Create Tables From Another Table
Oct 17, 2005
Hi All
I am trying to create a database for estimating manhours on projects. There is a setup table with two columns: "Project" and "Time Period". The database is supposed to allocate manhours to tasks on projects, which is used in estimating man hour costs and also forecasting labour resource requirements.
For example, say the database is used for "Project X" and "Project Y" projects, with Project X running from Jan to March and Project Y running from Aug to Dec. The setup table would look like this:
PROJECT TIME PERIOD
Project X Jan
Project X Feb
Project X March
Project Y Aug
Project Y Sept
Project Y Oct
Project Y Nov
Project Y Dec
From this table, I need to automatically create a new table for each unique project that allows man power to be allocated to each time period. Following on with the example, there are two unique projects, so two tables
need to be automatically created with column headings as per below:
Project X table:
FUNCTION PERSON JAN FEB MARCH
Project Y table:
FUNCTION PERSON AUG SEPT OCT NOV DEC
"Function" is a description of a role, for example engineer. "Person" is the individual undertaking that role, for example Bob Jane. Then in each time period a number between 0 and 1 would be entered corresponding to how much time (0 is no time, 1 is full time) that person would be spending on that function for that time period. Then the table would be populated with many functions and people in this manner.
So the number of tables automatically created depends on how many unique projects there are in the "Project" field of the setup table. The number of columns in these tables will be atleast two: "Function" and "Person",
plus another column for each time period defined for that project.
Perhaps something can be done with a make-table query, but all I can get that to do is copy data from one table straight into another table.
Any help would be greatly appreciated.
Thankyou in advance.
Joey

I have a make-table query that pulls all the fields from 1 table (MainTable), and creates a new table with a date stamp based apon a form value entered (New Table = MainTableWithDate).
Currently, I setup the query to pull info from the form field like this:
DateField: [Forms]![frmmain]![DateField]
However, when the make-table query is done - all date fields are blank (all other fields are correctly created), and when I look at the new created table (mainTableWIthDate), the typeassigned to the date field is "Binary" (in the form, I've specified LongDate).

I have three tables that contain different columns but linked by a primary column call Name. I want to create a table where all these different columns in the three tables join to form a master table which can be updated regularly either through the master table or the smaller tables. The master table also has the primary column as Name.
If I update the master table with records, it should update the respective linked table and vice versa. I also want to link these tables to my SharePoint site.
Note: except the Name column, none of these tables have any other columns in common How do I go about this?

I'm new to MS Access, indeed database design as a whole.
I have been tasked with creating an issues logging database and am having some issues...
I have a table/form that has all the fields I want, including a unique ID, called "Issues". I want to be able to log multiple entries in another table called "emails". The trouble is I am not having much luck. I can create an entry in the issues Form which then shows in the emails but I can't then add another email under the same ID in the "Issues" table.

Hi,
I have two tables:
Table A provides total sales volume of the UK shoe market from 2000-2007.
Table B provides the sales volume of different shoe manufacturers from 2000-07.
I want a third table created, called Table C. This should look exactly like Table B but instead of sales volume it shows percentage sales that are calculated by using the figures in Table A and B (i.e. [sales volume from Table B/total sales volume from Table A] * 100).
Could someone point me in the right direction please (assuming that such a table can be created, based on a calculation of figures in other existing tables).
Thank you.

Is there a way of creating a log to capture changes in a table by users?
In a current database that I'm taking over, there was a lot of records deleted from the main table and now I need to figure out what happened.
So, if I would be able to have a log that records all the actions taken by users, I could at least see who did what.

I have a rotating number of tables that are created from excel spreadsheets that are imported. The Tables will change, but when they are there I need to be able to create a query that will merge them all together so I can run one query against all the tables. In SQL I know you can use a * to say Select *
From Table_1
Is there a syntax for the From portion so I can say:
Select *
From * (AKA all the tables in the Database)?
I have searched for a wildcard for the FROM statement that works like in the select statement but have been unsuccessful at finding an answer. Can anybody help? I'd list the Tables in the from Statement but there are 266 of them. Unless someone knows how to say:
Select *
From All tables in a folder with 266 excel spreadsheets
Thanks for your help
:)

I am a newbie when it comes to Access and ASP but I am trying. I am in the need for some help.
I have a large table in Access 2003 and need to break it into smaller tables (not using a query) where the fields are the same except each of the smaller, new tables will hold info for a specific person. These smaller tables would need tro be linked to the larger.
Is there an easy way to do this? I need to keep it in tables due to the ASP software I use to generate the asp pages.
Is this possible?
My goal is for each user to be able to only view/edit their data and for the large table to reflect any changes made to the smaller table.
Thanks,
Dan

Table has a relationship with master table. Joined on TractID primary table - auto number, TractID child table - number. This works as it should when adding a new record.
What I am trying to do is create a new key for each new record added in the child table with an ID that looks like this: TractID.A, TractID.B, TractID.C etc. for each new record added in the child table. if so where do I look, how to accomplish it?

