Tables :: Splitting Table Into Multiple Sets Based On Row Count
Oct 5, 2012
I want to split a table into multiple sets based on rowcount. Suppose I have a table having 10,000 records. I want different sets which should have values based on rowcount. Suppose if I select set 1 then the table should populate records from 1-2500. If I select set 2 then the table should automatically give the records from 2501-5000. If i select set3 then the table should have values from 5001-7500 and so on.

I need to count records based on multiple criteria from two different tables. I have two tables (i.e. "tblTasks" and "tblTaskHistory"). The tables have a one-to-many relationship based on the "TaskID" field. "tblTasks" has a field called "AssignedTo" and "tblTaskHistory" has a field called "TaskStatus". I need to know how many tasks have been "reopened", the "reopened" status is located in the "TaskStatus" field in "tblTaskHistory". I need this count against a unique listing of employees which can be found in the "AssignedTo" field in "tblTasks".

Good morning,
I am having problems figuring out how to set up my table/query structure for a series of surveys that are based on specific user groups. In a nutshell how do I set up the relationships for the Questions, Employees, and Answers if I have the following tables (simplified):
tblQuestions
--------------------
QuestionID (P)
UserGroupID
Question
tblEmployees
--------------------
EmployeeID (P)
Name
UserGroupID
tblAnswers
--------------------
AnswerID (P)
QuestionID
EmployeeID
Answer
The functionality requirements are:
1. Create a set of questions for two or more user groups (each set contain different questions).
2. Assign Employees to a specific user group.
3. Employees are able to enter the DB to answer the questions within their user group.
What should happen is the employee accesses their set of usergroup questions and enter the corresponding answers. Each time I try to set up the relationships however, the answer field ends up being uneditable.
Any help you can give would save what little hair I have left.
Thanks!
Bob

I'm trying to set up a way to import and combine excel files that contain multiple data sets. So for example, each excel file has a summary heading which consists of the first 3 rows.
Each data set thereafter consists of approximately 50-60 rows of data that I would like. There are approximately 1400 groups of data. Each group has a label which includes the state and the store number. I would like to automate a way to copy the state and store number information down each data set as well.
I have approximately 200 excel files that I want to load into access and have it format it so it basically will end up 1 big file with State, Store Number, relevant information from the data set. I've seen a module do this before, can't remember how to do it.

I'm trying to split a table up because I now realize it won't be able to do what I need in the future. It wasn't designed properly at the outset, and I'm trying to correct it now.
This is a database of pregnancies and deliveries.
The single table does not cater well for multiple pregnancies (twins, triplets, etc), and also I foresee problems when mothers come back in future for another delivery.
Therefore I am trying to separate data into 3 tables: Mother, Delivery and Baby.
This is because each mother can deliver more than once, and each delivery can have more than one baby.
I have set up a trial database, with just a few fields in each table to see if this works. An screenshot of the table relationships is attached.
The primary key of the Mother table is linked to the Delivery table, and ditto the primary key of the Delivery table and the Baby table.
I'm not sure how to migrate the data over, in terms of the primary keys of each table, because in the new tables, these should be an AutoNumber field, so that they are unique numbers.

I have a database composed of personal statistics. (name, age, height, wt, etc). I have two attachment fields. Photos and Videos. Each of these fields can contain more that one file. The size of the video attachments is starting to get me up close to the 2 GB database limit. If each attachment field contained only one file, I would convert the fields over to a path link. I'm stumped on how to move the files out of the main database to control the size, but maintain the multi-file link to my forms. How to restructure this?

I want to be able to make row searches for multiple sets of characters at the same time.The default setting cancels a row if I have inputed a set that is not on that row.Something that could be used in a store or by a lawyer looking for specifics.So these are what I am looking for:
Primary
1.) I want any row with any of the words I type to show on the results.
2.) I want the rows with the most matches to show up first.
Secondary
1.) Recognize sets of characters that are close to what I type to make up for spelling errors and typos, prioritize those that are closest.
2.) To be able to choose the rows I want and add them to another list quickly where the summing cost will be calculated in the last raw (multiplying the price of a row by how many the customer wants.)

