Modules & VBA :: Copying Records From Linked Table / Each Record Slower And Slower
Jul 30, 2015
I have an access db with a linked table (to Sharepoint) which contains about 15000 records. I have to copy those records to the local access db. To do this I have a bit of VBAcode. It works, but for each next record that is copied it takes a bit longer. When starting the program the records are copied quite fast, but soon you see it slowing down until after a couple of thousand records it just goes too slow to be usefull, meaning it would take a lot of days to copy all records.
What I now do is let it copy 500 records and exit ms-access completely and then start it again and let it copy the next 500 records. This works but is tedious as I have to do it about 35 times. Why this gradual slowdown occurs?
The VBA code is pretty straightforward.(I use VBA because I do a bit of data wrangling while reading in the values of the records)
Code:
Dim importdb1 As DAO.Database
Dim rsimportdb1 As DAO.Recordset
Dim i As Double
Set importdb1 = CurrentDb
Set rsimportdb1 = importdb1.OpenRecordset("2015")
Set rsMain = CurrentDb.OpenRecordset("tbl_import")
I've got a database with 1.5 milion orders. In those orders there are also customer information. Now i want to filter the customer information. In a older backup from my database when i run the query i takes about 22sec. But my new database it takes 2 min. (Both have 1.5 milion orders).
I haven't got a clue why i've got this problem. I've put some indexes on the table (didnt work) so i deleted the indexes from the table. I also put some relations to the tables.
But the strangest thing is that the status/progres bar in the leftbottom screen go's immediately to the end of the bar, and there it stops for 2 min, The old db does this in steps...
My operating system is winxp with sp2 And access xp
I also want to know if it is possible to get clusted indexes in access. Because i cant get the integrity in the relationship diagram. (the database isn't normalised this is because i didnt make the database)
I have a pop up form with a datasheet as a sub form. We use the up and down arrows to move between records. The problem is using the down arrow is 4 to 5 times slower than using the up arrow. This becomes a big problem when we hold down the arrow to move down 50 or more records. I believe it has something to do with the way the screen is repainted because in testing if I shrink the datasheet to show only 3 or 4 records the up and down movement is almost identical and matches the performance of the excel spreadsheet that this form was based on. Is there any fix for this?
I have my database connected to a network of ten computers. I recently switched my linked tables from a Mapped Network Drive to using the actual UNC path \computerfolderdatabase.mdb
My users have started to notice it takes longer for the database to connect in order to log in. Once they have established the connection, the data transfer speed seems to be normal.
Is this to be expected? Any suggestions to speed things up for login? Or is this the downside to using UNC?
I am developing a database and testing it with dummy data. With 50,000 records, the query process using SQL command is just OK. But if I double the total records, the query process takes longer time. The query is to make recapitulation using SUM of SQL command based on certain criteria. Any idea to make the query faster?
I am looking to copy one exceptionally large table to another. I can use VBA to copy the entire Report2013.accdb to Report.accdb while compacting at the same time. This is very fast and works well. However once it's copied I need to rename the table tblReport2013 to tblReport. None of these table are in the accdb that I am running the scripts from FrontEnd.accdb. I am working very hard to keep the data tables under the 2 GB limit, which is why linking and keeping the data separate is necessary. There is the chance that Report2013 will be on the network while tblReport will be local to the user, and may or may not be a subset of the Report2013.
I have considered a number of options: DoCmd.Rename - I can't seem to tell it a database location
I could try docmd.copyobject - and see if it keeps the file size the same or smaller then the original.
I could just write the sql statement and copy the data that way, and compact the table afterwards. The trouble with doing the transfer that way is hitting the 2GB limit, before I can compact/compress the newly imported data.It just seems odd to have to find another solution when all I really want to to rename a table and ensure the new new is still linked as a separate table.
