Created Linking Table
Mar 12, 2013
I have a database with the following tables (among others):
tbl_Projects
tbl_Staff
tbl_ProjectsStaff
tbl_Payroll
tbl_Training
tbl_Clients
tbl_ProjectClients
tbl_ClientContracts
tbl_CostEstimates
As you can see I created two linking tables (project/staff and project/client).After that I linked other tables to the liking table. For example, tbl_Payroll and tbl_Training are linked to the tbl_ProjectStaff primary key.
I don't know much about access so I wanted to check if this is a correct design. I create forms that work well, but I noticed that the linking table doesn't have any data in it. The payroll table and the training table have the staff iDs and Project IDs but the tbl_ProjectStaff is empty.

Don't know where this question will rank. Completely weird or completely common.
I've been getting great suggestions from this forum, one of them was to begin creating seperate tables for our data (I'm currently cleaning up a mess created 10 years ago for a nonprofit). The best way I have found to link/associate/whatever tables is to use their STUDENT identification number (since this value never changes). So we linked tests to that number (many tests to each student) by entering each new test as a seperate item with a manually entered stu id. We linked TUTOR and so forth the same way. But now I would like to start linking some more things. Particularly INSTRUCTION HOURS.
The question I have is this. How do I automatically create a value in the HOURS table that links to the value (stu id) in the STUDENT table. So that every student (previous and new) will have ONE associated HOURS set each time new student data is entered.

Dear Access Expert
I wanted to know if it is possible to change the name of the Table which is going to be created using a Make-Table Query via code (VBA).
For example if my Make-Table query currently creates a table with the name "Table1" I want to change it to name "Table2" and then change it Back to "Table1" or "Table3" etc.... depending on the users selection.

I have two tables. The first one is as follows:
MP No (Primary key), Sales, Date Entry, Specs, Email
The second Table is as follows:
MP No, Quantity, Description, DWG, Price
There is a "one-to-many" relationship between the two tables through the MP No field so whenever I go to the first table there is a sub-table for each MP No. Correct?can I create an extra sub table under the sub table already created?

I'm using access2003 and i want to organize a large amount of files in my company. There are thousands of files and I'm breaking the files up based on the dates. I want to create a table that automatically looks in each folder and links the job file with the job folder. This way I can create a custom query so a user just types in the job name and it will display what folder it is in. Can anyone out there help? Thanks

I have tables in a database that are not ticked replicable at present (tick button is greyed out), this is causing
the records in the table to become scrambled when we attemp to replicate the database.
Any advice please, with over 50 tables in the database we don't feel inclined to start from scratch.
Any help appreciated.

Anybody able to help me with this. I think there should be a simple solution to it, but it eludes me at the moment. Basically, I have created a form in MsAccess with alot of vb script on it, but
now I realise that I have to add more fields to the source table.
If I insert a new unbound text box onto the form, how do i bind it to
the new field in the source table. is there a formula that I should
use? When I look at the dropdown in the control source property, it
only gives me the fields that were in existense at the time the form
was created?
your help appreciated
thanks

I have just split my multi-user DB into Front end and back end. All appears fine apart from there is code in the autoexec module that checks to see if a particular table has been updated today. Basically the first person to login to the DB each day will run this procedure without realising. Now I have FE & BE however, because the query used by the autoexec module is a "Make table" query rather than delete all data and use an append query, every person logging in is running the update each day if it is the first time they have logged in on their PC and they are getting a local table on each of their computers. Is there any code that will create the table in the networked location (when the first person of the day logs in), rather than me having to change all my "delete table" queries to cleardown data and then re-append updated data?
There are quite a lot of delete queries in my DB and I am now worried that I shouldn't have split the DB as I may have caused myself loads of work which I don't have time to do.
I have looked on other threads but cannot find the answer and would greatly appreciate some help

Is it possible to have the Date/Time appear as part of the name of a table? I don't want to create and rename a table I want to run a Query that will create a Table that will have the name + date or just the date.
Example
"Todays file 20070308 11:10:34 AM"
or
"2007080308"
Or
"2007080308 11:10:34"

I've been having problems merging a spreadsheet with data into an already created table..
The main things in common is the "MC", "First Name", "Last Name".
I'm trying to update dates etc that are on the spreadsheet exported from another database, and update my datebase with those new dates..

I am currently working on a Database to automatize some process.
The User can import a CSV (Text) File via a DialogBox, which gets imported into a Table. After this, the content has to be filtered, setting conditions on 4 different rows. The new Table gets exported into a new CSV (It has to be CSV, since it later gets imported into SAP)
How can I set a Filter on a dynamically created Table (using VBA)?
Best case would be to save the filter into my Import spec, but Access doesn't seem to have this option (?)

Okay I had an idea and I thought I might get ffedback as I am relatively new to this. I went through a period a couple of years ago when I used access alot and was becoming familiar with VBA etc but I havent touched it in 2 years so Im pretty rusty.
I am running a study and need to have to create a database that:
a. collects data about participants
b. Has a number of questionnaires (5), each of which can be filled out by participants.
THe main table has a number of fields that collects info about the participants the most important of which will be the ParticipantID - an automatically generated number which is my primary key.
In table 2/form 2 I will host questionnaire one. This will be linked to Table 1/Form 1 (Particpant Information) by this tables primary key - also the Participant ID. The relationship will be 1:1. Each participant can only have one Participant ID and will only need to fill out questionnaire one once.
Is it possible that when I add a new participant to the Participant Information table/form I also automatically create a record in Table 2/Form 2 (Questionnaire 1), as well as Table 3/Form3 (Questionnaire 2) and so on so that they have the same ParticipantID...?
I was reading a similar query somewhere else and they said to use the Form_AfterInsert Event command? Is this right (see here http://www.pcreview.co.uk/forums/thread-1687644.php)?
I feel a bit stupid but I am willing to learn and try new things Once I get started I think I will be okay. If you could steer me in the right direction it would be much appreciated.

