I'm a student learning how to use Access for my class project (Information Technology in a Global Society), and I chose to work with databases (even though, frankly, I'm technologically challenged). I've already finished making a very elementary database (tables, form, and a macro or two), but I was wondering if there's any possible way to synchronize the material in each table in such a way that changing the information in one would automatically update information in the other.
(I have one main table, and several other sub-ones with the exact same information but only parts of the main table. By this, I mean I created a main table with every student's Extended Essay topics, along with their supervisor as another field. Each supervisor oversees an essay for several students, so I created sub tables for each supervisor with the information of only their students.) What I'd like to know is if I can keep one main table with every supervisor's information and separate tables for each supervisor -- while, at the same time, having the main table update with the information that's added to the sub-tables by the supervisors.
I considered using Relationships, but after going through the threads here concerning relationship issues...I got even more confused.
hello. can anyone help me with replica conflicts? i need to work with 10 replicas and synchronize with a master, but anyone can make changes and modify the records on the other replicas. is there a solution for that? why access doesn't recognize the changes as a conflict? Thank you all.
I am trying to create a sub-form which achieves the following.
When you select a vendor from a combo-box, only the software that is manufactured by that vendor appears in a data-sheet form view.
I have tried to create a secondary form which shows all the software and saved this. And then created another main form which has a combo-box for listing and selecting a software vendor. I have then dragged the secondary form into an area of the main form. Now i am just trying to figure out how to synchronize the two forms so that when you select a vendor, only software manufactured by the vendor is shown.
How do I make the name appearing in my combo box to change to match the name displayed when the record navigation buttons are evoked. Currently, when I use the navigation button, the form scrolls to the next record, but the name in the combo box does not change to match the new record?
I have a database that is replicated and in my attempt to synchronize a message keeps popping up "Synchronization between replicas..... and ....... failed. The field is too small to accept the amount of data you attempted to add. Try inserting or pasting less data.
The problem is I don't know what field in what form or in which replica this is referring to. Please help!!!!
We have multiple users using the same database as local copies on each of their PC's. they are entering information in specifically assigned areas and no one is overlapping in their work areas. The users then synchronize to a master database that is on the network to transfer their info.
When synchronizing we are beginning to conflict errors, and the message is hard to decipher. Below is an example:
"Update/Delete conflict: Another replica also updated this record. This record lost the conflict. Either resubmit your update or delete the conflict record."
It then shows two columns. Column 1 has the option to "Keep exisiting data" an dcolumn two has the option to "Override with conflicting data".
Technically, when synchronization happens, data of the user who is synchronizing overrides existing data in the master database in the same record(s). In that spirit, what is the 'existing' and 'conflicting' data referred to in the message?
I want to synchronize 2 comboboxes (actually 3, but let's start with 2)
On a form I have 2 comboboxes:
- CompanyType (FK fkCompanyTypeID in table Contacts) - Category (FK fkCompanyCategoryID in table Contacts)
Let's say we have companytype CT1 until CT10.
For CT1, CT2 & CT3 I want to choose a catagory, so the combobox must be 'enabled'.
For CT4 until CT10 the Catagory combobox must be disabled, so that I cannot choose a category value.
Actually I want to choose 2 catgories (2 comboboxes) for CT1 until CT3. But I think that an explanation for the example above is sufficient for me.
Both comboboxes are filled by a Select Query, and the values are filled in a separate table. (Table CompanyType (PK pkCompanyTypeID) & Table CompanyCategory (PK pkCompanyCategoryID)).
Can someone please help me on this issue? :confused:
This is very bad. We're losing data changes when we run a synchronize on an Access database.
A client wanted to use replication so he could have several people using the same database and then update everyone's changes. (It turns out that he's not used that feature.)
The client was unable to get the replica to work on his machine, so he uses the master version.
Instead, we've used replication to allow me to make changes in the database structure while he makes changes in the data. (Obviously, it would have been better to split the database in two parts, but it's too late for that now.)
Here's my process when I need to update his copy: 1. Synchronize between my master and replica. 2. Copy master to CD-R. (We're not on a network.) 3. Synchronize between client's master and replica. 4. Send a copy of master to client. 5. Open my new version of master on the client's computer and synchronize with his replica copy.
When we do that many of his recent changes disappear.
Why is that? They don't even show up as conflicts.
What are we doing wrong? Are we totally abusing the concept of replication or what??
I'm stumped. I appreciate any suggestions or thoughts.
