potential client, not applicable are the choices). However, in the table these are referenced by the values of 1, 2 or 3. Another of my fields is check boxes, but referenced by yes, no. How do I correspond the field values in text to numerical values in the table? (and the yes/no prbly the same I will assume)

3) I have "sectors" as a field option in my Sort form (again the drop down menu to select). There is one field for the choice, however, in my data table I have 4 fields corresponding all back to that one field in the form through the query. This doesn't seem to work at all. The sector choices, in my original Input form, are 8, chosen and recorded into the table using 4 consecutive drop downs. They are the same 8, so sometimes a sector like Agriculture could end up in the Sector 1, or Sector 2, etc field in the table. Some can also be left blank. So in summary of this dilemma: 4 drop downs in input form to 4 data table fields, all being queried through one field on the Sort form, which is tied to my query through a command button, having specific criteria reference text in the form.

Thanks in advance for any help!!!

Querying Using Value From A Subform

Nov 4, 2005

I need to take a value from a subform and use it in a query but I don't seem to be able to come up with the correct criteria in the query....

I have so far tried:
[Forms].[frm_Matching].[SubMatching].[txtSingleFixedPayer]
[Forms].[frm_Matching].[SubMatching].[form].[txtSingleFixedPayer]

[Forms].[sub_Matching_single].[txtSingleFixedPayer]
[Forms].[sub_Matching_single].[form].[txtSingleFixedPayer]

[Forms].[frm_matching].[sub_matching_single].[txtsinglefixedpayer]
[Forms].[frm_matching].[sub_matching_single].[Form].[txtsinglefixedpayer]

And probably a load of other versions of the above.... can anyone help out possibly?

The following pulls back the value in code but isn't accepted in the query as a valid criteria:

Forms("frm_Matching").[SubMatching].[Form].[txtSingleFixedPayer]

Anti-querying?

Jun 2, 2006

OK,
I work for a political party. I work with voter history information. Normally, I am doing queries in order to bring up particular voters, and eliminate others.

Example - the basic table I work with contains the names, addresses, affilitations, and voting histories of everyone in my county. I normally query to bring up voters of a particular party, or people who voted in a particular election or number of elections or both. I more or less sort voters out, but in a positive manner, by creating tables with voters who did a particular thing.

For example: out of all the voters, I just want Democrats who voted in two of the past three primaries. I would then get a table that contained just those voters and no others.

Today, though, I was asked to create a table that would exclude voters based on their behavior, exluding voters who did a particular thing but showing everyone else.

Example, I have a request for all of the voters in the county, except those who voted in the 2004 and 2002 primaries. I know how to create a table with those voters and no others, but I don't know how to query for everyone but those voters. Can anyone help?

Querying On MONTH Alone!

Sep 18, 2006

Hi there,

I am getting really wound up with this. It should be so simple!

I need to create a query on a field (actualdateofvisit) and group it by the month to give me a count of all those visits (hence the catchy field name) which occurred each month since the beginning of the project. In other words I want to see:

Month Count of Visit
Jan 43
Feb 54
Mar 78

and so on.

I have tried everything I can think of but cannot work out how to do this? I need to do it in a query NOT a report as I want to port it to Crystal reports to display there.

I am think of something like:

field: Actual Date of vist
table: visits
total: Group By
Criteria: "Month"

Can anyone help me?

Thanks and Regards
Mark

Querying Several Criteria

Mar 13, 2007

I hope someone can help with this query I am having difficulty with. The table I am querying has several expiration dates and Yes/No Fields
Listed below is what I need and the query needs to return the name and data if only one or all of the following applies

Name
"A Date" is before today
"B Date" is before today
"C Date" is before today
"D Date" is before today
"A Yes/No" = No
"B Yes/No" = No
"C Yes/No" = No

In other words, if all dates are = to today or later and Yes/No Fields are = Yes - I don't need them in the results.

I have tried this several ways using AND and OR but either way my results are ALL the records. not just the records that meet any or all of the above criteria. Maybe it's too much to ask? :o)

Thanks in advance for your help.

Querying Fields With Zeros

Jun 20, 2006

I have a database where the primary key is a field for pass numbers. Many of the pass numbers begin with zeros (example: 0023456). I changed the table property for the pass numbers to text so the zeros would be recognized. However, I have a form based on a query to search this pass number field. How can I get the query to recognize the pass numbers that begin with zeros. When I put in any other number above zero, the pass number satisfies the query and the employee information pops up. Aside from AllowZeroLength and trying to format the text field, I cannot get the query to recognize the pass numbers that begin with zero. Please help:eek:

Querying Duplicate Fields

Jul 14, 2005

Please can anybody help.
I wanted to have a form containing a list of members forenames and surnames in one record. I wanted to be able to input the members reference number and then the forename and surname would be automatically filled in.
I have achieved this through a query based on a table with ten foreign keys for the members. The query uses the members table ten times to join the ten foreign keys.
This works fine and the form runs with space for ten members and I can enter a members reference number in each field and their forenames and surnames are filled in.
The problem is that I wish to run queries with members surnames as criteria to bring out all records containing those members. How can this be done without having to set the criteria in the query in each of the members surname fields.

