Query - Need Different Results

Select
 LTRIM(RTRIM(UPPER(ISNULL(dbo.Street.Prefix_Full, '')))
+  ' ' +     RTRIM(UPPER(ISNULL(dbo.Street.Street_Name, '')))
+ ' ' +      RTRIM(UPPER((COALESCE(CASE WHEN dbo.Street.Suffix_Cnty IS NOT NULL THEN Suffix_Full
                                 ELSE dbo.Street.Suffix_Bell
                          END, ''))))) AS Name
      FROM dbo.Segment INNER JOIN dbo.Street ON dbo.Segment.Street_ID = dbo.Street.Street_ID
  Order By Name

When Running this Query i get close to the right results but i need to tweak something. I'm stuck at this part.

Description
Suffix_Bell is the abbrviation of Suffix_Full.  
Suffix_Cnty is also the abbrviation of Suffix_Full.
When Suffix_Bell is populated ( example: Rd(in Suffix_Bell) = Road(in Suffix_Full) Suffix_Cnty will be Null. and Vise Versa.

Suffix_Bell & Suffix_Cnty connot both be populated, its one or the other or niether.

The wierd part of this request is.

When Suffix_Cnty is not null i need to populate the Name field with
Prefix_Full + Street_Name + Suffix_Full (When Suffix_Cnty IS NOT NULL)

When Suffix_Bell is not null i need to populate the Name field with only
Prefix_Full + Street_Name. The Suffix_Bell Column gets put in the Type Field.
Which reading back i think i explained this part wrong to start. Sorry about that

do you mean this?

Select
 Upper(LTRIM(RTRIM(ISNULL(st.Prefix_Full, '')) 
+  ' ' +     RTRIM(ISNULL(st.Street_Name, '')) 
+ ' ' +    ltrim(rtrim(case when st.suffix_cnty is not null then suffix_full else '' end))) as Name
, case when st.suffix_cnty is not null then '' else suffix_bell end as type

      FROM dbo.Segment as seg
     INNER JOIN dbo.Street  as st
           ON seg.Street_ID = st.Street_ID
  Order By Name 

Open in new window


if not please explain , with some example data....
and confirm suffix_full already contains the expansion of rd->road that doesn't require another lookup..

The results are showing me the attached document.
Line 229 - Allens Alley (This is proper) as Suffix_Cnty is not null
Line 223 -Alexander Street (Wrong) As Suffix _Cnty is null.
I having trouble understanding when its not pick the data properly.

I need Alexander Street to show only as Alexander which is the Prefix_Full + Street_Name Part. I DO NOT WANT THE STREET

Blank is not NULL

+ ' ' +    ltrim(rtrim(case when nullif(st.suffix_cnty,'') is not null then suffix_full when nullif(st.suffix_bell,'') is not null then '' else suffix_full end))) as Name

     INNER JOIN dbo.Street  as st
           ON seg.Street_ID = st.Street_ID
  Order By Name

but really you need to police your data better if spaces/blank is not valid then you should force it to null.... maybe you should consider triggers or constraints to enforce your data integrity... otherwise you need excessive use of functions like nullif ,, which will have an impact on query performance..
