I'm looking into storing query data in temp tables for my reports run better. From what I'm reading, it seems best to have the temp tables in a separate db, and to break the links to avoid bloating of the FE database. I'm unsure how to do this with VBA, especially since my temp database will be password protected. When do I break the link - when I close the FE database?

View 3 Replies View RelatedAll using access 2010. I have a multiuser database that I feel would benefit from splitting into a backend with multiple user frontends. My problem is that there are tables from make table queries processed every two weeks that all users need access to. As far as I know; you can not put a table in the backend that you will delete and remake or a temporary table and link to it in the front end. Is there any other way I would be able to split the database and have temporary tables linked from backend to frontend that I am not aware of? Is there another way to creating temporary tables and tables from make queries? This database has 9 users and counting and really needs to be split. r
View 14 Replies View RelatedI have encountered an issue when I was inserting a string (with newlines about 176 characters) into access table. This field in access has the data type TEXT and it was truncated after the insertion. It is strange because I have three other fields with the same format and no truncation at all. May I know what could be the reason and how/what is the recommend data type for storing long text?
View 3 Replies View RelatedHere's the scenario:
I create a temp table structure, which works fine.
I create a recordset from SQL pulling data from a DB2 connection. This works fine.
I want to put the entire recordset result into the temp table.
I have a working means of doing this, but it is very inefficient and leaves the user staring at an hourglass for a minute or two.
What I am currently doing is iterating through each record of the recordset and appending it to the temp table. Desired results, yes, but takes way too much time.
Is there any way to simply 'dump' an entire dataset into the table, instead of on a record-by-record basis?
Here's some code from how I am currently doing things:
Set cmdP1 = New ADODB.Command
Set cmdP1.ActiveConnection = cnnP1
cmdP1.CommandText = "SELECT DISTINCT distribution_id FROM " & sDB & " ORDER BY distribution_id"
Set rstP1 = cmdP1.Execute
Do Until rstP1.EOF
With rst_Temp
.AddNew
.Fields!distribution_id = rstP1!distribution_id
.Update
End With
rstP1.MoveNext
Loop
Any help will be most appreciated! Thanks!

I understand the conventional wisdom of not storing calculated values on the table, but I have a need to do do so. On my Input Screen I have a generated Certificate # derived from 5 single value fields keyed onto the screen. This certificate # is unique to those 5 single-value fields which should not be repeated. I want to store it on my Table as the Primary key with "no duplicates" so that if a keyer keys the same 5 single-digit values , thus creating the same Certificate #, he will get a MsgBox back telling him he cannot add a duplicate entry.
attached is my table and Input Screen.
I have an application in MS Access that contains some forms and reports. I want to be able to show pictures on the forms. So I am saving images on file system and storing links to those images in MS Access tables so that they can be retrieved and be shown on the forms. Can someone throw light on the effects of this approach on performance of the application (especially vis-a-vis the approach of storing images in the Access tables as OLE objects)?
Would appreciate if responses can be directed to my email-id Satya_Nadiminti@infosys.com
Thanks,

I know that as a general rule one should not store calculated values in a table, but if I need to include such a value on a number of forms, and calculating that value involves manipulating an ADO Recordset, does there come a point where the performance hit outweighs the design "quality"?

