Tables :: Invalid Field Definition - Not Able To Set Up Cascade Update
Jun 9, 2014
(named: Invalid Field Definition - Unable to set up cascade update but I have done what the moderator advised and have not been able to fix a very similar problem.
I have planned a database and must adhere to the plan or change it and basically I initially said that I would like to enforce referential integrity to synchronise my tables and I would also like to cascade update and delete to save input time because changes will be automated between table (where fields are connected.).
I have attached a plan I did if that makes the purpose of my database clearer.I have attached my database and have established the relationships* without referential integrity enforced I would like between my tables but don't know how to make them one-to-many relationships nor can I enable cascade update or cascade delete or enforce referential integrity.
I am new to databases (and to this forum) and have been promised by my line manager that I won't have to specialise, I don't think I have created the relationships but they are supposed to be between Vehicle ID and Hire Number, and Customer ID and Hire Number.

I am creating a database for my school and I can't create a relationship between two tables. There are only two tables and I need them to be one-to-many however it says there is an 'invalid field definition'. I have attached the database.

I've done this tons of times, so I don't understand what's happening... The title says it all: when I update the ID of one record of the main table, the referenced records on related tables won't update even though they have a relationship between them with the option "Cascade update" clicked.
In the attached database, the main table "Expedientes" is related to table "Actuaciones".

Is this scenario considered bad design form? (see attached image)
I'll never delete a Customer or Site for whom a a Job exists. I need historical data to remain intact. I'll just mark a Customer or Site as [InActive] so they can't be used, when appropriate.
If the relationships are considered good form, then what is considered good form when deciding upon which relationships to set to Cascade Update? Do I even need to update autonumber foreign keys?
On upsizing this database, SQL complains that this arrangement is a cyclic update and won't create the relationship unless I tell it to use Triggers. This leads me to question whether I'm correctly using Cascade Updates in my Access db's.
Thank you.

What I'm trying to do is making Cascade update and delete between two tables. For example in my case I have Field called Full name in table1 and I want the same field in table2 that will update when something is added in table1 and vice versa. I have tried relationship but I got an error that those fields does not have any unique value.

I would like to import excel sheet that contains about 45 fields and the fields names are not well defined(not obey the Access rules). I would like to import the sheet into ms access without changing the excel sheet because i have to provide only the interface to users where they have to import sheets only. (All the time In Excel fields name are arranged and in specific order but invalid names of fields).
After 1 week the person has new excel sheet with same format and the process of importing data into ms access will be continue for whole year or more.

Hi,
I have a database with a couple of tables. The primary table has a primary key called "StaffNo". I checked the relationships between the primary table and each related table, if I have ticked on the boxes for referential integrity, cascade updates. All done. If I now create a query, which selects the primary table and one related table and enter a new StaffNo, I would expect to see the new StaffNo not only in the primary table but also in the related one. But there is nothing. Do I expect wrong? Have I missed sth.? I read a few posts in this and other forums reg. referential integrity, but I have no clue, what's wrong. :confused:
Any quick help is much appreciated.
Thanks :)

I'm a newb to Access and SQL and database management. I have a main table and a dependent table with a 1 to 1 relationship, relationship integrity and cascade update and delete. I used an append query after I had modified several records, and after the append deleted one of the records from the main table. It remained in the dependent table. Access didn't catch the disparity even after a restart. I broke the link and tried to reestablish it, and of course Access wouldn't let me. I deleted the record manually from the dependent table and all was well.
Why would referential integrity/cascade delete not be recognized after an append query?Access 2010.
This is the second time in two days that cascade delete has been broken in two days after using a query on the main table. Yesterday, after referential integrity was broken, deleting the records from the dependent table allowed me to restore Cascade Delete functionality and it worked for the rest of the day.

