  Hi guys!,

  As the tittle says, i´m having some trouble on a dynamic pivot. Let´s cut to the chase.

  First I set the columns i will use

  declare @analista varchar (100)

  declare @loteInicio int

  declare @loteFin int

  declare @Matriz varchar (2)

  set @analista = 'Veronica Villanueva'

  set @loteinicio = 472800

  set @lotefin = 472880

  declare @columnas varchar(max)

  set @columnas = ''

  select @columnas = coalesce(@columnas + '[' + cast(paraid as varchar(12)) + '],', '')

  FROM (

  select distinct

  b.paraid

  from lotes a

  join analisis b on a.codigo = b.anaid

  join sample_analysis c on a.lotes = c.lote

  where a.estado_l <> 'aprobado'

  and c.sample_number not like '%R%'

  and a.analista_l = @analista

  and (a.lotes >= @loteInicio or a.lotes <= @loteFin) ) as parid

  set @columnas = left(@columnas,LEN(@columnas)-1)

  print @columnas

  The output is the desired;

  [Br ],[CID ],[CIT ],[Cl ],[Conduc],[COT ],[F ],[Fosfat],[Langue],[Nitrat],[Nitrit],[Ntotal],[Ortof ],[Sulf ],[Sulfat],[SulfDi]

  No problem so far.

  Then i pivot;

  DECLARE @SQLString nvarchar(500);

  set @SQLString = N'

  select *

  from

  (select a.lotes,b.paraid,a.analista_l,c.sample_number

  from lotes a

  join analisis b on a.codigo = b.anaid

  join sample_analysis c on a.lotes = c.lote

  where a.estado_l <> ''aprobado''

  and c.sample_number not like ''%R%''

  and a.analista_l = ''@analista''

  and (a.lotes >= ''@loteInicio''

  or a.lotes <= ''@loteFin'')

  ) as ST

  pivot

  (

  sum(lotes)

  for paraid in ('+@columnas+')

  ) as PivotTable;'

  set @SQLString = replace(replace(replace(@SQLString,'@analista',@analista),'@loteinicio',@loteinicio),'@lotefin',@lotefin)

  EXECUTE sp_executesql @SQLString

  and i get the following error;

  Mens. 105, Level 15, State 1, Line 17

  Unclosed quotation mark after the character string 'O'.

  Mens. 102, Level 15, State 1, Line 17

  Incorrect syntax near 'O'.

  I don´t understan why is giving me this message. I know that is bound to the 'ortof' column i pivoted.

  Suggestions??ideas??

  thanks in advance!!!

  If you're already using sp_executesql, you should parametrize your query to avoid SQL Injection. You might have a Bobby Tables[/url] in your database.
