As you see its a composite key. Now each time a new record is created i want the ConfNo to autoincrement within its ConfYear. I used a byte as its not usually more than 4. Autonumber does not work as part of a composite key i found out.
2014 1
2014 2
2014 3 etc
And revert to 1 when ConfYear input changes to 2015
Is there a simple way to do this with say, a macro, or is the only way with VBA and DAO?
I am creating a database that tracks the selling of products amongst other things.
The user will enter in an order and may delay invoicing until the customer approves the quote - at which time the order is turned into an invoice.
In the transactions table the OrderID, ProductID and CustomerID constitute a composite key.
I want to be able to view the order and change it by either deleting or adding ordered items (obviously prior to invoicing) but because the ProductID is part of the composite key I cannot delete a line item.
Perhaps the solution is to remove ProductID from the index or is there a better way?
I'm creating a database for a school. it contains the following tables: 'Students' of which the primary key is StudentID, 'Subjects' of which SubjectID is the key and 'Exams' - ExamID.
Then, I have a table called 'Results' but with no primary key of its own - just 3 foreign keys from the other tables and another field which can be left blank let's call it 'Grade'. So the Results table would have the following fields:
StudentID*, SubjectID*, ExamID*, Grade
Now, I make a form which creates a new lets say ExamID and I would like to create records with all the combinations of all of the subjects and students, ready for the 'Grade' to be typed in.This is assuming the Exam isn't based on the Subject directly.
The 'key' fields are a composite key of primary key fields from other separate tables. I have a form that generates a new 'Key 1' record and I would like to make a query that creates all possible 'Key 2' and 'Key 3' results (new combinations) while key 1 stays the same. How would I go about doing this? I know I can be done.
I cannot really give any real data as I haven't received it yet.
I have a master list of projects, with project reference number, project name, and nature of project.
I have also got a form for individuals to fill in details of project events, with date, time, name, and two or three other fields - also included are project reference and name. I'd like the name field to be auto filled when the user selects the project reference from a combo box; I think? (the list only shows open projects).
I'd did something similar some years ago in Access 2003 (I think) but cannot figure it out in the version I'm currently using 2010.
I would like to know if there is any procedure to restrict/stop auto number increment for certain number of record count (say 50), then increment by 1 for next 50 records.
I have a monitoring database, the site_ID, Date and survey_type are indexed as this uniquely identifies each survey. I am not sure if how I really link the Site table to the other three, or if it would be better if I had a Survey_ID field that acted as the link. This then gives me a few problems in how to enter the data.(Note. I havent included PK's for the conditions, frog and bird survey as yet as I am not sure which is the best way to go at this point).Site
How to assign value to a field based on the value of the same field in the previous record? Autonumber has its limitations for my purpose. Because, after I start filling up a form, I some times cancel the form filling process, and it affects the continuous numbering.
I guess the issue can be resolved by using some thing like record count facility. i.e. current' record's field value = number of records till previous record + 1.
How to exactly codify or execute the above by vba coding.
The Field Name is "SerialNo.", and Table Name is "StudentData"
I am importing an Excel file with existing data using the Import wizard to build my table. It has an ID field (CID) which I would like to keep and set to auto increment starting with the next number. Can this be done ?
Can someone tell me how I can change the increment in an existing database.
The PK is currently Auto ID with each new record currently 1001, 1002 and so on.
What I am trying to do is say starting monday the next new entry begins at 5003 versus 1003, in essence I am trying to change my first number to a 5 versus a 1.
I want to know how to reset (to start again from 1) my primary key field. As an example i have the "Customers" table with the field "customerID" as PK now i entered many values (20) then i deleted them but i want to start again and the "customerID" value starts with 21 i understand that but i want a fresh DB (i was testing things) and i want to start from 1 can i? how? i even deleted the relation between this table and the other table but no success!
Basically, we have different camera modules on which we perform a given test a number of times, giving rise to 2 tables, tblCamera which will store basic info about the module and tblTest which will hold info for each test perfomed.
The camera module has a unique ID (CameraID, the Primary key in tblCamera and foreign key in tblTest (one to many)). The primary key in tblTest will be a compound key of CameraID and an incremental number for each test performed on a given camera (TestNo). The data for the tests will need to be entered through a form, so I can build a form based on tblCamera with a subform based on tblTest (which would be in datasheet view)... What I am looking for is a way to increment TestNo in the subform, starting at 1. I have tried using
in the Default Value box for this field, which works to a point but has the curious effect of adding each number twice (as the default value for a new record seems to be added as soon as you start typing in the current 'last row')
I just can't seem to get my head around this one, any suggestions would be much appreciated...

I have a daabase that I am importing via excel. I want the entries to be numbered ex: MT0001 MT0002 etc....
I would like it to promt the user for the last number(or next number in sequence) entered, then fill in the blank records with the next increment number. The prefix will also change to so eventually the user would enter into the prompt RD0001. then autofill the 140 imported records with RD0002, rd0003... etc....
I can't really make seperate fields because the MT0001 number will become a barcode and putting them seperate causes many issues.
can this be done? Any help would be great I am still a beginner but slowly learning! Thanks!
I have inherited an Access DB that is supposed to be kept "alive" but not made much better. On a weekly basis I get an Excel CSV that I'm supposed to import into one massive table; that works just fine.
