Adding Columns To Tables
Feb 14, 2006
Background info: I have created a database that consists of 22 tables that contains hundereds of electronic components seperated by type. In each table are columns for evey project so that i can determine what projects each component is used in.
Everytime there is a new project i need to add the new column to every table. Is there a way to add the column to every table in one step rather than having to do it seperately for each table? Every table set up the same, same number of columns and column titles and everything.
Thanks

Hi..I have three tables A ,B and C, which have fields A,B and C respectively.
I want to do that following default calulation
A.a=B.b+C.c
meaning adding two columns of different tables and storing it in a third column.
It works for me in the forms but I want to do that in the table.
Is there any way to go about it
Regards
Rahul

My database has three tables with many columns. The three tables are identical in the names of their columns.
I want to copy all columns from all three tables together into one single table, giving the respective columns prefix table1-, table2-, table3- since the columns would otherwise be indistinguishable.
I already tried to search the board for "table columns add prefix".
I use Access 2010
I managed to copy all columns together into one table through design-view, but cannot figure out the "add prefix" step.

I have to add the row data in two columns together. I used
val([COLUMN 1])+val([COLUMN 2]) and it works unless one of the columns has a zero in it. For example if column 1 is 25 and column 2 is NULL it runs the query but puts a #ERROR in those rows. Please help.

Hi guys, Excuse my novice questions.
I have a query in which i did two things: defined a Column "Line Item Cost " as Sum ( using the dropdown in Design Grid of the query).
Then i calculated another field: Expr13 which is:
Expr 13: Sum([Line Item Cost]+ [Change Request Total Cost])
So, If Line Item Cost = 1363000 and Change Request Total Cost = -40000, then
Expr13 : 1363000-40000 = 1323000, but i am getting the values: 1283000(Somehow the value is getting doubled before addition)
Please look at the attached Document.
Please Help!
Thanks,
Kon

Hey,
How can I add an aggregated column to an existing query?
For example:
I have 3 fields (a, b, c), each holding numbers. I want to add a fourth field which will average or use any other aggregated function on the 3 fields (but not by doing it manually).

I have a sharepoint list linked into my access database and every time when I work with queries and try to add up them up it causes the information to display in a text string. What to do in order to resolve this issue. For example, instead of $1,000+$5,000=$6,000 it will show 1,0005,000 as one string but not add them up.

Hi
I have 120 tables, each with the same name except 2 identifying characters at the end eg pc_dist_ab, pc_dist_al
Each table currentnly has 3 columns.
I would like to be able to add 2 additonal columns to each table with one query and was hoping an alter table query where the table name matches pattern would have worked but evidently not.
Is there a way to build some sort of dynamic query to add extra columns to these different tables at the same time?
To save another post I guess Once this is done I would then like to create 1 main table by creating a new table and appending all the files together- again I would prefer to be able to run this once.
I'd appreciate any help/thoughts as to whether this can be done?:confused:
Thanks

In the tutorial listed here: [URL]....
It states after opening the database in Datasheet view :
In the Navigation pane, double-click the table in which you want to create the lookup column - this opens the table in datasheet view.
On the Datasheet tab, in the Fields & Columns group, click the lookup column.
And it show you some icons.

I coulnt figure out how to reply to a reply. This is a follow up question to a previous post.
I can now create a new column in my access db through my web form.
Here is the script:
ALTER TABLE FAQ ADD City varchar(30)
this adds a new column called city.
Here is my problem:
Every time a user asks a question, that question will be in the new column created.
I need the newly created columns to have unique names.
I tried creating a form with a text file (to simulate where they type in their question) then post to post.asp.
post.asp holds the script.
I replaced city with ::T1:: (the variable of the text file), but got an error.
Creating columns dynamically is worthless unless there is a way to make the column names unique.
Can anyone shed some light on this problem for me?
Much appreciated
Mike

I'm trying to make a database to track inventory or several items. Basically, I have four tables:
1) RawMaterialList - includes a list of all raw materials.
2) PartList - includes a list of all finished product using said raw materials.
3) RawMaterialRecieving - contains details from each packing slip of incoming raw materials.
4) ShipmentRecord - contains details of daily shipments.
Each of these tables is fed by a form of the same name. I should note at this point that I basically taught myself how to use Access and I imagine I'm in the dark about quite a few things it can do. I've made several databases over the last few years, but I'm stumped at this point.
Here's my problem. In the form RawMaterialReceiving, I have several fields aside from basic information:
1) Item - a list of of raw materials from table RawMaterialList
2) Description - also dependent on info entered into table RawMaterialList
3) Quantity
But, I have 12 of these instances.
Item1, Item2...Item12;
Description1, Description2...Description12;
Quantity1, Quantity2...Quantity12.
My problem is I want to add up the quantities of each raw material and I'm not sure how to go about that. Lets say on May 13, I received 15pcs of Part A and 20pcs of Part B. I enter this information as Item1 and Item2 respectively. On May 14, I received 30pcs of Part B. I enter this information under Item1. Now I want to add up all of Part B (50 pcs). But Part B has one value listed in the field Quantity1 and one value listed in the field Quantity2.
Example:
1st Entry:
May 13
Item1 = PartA Description1 = PartA's description Quantity1 = 15
Item2 = PartB Description2 = PartB's description Quantity2 = 20
2nd Entry:
May 14
Item1 = PartB Description1 = PartB's description Quantity1 = 30
How do I get it to add up Part B to get 50pcs?

