Hello,

I need to transpose the information in a table and substitue words for letter abreviations, basically taking sevral rows of data and putting it into one row/column.  

Here is a sample of the information in my DB currently...

[Bird ID]            [Defects]
-----------------------------------
365965544         Slight Legs
365965544         Toes
365965545         Slight Legs
365965545         Toes
365965549         Severe Legs
365965549         Severe Toes
365965551         Slight Legs
365965553         Slight Legs

Here is what i want to turn it into...

[Bird ID]            [Defects]
-----------------------------------
365965544         SL, T
365965545         SL, T
365965549         SL, ST
365965551         SL
365965553         SL

Thanks!

what are the exact rules for the transformation fo  [Defects] into the short version?


in short:

create function dbo.concate_itemid ( @birdid )
returns varchar(8000)
as
begin
  declare @res varchar(8000)
  select @res = coalesce( @res + ',' , '') + defects
  from yourtable where [bird id]= @birdid
  return (@res)
end


and use it like this

select [bird id], dbo.concate_itemid([bird id])
from yourtable
group by [bird id]

I think this will work great.  I can add a case statement to replace the string with letter abbreviations, unless you know a better way?

Here is what I got it is working good for me, Thank You!! (I need to add the rest of the letter replacements in)


create function dbo.concate_itemid ( @birdid int )
returns varchar(8000)
as
begin
  declare @res varchar(8000)
  select @res = coalesce( @res + ',' , '') + case when defect = 'Slight Legs' then 'SL' else defect end
  from Defects where [bird id]= @birdid
  return (@res)
end

GO

select [bird id], dbo.concate_itemid([bird id])
from defects
group by [bird id]

I would, instead of doing it in the code, have a "translation" table of the values and the replacements...

you might also try to do it automatically, by extracting all the characters after a space...

create function dbo.GetShortValue ( @d varchar(100) )
returns varchar(100)
as
begin
  declare @res varchar(100)
  declare @x int

  set @res = substring(@d, 1,1)
  set @x = 2
  while (@x > 0)
  begin
    set @x = charindex(@d, ' ' , @x)
    if (@x>0)
    begin
      set @res = @res + substring(@d, @x+1, 1)
      set @x = @x +2
    end      
  end      

  return (@res)
end

and use it like this:


create function dbo.concate_itemid ( @birdid int )
returns varchar(8000)
as
begin
  declare @res varchar(8000)
  select @res = coalesce( @res + ',' , '') + dbo.GetShortValue (defect )
  from Defects where [bird id]= @birdid
  return (@res)
end
