I have about 500 tables that I'm upsizing to SQL Server, many do not have primary keys.
I can cycle through the tables container with VBA identifying each table and each table's respective fields.
How do I identify the primary key(s) of each table with VBA?
Thank you in advance for you assistance.
I have a table for a multiple parents linked to a child table. I need to figure out a way to only allow 1 parent to be coded as primary, 1 as secondary, and then the rest as other... I thought about making Primary/Secondary/Other a primary key. But then I can only have 1 other. I would have to make a finite number of parents that could be entered and I want an infinite number.... My end goal is to have a report that only has a primary and second parent on it, but the rest of the parents still exist in the table...
*Child_ID
Parent_First_Name
*Primary/Secondary/Other

Is it possible for the primary key of one table to act as the foreign key in another table for more than one columns? What I'm trying to do is create a table for a Committee which will have 1 student and 5 professors! So Can I import the faculty ID for each of the 5 faculty members?When I try creating the second relationship, access automatically creates a new Faculty table for the relationship!
View 6 Replies View RelatedI am accessing a SQL database using Access but its not letting me view the table in design so I can set a primary or letting me change the table names.
I am able to do this from my home PC but not at work. Is there something in options or ODBC settings on the work the PC that I need to change.
Any Help will be greatly apprectiated.

I have searched Key in the forrum and did not find quite my situation:
I would like to have a table that has a Primary Key that is a combo of 2 fields,
Example: Don't Allow a record to be created for the Same [Name] & [Date]
In the above the primary key would be the [Name] + [Date] but primary key only allows one field for key.
I'm still new in ADP development and need some advices and helps from you who has already expert on it. Fyi, I used Ms. Access 2007 and SQL Express 2005. I found a problem when working with my project. Here is the problems :
I'm using form wizard to create master/detail form but why I can't insert record in the detail section (the navigation button also became disable) ? The detail table doesn't have primary key only have foreign key that related to the master table. Should a table must have a primary key if we use ADP ? As attached is my relationship diagram.
Many thanks in advance
HI
I did some BAD planning before I started creating my database and I set a text field ("field1") of a table ("table1") as primary key, then I linked this field to a field in another table ("table2", one-to-many relationship). Now I wan't to change some values in table1 in "field1" defined as primary, but I can't (Access refuses to do so...).
Because I have a lot of data entered allready I would like to know if there is any way for me to change values in "table1"/"field1" and that all the linked fields in other tables ("table2") would change correspondingly??????
I hope my question is clear enough to understand.
thanx in advance
I am setting up an access frontend to an excel worksheet. I am creating linked tables using the excel input fields. I find when I have created the tables I can't create a primary key as access won't allow modifications to the linked table. Has anyone any suggestions as to how I can set a primary key on these tables. Thankyou
View 3 Replies View RelatedHello,
I want to have a table linked with an excel doc (which is easy to do with the wizard) but I want this linked table to have a primary key (which the wizard does not allow) because this table will be in a one-to-many relationship
How else can I do ?
thanks
Hello I have another prob. I need to be able to take a new ID from the topics table and insert it into the messages table after a form has been posted. I haven't got a clue on how to do this.
Its for a message board where a new topic is inserted. Two tables need to have records inserted, the topics table and messages table. The Topic_ID from the topics table is an autonumber and needs to go into the TopicID field in the messages table. Here's my insert query:
sqlString = "Insert into Topics (Topic, BSection, Username, MesDate) values ('" &_
Topic & "', '" & BSection & "', '" & Username & "', '" & MesDate & "')"
Con.execute(sqlString)
sqlString2 = "Insert into Messages (Username, Member_ID, Topic, Message, MesDate, BSection) values ('" &_
Username & "', '" & UserID & "', '" & Topic & "', '" & Message & "', '" & MesDate & "', '" & BSection & "')"
Con.execute(sqlString2)
I've tried using the identifier command but that didn't work so I haven't got a clue on what to do. Can anyone help?
thanks

