问题 I'm trying to create a service based on an Azure SQL Database backend. The service will be multi-tenant, and would contain highly sensitive information from multiple "clients" (potentially hundreds of thousands), that must be strictly isolated from one another and secured heavily against data leaks. "by design" Using so many individual databases would not be feasible, as there will be a lot of clients with very little information per client. I have looked into the transparent encryption

问题 Our dev, test and production environments all have similar setups using windows authentication and separate VMs for IIS 10 server and SQL Server 2016. Both VMs running Windows server 2016.

问题 I have a table that contains information regarding what they've done throughout the day. I need to get the start time/end time for each task.

问题 I am using SQL Server's Always Encrypted feature to encrypt a few columns in the database using a master key that is protected by a self-signed certificate. The certificate is created using SQL 2016's Management Studio and always defaults to an expiration date that is one year ahead of the issue date - it is stored in the Windows Certificate Store for the current user. Is it possible to extend the validity of this certificate to a value greater than a year? More specifically, can a

问题 I'm trying to setup a new Always Encrypted database using Azure Key Vault (I have previously had this working). In the SSMS Always Encrypted Wizard I can select the table and column to encrypt but I have a problem after selecting "Azure Key Vault" as the key store provider. I login and the window briefly pops up the dropdown that correctly lists my Key Vault in Azure but then it immediately goes away and has a warning triangle with the word "Purge" next to it and a "Try Again" button.

问题 I'm trying to use the Always Encrypted feature of SQL Server 2016 with .NET Core and seems like it can not be used (yet).
