  I am testing on the AdventureWorks database (the OLTP version, not the data warehouse version).  This version has the 'dbo' schema and other schemas to.  I am trying to run a simply query and I get an error stating invalid object name 'HumanResources.Employee.BusinessEntityID'.  Here is the code:

  SELECT *
  FROM [HumanResources].[Employee].BusinessEntityID;

  This doesn't work either:

  SELECT *
  FROM [Employee].BusinessEntityID;

  When I run this code, I get a result set:

  SELECT *
  FROM [HumanResources].[Employee];
  

  1. Why does the first query not work?
  2. How can I query the BusinessEntityID column if these queries don't work?

  I am in the AdventureWorks2017 database.

  Nevermind.  I see what I did wrong.  Only the schema and table should be in the FROM clause.  The column names should be in the SELECT statement.
