Simple SQL join question.  (I think I need a self join here with a distinct or maybe group by.)

Last Modified: 2012-05-11
Take this table – Columns ‘Key’, ‘Name’, ‘Street’ and ‘ZIP
123      Smith      Main St            80424      
123      Smith      Main St            80424
234      Jones      Main St            80424      
345      Clark      Main St            80424

Input information for where clause is street name only.  I want to return three records (123, 234,345).  So, just one occurrence of 123 (either one).
Select distinct Key, Name, Street, ZIP from table where street = ‘Main St’
Returns nothing
