Now that we have our columns encrypted, lets look at what happens when we try to run the following SELECT statement within an SSMS query tab: As it turns out, the LoginID and NatID columns are returned as encrypted values, as shown in the following table. In a multi-tenant application all the data for a tenant might be stored together in a shard using the tenant ID as the shard key. SQL In addition, you should not perform write operations against the table during the encryption process because of the potential for data loss. The view also returns the algorithm used to encrypt the column encryption key (which is always RSA_OAEP) and the actual encrypted value of that key, as shown in the following table. In a multi-tenant application all the data for a tenant might be stored together in a shard using the tenant ID as the shard key. Optimise price-performance and manage multi-tenant application complexity by sharing resources through elastic pools. For this, we can use one that has already been created, or we can have the wizard do the work.