Ive been converting .xls files to Access database files. I would like to use ACCESS to develop the Reports but the client wants the Reports to look like those in EXCEL..eg. where you have lines between rows and columns. If I could give my Access Reports the same look and feel, I could wean these guys off of Excel and into the wonderful world of relational models.
Does anyone have sqlcode or tricks I might use to create the Excel 'look alike' report in Access?
thks in advance...and I will sum.

I am new with Access and I am setting up a data base that will have 16 tables and each table with have over 3,000 customers. The reason for 16 tables is that we will be inputting information on a monthly basis for each of these customers (12 of the tables) and I also have 4 tables that will be perfomring different "tasks" for each customer (one is just to keep the notes we make for each customer, one will be to show any billing done, one is going to be a summary of the entire year along with some additioanl information not entered elsewhere and the final one is our customer information table).
The customer account number is the primary key for all of my tables.I want to know how I can add a new customer (either using query or form) at one time that will populate all the tables. Right now I have everything set up as tables but I can set up queries if need be.

I am trying to add calculations to queries based on columns in the query... it seems to randomly expect 'Expression' or 'Group by' as column types, and Im having to create 3 sets of queries following on from each other to de-dupe data and allow filters on calculated values.
Also I've got a function which turns a date into a quarterly cohort, e.g. Oct 2013 -> 20134. I use ot on a lot of dates. I created a VBA function, CohortQ used as follows in queries:
Cohort: IIf Year([InputDate]) < 1990 or Year([InputDate]) > 2020, 0 CohortQ([InputDate]))
In the VBA, InputDate is defined as a date
Code:
Function CohortQ(InputDate As Date) As Integer
If InputDate = 0 Then
CohortQ = 0
Exit Function
End If
[Code] .....
But when I run it on a date field, it gives me a data mismatch error. I can't step through as it's working on 600K rows.
If I put the function into the query,
Cohort: IIf Year([InputDate]) < 1990 or Year([InputDate]) > 2020, 0 Year([InputDate])*10+DatePart("q",[InputDate]))
it works.

So the database this user was using was made in Office 97. The query to sum two different columns in two different queries worked fine. Then we upgraded her to Office 2003 and converted the database and it no longer worked.
Here is what I need to do:
In total query there is a sum of account and sum of extended column that sums everything in the account and extended columns from table1.
In total a query there is a sum of account and sum of extended column that sums everything in the account and extended columns from table2.
In my grand total query I want two figures returned...one will be the sum of account columns from both total and total a queries. And the other figure will be the sum of extended columns from both total and total a queries.
I have tried this numerous different ways and always get the same result...a blank returned in the grand total query. From some research I've done this could be because one of the tables/queries frequently returns no data?
Thanks for your help!

I am using Access 2007 on my front-end and SQL Server 2014 on the back-end. I have a table of Car Dealers and a table of contacts at the dealerships. These tables are SQL tables. The user can select a dealer and then see everyone that works at that dealership. When they look at this there is a field called Email. This is a hyperlink that they can click on to open Outlook and send an email. The table called DealerEmails is an Access table. My table layout is:
Dbo_Dealers
------------------
ID (PK)
DealerName
DealerAddress
DealerCity
DealerState
DealerZip
DealerPhone
ModifiedBy
ModifiedDate
Dbo_DealerContact
---------------------------
ID (PK)
LastName
FirstName
Postion
DealerID (FK)
ModifiedBy
ModifiedDate
DealerEmails
-----------------
ID (PK)
DealerContactID (FK)
Email
ModifiedBy
ModifiedDate
Now I'm trying to write the code to add a new contact. My code works but I need to obtain the AutoNumber from When I add a new record to the table dbo_DealerContact. My code is:
Code:
Option Compare Database
Option Explicit
Dim adoDealerContacts As New ADODB.Recordset
Dim daoDealerEmails As DAO.Recordset
Private Sub cmdSave_Click()
[Code] ....
I tried to add Me.Dirty=False, but this still returned a value of 0 into my variable intDealerContactID.
I also tried moving intDealerContactID = .Fields("ID").Value outside of the With block.
I'm aware that there is a command in SQL @@Identity. But I'm unsure how to use it in this context.
Is there a way to get the primary key from dbo_DealerContacts so I can insert that into my Emails table?
