When troubleshooting issues regarding connection to Data Source, it is crucial to determine whether a Connection String is correctly created.
Although QlikView has a built in wizard to generate connection string, this article tries to generate connection string externally.
Follow these steps:
Create a new TXT file, name it as "string.txt".
Rename it to "string.udl". Note "Hide extensions for known file types" option needs to be turned off in Windows.
Double-click "string.udl", "Data Link Properties" window shows up.
Choose appropriate provider in "Provider" tab, modify the settings in "Connection" tab so that Test Connection succeeds.
Hit OK to save the file. Then open it in Text Editor, the Connection String should be there.
By default the generated Connection String does not include Password. In order to establish successfully connection, a clear text "Password=XXXXXX" needs to be inserted into the string. This is for test purposes only and should not be used in production.