However, there is another query that takes values from a table named "New Users From Import Table" and appends them to the current "User" table.
But before running that query I have to manually update a field called "Display Name ID" with the next highest number from the User table but only the highest value that isn't in the 9000 number range.
For example, my next highest "Display Name ID" is 1144, which of course does not include the records that range between 9000 - 9008.
I had to manually enter 89 "Display Name ID" values yesterday and I know there has to be a way to update that field when I pull the data over from the temp table without having to do it all manually.
Here's the query that pulls the data into the "User" table (after I've manually entered the incremented values).
INSERT INTO Users ( [Display Name ID], [User Type], Organization, [Display Name], [Alias Name] ) SELECT [New Users From Import Table].[Display Name ID], [New Users From Import Table].[User Type], [New Users From Import Table].Organization, [New Users From Import Table].[Display Name], [New Users From Import Table].[Alias Name] FROM [New Users From Import Table];
how to auto increment one field based on the value in another field. What I have is a table with six fields. There is a foreign key assigned to each record and linked to another table. Four fields in this table are number fields indicating accordingly a number for a category, a number for a subcategory, a number for a subject for a subcategory and a number for an instruction for each subject of subcategory. The last field is the text field for each instruction. Numbers are required to be included in the report. Also, number of categories, subcategories, subjects and instructions vary by each record in the the table which this table is linked to. What I'm trying to accomplish is to have numbers in the subcategory to auto increment starting with "1" for each number in the category field, numbers for each subject field would auto increment starting with "1" for each number in the subcategory field, and numbers in the instructions field to auto increment for each number in the subject field starting, again, with "1". I also need these numbers to restart with "1" for each new record in another table.
(if the record in another table is a new/next table)and so forth..I have been looking for anything that could remotely work for me. Every VBA code I've tried is either don't work the way I need it to work, other codes making the field to continue increment numbers if the number already exists in the other field.
I'm making up a stock system for the independent jewellers I work for. Each stock pattern needs an individual code which can quickly be recognised read as tickets are often taken off the jewellery and can be mixed up easily. To this end we categorise based on two criteria:
1. Material 2. Type
At the moment these are as follows:
MATERIAL
IDMaterial 0Base and Miscellaneous 1Silver 2Gold 3Palladium 4Platinum 5Pewter
TYPE
IDStock Type 0Previously Owned 1Ring 2Pendant 3Chain 4Necklace 5Bracelet or Bangle 6Earrings 7Brooch 8Gents 9Gift, Clock or Miscellaneous
So if I had three pairs of silver earrings I want the first to be No. 161, the next 162, the next 163. If I had three Gold Bracelets I'd want them No. 251, 252, 253 and so on...Material and type are both selected form separate Comboboxes on a form.
I am attempting to update an oracle table using MS Access.
One of the fields to be updated is a primary key number field.
I'd like to use the autoincrement field to update that field.
My sql is:
Code:
Alter table testAutoNum Add column progid autoincrement (1001,2)
This sql nicely creates the new field in the table, but it doesn't start at 1001 and increment by 2; it starts and 1 and increments by 1.It is also creating an autonumber and I need it to be a number.
Composite Primary Key in Ms Access 2010. I shall try and explain my tables in detail. So my first table is "Client Database" where the field "Buyer" is primary key. This is connected to my next table "Project Database" which has fields such as Work Order #, PO #, PO Date , Buyer etc where Work Order # is the primary key. Finally "Projects Database" is connected to Order information. Now the problem is until now, I always had 1 PO # for each Work Order #. However now I am facing a situation where my client has clubbed multiple PO #'s for the same Work Order #. I need to trigger the Primary Key Violation only if both the Work Order # and the PO # are the same.
I am trying to join 2 tables with composite keys - each of them have the same 4 columns as part of its key - date/person/problem/date sent.
Table 1 has 5 columns (4 key columns + 1), Table 2 has the same 5 columns plus 1 additional column (Comments).
I am trying to match the Comments column in Table 2 to Table 1 and show the output in another table.
Currently, I've related the 4 columns in each table to each other, each relationship defined as including all records from Table 1 and only the records from Table 2 where the fields are equal.
In the fields, I have 5 Columns from Table 1 and the last column (Comments) from Table 2. When I run the query, I get all the records from Table 1, but not all of the Comments that match from Table 2 are shown.
I have an events table and a junction table that has a composite key with two fields; those are the only fields on the junction table and are FKs in my events table.
I have a form that fills in events to my events table and also fills in values to my junction table. The control source is a query of the two tables along with a couple of other reference tables for metadata associations. The form works fine... the first time. My problem is that, after I have entered an event that has my unique composite key for the first time (thereby entering a new record to my junction table), once I go to enter a second event that uses the same key, access tries to enter the record again and throwing a "3164: field cannot be updated" error instead of referencing the already created composite key.
I have the form set the composite values to the selected values on form load. Normally, I would just set the primary key to the primary key values and access would follow my logic, but in this case it always tries to make a new record.
I am creating a bridge table to get rid of redundant data. I am doing it by making a composite of the primary keys from the two tables I am bridging. The error message when I get to a certain point is "You cannot add or change a record because a related record is required in table tblMachCent." Both the numbers I am using to create this composite key are in the tables necessary, so I am not sure why I am getting this problem. Any suggestions??