I have a simple line chart plotting price against date.
I would like to plot a secondary line on this chart from an array of data that I calculate. I've searched hi and low but can't seem to find a way of doing this.
The closest I've found is from this:-

I can create my array of data but I can't seem to get it to work and think it may be for pivot charts....which access 2013 can't do anymore.
how to plot multiple data sets on the same graph in Access 2013.

Hi all!
What I need is propably easy to do. I have a patient information database, where patient information, visits, treatments etc. are on separate tables. One patient can have several visits and one visit can include several different treatments.
At this point I need to count how many treatments (treatment instances) each doctor has given (= a report "Treatments per doctor").
I have (at the moment) three (3) tables, which contain information of three different types of treatments. The tables are different, but each has a similar field with the doctors ID, and an autonumber field for each treatment instance.
tblTreatmentXX:
treatmentXXID, visitID, doctorID, (+ treatment-specific fields)
Now, I know how to count how many times each doctor has given a treatment *from one table* (group by the doctor's ID and then count the treatment instance IDs), but how do I combine the information from three different tables?
All help is greatly appreciated!

I am trying to generate a count report from a multi-table Access database. It is a recording database with a songs in one table, recordings in a second table, and a third table that links the two. I am trying to generate a report of songs with the most numerous recordings in the database.
For this operation, I don't need the recordings table. The main question is: For each title in the songs table, how many records are there in the links table with key number <50000? More specifically, for the report, I only care about the ones with a count >= 10.
Ideally, my report would look something like this:
65 Moon River
58 White Christmas
43 Autumn Leaves
42 Way You Look Tonight, The
etc.
As a corollary to this, how would I add a current, dynamic count to the form I use to access the database. Whenever a song title is pulled up, a field would show the current count of records in the links table with key number <50000.

Hi,
I am building a small sales application where I would like to get the number of opportunities created in multiple regions. The QUERY that I am using in MS Access is as follows:
-----------------------------------------------------------
SELECT OPPORTUNITY.OPP_CREATION_MONTH AS [MONTH], Count(*) AS TOTAL,
(SELECT COUNT(*) FROM REGION INNER JOIN OPPORTUNITY ON REGION.REGION_ID = OPPORTUNITY.OPP_REGION WHERE OPPORTUNITY.OPP_CREATION_YEAR=2006 AND REGION.REGION_NAME='REG1') AS Expr1,
(SELECT COUNT(*) FROM REGION INNER JOIN OPPORTUNITY ON REGION.REGION_ID = OPPORTUNITY.OPP_REGION WHERE OPPORTUNITY.OPP_CREATION_YEAR=2006 AND REGION.REGION_NAME='REG2') AS Expr2,
(SELECT COUNT(*) FROM REGION INNER JOIN OPPORTUNITY ON REGION.REGION_ID = OPPORTUNITY.OPP_REGION WHERE OPPORTUNITY.OPP_CREATION_YEAR=2006 AND REGION.REGION_NAME='REG3') AS Expr3,
(SELECT COUNT(*) FROM REGION INNER JOIN OPPORTUNITY ON REGION.REGION_ID = OPPORTUNITY.OPP_REGION WHERE OPPORTUNITY.OPP_CREATION_YEAR=2006 AND REGION.REGION_NAME='REG4') AS Expr4
FROM OPPORTUNITY
WHERE (((OPPORTUNITY.OPP_CREATION_YEAR)=2006))
GROUP BY OPPORTUNITY.OPP_CREATION_MONTH;
-----------------------------------------------------------
What I am trying to do is get the total opportunity count for each month, followed by, the total opportunity count for the REG1 for that month, the total opportunity count for the REG2 for that month,the total opportunity count for the REG3 for that month,the total opportunity count for the REG4 for that month.
Expected output should be something like this:
Month | TOTAL | REG1 | REG2 | REG3 | REG4
--------------------------------------------
Jan 11 8 1 1 1
Feb 4 1 1 1 1
However, I am not getting the above result. In the results that are displayed the "TOTAL" column is correct but under the "REG" columns the same number keep repeating in all rows. Any help will be appreciated.
Thanks.

I am trying to assign teams to players. I have an import table with all of the players information listed. What I want to do is determine the count of players in a given city. For every 9 players I want to add a new record to the Team table and assign the team number (auto incremented for each team created). Then I want to add the players to the Players table with the Team Number that was created.