Currently trying to build a database for customer management and order placement/tracking. Want to set a couple of rules so that if I for instance click yes of billing and shipping address the same that the database will automatically fill the shipping address with the data I inputted for the billing address in the same table.
The other issue I can see I'll run into is, I want to be able to select one of the company ID's (made up of a three letter abbreviation of the full company name) in the product ordering table and it will automatically fill in the rest of the customer data (phone, email, address etc) data into that form.
I have 2 identical database in terms of structure but it differs in data.
Basically I would like to import data from subDatabase to mainDatabase and ensuring that there are no duplicate records.
I have used the "link to datasource method" through importing the tables to have the "updating" function.
However, this method also means that the records in mainDatabase are also imported over to subDatabase which I do not want.
Is there a method to ensure that the records are shared/update one way only? (i.e. import from subDatabase to mainDatabase and not main to sub?)
I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?
I have being playing with ms access but I really don't know much about it or databases in general.I have created a very simple database to gather twitter following/followers data for research purposes.One table (table01) has a field for the "boss" user (=the user who I gather data for), another field for "client" (=bosses followers or friends).Both fields are numeric and contain the users id's.In order to distinguish if the link is follower or friend there is a third field, called type which can be either 1 (=follower) or 2 (=friend).So the data would look like this:
boss - client - type
12345, 67890, 1
12345, 54321, 2
If user with user id 12345 had a follower (type 1) with user id 67890 and a friend with user id 54321...In order to avoid getting duplicate rows I also added a unique identifier which is of the form boss_id-user_id-type.So the above row looks like this:
12345-67890-1, 12345, 67890, 1
12345-54321-2, 12345, 54321, 2
That works just fine.For several reasons I also needed data of the form source - target.So I also made another table (table02) of this form.
67890, 12345
12345, 54321
...
In table 2 you don't need the "type" field since the position of the user id shows the type of relationship.Still, you need a unique identifier in order to avoid duplicates, so I added on with the form: source_id-client_id..So table02 lookes like this
67890-12345, 67890, 12345
12345-54321, 12345, 54321
...
Both tables also have a date/time stamp for each line.As you can see, table01, having also a type field is bigger than table02.The problem is when I try to append data, exactly the same data in both tables.Appending data to table01 is ok, while appending data to table02 (which is smaller, having one less field) takes a really long time, maybe 10 times as long as appending data to table01.To make sure that no query's are causing the problem I have tried first creating temporary tables with the data to be appended, no duplicates, nothing that would cause the database to make extra calculations and used a simple update query with no filters to append data.Still I get the same result, table02 takes a very long time to finish while table01 finishes in no time.
I have split database (B/E is in the SharePoint library, F/E has users on a local PCs). Sometimes, when I update/add data (does not matter if it is via form or directly in the table) it looks OK, but when I re-open the database, the data are gone.
Problem is that I cannot catch the moment when data were not saved (sometimes data are saved, sometimes not). I can point out this: if I re-enter the missing data, primary key continues subsequently, it looks like the data have never been entered. I tried to use script
Code:
If Me.Dirty Then Me.Dirty = False
on "On Close" form event, does not work.
B/E is linked by VBA code and it looks OK (no error, Link Manager shows correct path). I suspect interrupted connetion to the SharePoint but I don't know how to check it. I implemented VBA script co keep open connection to the SP but the issue persists.
I am doing a project where we are collecting home owner data and information on all the dogs in the household. The data for homeowner has an autonumber primary key because no field is unique or has been consistently collected. I am struggling to link the data for the dogs to the owners because an autonumber primary key will not work since not all homes have dogs. I need to have this set up so that people who are not tech savvy can look up each homeowner (or dog) and get the dog (or home owner) information. And to make things even more fun we need up to 15 potential dogs per household each of whom will have 18 different pieces of data collected.
It looks a little like this (and you can see my not matching ID issue):
Homeowner table
ID First Name Last Name...........Total Dogs
1 Max Maximus 5
2 Min Minimus 0
3 Mus Musculus 1
Dogs 1-5 table
ID Date Dog 1 Name Dog 2 Name .......Dog 5 Name
1 (Max's) 4/11/14 Bobby Billy Betty
2 (Mus's) 4/11/14 Jojo

i have 4 supplier tables with identical field names but different databases in sql.I want to have them all in one table and only want the information for reference i do not want to edit any of the data.I need to create a new primary key number for the complete table. The data will need to be refreshed as the data comes from MMS Sage looking at company PLsuppliers.
I have tried a linked SQL union view- but this has no primary key.I need to keep the Primary key consistent as the data saved in other tables will use this field.The overall goal is creating a Purchase order system and this list will be my complete supplier list.
I have a form displaying the 11 fields of the parent/primary table using a selection from a combo box. I am using queries and vba code modules respective to form, combo box and command buttons. I have initial code that uses the two fields from the combo box selection to append same to a new parent/primary archive table. I now want to add to the append SQL the remaining fields to the parent/primary archive table. When I add the second sql string for the remaining fields to the same procedure and execute I keep getting 'null in primary key'. If I copy the primary record and paste same into the archive table it works.

