Access :: Data Import Challenge

Data Challenge

Jul 14, 2006

Dear All,

I currently receive MS excel files with forty columns and 7000 rows of data. I Perform a sense check and then convert the file to csv for loading into another system.

I've had a request to start performing this task for files of up to 13 million rows. Obviouslt MS excel will not be capable of doing this.

Can anyone tell me what MS product I should use? Access, foxpro? or do I need a non MS product and if so which one?

Many thanks

Wayne

Setting Data Import To Overwrite Data On An Existing Table

Aug 1, 2007

I have a database that I import data from an excel spreadsheet into multiple times daily. The table that this data is imported into has several key fields that if the data already exisits in the table, and I attempt to import data that is the same except for one or more of the key fields is different. At this time the database it creates a different record. I am trying to get the database to overwrite the data in the database.

Import Data From Excel Monthly - Not Manual Input All Data?

Jan 5, 2015

I was assigned by my manager to design an Access database system that is able to import all data from excel file monthly and creating charts & tables to analysis how each sales people and industry perform.

We originally have a big excel master sheet that has more than 10 sheets. I tried to import the current excel into access, but then i realized that this is not gonna work. because for next month, there will be new data and I can't do the whole import process over and over. Plus, after this system is designed, the users will be someone who has no knowledge in access, so i need to create a user-friendly system for them to use.

My questions is:since the data is always cumulative number, if I imported current excel file into access, when the next month comes, how to update the new data into excel. p.s. EXP. Mike's sale volume is different each month, and with the access system, for that column, it will be a cumulative number, like the total from the month of November to this month. how do i achieve this kind of update/import goal?I tried to link the excel to access, but by doing that, I will not be able to set relationship or change the attributes of any data type in access.

A Challenge To Say The Least

Dec 5, 2005

Here is a challenge for the best of you!

I have a cattery system which will be using the following tables:

tblCAT tblVisit and so on

I need to be able to check booking availibility. NOTE: THIS IS NOT THE SAME AS A HIRE-SERVICE SYSTEM. I.E. I need to be able to check the following:

1. For every day of a cat's intended visit...is there less than 40 cats @ the cattery

FOR EXAMPLE:

At the moment I can search to see how many visits will be taking place on ONE particular day. So the challenge is:

HOW CAN I REPEAT THIS QUERY TO CHECK HOW MANY VISITS ARE TAKING PLACE ON EVERY DAY OF A CATS INTENDED VISIT.

*At the moment, my querey can only search for the total number of visits taking place on one day...I need to repeat this as mentioned.

THANKS EVERYONE :D

I've Got A Challenge For You!

May 1, 2007

Here's a tricky little problem I am trying to figure out. I'm sure someone out there should be able to help me without breaking anything. Heres the problem.... I have a form that has an underlying table attached. I have a combo box pull in a pull down list of locations from that table. What I would like to happen is, I would like it so the user will select a location from that combo box, and then click a command button. When they click that button, I need whatever they chose in the comobo box to copy over to a NEW table, which will be referenced later by my program. Say the table being pulled from is called "table1", and the table I need the info to go to is "newtable". I guess it doesn't SOUND hard, but I can't seem to figure anything out on it. I'll let you experts tear it apart and tell me how dumb I am for not knowing. Be kind... I'm still a noob. :D

A Challenge

May 3, 2005

Hi,

I have been thinking about this since two day and tried everything, but no luck.

I have a form with recordsource a query. A listbox contains all references and if you choose a reference, everything else on the same form gets updated. Now i want to avoid that two users edit the same record at the same time. So i thought i would make an extra field in my table with a checkbox "yes/no" wich says if the record is in use or not. Now whenever a user edits a complaint i want that when another user is trying to edit the same record a message pops up saying that the record is in use. I can get it to work, but only have the problem that when a user decides to change reference number in the listbox and call upon another record, the value needs to get to fals again on the record he was editing.

Maybe there is another way to now if a user is working on a record.

Anyone that can help with an easy solution on this?

Bit Of A Challenge

Dec 21, 2005

Hi Everyone.

I am building an app which will be used to administer a small company which has several mobile service engineers.

Everything is fine. A fairly standard sort of job until the client asked for a screen showing each engineer for a given day with a bar graph showing planned start and finish times for each allocated job, together with the location! As an added challenge, I need the user to be able to click on the "Chart" and so open another screen showing full details of the job clicked on.

