In my SSAS tabular model I have a calendar dimension, and a wave dimension for half-year data only. The data flows to these tables as such:
Fact Table ---> Wave Dim <---> Calendar
No matter what I do I cannot hide the wave table from Excel users. The table shows hidden in Visual Studio, but in Excel it shows the table with no fields in it. I have tried deleting the table and reloading it with no avail. My assumption is that it has to do with the way it's connected to the Calendar dimension, but I can't seem to find anything on my issue. Any help would be much appreciated.
This is a tough one to answer without viewing your model.bim file. Based on your information I have two guesses on what could be the issue, although this may very well not be it:
1) It sounds like you've marked all fields in the Wave table as hidden, but not the Wave table itself. Could this be the reason?
2) Perhaps you are using perspectives, and only hid the Wave table in a perspective rather than in the Model (default perspective)?
The relationships in your model should have no impact on whether a table is displayed in client tools or not.
Feel free to upload your model.bim file if the above does not help.

Currently I'm working with a dashboard in which I'm pulling data (this data comes from 2 tables or dimensions) from a star schema, I'm displaying the data in a table component, and this data is not being displayed correctly because it looks like there is redundancy due to the column status(This column originally calls name and it is in the pracHeaderStatus table). Here I'm adding some screenshots:
Relationships:
Result:
(The ID's repeat many times)
Note:
I do not get this problem with querying my data from sql server
Greetings!
Look at the arrows in the diagram. Notice that the Project Title is unable to filter the status Name. In order for the relationship to work as you expect, there has to be a path between the tables that doesn't go "uphill" (opposite direction of the arrows).
You should be able to fix this by changing the relationship between pracDetails and pracHeaderStatusto filter both directions. Double click on the relationship line to edit.
I talked with the people that made this database and apparently this data was being retrieved from a transactional database while power BI was interpreting it as a star schema, so in other words. The problem is that the relationships are wrong because apparently Power BI always tries to denormalize the data, thinking that is a star or snowflake schema.
Good morning everybody, this is the first time I write in this forum so, i'm sorry if I do some error!!!
I'm working on a project in Visual Studio where I'm connecting to an Access Database. The most important thing is that this Database is not mine and I can't modify it because it is updated daily by another automatic software.
I have to think that this database is "Read Only".
This database only has tables with primary key but there are no relation between tables.....it really looks like different Excel sheets!!!
I don't have problem to import the tables in a DatagridView of my Visual Studio project but in these tables the data are not easy to be understood for example:
there is a column named "Color" where the color are filled like number but there is not another Table who contain the color code. I know in my mind that color 1=Red, 2=Orange, 3=Brown etc.....
What I want to do?
I want that in my DataGridView won't be show the numbers but the color name so I need to modify my DataGrid source before display data.
How is did my project?
I have my DatagridView whose data source is a BindingSource that has a Dataset as DataSource. On my Load event I use the "Fill" method of my TableAdapter to display my tables data
Could someone suggest me how modify data before display them?
Thanks a lot
Giacomo
If all you are dealing with is a limited number of values in one or two fields, you could select the records using a query and obtain the color as follows:
SELECT Table1.ID, Table1.FldA, Table1.ClrFlag, IIf([clrflag]=1,"RED",IIf([clrflag]=2,"Orange",IIf([clrflag]=3,"Brown","Unknown")))
AS MyClr
FROM Table1
If there are many lookup's to do, I would create my own database with tables of code translations and join the two databases to produce my result. The following is an example of SQL pulling from two databases:
https://support.microsoft.com/en-us/help/113701/how-to-access-multiple-databases-in-an-sql-query-in-vb-3-0
please bear with me; I'm not particularly confident with MS Access, although I am quite experienced with SQL Databases from website work.
For my sins, I have been tasked with developing a database which will unify the hundreds of spreadsheets which we currently use to record details of our clients, work, and other stuff... The database is established and built, but I am now working with the forms to allow data entry.