In my Membership Database (Access 2010), I have a Table entitled [Foreigners] in which are stored the names of prospective members of the organisation and the name and ID of the Interest Group they are proposing to join.
When a formal Application to join is received their personal details are recorded using an Entry Form related to the main [Mail List] Table.
The current procedure then is to manually delete the entry from the [Foreigner] Table and finally to record their Interest Group data using another Entry Form entitled [GroupMembers]. This relies on an operator remembering to do the necessary.
It occurs to me that this process could be automated. I wondered whether it could be entirely automated or would be best effected with a button on the main Entry Form, such that on completion of data entry of personal details the button would be activated to do the necessary deletion and addition.
The [Foreigner] Table is an entirely stand-alone table, having no relationship with the other concerned tables. The only common factor will be the Member Name, which in the main table is a concatenation of First Name & Surname..
I want a Text Box Query on my form to display the Status, Workshop, Time, Enrolled and Limit. The problem is these values come from two different tables and the Enrolled value comes from a single field that contains the different workshops.
What I mean is: In Table[Attendees] a row contains a customer's Number, First Name, Last Name, Workshop and Phone Number. The workshops vary for each customer so one row on the table could have John Doe attending Cover Letter Writing and the next row could have John Smith attending Resume Writing. What I want is to be able to count the different workshops within the Field[Workshop] and total them and then display the total in a Text Box Query. I have a Text Box Query set up displaying Status, Workshop, Time and Limit as these values all come from Table[Workshops].
So basically I need to Query to also display a result that is the Total for each workshop from Table[Attendees] and display the total for each workshop in a Query with data from Table[Workshops].
Here is a link to an Example Database [URL] ....
I'm trying to avoid putting things on different reports and the like because the people using this are basically computer illiterate and if they have to click a button (no matter how well labeled) they won't do it and the information might as well not exist.
And if there's a better way to do it, I'm all ears. The only thing is, I have to update these workshops month by month. Since they are dynamic, I want to avoid creating separate tables for each workshop.
I have created an Access 2000 Db, and have gone through the motions of splitting the Db via the Splitting Tool. Since I have done this split, I have added forms, queries, and reports to the Front End. I have left the Back end table structures alone.
This is where my problem comes into play. To enter data into the Db, I use the forms. After splitting the Db, I assumed that the data would be stored in the tables in the BE. An issue had just presented itself and I went into the BE table structure to add a field to a couple of the tables, and when I opened the BE table in the datasheet view, I noticed that there were no records. I then became curious because when I run my reports and queries, the information is present. So I opened the FE tables and what do you know, all the data I have input since the split is housed in the FE tables.
I already attempted to Update the Table Links, but that did not solve the problem, and the data is still in the FE.
Can someone, anyone please help or offer some suggestions on how to resolve this dilemna.
Thank you in advance,

So I have two tables,
table1: (company_name, company_code, year_month, rating)
table2: (company_name, company_code, year_month, asset, debt, equity,...)
What I would like to do is to call up all the data in table1, and then call up (asset, debt, equity,...) from table2 where the company_code and year-month are equal. What do you think is the best way to do this? Keep in mind a few things:
1. I'm dealing with hundreds of thousands of data lines
2. I may need to get more data similar to table2 in the future and call it up in the same way
I thought I should create a primary key "company_code-year_month"for both tables, but that method doesn't seem like a good one, and if I were to have another table, will have to create the same primary key for that table as well?
I inherited a database that has two tables that are structured identical; one called tblcurrentdata and the other called tblpriordata. The user wants a report or export query that only shows records that has differences between prior weeks data and the current weeks data. The tables have 12 fields of data in a record per quote number. The user wants a query or report to identify the QuoteNum and any changes between the prior and current records. The table structures are as follows:
Code:
tblCurrentData/tblPriorData:
QuoteNum
CoName
State
ZipcodeNo
priorityColor
[code]...
QuoteNum 12345 field 5 (prioritycolor) changed from red in the prior week to green in the current week and field 7(POC) changed from Scott in the prior week to Jonson in the current week.QuoteNum 23451 did not have any changes therefore does not need to be listed in the query/report Unmatched query doesnt work because it does not compare multiple fields. I tried to structure a union query and use <> in each field but got too tedious and didnt give the expected results.

View 2 Replies View RelatedI have to make a Costing System but for that I need to enter our Expense details in database according to Fiscal year and months.
I need a table for Fixed expenses and one for Variable Expenses and then I need one or more Forms to update data in those tables. Now I've created a table with Fixed Expenses. I have to update Year and Amount in that. Now it is only letting me one entry per Expense.
I want multiple entries for one Expense say 'Advertising' for different years. I'm thinking may be I need to make more than one Table, may be one for Expenses with ExpenseID and other for Years with Year and YearID and the third one for Amount with columns Amount, Method of Payment, Date and Notes. I did tried this but I think I'm not creating proper relation may be because its only updating for one year.
