I was playing around with configuring Polybase this morning. Nothing to exotic, just installing the feature getting started. I got everything installed and was about ready to created my data source. The command to that is as follows:
CREATE EXTERNAL DATA SOURCE AzureStorage
TYPE = Hadoop,
LOCATION = ‘wasb://email@example.com’,
CREDENTIAL = AzureStorageCredential);
Unfortunately, it returned the following error:
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near ‘EXTERNAL’.
So what was the fix? A reboot after installing Polybase. The official documentation refers to restarting SQL Server, which I did. Nothing warned me to reboot, but rebooting fixed the error.
