Add Test

[GrimTheReaper]

I'm thinking we try to test this against the major SQL DBs, such as Oracle, MySQL, Postgress (probably not needed since they have a pretty snazzy client), MsSQL/TSQL/SQLServer, and whatever else that I am probably forgetting.

I would like to employ docker to do this, as it would make spinning up test environments and actually testing our functionally reasonable.

Consider doing tests in 2 phases:

1. package level logic tests for individual functions (DB interactions can be handled over https://github.com/DATA-DOG/go-sqlmock
2. integration tests at the external level <pkg>_test using live databases in docker-compose.

This should allow you to keep a smooth developer experience with the unit tests while still having your full "real world" coverage at the integration level.