I am working with 4 tables and I am trying to get a count of the email address field in each table grouped by Email Group Name. I tried the dcount function but returned an error because some of the email addresses have an apostrophe in the field. Is there a way to do this in 1 query? This is an example of the result I would like:
EmailGroup/TtlEmailSents/TtlEmailsOpened/TtlEmailsClicked/TtlFormSubmits
AAA 50 30 15 10
BBB 100 75 50 20
CCC 60 25 5 1
Tables:
Emails Sent
Emails Opened
Emails Clicked
Form Submits
Field Names in all tables:
Email Group Name
Email Address
Field I want to count is Email Address for each table, grouped by Email Group Name.

I am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?

Hello all
I have a table containing the following fields:
Customer ID
Customer Name
Countries
The ID is numeric, the name is a string and the countries are the tricky bit since it contains a string of concatenated 2 digit ISO codes: "USCAGB".
What I would like to do is convert the concatenated representation to a normalized one. Take this example table:
ID Name Countries
2 John SEDK
3 Maria USCAGB
From the above table I would like to create a new table that links Customer IDs to single countries as
ID Name Countries
2 John SE
2 John DK
3 Maria US
3 Maria CA
3 Maria GB
How would I go about solving this?

My db has several tables tb1, tb2 tb3 tb4 ..... I have link tb1 to tb2 (tb1Id to tb2)and linked tb2 to tb3 and tb4 (tb2Id to tb3 and tb4)
I have created a form with several field from tb1 and tb2 and a single field for tb3 and tb4. All of the fields except one for tb1 are use to make a decision based on what they display. The only field that is updated on the form is a date conversion field from tb1. once you update this field it will auto populate a date field on tb1 with current date. you then have a choice of 4 commands to activate based on what is displayed form the rest of the form.
my problem none of the fields can be updated. can any one help
qry the form is based on
tb1 [Name]
tb1 [ID]
tb1 [date conversion] 'this is the only field that is manualy updated
tb1 [date] 'updated base on date conversion field being updated
tb2 [field]
tb3 [Yes/no]

I've been playing around with a new database design and ran into a possible 'error' that I would like to avoid.
It's going to be a payroll database to store time codes for hours spent working on specific projects. I have been struggling on how to put this together to fit with what we've been doing for years and I think I hit a few breakthroughs this morning.
However I want to avoid this error of possible duplication of entry.
Simple table set up - primary key is just a running integer; Employee ID; and Week Ending Date.
I can have multiple week ending dates for a specific employee; but I want to avoid having the same employee with the same week ending date. I cannot set up either field as being unique.
Quick run of data that would be in this table:
Code:
1 ABC 11/21/2014
2 ABC 11/27/2014
3 ABC 12/07/2014
4 DEF 11/21/2014
5 DEF 11/27/2014
6 DEF 12/07/2014
7 ABC 11/27/2014
in this example, when the last row is entered I need to get a popup or some warning that this time has already been entered.

I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.

Hi All
Been handed a contacts database, one field of the DB includes all the industry sectors associated with the customer, with multiple industry references separated only by a comma within the field (e.g. Insurance-Life,Insurance-Broking,Insurance-Motor,Insurance-Pensions,Insurance-Home,Insurance-Health) – I want to split this one field into multiple fields using the comma as the break point (this is something that’s relative easy to do in Excel with the ‘Text to Columns’ tool – but unfortunately it can’t take the 130,000 odd records of the databasel)
Can any one recommend an expression or method that will see the 6 industry references split into 6 separate fields ?
Thanks
Jim

I am new to MS Access, and am not sure if what I want to do is even possible. It is my understanding that comparing subsequent cells within a field in a database cannot be done- so I thought I'd see if there is a way to go around it.
I have a dataset for pedestrian activity, with over 3 million rows and 40 columns - too big for excel to handle.
I need to sort the entire dataset by 2 fields, following which I need to search down the field containing my pedestrian ids (numbered 1, 2, 3... till approx 10000), and when my ped id changes from one to the next, I need to check the value in a field showing the ped location, and if that matches with the ped's previous location, I need to copy out a cell corresponding to the previous cell's time stamp. If it doesn't match, I need to copy out another time stamp from another field.
