I store all the hourly & monthly data for a product on our SQL Table, could you through me your suggestion on how to show the all 24 hours data on the to the table/repeating table. I am able to populate all other data on to the form for the product that the user selects. But I am unable to show all the 24hours on the table. I tried repeating table as well as general table to pull the data from the SQL DB.
Does any of you come across the task like the above please guide me with your valuable comments. Thanks.

I am very new to MS Access and I don't even know how should I start to approach for the solution.
I have a Table 1, that contains Project No., Part No. and Quantity of parts.
Now I want to transfer this data on button click to two different tables.
Table Order and Table Parts.
Table parts is a sub table of Table Orders
When we add project Number to table Orders, then we get auto-generated ID then based on that Unique ID, Table Parts is linked to it.
As we get ID from Table Orders, we need to create entry into table Parts with that ID that will contain Part Number and Quantity.
Can you please help me this?
I tried creating an append query but its just adding Project to Table Orders, not doing anything with Part No. and Quantity.
I have a list of unique customers who have made transactions over a year (Jan – Dec). They have bought products using 3 different methods (card, cash, check). My goal is to build a multi-classification model to predict the method pf payment.
To do this I am engineering some Recency and Frequency features into my training data, but am having trouble with the following frequency count because the only way I know how to do it is in Excel using the Countifs and SUMIFs functions, which are inhibitingly slow. If someone can help and/or suggest another solution, it would be very much appreciated:
So I have a data set with 3 columns (Customer ID, Purchase Date, and Payment Type) that is sorted by Purchase Date then Customer ID. How do I then get a prior frequency count of payment type by date that does not include the count of the current row transaction or any future transactions that are > the Purchase Date. So basically I want to do a running count of each payment option, based on a unique Customer ID, and a date range that is < purchase date of that training row. In my head I see it as “crawling” backwards through the transactions and counting. Simplified screenshot of data frame is below with the 3 prior count columns I am looking to generate programmatically.
Screenshot
This gives you the answer as a list of CustomerID, PurchaseDate, PaymentMethod and prior counts
SELECT CustomerID, PurchaseDate, PaymentMethod,
(
select count(CustomerID) from History T
where
T.CustomerID=History.CustomerID
and T.PaymentMethod=History.PaymentMethod
and T.PurchaseDate<History.PurchaseDate
)
AS PriorCount
FROM History;
You can save this query and use it as the source for a crosstab query to get the columnar format you want
Some notes:
I assumed "History" as the source table name - you can change the query above to use the correct source
To use this as a query, open a new query in design view. Close the window that asks what tables the query is to be built on. Open the SQL view of the query design - like design view, but it shows the SQL instead of the normal design interface. Copy the above into the SQL view.
You should now be able to switch to datasheet view and see the results
When the query is working to your satisfaction, save it with any appropriate name
Open a new query in design view
When you get the list of tables to include, switch to the list of queries and include the query you just saved
Change the query type to crosstab and update the query as needed to select rows, columns and values - look up "access crosstab queries" if you need more help.
Another tip to see what is happening here:
You can take the subquery - the parts inside the () above - and make
just that statement into it's own query, excluding the opening and closing (). Then you can look at it's design view to see what it does
Save it with an appropriate name and put it into the query above in place of the statement in () - then you can look at the design view.
Sometimes it's easier to visualize and learn from 2 queries strung together this way than to work with sub queries.
i have some tables that each one have different columns like this :
each User ( have ID ) can post to my website and Add some events, so each update goes to related table! but my problem is how show this information only in one Gridview . its something like facebook Timeline that shows your updates sorted by date .
i tried to use SQL join but its not a good way because i have 10 to 12 tables, joining all these tables is time consuming.
i want have a gridview that be bind from different tables on sort the information by their date ( each table have a date column )
sorry for my bad English.
You will need to use a single datasource for your Gridview, which means you need to join your tables in a single query, or use multiple Gridviews (one per table). I can't see why joining your tables in a query would be more time consuming than any other way you propose, assuming there was a way to do it within the Gridview, you'd just be doing the time consuming task on sort rather than on render.
Perhaps post your query and gridview code for a more specific answer.
Im using Asp.net (VB.net), in my Database :
have One table called (Trade), the same rows of this table are used from 3 different users, These users can make different updates on this table, they should see the basic informations of the table (I mean by the Basic, before the table (trade) has been updated)
The problem is here when the first user wants to modify the table's rows, the second and third user cannot see the basic information any more, and if they decide to change or update some data, the first will lose his updated rows..
The data will be overwritten every time the users make updates on the table.
What I want, is to know if there is a way to do like a copy, or an image of the table for the 3 users, and every user can update normally, without creating the same Table with the same rows 3 times??!
Update
My table structure is: Trade(trName, Carrier, POl, POD, Vgp, Qgp) There is no primary key..
Thank you..
Solution to your problem could be two copies of the original table. Show the original table always to the user as the initial data. And in second table keep the updated data always. Now the trick comes here to maintain the log, for that you have to maintain the log table, this table will have all the fields of original table along with one additional column "UserId", this will have the ID of user who has changed the value. Now each time before updating the data, copy it in the log table. If this suits your need then post the fields of your table then we can workout on the table structures.
Running the Databus server from the command line I have successfully uploaded timeseries data via curl, and am able to query the same data with the api. I'm unable to view any of the data in the table in the UI. After selecting "My Databus" -> Tables is says "You do not belong to any groups that have tables yet. Add some groups, then tables!!!". Navigating to the Database and selecting the table -> chart no data comes back there either.
I have noticed that the query it issues is from a recent time range, while the data I loaded is for an earlier time period. Is there a default way to show the most recent data available in a table?
Is your table type relational or stream? If relational, what is the primary key?
If time series, this url will give you the last 10 values because of the parameter 10 and reverse=true.
http://[yourhost]/api/firstvaluesV1/10/rawdataV1/[yourtablename]?reverse=true
If relational table, you can retreive all values like so
http://[yourhost]/api/getdataV1/select+c+from+[yourtablename]+as+c
replace either urls [yourhost] and [yourtablename] values.
We do not use the tables page much. It is better to click in the specific database as in My Databus -> Databases and then click on the database that has your table. We are about to add a view data link in there showing most recent 1000 values or something like that. There is already a view chart which shows most recent 2 hours(again, we want to change that to most recent 1000 data points instead as well).
