I am trying to perform a select on the below code, but I am not performing the select correctly.  Could you let me know what the query should look like?

Company --> Company.Code
Company_Rules --> Company_Rules.Company

Sample Input Data


Company Rules
Company                      Rule Code
1                                        100              
1                                        200
3                                        101

Desired Output
Code                      company
1                                1
2                              Null
3                                3

In essence I want all of the company data that that with the matching company_rules data.  But the resulting output does not return multiple rows of company_rules.  The data that does not find a matching company_rules field is also return.
