Question

I read a lot about this but I found it hard to implement, since I never used cursor and pivot is not available in SQL Server 2000, I hope someone here can help me, thanks.

Answer 1

Since SQL Server 2000 does not have the PIVOT function, you should be able to use something similar to the following:
DECLARE #query AS NVARCHAR(4000)
DECLARE #rowCount as int
DECLARE #pivotCount as int
DECLARE #pivotRow as varchar(10)
set #rowCount = 1
set #pivotRow = ''
create table #colsPivot
(
id int IDENTITY(1,1),
name varchar(20),
CustId int
)
insert into #colsPivot
select 'Observacion', IDObservacionCustomer
from yourtable
set #pivotCount= (select COUNT(*) from #colsPivot)
-- reset rowcount
set #rowCount = 1
set #query = ''
---- create the CASE string
while #rowCount <= #pivotCount
begin
set #pivotRow = (select Top 1 CustId from #colsPivot)
set #query = #query + ', max(case when IDObservacionCustomer = ''' + #pivotRow + ''' then Observacion end) as ''Observacion_' + cast(#rowCount as varchar(10)) + ''''
delete from #colsPivot where CustId = #pivotRow
if #rowCount <= #pivotCount
begin
set #rowCount = #rowCount + 1
end
end
-- add the rest of the SQL Statement
set #query = 'SELECT IDProspecto ' + #query + ' from yourtable group by IDProspecto'
exec(#query)

Answer 2

You can try this example.
Prepare data:
create table tab1
(
IDProspecto int,
IDObservacionCustomer int,
Observacion varchar(130)
)
insert into tab1
values (2204078,275214 ,'03/9 Hable con Claudia me informa que Roberto ya se termino le deje..' )
insert into tab1
values (2204078,294567 ,'19/09 SOLICITAN LLAME MAÑANA A ALEJANDRO ' )
insert into tab1
values (2204078,295310 ,'20/09 se envia mail a adrian' )
insert into tab1
values (2204078,304102 ,'CIA SOLICITA NO INSTALE EQUIPO' )
We need identity field, so I create new table, and copy data from tab1.
create table tab2
(
id int identity,
IDProspecto int,
IDObservacionCustomer int,
Observacion varchar(130)
)
insert into tab2(IDProspecto,IDObservacionCustomer,Observacion)
select IDProspecto,IDObservacionCustomer,Observacion from tab1
Run query:
declare #max int, #inc int, #SqlSel varchar(2000),#SqlJoin varchar(2000), #Sql varchar(2000)
select #max = max(cnt) from (
select count(1) as cnt
from tab1
) T
select #inc = 1
select #SqlSel = 'select distinct t.IDProspecto '
select #SqlJoin = 'from tab2 t'
while #max>=#inc
begin
select #SqlSel= #SqlSel+', tab2'+convert(varchar,#inc)+'.Observacion as o'+convert(varchar,#inc)
select #SqlJoin = #SqlJoin+' left join tab2 as tab2'+convert(varchar,#inc)+' on t.IDProspecto = tab2'+convert(varchar,#inc)+'.IDProspecto and tab2'+convert(varchar,#inc)+'.id='+convert(varchar,#inc)
select #inc=#inc+1
end
select #SqlSel, #SqlJoin
exec( #SqlSel+' '+ #SqlJoin)