I know I can do this if I have a separate record for each member in the form
but I really need ten members in each record.
I hope this makes sense and somebody can help.

Thanks in advance
John

Querying From Tables Without Same Fields

Aug 11, 2005

I am new to this forum and a beginner to intermediate with Access.

I was given a database that has 3 tables with data on the capture of alligators. One from 1998-2000, one from 2001-2003 and one from 2003-present. Each of these tables has different field names because they were created by different people on different projects. I need to combine the three tables into one that pulls such data as "date", "time", "size" etc. I don't need all of the fields from all of the tables just select ones and some of the tables do not have the information that I'd need in the final table. I've read through append, update, and make-table queries and am not sure if I can even solve this problem with a query. The error messages I get refer to null values or if I do get a table it has 14000 records, which is way more than the actual number of records.

Thanks for any ideas

Beginner's Question About Querying

Oct 18, 2005

I apologize in advance if this question is completely obtuse, but I'll pose it to the group nonetheless.

My task is to analyze accruals versus actuals for the past quarter (i.e., July-September). What is of particular interest are the variances between the accrued and actual amounts. I have several fields of data, but the common field is Shipping Unit (SU). My initial plan is to upload the tables with the accrued and actual records separately and query SU's to pull in all instances in which there are matching accrued and actual SU's. This is where it gets a bit fuzzy for me. I would export the resulting queries into Excel, unless there is a means to produce the analysis directly from Access.

I haven't used Access in ages, so I don't recall how I might best proceed. Please advise with your thoughts. :confused:

Help With Input Box Based Querying

Nov 22, 2005

I have two linked tables as follows:

Table 1

Main Service ID (primary key)
Main Service

Table 2

Sub Service ID (primary key)
Sub Service
Main Service ID (foreign key)

one-to-many relationship

I would like to query the tables, so you search on the Sub Service and it returns all of the Main Services it come under. I would like this query to run off an Input Box that will allow me to type in the Sub Service or a word.

I have managed to get the Input Box, by putting the following code into the criteria :InputBox («prompt», «title», «default», «xpos», «ypos»). But when I type something in the search fails. I have chopped and changed the fields I search on, but can't get it quite right.

Can anyone help me on what fields to choose and what I need to set in the criteria to get the search running properly from the input box?

Also is there any way to program Access or VB to return the results in a message box e.g. **** is a Sub Service of ***** - listing all main services it appears under?

Any help is most appreciated,

Thanks,

Luke

Querying, Then Reversing The Query..

May 9, 2006

OK, coming up with a title for this one was a little difficult. Almost as difficult as the problem I'm facing ;)

Here's the basic premise. The database is used to register people for a weekend convention. Part of the registration allows the person to request a specific roommate. In an ideal world, this would be relatively simple--match the roommate to the person, and you're done!

Did I mention they're teenagers?

Here's what happens. In all of the following examples, you are given only the ID number of a person to start with (because referencing any column but the bound one in a combo box from a query seems impossible, despite what Microsoft has to say (http://office.microsoft.com/en-us/assistance/HA011730581033.aspx)), and must dump all relevant names and ID's into a temp table.
Example 1:

IDFirstLastRFirstRLast
1MattBrownLukeWilson
5LukeWilsonMattBrown
9PhilHeartMattBrown

In this case, we have two people that have requested Matt Brown as their roommate. Based solely on the ID Number of any given person above I need to dump all three names into a temp table to be displayed to the user, so he can pick who will go where. Physically, the first two people would be roomed together, and the 3rd would be roomed in a single room nearby.

Example 2

IDFirstLastRFirstRLast
1MattBrownLukeWilson
5LukeWilsonMattBrown
9PhilHeartMattBrown
72CraigJohnsonPhilHeart

Similar to the last, but we've added a fourth person that has requested the 3rd person. Doing it the manul way, we'd room the first two together, and the last two together, in rooms next to each other. Unfortunately, we may not find the last two until we're two floors away, and end up having to shuffle people all over the place to get it to work. Now, we could be jerks, and just say, 'sorry, you screwed up, your problem, not ours'...except facing a crying 14-year-old girl upset because she's not with her friends isn't exactly fun. This is why I want to find all four people immediately after rooming any one of the above.

Example 3:
IDFirstLastRFirstRLast
1MattBrownLukeWilson
5LukeWilsonPhilHeart
9PhilHeartCraigJohnson
72CraigJohnsonMattBrown

Ah, the circle of life. Person 1 requests person 2, person 2 requests person 3, 3 request 4, 4 requests 1. This is surprisingly common. And annoying. Physical results would be the same as the previous example.

So to summarize, I start with person 1. Add him to the temp table. Then find the person he requested as a roommate. Add him to the table. Then look at the roommate's requested roommate, compare it to the temp table. If the person is there (ie, a direct match), then stop. If he isn't there, then query the database. Not there? Stop. Found another hit? Add him to the table. Search again. Then, display them all in a list box allowing the user to pick and choose who goes where.

I don't hope to automate the whole thing. That's not the goal. There are a variety of other factors that go into rooming that could never be automated, and require a personal touch. All I want to do is make it easier to find duplicates to streamline the existing manual procedure.

Now, how do I do it?
