Append Several Tables From Different Databases
Sep 6, 2006
Hi All
I have started working with a database/s that was not set up by me and I am having problems appending tables from different databases.
Overview -
There was one original database set up to collect clinical data with a 'mainTBL' (health data) and a 'subTBL' (medications data) linked within the 'mainTBL'. Rather than having one continuous database the data entry person has copied the database and used a copied version for each month (where the records were deleted so new records could be entered) - so I have six databases for six months of data entry and I need to make it into one big database.
There is an ID field in the 'mainTBL' that is an autonumber (and primary key) and this has a relationship with an ID field in the 'subTBL'.
The problem -
The autonumbers in each monthly database are not unique across the six different databases (Eg the autonumber in both february and march starts at 74 so there is duplicate ID's in february/march). I have to append all the monthly databases (including the 'subTBL's) and then start a new autonumber so they are all unique and new data can then be entered. I am having trouble appending because of the duplicates and the relationship between the ID fields - what is the best way around this.
Thanks for any help in advance.

I inherited an interesting problem. I have 3700 tiny MDB files all of which contain the same table (same name, field structure, etc.), but different data. Each database has a slightly different name. It's the result of XML data mining.
I need to combine these 3700 tables from these different databases into one table in one database.
I can't see any way to automate this and as it's a one-time only project I don't know whether it's worth trying to automate it or if I should roll up my sleeves and just start apending tables.
Does anyone have any suggestions?

I need to do a join on two tables, one is in the current database, but the onther one is an another database. I am struggling with the syntax. Can anyone advise where I am going wrong?
This is the code, but it says the usual 'Syntax error in FROM clause'
SELECT za06_report_2006.wbs, za06_report_2006.cost_cntr, wbslist.description
FROM za06_report_2006 LEFT JOIN wbslist in '\ukdewgs002gdatapcdatafinancedocumentwbslis t.mdb' on za06_report_2006.wbs= wbslist.[wbs element];
All table names , variable names, and paths are correct.
Thanks for any suggestions
(I am very new to SQL)

I've currently come across the issue where an end user copied the database locally to their computer and has been using it for months and months. After fixing an issue in the database on the server and then finding that someone still had a database bug is how I figured this out. Anyway, what would be the best way for me to merge the table 1 from the database she was using to table 1 in the database on the server? Is there a way to export a table so I can then import the data? Like I said, the databases are identical other then the data.

I have a db that runs call stats (Master) this exports to several Department (Slave) Databses. The Slave db's can be accessed by any of number of Managers.
My problems (Amongst others!) is that I run the master every 15 mins and the slaves are linked to the master tables. How can I set this up so that these slaves can be updated whilst they are logged into?

I have 4 databases that share 3 tables.
Each database is used for different purposes and other tables which do not relate to the other databases.
My question is: how do I set up the back ends so each database can retrieve and enter data into the 3 shared tables without conflicts??
I know how to split each of the databases to front and back ends but how would I link them all to the 3 tables they share? Should I create one back end with only the 3 shared tables and link the separate back ends for each database???
Any help much appreciated!

Dear members,
I have two databases, Source and destination ;
strSrceDB = "C:WSS_DBRehabilitated_Water_Supply_Kulyob.mdb"
StrDestDB = "C:DBWSS_Khatlon.mdb"
I would like to append records to the destination table (Contractor_GIS) when there are no matching records in the source table (Contractor).
My code is as follows:
Private Sub CommandButton1_Click()
Dim strTemp As String
Dim strSQL As String
Dim StrDestDB As String
Dim strSrceDB As String
Dim mdb As DAO.Database
On Error GoTo ErrorHandler
strSrceDB = "C:WSS_DBRehabilitated_Water_Supply_Kulyob.mdb"
StrDestDB = "C:DBWSS_Khatlon.mdb"
'Make sure it is there
If Dir(StrDestDB) = "" Then
Call MsgBox(StrDestDB & " does not exist", vbOKOnly, "Aborting...")
ElseIf Dir(strSrceDB) = "" Then
Call MsgBox(strSrceDB & " does not exist", vbOKOnly, "Aborting...")
Else
strSQL= "INSERT INTO Contractor_GIS("
strSQL = strSQL & "System_ID,"
strSQL = strSQL & "Contractor_Name)"
strSQL = strSQL & "IN '" & StrDestDB & "' "
strSQL= strSQL & "SELECT Contractor.System_ID,"
strSQL = strSQL & "Contractor.Contractor_Name "
strSQL = strSQL & "FROM Contractor IN '" & strSrceDB & "' "
strSQL = strSQL & "Contractor_GIS IN '" & StrDestDB & "' "
strSQL = strSQL & "where Contractor.System_ID <> Contractor_GIS.System_ID;"
Set mdb = DBEngine.OpenDatabase(StrDestDB)
Debug.Print strSQL
Call mdb.Execute(strSQL)
mdb.Close
Set mdb = Nothing
DoEvents
MsgBox ("The Geodatabase tables have been successfully appended!")
End If
Exit Sub
ErrorHandler:
strTemp = Err.Description & " [Update_SystemTab]"
Call MsgBox(strTemp, vbCritical, "Contact Help Desk")
End Sub
I get Syntax Error in "Insert into" clause.
Any help on this will be most appreciated.
Thanks in advance.

We have a case where there is an append query in one database that is is updating another database table. We have moved all the tables to MS-SQL (2008) using the SSMA tool. We were wondering if it would be possible to create a new linked table in the DB where the append query is. Of course we cannot use the SSMA tool again since the table already exists on the MS-SQL server.
Normally when I try to make linked tables from Access, it wants to create a ODBC connection which we are not using.

