We have a migration task, which require to migrate ~30GB data from SQL server to SAS grid. We already have close to 50 reports using SSIS/SSRS and those need to move entirely to SAS grid. I am more familiar with SAS and haven't worked on SSIS/SSRS stuff.
How do I go about moving the process to SAS?
I know I can use Passthrough in SAS to call the SSIS/SSRS stuff from Proc SQL, but since they want everything needs to be coded in SAS, I am wondering if there is an easy way.
Is there a tool that can convert the SQL code and writes Proc sql code in SAS?
Thanks!

You should be able to view the queries behind the SSIS jobs (run the report, then view the details behind it). Once you have the queries, copy/paste the SQL code into a SAS SQL passthrough statement. The table returned should give the same results as the report. It's then up to you to format the output as desired.

As question states:
Within powerBi there from the 'Get Data from SQL Server' -> connecting to the SQL Server
there are two options import and advanced. With Advanced, you can write a sql query to get the data or the default is import. This shows all the tables on the server and you can just ETL from a click.
What is the real difference?
If you are comfortable writing your own T-SQL select statement, you can use it to bypass the Power Query editor and send your desired statement straight to the SQL database. That is also handy if you have code already written out from a previous query or project, which you can just paste into the Advanced query window.
If you use the Power Query Editor to build you query step by step, you have a better visualisation about what data is returned by the previous step(s), and you can apply data manipulations after sighting the data.
Power Query uses query folding, which means that your individual steps are analysed and then translated into the most efficient SQL code before it is sent to the server.
That means that even if you don't speak T-SQL very well, you can still build efficient queries with the Query Editor, and if you feel you are an accomplished T-SQL developer, you can shortcut the Query Editor steps altogether. Of course that means that it is also possible to use "Advanced" and write clunky, inefficient T-SQL that performs slower than going through the Query Editor steps would.
In the end, it comes down to preference and familiarity. A seasoned DBA might just quickly write out a Select statement, a SQL rookie might prefer to click a few ribbon commands instead. The result can be identical in returned data and performance.
I am looking to see if the capability is there to have a custom SSMS sql query imported in SPSS (Statistical Package for the Social Sciences). I would want to build syntax that generates this query as my new dataset that I can then continue my scripted analysis. I see the basic query capability of one table from a Sql Server but I would like to create a query that joins to many tables. I anticipate the query to be a bit complex with many joins and perhaps data transformations.
Has anybody had experience or a solution to this situation?
I know I could take the query and make a table of it that SPSS can then connect to but my data changes daily and I would need a job in another application to refresh this table before my SPSS syntax would pull it and I would like to eliminate that first step by just having the query that grabs the data at the beginning of my syntax.
Ultimately I am looking to build out my SPSS syntax and schedule it in the Production Facility to run daily.
I have T-SQL queries stored on a hard drive: I:\queries\query1.sql and I:\queries\query2.sql.
I usually work in a way that I execute a query from a drive, and then I copy results into Excel, and then I work on it.
My problem here is that query1.sql is already long, and now I would like to extend it by getting a result of query2.sql, and join it with a result of query1.sql.
What I could do is appending a code from query2.sql to query1.sql. But then the query is getting really long and hard to maintain.
I would like to do something like this:
SELECT * FROM ("Result of I:\queries\query1.sql") q1
LEFT JOIN ("Result of I:\queries\query2.sql") q2 ON q1.ID=q2.ID
Is there any way to write a query or stored procedure, which will be again stored on a drive to do this?
Basically, you need to ask your DBA for a database when you are able to store things in the database. This can be on the same system where the data is stored. Or, it could be on a linked system. Gosh, you could run SQL Server locally and store the information and data there.
Then, the queries that you are storing in files should be views in the database. You can then run the queries and store and combine the results locally.
You are essentially recreating database functionality using text files and data files -- going through a lot of effort when SQL Server already supports this functionality.
To expand on Gordon's comment (+1), why are you running scripts off of a drive? Most DBA's I've known would treaten bodily harm over this as executing code that they can't control / troubleshoot / see source code control on brings a whole host of security and supportability issues.
Far better to store this code in a Stored Procedure, which will have a saved query execution plan, can be tracked using various DMV's, and have permissions assigned to it, then your outside Excel doc can just set a connection and execute the SP.
RIght at the outset I'd like to say that I am NOT a Cognos Guy .So I have totally disconnected myself from developing cognos cubes / reports whatever you want to call it.
There are COGNOS queries auto generated - very badly written that will cause the Teradata ( DBS 15.1.x ) system to Hog on spool & CPU . I can tune them beautifully after I pull them out from DBQL. I want to know HOW can I implement Custom Queries that can be run periodically as batch reports instead of Cognos auto-generating these queries.
E.g. You create a cube - its writes code behind it and then you can open the code and write custom code that is equivalent to the original code but performs a lot better. Then when you open the cube again - it remembers there is a custom SQL and runs that instead of its own auto generated SQL . This is just how I imagine one way it can do it but again- I am not a cognos resource so pl dont flag me down for lack of knowledge. That is exactly what I am trying to get an idea about
Thanks for bearing with me
In Framework Manager you can create one Query Subject with complex query inside. Do not import tables etc. Just create QS in put your query inside.
You need to use stored procedure to return your expected data and add it to Model.
Then instead of using couple of tables in Cognos report studio (and joins), add one query and point it to your stored procedure. This way your Cognos report will execute the procedure instead of generating query (which may not be efficient in many cases)
I have an SQL Query I'm using to Pull Beds by Unit and the related Number of Beds in Use and Available.
What is the SQL Syntax to have the results of the query save to an excel file (existing or new).
Please Note: I have been searching and I can't believe this isn't easy to figure out. Lots of people seems to use other tools but I want to do it in SQL Stored Procedure - Is this possible?
Thanks so much for your help!
The easier way to do this is from Excel, utilize a connection to your SQLDB and then pull the data into excel, that is the most efficient way to do it.
