Question

I’m working with the AdventureWorks example DB – we’re running SQL Server 2008R2, so I assume that’s the edition of AdventureWorks (I have read-only access). I’m trying to get a list of sales managers so that I can then determine a couple employee/manager relationships.
I’m getting two sets of three differently named people, with the same job title, with their CurrentFlag set to 1 (active) with slightly different queries. I do notice that one result group has the same contactID and employeeID, but I’m not sure what this may indicate.

So the question is: Why am I getting completely different results with these two queires? I would think I’d get six results for each – the queries are matching employee table Titles.

• SQL Query 1:

  select 
     c.FirstName, 
     c.LastName, 
     c.ContactID, 
     e.EmployeeID, 
     e.Title, 
     c.Title, 
     e.CurrentFlag
  from Person.Contact c 
  inner join HumanResources.Employee e
     on c.ContactID = e.ContactID
  where 
     e.Title like '%Sales Manager%'
  

• SQL Query 2:

  SELECT 
     e.EmployeeID, 
     (c.FirstName + ' ' + c.LastName) as 'First Name and Last Name', 
     e.Title
  FROM HumanResources.Employee e 
  INNER JOIN Person.Contact c
      ON e.EmployeeID = c.ContactID
  Where 
      e.Title LIKE '%Manager%'
      AND
      e.Title LIKE '%Sales%'
  ORDER BY e.EmployeeID;
  

UPDATE: These are my results:

• SQL Query 1:

  -------  -------  ----  ---  ----------------------------  ----  --
  Stephen  Jiang    1011  268  North American Sales Manager  NULL  1
  Amy      Alberts  1013  284  European Sales Manager        NULL  1
  Syed     Abbas    1012  288  Pacific Sales Manager         Mr.   1
  

• SQL Query 2:

  ---  ---  -----------  ----------------------------  ---  --
  268  268  Gary Drury   North American Sales Manager  Mr.  1
  284  284  John Emory   European Sales Manager        Mr.  1
  288  288  Julie Estes  Pacific Sales Manager         Ms.  1
  

Answer 1

The only diffrents i can see is this:

where 
   e.Title like '%Sales Manager%'

And this:

Where 
 e.Title LIKE '%Manager%'
    AND
  e.Title LIKE '%Sales%'

The first query says that bring me all titles that has '%Sales Manager%' you can have for ex this output:

Account Sales Manager
some Sales Manager
Sales Manager something else

The second question says bring me all the titles that has '%Manager%‘ and '%Sales%' so you can for ex have:

Sales Account Manager
some Sales some Manager some 
Sales Manager some else thing
Manager Sales

And this join can not be corrent

INNER JOIN Person.Contact c
    ON e.EmployeeID = c.ContactID

Don’t you mean:

INNER JOIN Person.Contact c
        ON e.ContactID= c.ContactID