I had a problem. Now I decided to just make two tables, one with sales for a "passer by" and/or directly to a client without a case/labour costs. And a table for sales in relation to a case with labour costs etc. I guess I still m*ssed up on that part and have to make do with that decision (kind of like I depicted in the photoshopped image).
For invoicenumbers I want to use DDMMYYYYHHMM. When adding that field to the design of a table, how do I go about that? Do I just use a Text field and create an input mask for that? Or do I need to use a number format with a certain input mask? Or would it be wiser just to use the date/time type of field and give it a new inputmask? I guess 000000000000 would be the one for that, right? Although I read the help file I do not know if I should use ;0; behind those first group of zero's or not. Yes it is a mandatory field, but it will fill in itself as soon as a product is typed in in the product/invoice list, with a default value of the current date and time.
I need to brush up my knowledge on the formatting for that so that 28-05-1975 19:55 will be displayed and stored as 280519751955. Or is that also done automatically by using that input mask? Or will that give an error when Date or Time() etc. is used for that field in VBA?
Just a few questions I need some help with, I've been trying some stuff but it really doesn't "stick".
And if anyone has some time, I could really use some general advice/ideas for setting up the invoicing part differently for a new version of the db yet to come in the future.

I have a query based on a query, when I added a new field to the base query, this field did not appear in the list of fields in the design definition when I try and add to the upper query. It just shows the original fields only.
Same thing happened in a field on a report - I had to delete the field and create it again...

I am developing a calender to display HOTEL room occupancy (past,present) and combine with future "outlook" dates and 1/0 values from active registrations that go beyond the present date.
I am working with MS ACCESS 2007. My problem is ONE SPECIFIC QUERY AND IIF STATEMENT. I want to concatenate some text (using &) along with numbers converted to text (using the CSTr function). I am using iif function and I want to use the full text string as a variable argument to be executed in the iif function. The result of the &concatenate is a text field like [p1] or [p2] or [p#] with numbers 1-31.
But, I do not want the final result as the argument. I want the query and iif to use the string expression written into the argument as the variable argument that can be calculated based on OTHER numbers that change everyday in the daily run of the calender.
The field in the statement [calc number] is a date conversion factor that changes everyday.
I want the iif statement to execute using the string as a variable argument. I am writing only within the QUERY to define the query object. I am not writing into any SQL module or code. My field definition and iif statement is below (calc number changes everyday)
CalDate18: iif(18 greater date();"[p" & [calc number] & "]";0
I do not have greater-than key on this international keyboard !
When I use this in an update query, I get format conversion error. When I use the same definition in MAKE-TABLE query, it gives the resolved value "[p1]" for the value of [CalDate18] ......... that is not what I want.
I want the string to be taken literally and executed. Seems there may be a special character to precede the argument or WRAP the argument such as done in Excel. Example # "[p" & [calc number] & "]" #

Hi, I was wondering why the following code would give me an invalid SQL statement message:
Dim Rs As New ADODB.Recordset
Rs.Open "Manzanero # 450", CurrentProject.Connection, adOpenKeyset, adLockBatchOptimistic
The error message is:
"Invalid SQL Statement; expected 'Delete', 'Insert', 'Procedure', 'Select', or 'Update"
I'm just trying to open up the table "Manzanero # 450" so that I might add to its contents. I have Microsoft Active X Data Objects 2.6 library included as well. I find it strange since this is basically a line for line copy of a sample I found in a MS Access book. Please help. Thanks! =)

My issue is an existing database in ms Access 2007, it runs great on the local computer, but now we are trying to share the database with other computers in the office across the network. We get an error when trying to open the database from any machine over the network
windows 7 home premium 64bit is hosting the database, trying to access the database across the network from windows 7 ultimate 32bit. I have mapped a drive to the shared folder of the database and added the network location to the trusted locations, I then placed a shortcut on the desktop to the database files, but I get an error that access can't find the tables, showing the correct path to the tables. "z:databaselah.mdb" What am I missing?I can open access and then open the tables from within access in table view, but in form view I get a blank page.

I wrote a database several years ago and recently pulled it out to give to a friend. The problem is, back then (not knowing better) I set the Employee table up with as a single field "NAME". Now, in order to make it effective, I need the Employee's name in four (4) parts (First, Middle, Last, Suffix).
I have several queries based on the "NAME" field and and would like to avoid changing all of them. I have a simple form "frmUpdateEmployees" that populates the Employee table and Name field. I was hoping to change the form and/or add a query that would be easier and more simple.
Table: Employee
Field: Name
Form: frmUpdateEmployees
Queries: 16 that depend on the table and field above.

