How do you delete/empty/clear an SQL Analysis Services Cube? - ssas

Ok, this is a noobie question, can't seem to find the answer in google.
As we know, the SSAS cube is stored in "C:\Program Files (x86)\Microsoft SQL Server\MSAS10_50.MSSQLSERVER\OLAP\Data"
How do you empty an SQL Server Analysis Services Cube? I do not want to delete the entire cube, I just want to delete data in it.
Thanks

In order to delete all data of a cube, you unprocess it. The easiest way to do that is as follows:
Either in Management Studio right-click the Analysis Services database, or in BIDS, right-click the project.
Then select "Process",
in the dialog that appears, change the selection from "Process Full" to "Unprocess",
and finally, click OK.

analysis services datasource migrated

I have none experience with SSAS, I had this cube working perfectly…
The underlying tables that it was using were from a database, let’s call it ‘ABCD’. The problem is, that for other reasons ABCD database had to be split in ‘AB and ‘CD. Half the tables have been migrated to AB and the other half to CD. In my mind I want to open something as ALTER, edit the DB name, and everything would work as before, but SSAS is a bit of a black box for me; can I achieve this?
I know I can just access ABCD and create views to AB and CD and mask my problem, but I would really love to know how to modify the scripts that build the cube….
My recommendation is to just add views into the AB database which point to the tables which have moved to the CD database. Then you can edit the data source from Management Studio and point it to the AB database. (You just connect Object Explorer to Analysis Services, expand down to the database, expand to the Data Source, then double click to edit.)
If that's not an option then you can change the cube source code as follows...
I'm assuming it's a Multidimensional cube, not Tabular. If you already have Visual Studio and SSDT installed, great. Otherwise, install the latest SSDT which runs in Visual Studio 2015 as it's backwards compatible.
In SQL Server Management Studio, connect Object Explorer to Analysis Services and then right click on the database and choose Backup.
In Visual Studio, File... Open... Analysis Services Database. You are editing the cube "source code" live now. As soon as you save a change it will deploy it to the server.
Double click the data source and fix the connection string. Make sure it's using a version of the driver that's on the SSAS server. Point it to the AB database.
Then double click the DSV. In the tables list on the left, right click on each table which was moved to the CD database and choose Replace Table... With New Named Query. Click the "Switch to Generic Query Builder" button and then edit the query to look something like:
select *
from CD.dbo.YourTable
Click Save.
Then go back to Management Studio, right click the database and choose Process. Do a Full Process on the database. It should succeed and be up to date.
It is possible to reverse engineer a deployed SSAS database. The above assumes that's not important to you. But if you need to do this, in Visual Studio do File... New Project... Templates... Business Intelligence... Analysis Services... Import From Server (Multidimensional and Data Mining).

Can't create database in SQL SSAS

I installed Microsoft SQL Analysis Service because I need it to run a forecast analysis from Excel using the Data Mining Plug-in.
When I open MS Management Studio and connect to the SSAS I don't know how to create a new database.
When I right-click over Databases there is nothing like Create Database or New Database.
This is the image of my problem:
Well... I solved my problem reinstalling the suite selecting all of its options.
I still don't know what may cause this problem if not chosen in the instalation options but now I have the New Database option and could finish my job.
Thanks.
I managed to solve this problem by switching Analysis Services from Tabular to Multidimensional mode:
Stop SQL Server Analysis Services service
Go to the config folder, e.g. C:\Program Files\Microsoft SQL Server\MSAS15.SQL2019\OLAP\Config
Copy file msmdsrv.ini to another folder (you can't edit it here directly)
Open the copied file and search for the DeploymentMode xml tag
Set the value to zero
Save the file, copy it back to the Config folder
Start the service
You can use SQL Server Management Studio to create a new, empty database on an instance of SQL Server Analysis Services.
To create an Analysis Services database
Connect to an Analysis Services instance.
In Object Explorer, expand the node for the connected Analysis Services instance.
Right-click the Databases node of the Analysis Services instance and select New Database.
In the New Database dialog box, in Database name, type the name of the new database.
In Impersonation, provide impersonation information for the new database.
In Description, type the optional description for the new database.
Click OK.

SSAS Cube processing

I have deployed my SSAS solution to production. On the production server, I want to process my cube, but when I right click on the ssas cube and choose "Process", I recieve the follwong error:
The 'Database' with 'ID' = 'XXX' doesn't exist in the collection.
Has anyone encountered this error in Microsoft SSAS? If so, can anyone tell me what to do to resove this error ?
Check to see what the Id of the database is by right clicking on the database and selecting properties. Check the equivalent in visual studio and confirm it matches. If you have renamed the analysis services project (maybe for a backup), the id of the database does not get renamed and sometimes gets messed up in the XML file.
Try re-processing the dimensions on their own and then the cube. Failing that, if this is the first process (i.e. the cube is not live), try deleting and redeploying from visual studio.
You can re-deploy the OLAP database from SSDT with a different name and before you do you just need to change the database name and set the Processing Option to Full. You can set these options under Project's Configuration Properties->Deployment.
I had the exact same problem. I solved it by editing the roles in my SSAS database :
And then, check the boxes depending on what you want your job to do :
Then, you can process your cubes with your SSIS Jobs.
it can either be roles or kerberos, I got a similar error when the kerberos authentication wasnt setup in the cube server to interact with database server.

