Discussion board where members can learn more about Qlik Sense Data Connectivity.
Hi Everyone,
Is there an option to Dynamically change data source in Qlik sense?
For example, I have three streams(DEV, UAT, PROD ) and I need to connect to three different data sources(DEV, UAT, PROD),
Is there a way like I should not change the connection string but it should pick up the data source dynamically when I deploy in respective streams(DEV, UAT, PROD)? Can you please reply. Thanks in advance!
Thank you,
Ahamed
Hi Ahamed, did you figure out a way to do this? I am am looking to do the same thing.
Hi Ahamed,
I personally haven't tried anything regarding this, but the first thing comes to mind is an IF ELSE statement using a source-path that would be included in the script. Then when you "deploy" to a stream the files would change locations/paths. Therefore the script would automatically account for it.
A few functions that come to mind to get a path...
-GetFolderPath
-DirList
-FileList
-DocumentName
-DocumentPath
-DocumentTitle
Please let me know if you end up finding a viable solution. If I end up finding time to test this I will reply back.

Hi Derek,
If the Source is file system, then we can apply IF ELSE and use the functions which you mentioned.
-GetFolderPath
-DirList
-FileList
-DocumentName
-DocumentPath
-DocumentTitle
what if we are using OLEDB conection to connect to SQL server?
the ideal solution for this would be, We need some qlik function to identify the stream Name, that way we can apply IF ELSE and swap the connections.
thanks.
Hi,
First of all you need to create 4 data connection. DEV, UAT, PROD and POSTGRE_QSR(qlik sense database). We need QSR connection to fetch the stream name of the app.
let appId = DocumentName();
LIB CONNECT TO 'POSTGRE_QSR';
Temp_App_Stream:
load
ID as AppID,
Name as StreamName;
SELECT app."ID",str."Name"
FROM public."Apps" app
left join public."Streams" str on app."Stream_ID"=str."ID"
where app."ID"='$(appId)';
let DataSourceName = peek('StreamName');
DROP TABLE Temp_App_Stream;
LIB CONNECT TO '$(DataSourceName)';
If you get the logic, you are able to modify this script based on your needs.
Hope it helps.