I have linked a SQL table to my ms access database. In order to view the SQL table as read-only and still be able to update the access table I have setup a form with a subform. I know it would be a dublication of data but is there a way thru code of copying the data on the subform to my access table. I was hoping I could put a button on the form that would copy this data. My idea is after the copy is done all the information I need will be in my access table. I'm new to this linking idea and am worried I will only have half the information I need if the link breaks etc. Thanks
I am trying to help a new employee with an MS Access 2000 problem. The db was created years ago, and the main table (permits) needed some major changes. She created a new db with a table that has all the same fields as the old db, but many new ones as well. We want to now import the data from the old db's "Permit" table to the new db's "Permit" table. All the field names are correct, but we keep getting errors trying to import and export. There are approximately 940 records.
I'm currently working on a database to track and inventory documents in my organization similar to a library catalog, but with a digital archive as well. I'll need the ability to "attach" documents to records in the main inventory (though using links instead of storing it in the db) and have the documents live in a centrally accessible location on our shared server.
I will need to have this function work through a few different tables and in a few different iterations, but I'm trying to work on the simplest part first, which is attaching a thumbnail/preview of a given document to the record for that document.
I've got some VBA working well which opens the file picker and copies the file to a directory relative to the DB. It also creates a folder with each employee's ID number if it doesn't exist already (which it gets from the Windows log in) and adds "Copied_" to the front of the file.
Now I'm trying to get the VBA code to interact with the record. Presumably I need to tell the form button I'm using to launch the VBA code to pass the primary key of the record being displayed to VBA. Then, at the end of the VBA code I need to take that value and find the record again from VBA so I can update the MediaThumbnailLink in the original record.
Does this order of operations make sense? If so, how should I go about passing these values back and forth and writing the new link value?
Here's the VBA I'm using so far...
Code: Option Compare Database Public Sub GoCopyThumbnail() Dim fDialog As FileDialog Set fd = Application.FileDialog(msoFileDialogFilePicker) Dim varFile As Variant Dim LUser As String
I'm using Access 2007.I have 2 tables that are identical in structure.The tables are called [Workorder Parts] and [Workorder Parts Temp]. They both have the same structure:
[Workorder Parts] has 128 records in in and [Workorder Parts Temp] has 28 records in it that are a small subset of [Workorder Parts] therefore, the contents of the key field column in [Workorder Parts Temp] is the same as in [Workorder Parts].I tried the following SQL but get an error message saying "Cannot Update "WorkOrderPartID" Field not updateable":
DoCmd.RunSQL "INSERT INTO [WorkOrder Parts] SELECT * FROM [Workorder Parts Temp]"
My aim is that I want all of the records from [Workorder Parts Temp]to be copied to [Workorder Parts] and have their "WorkOrderPartID" fields correctly updated with a new value...
is there an easy way to copy the current record on a form when clicking a command button such that a snapshot of that record is copied to a table for archiving purposes?
the table has about 120 columns so it is cumbersome to write an Insert Into sql statement within VBA code.
what i am attempting should be quite straightforward...i just want to take the current record in its entirety that is from a single table and append it to another table of the same structure.
It basically is used to create, manage and track Customers, Parts, Work Orders and Suppliers, payments and employees.You simply create a Customer and then create a Work order that contains a list of parts and labour items.
What I want to do is to create a "Kit" of parts so that the user does not have to select each part individually when they create a Work Order. For example, if I use a mechanics workshop as an example, the mechanic may sell his "Signature 1916cc Engine" that consists of 40 different parts and some other items such as labour and other services. In this scenario, instead of the user individually selecting 40 different parts, all he needs to do is select the Kit called "Signature 1916 cc Engine" from a drop down list and all of the 40 parts and other items would automatically populate the correct Work Order Parts/Labour tables.
I would also like the user to be able to select another "kit" that would either replace all parts and labour records or append to what is already there.
I have changed the form called "Workorders" to have 2 buttons. One called "Load Kit" the other called "Save Kit".If the user presses "load Kit" a form will be displayed that enables them to select a "kit" from a list and whether they want to replace all of the existing parts and labour records or if they want to append to the existing records.