Hello,
I have attached a screenshot of the relationships in (a section of) a database I am working on. Would anyone please be willing to view it and offer any suggestions as to whether is fully normalized or not? Here is the description:
An account [table, Account] consists of some money. That money is split-up and invested into several different places.
The funds that are available as choices are in Fund; the funds that are chosen are in InvestmentInstance. Different, unaffiliated accounts can invest in the same fund. I would like to keep track of when an account begins to invest in a fund and when it stops investing there (“InceptionDate” and “CloseDate”).
The generic, account-independent performance of a fund is kept in Price, where the values come from Yahoo! Finance or something like that.
Similar to Price, MarketValue stores the dollar-amount of an investment, specific to an account.
I think I have most of it set OK, but my main concern is about the relationship between InvestmentInstance and MarketValue. As the picture shows, I use InvestmentInstance’s “Id”* as the “one” in the one-to-many relationship, but “Id” is not a primary key. To get it to work, it was necessary to set the Index option to, “Yes (No Duplicates),” so that it was a unique index. Is this a bad practice? Should I just include “Id” as part of the compound primary key? I didn’t think making it part of the compound key was a good idea because then it would defeat the purpose of having “FundId” and “AccountId” control the uniqueness of records. Am I missing something important?
In other words, how can I correctly create a one-to-many relationship that begins in a juntion table (InvestmentInstance) and connects to a new table that was not involved in the normalized many-to-many relationship (MarketValue)?
Thank you!
* I know many like to include the table name in the ID, like, “InvestmentInstanceId,” and it is only my preference to keep it just as “Id” for a local key for simplicity, but add the table name when it becomes a foreign key. I feel “Id” is good enough for my purposes and it’s table location is usually clear from the context.
My database tracks all of the staff development sessions provided for the past ten years, thus we have thousands of records. Our school district wants all departments to move away from using an employee's Social Security number to a number assigned by the district. Each employee has been assigned a unique six digit number.
In my staff development database, the employees data (Social Security number, campus, job description, etc.) are in a table, "EmployeesTbl", with the primary key being the Social Security Number. Classes data are in a table, "ClassesTbl" with some of the fields being ClassNum (an autonumber), class name, class description, etc., with the ClassNum being the primary key
in this table.
A third table, "AttendTbl", links the two and shows each class (staff development session) each employee has taken. This table has a a foreign key, "SocNum", that links it to the EmployeesTbl, and another foreign key, "ClassNum", that links it to the ClassesTbl.
I have added the EmpNum field to the EmployeesTbl, and all of the the district assigned employees' numbers have been entered. I have also added this field to the AttendTbl. Is there a means of using a query to fill in the employees number in this table. Is so, I'll then change the primary key in the EmployeesTbl to be the employee number and the foreign key in the AttendTbl to be the same. If not, we face the task of having to key in 18,000 records!
Thanks for any help,