I am wondering if it is possible to automatically create a new field in one table whenever a new record is entered in another table. The name of the field would be the primary key entry of that new record.
I have one table (table 1) in which each record corresponds to a particular mouse with a unique ID number, and each field is the ID number of a particular genetic marker. The table overall shows what genotype (+ or -) a mouse has at each marker.
In the other table (table 2) the primary key of each record is the ID number of a genetic marker, and the fields are several different bits of information about the marker (e.g. what chromosome it's on, its location on the chomosome, etc.)
I would like to have it set up so that if I enter a new genetic marker in table 2 a field named after its marker ID will automatically appear in table 1. Is there a way to do this?

I created two tables, let's refer to them as Cars (VW, BMW and Audi) and Colours (White, Black and Grey).
Is it possible to create another table based on these tables - i.e. in the new table the rows will be the Cars and the columns the Colours as such:
White
Black
Grey
VW
BMW
Audi
And should I enter another Car or Colour in one of the first mentioned tables, then I would like this "new" table to update automatically. For example, if I have a new Car (say, Merc), then I would like the "new" table to update to the following:
White
Black
Grey
VW
BMW
Audi
Merc

I've only just started using Access 2007 at my new job. I've been asked to create a database that will show appointments for all 10 of the employees. I have created a table for the main schedule (where ill put all the data) then one for each of the employees. I've managed to link the tables no problem but it wont let me create and updating relationship. It keeps saying "no unique index found for the referenced field of the primary table". How do I fix this?
I want it to automatically update the date, time, location, customer name and description, if its changed on the main schedule for a certain appointment on the corresponding employees schedule.

I am developing a database which will track some of my companies clients bonus trips. Basically everyone is going to the same place but folks are of different levels. Level A is a 14 day trip with X number of activities, Level B is a 10 day trip with Y number of activities and so on. The major things I'll have to track are all of their personal information as well as 'Air Travel', 'Hotel Stay', and 'Recreational Activities' information.
I can put all of this information in to one table (tblTraveler), or am I better off with creating tblTraveler holding only personal information and then linking to other tables such as tblAir, tblHotel, and so on? I'm not entirely new to Access, but no pro yet for sure. Only problem with creating one table is that it would have one whole lotta fields. Not sure if it's better developing technique to split everything up.
Also, the only thing I can come up with as a primary key is the people's last names. The client numbers are the same on many of them, so that's the only thing I can come up with. The PK really is only a factor if it's best to create multiple tables for the traveler. At first I thought it was best to split everything, but now I'm seeing less reason to take all of the travelers information and dump in seperate tables since most of the time on the master reports the trip planners want everything lumped together. Perhaps I'm better off just keeping the forms clean and seperate and just one table? The reports will do the rest for me. Any input greatly appreciated.

hi everyone,
i think this must be easy but im new and despite reading lots just cant figure it out.
i have 2 tables
job details:
autonumber
customer
location
time
picking list:
autonumber,
equipment1
equipment2
equipment3
both the autonumber are primary and linked in a relationship.
when i create a new record in the job details table i need it to automatically create the coresponding blank line in the picking list table with the same number. If I enter something in the picking list table then it creates the matching number and everything is ok but if i dont then it throws my numbers out.
any idea how to get it to do what i need,
thanks

I am a newbie to access and i am working on a project that has two tables
the primary table has for example the following fields:
firstnameID(primary key) data type auto number
Firstname data type text
the second table has for example :
LastnameID(primary key) data type auto number
Lastname data type text
FirstnameID (foreign key)data type number
I created a relationship between the FirstnameID in the primary table and the FirstnameID in the second table ..
My problem is this whenever i try to view the relationship when i open the primary table it don't show the relationship ,
The Field FirstnameID in the secondary field is always Empty the only time the relationship is created is when i manually insert the autonumber that is generated in the FirstnameID field , but i thought that since a link was created then that field would have automatically be inseted with data , am i assuming wrong or am i doing somethingn wrong? how do i get the autonumber to be inserted in the field automatically to create the relationship?
Please Help

I am unable to create a new record due the the following error "The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. " I have looked everything over and can't find how the duplication is occurring. I am pretty sure it is the primary key of a table called Squad, but it's set to autonumber. I have uploaded the database hoping an experienced or fresh set of eyes could spot the problem. The goal of the database is to track squad inventory along with officers assigned to the squads. The main form is generically called "unit_Numbers" which uses "Squad Subform". Everything else seems to work correctly except for creating another squad.
