I am unable to DROP Azure SQL Database in SSMS
DROP DATABASE xxxx
and getting this exception
Msg 42019, Level 16, State 4, Line 2
DROP DATABASE operation failed. Internal service error.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
If you are connected to xxxx database you cannot perform drop database from within. You need to connect to master db and then perform DROP DATABASE xxxx.
Azure SQL Database
You must be connected to the master database to drop a database.
The DROP DATABASE statement must be the only statement in a SQL batch and you can drop only one database at a time.
Second you should check if there is DELETE LOCK that prevents from dropping database.
