What does all this actually solve? Presumably SQL injection might still decrypt contents and order by/where clause enumeration would still be possible regardless. Keys must be stored in memory, on-disk or via a secret server meaning column encryption would not mitigate the impact of RCE/full shell compromise. Add in the cost of column level encryption when querying large volumes of data, this seems to be entirely angled at gold plated compliance security theatre rather than solving any actual problem.