I have a form with a text box from a table (cus. ID) and when I input that cus.ID into that text box I would like for that data to be stored in the appropriate table (customer) and also in the bridge table (customer purchases). Is there any way to input the data once into a textbox on the form and have it recorded into two different tables? Please let me know. Thanks
I am developing a small database for use in a multi-user environment: I have split the tables off and am testing with two copies of the front-end on different machines. All seems to work well except on one form.
On this form, the value of a bound control (exposed as a number of radio buttons) is used to make related controls on the form visible or invisible. I use the AfterUpdate event to trigger appropriate VBA code to accomplish this; it works well.
However if two users have the same form open at the same record (unlikely, but not impossible), and User A changes the value of the control via the radio buttons, Access will eventually propagate the change to User B's copy of the form but the AfterUpdate event will not be triggered and the form becomes inconsistent. I understand that events are only triggered when a user makes a change to a control; how can I be alerted when Access makes a change?
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.
What I have is a database setup with multiple tables in which different areas of my DC can input information simultaneously into their respective tables. I then have another database linked to it for myself to have a live view of each updated record. I would like to see all the records of each table in 1 single table (possibly just sorted ascending by time). Each table has the same Field headings but may have different qtys of records. As I will then have it linked to an Excel table to VLOOKUP from it.
I have tried Union coding but always get Syntax Error etc.
I'm using the MS Access 2010 ExportwithFormating action to export three tables to a single MS Excel 2010 workbook. The action overwrites the first excel worksheet each time instead of saving all three worksheets in a single excel workbook.
How can I export three tables into a single excel workbook.
I have created a table that acts as a header for my data and a second table that acts as line item data. What I need to do now is add a second child table that uses the line item data as its parent table and stores associated line items for each record. Is this possible?
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 some experience doing 'Update Query' using two different tables but I'm having a hard time doing an 'Update Query' using 3 tables.
I have my source table TP05XY with the fields 'Mark' 'Date' 'UTM_Edig' and 'UTM_Ndig'. Mark and Date are my primary keys (they together uniquely ID each record). I have my Observations table with the fields 'Mark' 'Date' and 'Obs_ID'. The last table is Locations with 'Obs_ID' 'UTM_E' and 'UTM_N'.
I want to update my fields UTM_E and UTM_N from UTM_Edig and UTM_Ndig. However, to do so, I have to go from my TP05XY table, through Observations table to update Locations table. Table TP05XY is joined to Observations through 'Mark' and 'Date' and Observations table is linked to Locations through 'Obs_ID' field.
I have tried a few options without success ... anyone knows how to do 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:
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
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 am currently using Microsoft Access 2010 32bit, and have one database acting as parent, with a second linked database as a client for people to work with, and the parent database has tables imported from Sage V21 via ODBC. I have used the following code as specified in other examples as follows:
one of the tables has 10k records in it, it only transfers 77 records. After manually attempting an import via the ODBC wizard it finally lets me access all 10k records.I wish to have a single button click delete and import fresh tables without worrying if all the data is coming across.Also, when manually adding a table, I am usually asked by the wizard to specify an index, but with the code above, I am not offered that option and the tables come across with no index. I am led to believe that having tables that link to each other without an index is bad, so how do I ensure an index is created?
I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.
I have an Access Table with about 28,000 Automobile dealerships across the country shown. I've joined a new/small phone contact table to this to keep up with our phone contacts with the dealership and followup efforts. When I search/filter on the dealership table all is fine. However when I search/filter on the phone contact table with a few test entries, I get nothing at all. I supposed that after joining the tables, I'd be able to do a search on the field named follow up date and find/filter today's date or other dates and locate which dealerships to contact when the correct date arrives. But nothing.
I have developed a Microsoft Access 2010 database for my client and the database is split with Front-end/Back-end, the Back-end and the database is shared on Network, The client operating system and applications for all users are hosted and consistent and the service is delivered over Citrix.
The database some times corrupt the tables record and give a permanent #Delete Error, I have attached one of the database table and the screenshot of the error,
I want to fill local tables in some application with disconnected recordset. The tables in the front end application having the same table structure as in the back end database. The front end application was linked with the back end password protected database tables. I want no connected linked tables in the front end application. How can I fill the local tables in the front end application with the back-end password protected tables?
Table 1: contains staff names and contact numbers Table 2: contains training above staff have been on or need to go on Table 3: contains pc and printer asset numbers of above staff
I used a form and entered some new members of staff in table 1. They got their auto numbers etc but when I open table 2 and table 3 those new members are not showing up in those tables. I have checked the relationship status between the 3 tables and the staffID from Table 1 is associated to table 2 and to table 3.
What's stopping the new entries from showing up in tables 2 and 3 ?
I am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?