I have a field in a table that is to be concatenated from two other fields, PolPrefix and PolNum. On a form I got it to show the full field 'PolicyNumber' by making the control source =[PolPrefix] & [PolNum].
But this doesn't update the field PolicyNumber in the respective table, and only shows it on the form. How do I get a concatenated field defined by the user into a table so that I can call that field other places in the database?

Having issues with getting auto update of Yes/No field dependant on todays date.
When users open the form the code runs through and checks all entries and updates the records if either of the dates in two separate fields is less than today. The issue I have is when some users are already using this form a second user cannot open it. Error shows other user information as having the form locked and code halts at highlighted spot below. Is there another way of ensuring this field is updated to Yes or No if the date in the field is less than current date.
Code:
Private Sub Form_Open(Cancel As Integer)
Dim rst As DAO.Recordset
Dim dbs As DAO.Database
Set dbs = CurrentDb
[Code] ....

I'm having trouble converting text to proper text in Access 2010 using Windows 8.1 as OS.
The message I keep getting is:
The expression you entered contains invalid syntax. You omitted an operand or operator, you entered an invalid character or comma, or you entered text without surrounding it in quotation marks.
The formula I use is:
strconv([field],3)

I am giving two tables and I need to create a macro that automatically updates these tables depending on the value of a Yes/No field. If it's No, it's in the 1st table TableOne, if it's Yes it automatically updates to TableTwo.
So, the best way I saw to go about is to set up an append query and then create a macro that runs it
So my tables have the values FirstName, LastName and isValid (more but keeping it short)
So for my append query, I put TableTwo in the pop up I get. Then, where it asks for the field I put it
Field:FirstName
Table:TableOne
AppendTo:[TableTwo].[FirstName]
Criteria:[TableOne].[isValid] = 1
I do this for all (it was autocompleted except the Criteria field). I tried to keep Criteria with data only for isValid but that didn't work. I wrote it for all the field names, still didn't work. Whenever I click run it says it'll append 0 rows.

I have started work on a database to track the many (several hundred per annum) projects my company undertakes. A 'main' table lists projects, their fees, their key dates, their project numbers, etc. I have created another table for tasks. Each task is assigned to a project (via the project number), and may be 'open' or 'closed'. I have separated the tasks table from the projects table as there may be several different tasks for each project. It is also good to keep a record of the tasks.
I want to prepare a report from the projects table that lists projects IF they have any open tasks.
In my mind, this means 'If a task, with the corresponding project number, is open, put a 'Yes' in the 'Tasks open' field of the Projects table.'

I generally use Cognos for my queries, so the overly user friendlyness of access is confusing me and im not proficient enough in sql to just go in and edit the code...
How do i generate a query that groups data in unique ways in the result, but does not change the data in the originating table.
For example:
I have the column tbemployment.dept . In a crosstab query i want everybody that isnt tbvoter.dept='BELLS' to be counted as 'other'.
In Cognos i would do this in the 'data definition' window for that field and use 'if (tbvoter.dept<> 'BELLS') then ('other') else (tbvoter.dept)'
How do i do this in access?

I am feeling around my database which was upgraded from Access 2003 to Access 2013. I am getting error messages and I was trying to figure out why a particular query gave an error. I clicked on "data definition" and I think it opened a new query, but it will not let me close it. The message is invalid SQL statement, expected Delete, Insert, Procedure, Select or Update. There is no way to cancel this.
I had to use the task manager to close the database, not what I like to do.
What do you do with "data definition"?

I'd like to use DLookup, DCount etc. on a SQL string held within the VBA code itself. Something like:
stSQL = "SELECT * From Contacts"
MsgBox DCount("Contact_ID", stSQL, "Deceased = False")
I'm trying to avoid creating lots of queries.

I need to ensure that the data entered into a field on a form is correct. The field contains an email address and I have a function to check if the format is correct.
If the format is incorrect I need the cursor to return to the field in that record. The form is continuous.
What event should I use?