My first approach was to use a chart. Couldn't do it:confused:

The approach I have now used is to create a series of labels on the form "On the fly" to represent each job and the unallocated time in between jobs. I can also run a macro to display the full job details when the label is clicked upon.

HOWEVER, this is a very cumbersome way of doing things to my mind. In addition, sizing of the controls in each day's bar is far more difficult than I expected.

Anyone got any ideas as to how I might achive this task in a more polished way?

Here's A Challenge!!!

Jun 12, 2006

This is probably not too bad to most... Considering I'm still pretty new to this...

I'm designing a database to track training for about 6 offices where I work. I am having trouble trying to set up a questionaire that adds a worker's training requirements automatically when a new worker is added to the system.

TABLES

tblPersonnel
PersonnelID (Primary Key)

tblRequirements
RequirementID (Primary Key)
RequirementTypeID - Denotes the type of requirement based off of the question on the questionaire.

tblPer_Req (Join Table)
PersonnelID (Joined to tblPersonnel)
RequirementID (Joined to tblRequirements)

QUERY

In my query I have pulled the PersonnelID from tblPersonnel, the RequirementID from tblRequirements and the RequirementTypeID from tblRequirements.

FORM (part 1) - New Member Form

Enter the new member's information...

FORM (part 2) - Requirement Questionaire (Must bring over PersonnelID from FORM (part 1)...

I have asked the following question... (total of 10 questions, but we'll just go with one for now...)

"Does the member wear prescription eyeware?" (Yes/No - using an Option Group)
(RequirementTypeID = 2)

If the member answers yes, I want the database to automatically add the member's PersonnelID and all Requirements from tblRequirements that have a RequirementTypeID of 2 to tblPer_Req (Join Table).

So far, I have gotten the query to only work by itself as a SELECT query and was not able to add the information to tblPer_Req, let alone try to tie it together with the Option Group...

If anyone could please help me get this together I would greatly appreciate it... I've been trying to work this one through for almost two weeks, the boss has tried to help too but he's also stumpped!!!

Thanks!!!

Query Challenge

Apr 21, 2006

I have several Databases with similar tables with similar information, but entered differently. (Different persons made separate databases before my time) I would like to make new tables, write a query to combine the information into these tables, but I need to get the data similar before I can combine.

Example of information:

7L 24 3A719 AD one table might have it stored this way
7l243a719 AD another this way
7L24-3A719-AD or 7L24 3A719 AD both ways in this table
and so on. There are alot of combinations

I have been in attempting Mid$, Right$, Left$, Like, Not Like and others to no avail.

Looking to make all the information the same layout 7L243A719AD, then I will be able to combine information.

Any ideas / help would be appreciated.

A Real Challenge...help Me Think Outside Box Please!!

May 19, 2006

BACKGROUND

The current challenge I have in MS Access in really giving me a headache. I can�t seem to find an answer or indeed think �outside the box� so I am hoping there is someone who can help.

Below I will outline the design of my database, the problem I have and my proposed solution. My solution is �What I want to do� rather than �How I do it�. If you have the time and patience to look at my problem and suggest how I proceed, I will be really grateful.

CURRENT DATABASE DESIGN

I created a database that imports daily telephone data. The design below is a simplified version of the real thing but it contains the essential information needed to understand my database.

I extract data from the phone system for �Lines� (3 digit code) e.g. �301�,�302� which each have a corresponding line �Description� e.g. �New Customers�, �Accounts Queries�. There are three main daily extracts (1) Inbound Calls (2) Outbound Calls and (3) Time. Each extract has either �Line� or �Description� as the unique identifier but not both.

There are 50 lines with matching descriptions and each is allocated to one of 20 teams. I have a query which links all three extracts, groups the data by team and date. Therefore this query creates 20 records (teams) for each day (date).

