It should be like

Select <What You Want To Match>
  Case WHEN "<What should be matched>" THEN ..
  Case WHEN "<What should be matched>" THEN ..
ELSE ...
END

If you want to use it in vb.net then here is a example


Select Case parameter
    Case "userID"
                ' does something here.
        Case "packageID"
                ' does something here.
        Case "mvrType"
                If otherFactor Then
                        ' does something here.
                Else
                        GoTo Case Else
                End If
        Case Else
                ' does some processing...
                Exit Select
End Select

In SQL, I don't need it in vb
Case when tmp1="ON" then
    Case when "xyz" = "ACC then "good" else "not good" end
    Case when "MF" = "M"  then "MAN" else "WOMAN" end
   ...
end

I kept getting "Incorrect syntax near the keyword 'case'

My first comment was for SQL

in your above statement, try change it as


Case when tmp1="ON" then "WRITE HERE WHAT YOU NEED"
    Case when "xyz" = "ACC then "good" else "not good"
    Case when "MF" = "M"  then "MAN" else "WOMAN"
   ...
end

If MF and xyz are field names, then they do not need quotes.

Try the following code:

 select case ucase(rtrim(tmp1))
              when 'ON' then  'He was'
                 case ucase(rtrim(xyz))
                 when 'ACC' then  'GOOD'
                 else 'NOT GOOD'
                 end
                 case ucase(rtrim(MF))
                 when 'M' then 'Male'
                 else 'Female'
                 end
                 case ucase(rtrim(NAMEX))
                 when null then 'Not give'
                 else 'FIRSTNAME: '+trim(NAMEX)
                 end
                 case ucase(rtrim(ADDRESSX))
                 when null then 'Not Give'
                 else 'Address IS: '+trim(ADDRESSX)

Sorry, but all posts given yet are missing some text and contain several syntax errors.
select
  case when upper(rtrim(tmp1)) = 'ON' then      
    '<b>Sample :</b> He was ' 
    + case when upper(rtrim(xyz)) = 'ACC'
           then '<b>GOOD</b> '
           else '<b>NOT GOOD</b> '
      end
    + case when upper(rtrim(MF))  = 'M'
           then 'MAN: <b>Male</b> '
           else 'WOMAN: <b>Female</b> '
      end
    + case when upper(rtrim(NAMEX)) != ''
           then 'FIRSTNAME: <b>' + rtrim(NAMEX) + '</b> '
           else 'FIRSTNAME: <b>Not give</b> '
      end
    + case when upper(rtrim(ADDRESSX)) != ''
           then 'Address IS: <b>' + rtrim(ADDRESSX) + '</b> '
           else 'Address: <b>Not Give</b> '
      end
    + '</td></tr>'
   end
from ...

this is what I used

case when upper(rtrim(tmp1)) = 'ON' then  ' He was '
    + case when upper(rtrim(xyz)) = 'ACC'
           then 'GOOD'
           else 'NOT GOOD< '
etc.

While the (now) accepted answer http:#a33649798 is correct, it is very generic. You originally accepted 4 answers (see http:/Q_26479861.html for the objection containing the split you initiated).

While I do not want to force you to accept any answer you do not want to, both outcomes seem to be inappropriate. To be honest, only the first (very generic) and my answer should get points, because everything else was just not appropriate for very obvious reasons. http:#a33652294 was very close, though syntactically wrong in several ways.

If you return to the split as done first, different points should be awarded - very generic and only partitially correct solutions should get a small share, and only if they contributed to the solution. The main points usually go to the *correct* answer.

I have requested attention for review (again). I'm sorry that it is so difficult to accomplish a proper and peaceful close here.

I am agree that http:#a33649798 was a vry general asnwer and http:#a33652294 was trying to point the specific case. Asker should select whatever he use for solving his problem. Even none of above question answered his query, then he should close/delete this question. But overall you cannot say that http:#a33649798 is wrong, and it was the first answer.

Thank you for posting how you resolved the issue. I am sure it will be helpful users. In my opinion, that is more important than who gets the most points for helping. :-)