In order to create a new kit, the user can simply manually create a new work order by individually selecting each part and labour item and then pressing the "Save Kit" button. The user will then be asked to provide the short name of the Kit and the long description (I have created table called tKit). The new kit will then be saved.
It appears that the "Entered by" field that is linked to the Employee table must not be blank other wise the Workbook is NOT saved....I have tried to figure out why this is happening but can't!
The Work Order Parts are stored in "Work Order Parts" and the Work Order Labor is stored in a table called "Work Order Labor". I have created 2 extra tables called "tKitWorkOrderParts" and "tKitWorkOrderLabor" that I assume will contain the items that make up the kits..
In a situation where I imported an excel file with so many columns and split them into two temp tables and they are linked using a key.
the data has a fixed part lets say
Field1....Field2.....Filed3.....Field4...then Field5.....Field6.....Field7....Field8 is the same data range as Field9...Field10...Field11...Field12. I would want to split this data into multiple rows like this
Field 1 Field2 Field3 Field4 Field5 Field6 Field7 Field8 Field 1 Field2 Field3 Field4 Field9 field10 field11 field12 and so own...
I am building a simplified re-order point system - if inventory position drops below a certain level (the yellow level is this case) one or more purchase order lines has to be created in another table.
I have one table with the following field and data:
ItemId Red Yellow Green Multiple Inventory position 0001 10 30 50 5 45 0002 5 40 47 5 23 0003 11 20 30 10 5
I would like to generate new records (in another table) based on the above fields and three records.Basically the end result should look as the following:
The logic is quite simple - if inventory position is less than the yellow value new order lines should be created in multiple qty (based on the multiple field) until the aggregated value (in table 2) is above the green value.The priotization value should be based on the start inv (in tbl 2) compared to the values in red, yellow and green in tbl 1.
I have two tables. TableA and TableB They both have the same columns.
I need a query that will look at the diferences between TableA.Column1 and TableB.Column1 and copy whatever TableB.Column1 is missing from TableA.Column1
So I want it to copy over the entire record based on what TableA.Column1 has the TableB.Column1 does not have.
I'm using access 2010. I want to put some code behind a button that will allow the user to add selected products in a listbox to which ever operation is selected in a combobox by creating records for each product / operation combination in a third table:
I have a form with a combobox on top that allows the user to select the operation for which they want to add products. There is also a listbox that displays all records in tblProducts. The user can select one or more products and then the idea is that they can then press a button that will use the selected record IDs from the list box and the record ID from the combo box to create new records in the many to many table.
I have two tables, table A and table B. Table A is a master table where it contains various values. I want to do it such that if user keyed in value X and value Y into Form B (linked to table B), it will check Table A for value X and value Y. If the values matched, it will display a new value (value Z) that is taken from Table A into Form B.
If IsNull(Me.txtValueX) Then MsgBox "Please type Value X", vbInformation, "Value X Required" Me.txtValueX.SetFocus ElseIf IsNull(Me.txtValueY) Then MsgBox "Please type Value Y", vbInformation, "Value Y Required" Me.txtValueY.SetFocus
[Code]...
I am stuck at this part where i am not sure how to retrieve value C out.
I am rebuilding an application for a client and I have an Access table that I am using as a temporary table. Once the user is done entering information into the temporary table through a form, the user presses an update button that appends the records using an Append Query in Access to an SQL Server Table.
The following error message occurs:
"ODBC -- insert on a linked table 'linked tblname' failed.
[Microsoft][ODBC SQL Server Driver][SQL Server] Explicit value must be specified for identity column in table 'linked tblname' when IDENTITY INSERT is set to ON. (#545)
I am using a form, subform combination to record a bill with many details. The bill summary is posted into a tbl_TransactionsMain table in SQL Server using the ADO AddNew method. The PK for the tbl_TransactionsMain is then entered into the temporary table in Access. When the temporary table records are appended into tbl_TransactionDetail the error message occurs.