CURRENT QUERY AND TABLES

Tbl Line Lookup (50 records)
Line
Description
Team

Tbl Inbound Calls
Line
Date
Offered Calls
Answered Calls
Abandoned Calls

Tbl Outbound Calls
Description
Date
Outgoing Calls

Tbl Time
Description
Date
Answer Time
Abandon Time
Talk Time
Wrap Up Time

Qry Grouped By Team Daily

Line � linked to line in Tbl Incoming Calls
Description � linked to description in both Tbl Outgoing Calls and Tbl Time

Team � Grouped field
Date � Grouped filed
Offered Calls - Sum
Answered Calls - Sum
Abandoned Calls - Sum
Outgoing Calls - Sum
Answer Time - Sum
Abandon Time - Sum
Talk Time - Sum
Wrap Up Time - Sum

PROBLEM

Customer Services �Team� is made up of six lines (301-306) and Business Partners �Team� is made up of three lines (307-309). For each day my query creates a record for each of these teams based on how the line is allocated in Tbl Line Lookup.

The business had decided that line 304 calls are part of the Business Partners with effect from 01/05/06. If I change the team name associated with 304 in Tbl Line Lookup this will, incorrectly, allocate all information (from 01/01/06 to present) to Business Partners.

I need a mechanism to allocate 304 to Customer Services prior to 30/04/06 and to Business Partners after 01/05/06.

PROPOSED SOLUTION

I want to introduce a new field in Tbl Line Lookup called Effective Date.

Tbl Line Lookup (50 records)
Line
Description
Team
Effective Date

Then I want to introduce a new query which links the data in the three data tables and allocates the correct team name by comparing the date in these extracts with the effective date in the Tbl Line Lookup.

I would then run my original query (Qry Grouped By Team Daily) over this query instead of the original tables.

Please can someone tell me if it is possible to look up values in another table to determine the value of a field in the way I have described?

Access Challenge!

May 22, 2006

The scenario - I use MS Access to access an advantage database system from a program we use. I can either import or link to each table in the program's database via OBDC drivers.

The problem - I need to track the status changes of our customers. Tracking customer status changes are not recorded in the advantage db. The TRDATA table contains the information. From now on, I want my access db to track the changes and save it in access for report purposes. The status's available are A, B, I, K, L, O, P, W, X and Y.

The solution - So far, I have queried the TRDATA table to pull the Account #, Buyer, and status. I made a crosstab query which would kind of aggregate the data into a readable form. If the account is active, there would now be a 1 in the column A. I then made another query which would then update a table. From here, I'm unsure of what to do. Obviously, there needs to be a comparison of some sort. If only account 1234 changes from an A to a Y, then I want a new table to show all the other accounts where they stand and a change of Y for the status with the date it changed. I hope I'm explaining myself well enough!! I�m very unsure of where to go from here.

Count Challenge

May 24, 2007

I have a problem!

I have a table, tbl_Members.

tbl_Members contains many fields, two being SName and RefferedBy.

ReferredBy is stored in the table from a lookup from a form that looks up the SName field from tbl_Members.

What i want to do is create a query from this table with an extra field which counts the number of instances based on the records SName, in a field called NoReffers.

For example, i want a query that looks like:

qry_tbl_Members:

-----SName-----ReferredBy-----NoReffers---
-----Bloggs--------Hills-------------1-------
------Hills--------Barnard-----------2-------
-----Smith--------Bloggs----------- 0------
----Truman--------Hills-------------1------
---Williamson-----Truman-----------0------

I 've been looking into the Count() function, but cant seem to work it out!

Can someone help me?

Query Challenge

Jul 24, 2007

Hi everyone, here is one of the tougher problems ive had to deal with.

i have a number of fields, called teammember2, teammember3 etc..to teammember12. This is done because on the form, the user is able to select team members in addition to their original selection using a button.

Another field on the form is a "total days worked".

The problem now is adding the total days worked for each record based on the team member

for example:

if record 1 has : john smith and jane smith as team members
and record 2 has: john smith and tom smith as team members

i need the report (query) show the total days worked for john smith as record 1+ record 2. and for jane smith just record 1. tom smith would show total days for record 2.

im sorry for the weird explanation! i will be happy to clarify anything.

I also need to count values that are between (and including) 3500 and 3999

My challenge is to find a way of counting one and not include the other

If Me.cmbLkpSCType = "3000" Then
strBuild = Me.cmbLkpSCCountry & (Right([cmbLkpSCYear], 2)) & (Left([cmbLkpSCType], 2)) & (Left([cmbLkpSCBudgetUnit], 2))
strCt = DCount("strSourceCodeID", "tblProjectSegment", "(Left([strSourceCodeID], 8) ='" & strBuild & "')")
End If
'*****************
If Me.cmbLkpSCType = "3500" Then
strBuild = Me.cmbLkpSCCountry & (Right([cmbLkpSCYear], 2)) & (Left([cmbLkpSCType], 2)) & (Left([cmbLkpSCBudgetUnit], 2))

Listbox Challenge

Jul 18, 2006

Hi folks!