I created a table in MS Access using a Lookup & Relationship data-type. This means that my record cells call upon a particular table for values. It creates a LIST of values for that cell.When I query a particular value in this table I get every possible combination of the value. My query and code are below:
OR,
SELECT MainT.Content.Value, MainT.Source, MainT.[Entities Impacted].Value, MainT.Update,
MainT.[Divisions Impacted].Value, MainT.Announced, MainT.Effective, MainT.Stakeholders.Value,
MainT.[Ref#ID], MainT.[Issuing Agencies].Value
FROM MainT
WHERE (((MainT.Content.Value) Like "*" & [Forms]![SearchF]![ContentCB] & "*" Or (MainT.Content.Value) Is Null)
[Code] .....
This means that if I query STATES: "California", I'll get back every possible combination that exists with the name California in that particular field.The issue with this is that I'll get MULTIPLE primary key values rather than just 1. So, if one record, under STATES has California in it, but the other fields in that record have the Lookup & Relationship data-type, then every possible combination of that record will query instead of the multiple field-values form that you'll see in the table I am querying.
notice that my primary key (REF#ID) is repeated numerous times! This obviously causes problems with generating records and forms concerning information for 1 particular primary key. Is there a way around this problem other than specifying search criteria down as much as possible?! Perhaps there is some SQL code.

Is it possible to do this through vba. If security is setup for all the tables and a user goes in and creates a new table, can that table have security applied to it using code?
So maybe the creator of the table has read/write privileges but everyone else only has read only.

Ok...I have an issue that I don't know how to resolve.
I have a table called 'orders' in the orders table there is a place for " quantity', 'colours' and per unit. The cost per unit is based on quantity and colours.
For example: 12-35 shirts 1 colour are $2.85 per unit. 12-35 2 colour are $3.50 and so on.
I would like to be able to put in the quantity and # of colours and the Unit price fills in a field.
I don't know how I can accomplish this.

I have created an Access database application that is stand alone for each account manager/client at our business except for one table that I want shared as a source of data across all separate databases that are created.
I've investigated automatic Database Splitting and this works, except I only want the one table to be split and the others remain unique to each database.
I tried exporting the table in question to another Access database and then linking the table into each other database, this seems to work except that referential integrity can't be set up as it was. Is there any way to keep the integrity between the external database and the databases it links to?
Thanks in advance for any advice.

Hoi,
I'm using 2 databases. The first is my working database (LiTiMA.mdb) the second database (LiTiPA.mdb) is just for the password table.
There is no link between the 2 databases. But when I open a form for editing the password in LiTiMA, a connection need to be created between the 2 databases.
If the form is closed the connection need to be removed.
Does someone know how to do this?
thanks

Hi there,
The aim of this (as part of a bigger solution) is to create an entry system where users can enter jobs in, assign a resource to the job and give the resource a cost. The conditions are that resources can be on more than 1 job, more than 1 resource can be on a job.
Obviously entering in resources manually is not a good solutioon (eg having 20 resource fields) as it is now. I want to create a relation between tables to achieve something better.
Let's say I had (for illustration sake) 2 tables, one which is a list of people and one which is a list of jobs. I want to be able to assign a person to a job for x amount of time (defined by a start date and end date in the job table) at cost y.
So we could have a field for the people table which would relate to the job id and a field for rate in the job db. However, people can be on more than 1 job (eg after doing one they do another) and there can be multiple people on a job (having one field for rate rendering it useless)
How can this be done in the most efficient way so that any job could be looked at historically and have the relevant rates etc? Would I have to create another table with rates relating to the job ID and person ID? This would allow for multiple resources per job and to have a rate assigned for each resource.
eg if person ID = 1 and job id = 1 then fetch rate etc and display in a list, and to calculate total cost simply sum all rates where job id = 1?
Thanks

Hi guys,
I have been linking text delimited file to my Access table. The text delimited file is generated by a report run by our in-house system. I've been able to do this. Now, I want to learn how to link a datawarehouse (ODBC?) cube to Access. Is there a tutorial somewhere I can perhaps start? I tried to search this form by typing "Linking datawarehouse" I only found one post.
Thanks

I am pretty new to creating relationships between tables. I have a main form with subforms embedded. I tried running queries from the main form and they run just fine. I also run from the tables linked to the subforms just fine. however, when I try to run a query for a report that takes data from the main form and joins with data from the tables linked to the subforms all the data cells are blank. I have a linking table which is also blank. All the forms are linked by the same program ID number. Any ideas on how to resolve this? Thanks

Hi,
I have been thinking of allowing our users to be able to link records together within our database.
We have a CRM system that lists customers and their details of mortgages and other insurance related products which they have. Some entries maybe linked in some way, possibly other family members etc.
My question is, is it possible to perform this kind of action? So they can then see relationships between either related records (ID ref etc).
I'm sure I've seen this in SQL based applications, but haven't come across it within Access.
Thanks
Matt

When running a query i have created an expression which is simply 2 fields joined together. JOBLOC:[JOB]&[LOCATION]. I want to link this expression with a field in a second table [SCOPE], but for the life of me can't remember how i did it. Either in query design or SQL.
Thanks for your help!

Hi.
I have a table with Basic Client Data including their program start date.
One type of service they might, but not necessarily, get is job training. So I have a Training table.
I need a query that will show all client's names (found in Basic Client Data) with a specific start date but exclude anyone who has a specific job training service.
How to set up?
