// Thanks Bob Ward (http://aka.ms/bobwardms)
// and the folks at Stack Overflow (https://github.com/opserver/Opserver/blob/9c89c7e9936b58ad237b30e6f4cc6cd59c406889/Opserver.Core/Data/SQL/SQLInstance.Memory.cs)
// for putting most of the memory clerk definitions online!
/*
The SQL scripts use a series of IF and CASE statemens to choose the correct query based on edition and version of SQL Server, below the meaning of the numbers:
EngineEdition:
1 = Personal or Desktop Engine (Not available in SQL Server 2005 (9.x) and later versions.)
2 = Standard (This is returned for Standard, Web, and Business Intelligence.)
3 = Enterprise (This is returned for Evaluation, Developer, and Enterprise editions.)
4 = Express (This is returned for Express, Express with Tools, and Express with Advanced Services)
5 = SQL Database
6 = Microsoft Azure Synapse Analytics (formerly SQL Data Warehouse)
8 = Managed Instance
ProductVersion:
see https://sqlserverbuilds.blogspot.com/ for all the details about the version number of SQL Server