I need to build the following query:
I have 2 tables:
tblBusiness
tblInspection
tblShops have an ID, an adress, bussines name, owner name, etc
every Shop can be inspected many times. A inspection can be futile if the store is closed. If the store is open, the inspection is made, and as result with can have “with irregularities” “without irregularities”. Two or more inspections can be made the same day (if the n – 1 time the store was close).
So, here is the basic select:
SELECT tblBusiness.idBusiness, tblBusiness.BussinessName, tblInspection.InspectionDate, tblnspeccion.InspeccionTime, tblInspection.Open, tblInspection.Irregularity
FROM tblBusiness INNER JOIN tblInspection ON tblBusiness.idBusiness = tblInspection.idBusiness;
What I need is to get the LAST inspection where the bussines was open and with irregularies. One inspection per Business, but of all business. Ah, and if there ir a newer inspection but the business was close, it doesn´t count.
I tried “Group by MAX” with InspectionDate, but it just didn´t work. For example, it showed me two inspection of the same business, not “the last” of that bussiness (it was easy to filter the Open field and the Irregularity field).
I suspect that what I need to solve this is to use two or more SQL stament, two in one., something like that. But I´m in a hurry and I just can seem to get it right.
I hope you can help me with this. Thanks for reading anyway.
P.S.: the fact that there can be more than one inspection per day can be a bitch =(
but there is a "InspectionTime" that can save that". Mmm the problem is that one inspection can be made 1 july around 20:00, but the seccond on 2 july 01:00. But we store the two inspections in 1 july... so... that mens problem.
But that issue is not so important as the previous problem up there (well, in order to solve the seccond I need to solve the firts...)
PS2: I don´t know about the title...
Hi,
Anyone has the idea of creating primary key in a table using make table query?
Thanks.:confused:
In a many-to-many relation, one create joint table and use two columns of both ID's in a Composite way. This what the text books recommend.I had a Form/subform to view the relation between the two table. I tried to add to the subform a new relation Access did not allow me to do it. I can go to the joint table in datasheet view and ADD to my heart content observing the unique condition.
If I change the design of the joint table to auto as PK and the two ID's with no PK in either, I can update from the subform .WHY the Composite Keys do not allow me to update the joint table by adding new records in the subform ???
I have a table that has a primary key that does an autonumber in increments. Then I made some queries that will append records by date and then also another query that will delete what was appended. Then I created a reverse sequence of this process in case I change my mind and would like to put back the records I archived, however, when I do this, the primary key is now thrown off and will still revert to the last primary key that was appended before the archive ever took place. In other words it still thinks that the records I appended before I did the reverse, are still there. So now it will not let me save the record because it is a duplicate.
Is there a way to set the autonumber for the primary key to where I want it to begin?
I have an old table from a database with 2000+ rows deleted and it had no primary key (but it had a number column).
I am splitting another old table which relies on the number column of that old table but I am importing it into a new table with an autonumber primary key which the split table will rely on.
Thing is I need the number and the autonumber to match up accross all records
1 has to be 1
2 has to be 2 and so on
is there a way to "fill" in rows with the missing numbers? i.e. if I have 1,2,3 and 2 is missing the method adds a row "2" to the table.
How do I add multiple fields in the same table with the same primary key?
For example I have an employee with the employee ID 1 named john. He has two degrees. One in Math the other in science. I need to have both of these incorporated into my table.
when i import i have records deleted due to key violation, how can i get these deleted records to an error table so i know that the right record was deleted?

Anyone...
Please can you tell me how I run a make table query that makes one of the fields a primary key. Can it be done in the query or do I have to set it as part of a macro that runs the query. If so How do I achieve this.
I am running a make table query from a link table so i can use it with infopath. I run the make table query every time I update the spreadsheet that the link table runs off and it makes a proper table with it for infopath to run off (because I can't get infopath to run off a link table, No primary key means it won't submit.) When I run the macro that runs the query and creates the table, I need it to make oone of the fields a primary key.
Any suggestions
I am trying to create a new Table using a MakeTable Query
using the following sql:
Code:SELECT qCPPlannedStopsOnTargetTotals.WeekNumber, qCPPlannedStopsOnTargetTotals.Line, qCPPlannedStopsOnTargetTotals.Description AS Above, qCPPlannedStopsOnTargetTotals.[%] INTO mkCPPlannedStopsAboveFROM qCPPlannedStopsOnTargetTotalsWHERE (((qCPPlannedStopsOnTargetTotals.Description)="Above"))ORDER BY qCPPlannedStopsOnTargetTotals.WeekNumber DESC;

Hi
How can I make the primary key (participant #) in my table equal the record number on the Form? In other words, when I open the form, I need two things to always happen:
1. the primary key must equal the record number (which is displayed on the form)&
2. when I click "Add New Record" button, I want a new customer # automatically generated and in the correct order.
Is this possible? I've been struggling...