I have a listbox in one of my forms with the following RowSource:

SELECT fsVisbetalingsprocent.navn1, fsVisbetalingsprocent.betalingsprocent1,
fsVisbetalingsprocent.fradato1 FROM fsVisbetalingsprocent WHERE
fsVisbetalingsprocent.s�lgernr1=forms.viss�lger.s� lgernr ORDER BY
fsVisbetalingsprocent.fradato1;

The output looks like this:

(navn1) (betalingsprocent1) (fradato1 is hidden)
June 0,50
August 0,30
August 0,30
August 0,30

In my query 'fsVisbetalingsprocent' the 'betalingsprocent' is allways the same when the month is the same. So I want the listbox to write the month (navn1) only once...

I've been trying hard for an hour or so, and I just can't get it to work!

Any suggestions???

Interesting Query Challenge

Aug 14, 2006

Hello all. Hope someone can help.
I want to know which of my customers received a particular service (service id: #199) during the last month. It gets complicated (I think) because of those customers that received service 199 last month, I want to know which ones did not receive any other services in the 90 days prior to receiving it. Any thoughts on how this can be done? I can find who received the service during the last month, but how do you check to make sure they have not received any others during the last 90 days?
Any help is much appreciated.
Thanks,
S.J.

Challenge On Crosstab Query

Jan 18, 2008

Hope any Access guru can help me with this problem.

I want to create a cross training matrix with crosstab query in Access to show the relationship between the trainers and trainees with purpose of the trainings from the following table.

XTrainID...Purpose.............Trainer............ .Trainee
1.............Web Focus......... John................Edward
2.............Search Engine.....Mary................John
3.............CEI................... Matthew...........Edward
4............SAS................... Paul..................Mary
5.............NET.................. Greg.................Sam
6............SAS................... Jennifer..............Mary
7............SAS................... Matthew.............Edward

The resulting matrix should look something like this:

............ Greg...... Jennifer....John.............Mary........Matthew.. ....Paul
Edward..............................Web Focus...................CEI, SAS
John.............................................. .......Search Engine
Mary...................SAS........................ ....................................SAS
Sam....... .NET

I tried to use crosstab Q and picked Trainee as Row Heading, Trainer as Column Heading and Purpose as Value - with the Total option as First, but it would only show the first purpose even if trainer with the same trianee has more than 1 cross training involvement. The example is for Matthew & Edward. In this case, it only show CEI but not SAS. My challenge here is how to concatenate training purposes with the same trainer and trainee.

Any suggestion would be much appreciated.

A Structured Query Language (SQL) Challenge

I'm working on a bespoke logging feature for a web portal which records user events in a single table (tblUserLog as illustrated below).

To supplement this flat list I'm preparing a number of key stats which will be reported to administrators (e.g. unique user/session count by period, app usage by period etc).

I'm now looking to report the (10?) most active users where most active means those users having the most unique sessions. The desired results are as follows:

User Sessions
joe 23
paul 10
chris 5
jim 2
... ...

Within Access its relatively easy to create/combine a number of queries to acheive this but I need to do this via an ASP script. The challenge is to design a single SQL statement (with nested SQL?) which will return a recordset as above.

Any help on this would be much appreciated.

Thanks in advance,

Rob.

Import Data From Another DB

Feb 17, 2008

so i need to keep 2 DBs with the same forms (But different data) for the purpose of single/double data entry. i have to constantly import forms from DB1 to DB2 because of the form changes, how do i keep the existing data and import it?

when i try to use the import wizard, it always imports the tables as duplicates. so here is the scenario if it helps to explain better:

1: import FORMS/TABLE structure only from DB1 to DB2
2: DB2 is EMPTY, no DATA, just forms/table copied from DB1
3: enter some data into DB2
4: DB1 forms is updated, so I have to re-import the forms to DB2
5: new DB2 is again EMPTY. how do I re-import JUST the DATA portion from previous DB2 version into new DB2?

hope this makes sense. please provide a step-by-step if possible. like what fields to check and how to use the import wizard. thanks very much!