How to get script of SQL Server data? [duplicate]

This question already has answers here:
What is the best way to auto-generate INSERT statements for a SQL Server table?
(24 answers)
Closed 6 years ago.
I'm looking for a way to do something analogous to the MySQL dump from SQL Server. I need to be able to pick the tables and export the schema and the data (or I can export the schema via SQL Server Management Studio and export the data separately somehow).
I need this data to be able to turn around and go back into SQL Server so it needs to maintain GUIDs/uniqueidentifiers and other column types.
Does anyone know of a good tool for this?
From the SQL Server Management Studio you can right click on your database and select:
Tasks -> Generate Scripts
Then simply proceed through the wizard. Make sure to set 'Script Data' to TRUE when prompted to choose the script options.
SQL Server 2008 R2
Further reading:
Robert Burke: SQL Server 2005 - Scripting your Database
SQL Server Management Studio
This is your best tool for performing this task. You can generate a script that will build whichever tables you wish from a database as well as insert the data in those tables (as far as I know you have to export all of the data in the selected tables however).
To do this follow these steps:
Right-click on your database and select Tasks > Generate Scripts
In the Generate and Publish Scripts wizard, select the "Select specific database objects" option
Expand the "Tables" tree and select all of the tables you wish to export the scheme and data for, then click Next
In the next screen choose how you wish to save the script (the Output Type must remain set as "Save scripts to a specific location"), then click the Advanced button in the top right corner
In the newly opened window, under the General section is a setting called "Types of data to script", set this to "Scheme and data" and click OK
Click Next, review the export summary and click Next again. This will generate the script to your selected destination.
To restore your database, simply create a new database and change the first line of your generated script to USE [Your.New.Database.Name], then execute. Your new database will now have all of the tables and data you selected from the original database.
I had a hell of a time finding this option in SQL Management Studio 2012, but I finally found it. The option is hiding in the Advanced button in the screen below.
I always assumed this contained just assumed advanced options for File generation, since that's what it's next to, but it turns out someone at MS is just really bad at UI design in this case. HTH somebody who comes to this thread like I did.
If you want to script all table rows then
Go with Generate Scripts as described by Daniel Vassallo. You can’t go wrong here
Else
Use third party tools such as ApexSQL Script or SSMS Toolpack for more advanced scripting that includes some preprocessing, selective scripting and more.
Check out SSMS Tool Pack. It works in Management Studio 2005 and 2008. There is an option to generate insert statements which I've found helpful moving small amounts of data from one system to another.
With this option you will have to script out the DDL separately.
SqlPubWiz.exe (for me, it's in C:\Program Files (x86)\Microsoft SQL Server\90\Tools\Publishing\1.2>)
Run it with no arguments for a wizard. Give it arguments to run on commandline.
SqlPubWiz.exe script -C "<ConnectionString>" <OutputFile>
BCP can dump your data to a file and in SQL Server Management Studio, right click on the table, and select "script table as" then "create to", then "file..." and it will produce a complete table script.

I know this has been answered already, but I am here to offer a word of warning.
We recently received a database from a client that has a cyclical foreign key reference. The SQL Server script generator refuses to generate the data for databases with cyclical references.

Editing SQL query with Visual Studio 2008

Would you recommend me the best approach to edit SQL query with Visual Studio 2008 Professional, please?
I know I can open Query window from context menu in Server Explorer and edit text in SQL Pane. But unfortunately I am not allowed to save query to a file and Find and Replace commands are not working there.
Alternatively I can open text file with extension .SQL in Visual Studio editor obtaining syntax highlighting and full editing capabilities but losing possibility to execute the script.
Now I copy query text from one window to another and back but I hope there is better solution.
Many thanks for suggestions!
When I have to connect to Sql Server, I use NetBeans, as it has a number of features that make it much easier to use than Visual Studio. One of these is intellisense, which is very useful when you have an alias for a table name and lots of long field names. The general handling of connections and connection pools is also much cleaner in NetBeans. I could go on, but suggest trying it for yourself. You will almost certainly need the Sql Server jdbc driver, which can be downloaded from http://msdn.microsoft.com/en-us/data/aa937724.aspx
If you create a Database project within your solution in Visual Studio, then you can set up a default database connection for that project. Then any *.sql files that are included in the database project can be executed against that connection. What I usually do is select the text to be exectued and right-click it, then select "Run Selection".
You can set up any number of database connections under the "Database References" node in the solution explorer, and choose the one you want to run your query against.
Wow you are right, this is a real pain. Would it be acceptable for you to use a local copy of the SQL Management Studio (the name might be wrong)? You would be outside of VS but you could still edit your query and run it at the same time. Definitely not optimal but better than nothing.
Good luck.
