SSIS And Always Encrypted

Jakub Szymaszek links to two articles on using SSIS with an Always Encrypted database.

Using Always Encrypted:

The SQL Server 2016 Always-Encrypted feature is only supported by the ADO.NET  provider currently. It is not supported by the OleDB provider and therefore any OleDB-provider-related transformation tasks such as Fuzzy Lookup will not support Always Encrypted feature.

In the “Execute SQL Task”, parameter binding for some encrypted SQL types is not supported, because of data type conversion limitations in Always Encrypted. The
unsupported types are money, smallmoney, smalldatetime, UniqueIndentifier, DatatimeOffset, time and date.

Lookup Transformations

Add an ADO NET source connect to the table “Customers” (please ref to here get more detail about how to use ADO NET Source to connect encrypted table).

Then create a cache connection manager “Customer Cache” and set the column information as below:

Based on article #2, it looks like you can’t simply use a Lookup transformation on an Always Encrypted column; you need to pull the results into cache first and then query the cache.  That’s not exactly difficult, but if you have an encrypted column, make sure you’re not writing those columns out in plaintext because of the cache option you selected.

Monica Rathbun finds trouble with Always Encrypted: The real challenges started when the client began to test their application code. The first thing we hit was triggers. The table had several insert triggers associated with the columns that were now encrypted. Since the data was now encrypted the insert triggers would fail. Again, we lucked […]

Storing Credentials For Containers

Andrew Pruski shows how to store a credential using Powershell and pass it into a Docker container: I work with SQL Server in containers pretty much exclusively when testing code and one of my real bug bears is that SQL Server in containers does not support Windows authentication (unless you’re using Windocks). So when I’m working […]