What is also interesting is while typing out this post I thought to test the error by manually trying to run the query. The query worked like a charm! :confused: When the orginal error occurred off of the form I tried to run the query manually and it failed. I am guessing that this might have something to do with the ODBC timeout.
I think SQL Server/ODBC connection is not liking how I have a set of records in an Access table with foreign key numbers assigned when I am attempting to append the records. I am new to SQL Server and any ideas are most appreciated! :)
I have a basic database design, well I think so anyway. It only has two tables:
1. tblClientInfo 2. tblNotes
Basically each client has multiple notes/comments that can be linked to its record, hence the tblNotes table. The two tables have a one-to-many relationship, being that each customer can have many notes.
I then have two forms:
1. Claims Loss Form 2. tblNotes_DatasheetSub1
So I can enter multiple notes for each customer. The problem I am having is with the report output. It wants to print every note (record) that is linked to the customer. I just need it to print the most recent note for each customer (It would save a lot of wasted paper).
Example of a print out of what it is doing:
John Doe - 123 Easy St - Notes 1 (Most Recent Note) John Doe - 123 Easy St - Notes 2 (Previous Note) John Doe - 123 Easy St - Notes 3 (and so on...)
It is printing duplicates of the same customer by adding the additional notes for that same customer on a new line.
How can I tell it to only print the customer one time in the report, and most importantly, to only use the most recent note that is linked to the customer?
I tried using DMax("NoteDate","tblNotes"), but this only returns one customer with one note. I need it to do that for each and all customers.
I have successfully ran a subquery (two queries with one linked to another) by following detailed instructions from this page I found: [URL] .... It works, but the problem is it only shows the latest date for each note, not the actual contents of the note. I feel so close with this option, but so far at the same time.
The TOP n records per group looks promising that I found here: [URL] ...., but I honestly don't know how to implement it correctly in my SQL. I am very much still learning Access and apparently have stumbled into something that is much more complicated than I had originally imagined. I just assumed I could filter the duplicates out, or tell access to print the last or most recent note record for each customer.
I created a database that performs certain functions ("functional database") and I want to archive the changes I make to that database's structure in a central repository that is nothing more than another database ("repository") that I will create to track all of the revisions made to the 80 or so databases within my department.
I would like to create a link on the main form in the functional database that will, on click open the specific record in the repository database that refers to the revisions previously made to the functional database.
I am getting the error RunTime '2105' You can't go to the specifed record.
Just converted my test database to read from a sybase linked table rather than the development local table. It reads fine but the new record button now gives the above error. I presume I need to code myself a new record function . . .
Is this what I have to do, and if so, what's the best (and quickest!) way of going about it?
I am having difficulty deleting records in a linked DBF (standalone) table. The table links fine. I can run a delete query and the records appear to be deleted when I view the table from within Access. However, when I view the table outside of Access, the records that I thought were deleted are still there. The only way I can actually delete the records, is to import the table, delete the records and then export the table as a new DBF.
Can someone tell me why deleting from the linked table isn't working?
I have done everything I can think of to remedy this, but I can't figure out why this is happening. I have a linked table from excel that contains 5 fields for each record. I have a table in access with matching records and 20-30 fields. The linked spreadsheet is used when adding records. I have a query that queries both tables to get all data from both and a form based on that query where others can pertinent data for the records resulting from the query. My problem is that when I open the form the new records that were added in the linked file are there but all the fields from the access table cannot be updated. I have looked every place I know to look for record locks, read only options, everything I can think of why i cannot update these records and I am coming up empty. I checked my join properties and selected the only one that actually displays the linked records when the query is run (not sure the name of the join but it's #2 of 3 join properties options (in Access 2002). maybe I am just overlooking something simple? Do you have any ideas what I can do here?