I have a club member registration application consisting of a program database and a data database. They reside in the same directory. There is an autoexec macro which runs at the beginning. This macro has to find the DATAdb and make sure that the required tables are linked (Not all tables). If it cannot find the DATAdb and then has to make a call to the user to use a different procedure.
Now to find the DATAdb I have used the following code that works. The function GetPathAndName parses the string db.name and outputs the path and name of the PROGdb. Up to here no problems.
Code:
GetPathAndName db.Name, FrontPath, dName
Then I use the following code to get the fullpath of the last database used and thereby find the path and name of the last DATAdb. The path of PROGdb is used in place of the existing path of DATAdb to check whether the file exists.
Code:
Dim rs As Recordset, cPath As String, cName As String
Set rs = CurrentDb.OpenRecordset("SELECT Database, Type " & _
"FROM MSysObjects " & _
"WHERE ((MsysObjects.Type) = 6) AND ((MsysObjects.Name) = 'MembersTbl') " & _
"ORDER BY MsysObjects.DateUpdate DESC;")
[Code] .....
As the final step I use the table definitions to refresh links that already exist and connect tables that are not linked The code is below. But I can not get it to work. It links 7 tables instead of 16 and when tested in different folder says invalid operation and so on. There is fundamental error some place but I could not figure it out.
Code:
On Error GoTo Error_Linking
Debug.Print "TableDefs.Count="; db.TableDefs.Count
For I = 0 To db.TableDefs.Count - 1
Debug.Print "TableDefs("; I; ").Connect="; db.TableDefs(I).Connect
Debug.Print "TableDefs("; I; ").Name="; db.TableDefs(I).Name
[Code] .....

there are many threads about Table Linking but i coud not find one that answers my specific questions.
1. Can i either prevent database from linking to my tables? (or give permissins )
2. If not, can i make the table read only when linking?
3. Is there a way to confirm what databases are linked to my tables?

I have database for each location. Every location will update some information in the databases and send it back to me. In those location based databases, information will be stored in one table called "consolidate_input". I will store these databases in one specific directory and then I want to accommodate the data of "consolidate_input" into one master database having the same identical table in the database.

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.

Hi all,
I have created a dB to track assets and the implementation of new assets.
The data is located in a flat .xls file which i have imported into my dB as a flat table. I want to move the data from that table into the respective relational tables and keep the relation.
Aaargh, how do I do this? I have tried an append query but I can only append one table at a time and then I can not retain the relations for all the data.
I am including a pic of the relations.
Please help.

I have two tables I want to update...One table is a lookup table (Dates) and the other holds most of the information (History). I then have a query that finds the information i need that will be appended to both tables. One field in the query needs to update the dates in the lookup table "dates" and then the history need to get all related info.
Example:
Before Query -
(In Date Table) (In history table)
1/2/06 Jane Doe $10
1/3/06 John Doe $40
After Query -
(In Date Table) (In history table)
1/2/06 Jane Doe $10
1/3/06 John Doe $40
1/4/06 Jeff Doe $50 <---- How do I add this info, to both tables

I have a database with a number of linked tables that are linked to tables in different databases (not a back-end).for example, I have table1 that is linked to table1 in K:databasedb1.mdb.table2 linked to table2 in S:datadata.mdb.and so on...
However, recently we have moved all our databases to a new location.
K:databasedb1.mdb is now residing in O:masterdatabase
and S:datadata.mdb is now residing in O:masterdata
and so on...
I'm now in charge of relinking all those tables to point to the new location.I would do this in linked table manager one by one but we have 100s of tables linked to multiple different databases in different location.is there a way to create a VBA code that will automatically do this re-linking process?
so,
1. find unlinkable tables
2. search its new location under O:master
3. re-link it to the new location
Database names and tables names have not been changed. Just the location of databases.

I have two databases that I need to merge into one. The structure of each DB is identical, however the data is different. My original thought was to import all the tables into one DB, then use Append queries to merge the similar tables. The problem is that the main table in each DB has an Attachment field (using the Attachment data-type). After doing some research, it seems that you cannot use an Append query that references a table that contains a multivalued field (such as the Attachment data-type).
Every record has at least one attachment stored in this field, so removing the Attachment field is not possible. So my question is, if I have two identical tables, each with an Attachment field, how can I combine them into one table?
The only idea I had was to write a VBA procedure that would loop through all the records in the main table and save each attachment in a folder outside the DB, then delete the attachments. I could then merge the two tables using an Append query. Finally, I would run another VBA procedure that would load each saved file back to the appropriate record in the DB. The procedure that saves the attachments would have to write the primary key for the record they were attached to in the filename (or create a new sub-folder that is named with the primary key value), then the procedure that loads the files could read that value from the file or folder name and know which record to attach the file to.

Hello,
Firstly I would like to state that i have very little knowledge of Access databases (my job is not computer related) but I am trying my best to get a few issues sorted...
So here it goes: I have 2 tables, one large table with about 3-4000 rows(horizontal lines), and a smaller table with only about 1000 rows.
The rows in the big table contain Products (name, dates, adresses, phone numbers etc) and every product has a 'Codename' in a column-line (vertical)
of the big table. (there are about 3000-4000 products)
In the small table there exists a similar column-line (vertical) that contains 'Codenames' of the Products listed in the big table, but there are only ~ 1000 'Codenames' not the full 4000 ! The reason for this is that in the small table there exists another column-line(vertical) that for every code listed (in the small table) contains a certain specific "description".
My task is to get all the 1000 "descriptions" from the small table inserted into the Big table accordingly to their proper 'Codename'. This means createing a new column in the big table and: if the codename exists in small-table insert the description in the new column-cell, if the codename doesnt exist in small-table leave new-cell empty...
How do i do this ? :) Im guessing some coding is envolved.. and i have no clue whatsoever....
Thank you,
George P.