I have a datasheet form (we have a member of admin staff who is hell-bent on refusing to use forms, so a datasheet form seems to be the best way to appease her!) and it is bound to a specific table ('referrals') to allow a user to input data into that table. It looks like this:
However, I need to be able to load values from another table ('pupil_details') into the 'UPN' field so that if a pupil already exists in the 'pupil_details' table, the user can pick that pupil and have their details automatically filled into the form for convenience.
The form's Record Source is currently:
SELECT referrals.*
FROM referrals;
The most obvious way to do this seemed at first to be to use a join query for the form's record source, along the lines of:
SELECT referrals.*, pupil_details.UPN
FROM referrals LEFT JOIN pupil_details ON referrals.UPN = pupil_details.pupil_id
and then use this as the control source but when I do this, it breaks the functionality of the form (displays all the records, prevents it being used to enter data)
So, can anybody suggest to me how I might be able to get the 'UPN' field to display a list of records based on this query when a user types into it:
SELECT pupil_details.UPN, pupil_details.name, pupil_details.date_of_birth FROM pupil_details
But then enter the details into the 'referrals' table when the user submits the form? Sort of like this that I mocked up in Photoshop:
I'm stumped, and half a day on Google has left me none the wiser... :(
Thanks!
You should use a continuous form, not a datasheet, it will give you a lot more control, but still look like Excel. Once you have the form, you can add a combobox to get the details you want. It is nearly always best to avoid Excel attitudes in Access.
I have done an MS SQL Query in excel.
I have added extra colums in the excel sheet which I want to enter manual
data in.
When I refresh the data, these manually inputted columns become misaligned
to the imported data they refer to.
Is there any around this happening.
I have tried to link the imported data sheet to a manual data sheet via
vlookup but this isn't working as there are no unique fields to link together.
Please help!
Thanks
Excel version is 2010.
MS SQL version is 2005.
There is no unique data.
Because excel firstly looks like this.
when we entered a new order in to database Excel looks like this
Try this: in the External Data Range Properties, select "Insert entire rows for new data".
Not sure, but worth a try. And keep us updated of the result !
edit: And make sure you provide a consistent sort order.
There is no relationship to the spreadsheets external data and the columns you are entering. When refreshing typically the data is cleared and updated though there are other options in the external data refresh menu you could play with. You could play around with the External data options in the menu to see if changing the settings on what happens with the new data would help.
If you want your manually entered data to link to the data in the embedded dataset, you have to establish the lookup with a vlookup or some formula to find the rows info and show it.
Basically you are thinking the SQL data on the spreadsheet is static, but it isn't unless you never refresh it or disconnect it from the database
note that Marcel Beug has given a full solution to this problem in a more recent post in this forum # Inserting text manually in a custom column and should be visible on refresh of the report
he has even taken the time to record an example in a video # https://www.youtube.com/watch?v=duNYHfvP_8U&feature=youtu.be
I would like to cross-reference construct a distance chart similar to the one here (example is a road-distance cross-reference chart) and, ideally, store the data in SQL Server 2008 (preferably the Express version). It needs these properties / abilities
Every column has a corresponding row with the same name (ie. not misspelled like my example).
Changing the value at one Row-Column intersection would update the mirror intersection (Column-Row) or the mirror data could be ignored.
The distance-values would need to be end-user editable.
The end-user would need to be able to add, delete or rename a column/row pair.
The end-user needs to be able to sort the columns and have the rows move automatically.
There could be hundreds of pairs.
a look-up query needs to find a distance given a start & destination (Row & Column)
The distance chart is reasonably straightforward to implement in Excel. Considering this, am I better off...
Using Excel as the user editing UI and then updating an SQL 'thing' with the new data?
Using Excel as the data-source even if it means performance issues with querying the data?
Using an as-yet undiscovered stroke of genius detailed here in an answer?
Sure looks like an Excel application to me, start to end. (heh)
I can't imagine your users typing enough data in to make performance an issue. Excel will only take 32757 rows by ditto columns. If that's enough, I'd say you're golden.
