  Hello,

  Can you please clarify the following:

  In Azure SQL DB both ALLOW_SNAPSHOT_ISOLATION/READ_COMMITTED_SNAPSHOT are set to ON:

  ALTER DATABASE MyDatabase  SET ALLOW_SNAPSHOT_ISOLATION ON 

  ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON

  Is it sufficient to implement RCSI or I still need to add either to connection string or right to the top of the query:

  SET TRANSACTION  ISOLATION LEVEL  SNAPSHOT

  Anything else?

  Thank you
