Well, I think the script promise compatibility for mysql only, so I reflected it in this message. I not planned it as a common script for many RDBMS though it could be applied with minor changes to other SQL-based systems.

TDH can be totally ignored. It is dome term sued in my project, forgot to remove.

Don't understand the syntax here. What is this stg prefix?

stg is just the schema or the user name in which the table is being created. This was done as we have two layers of tables with same name, same like stg and pub schema in data warehouse systems.

I thought "go" doesn't work with mySQL as a delimiter by default. Is it really works with mysql without redefining it with delimiter command?

Well frankly I changed this script to suite Azure SQL database. So may be if you find suitable you may create a separate branch for this. :)
And Of course #Vips needs to be ignored. This was basically a TAG kind of thing which I added to mark the changes done by me.
