识别SQL Server表上的数据压缩

Question

I am staring at many rows like this:

How can I find out how the column data has been compressed please?

Answer 1

Check if your table is compressed by reading this article . It also specifies how to decompress your data.

However, from your output it looks as if data is encrypted. Maybe it is done in the application layer, as SQL seems to output VARBINARY from encryption at displays as hex string when displayed in SSMS.
