Merging Fields From Multiple Tables In Database Into One Field In A New Table?
May 11, 2011I'm looking for a way to combine a field from multiple tables into a single field in a new table. Because the data populating the tables is coming from an outside source, I would prefer not to change the data in the original files. I have a separate table for each year because this is the way the data is provided. The field layout is not consistent from year to year, but each year there is a field that we'll call "score." I'd like to pull the field "score" from each year's table and have it populate a "score" column in a new table along with the year of the data so that all the years' scores are in the same place. Is there a way to do this using Visual Basic + Access?

Aug 11, 2009I have 2 DataTables in vb.net. Each is populated from it's own stored procedure. Table A contains a project number in the first column. Table B also contains the project number in the first column. Table A could have many records that have the same project number, but Table B will always have just one record in it per project number. I would like to append the data from Table B to every matching record in Table A. How would I do this?

It cannot be the SalesOrderHeaderKey which will be copied also.

Data Logging Application That Stores Data In A Table In A MySQL Database?
Dec 18, 2010I have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?

DB/Reporting :: Updating Client Data Tables When Data Table On Shared Drive Is Updated?
Sep 28, 2009I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

So after the two files are merged I will have the merged file converted to PDF.
