Unit Testing Dynamic SQL

Jay Robinson lays out a pattern:

Dynamic SQL (aka Ad Hoc SQL) is SQL code that is generated at runtime. It’s quite common. Nearly every system I’ve supported in the past 30 years uses it to some degree, some more than others.

It can also be a particularly nasty pain point in a lot of systems. It can be a security vulnerability. It can be difficult to troubleshoot. It can be difficult to document. And it can produce some wickedly bad results.
