SSIS ##tmptable is dropped when execute SQL task is executed - sql-server

Question

Before you say me,
I put retainsameconnection, I had put.
and I have delay validation on ALL my components too
after in others query where I use this dynamic temp table
this fails (sometimes) saying temp table does not exist.
How can I solve it?
This is my query..
declare #usuario varchar(100)
declare #contra varchar(100)
declare #servidor varchar(100)
declare #based varchar(100)
declare #nombretabla varchar(100)
set #usuario ='pruebas'
set #contra ='123'
set #servidor ='1.6.7.9'
set #based ='op'
set #nombretabla='tablaBC245B7A910D4B488CC9EFF0EFD3C177'
/*this was a dynamic name got with this query in other execute sql task
declare #tabla varchar(50)
set #tabla=NEWID ()
set #tabla =REPLACE (#tabla ,'-','')
select 'tabla'+#tabla nombre
*/
declare #cadena varchar(500)
set #cadena ='SERVER='+#servidor+';DataBasE='+#based +
';uid='+#usuario +';pwd='+#contra+';'
set #cadena =''''+#cadena +''''
while OBJECT_ID('tempdb..##envases'+#nombretabla) IS NULL
begin
exec('
SELECT * into ##envases'+#nombretabla+'
FROM OPENROWSET(
''SQLNCLI'',
'+#cadena+',
''
select pro=p.pro,envase=e.pro from procorp p
join procorp e on p.envase=e.envase and e.esenvase=1
union all select pro=-1,envase=-1
'')
'
)
end
IF OBJECT_ID('tempdb..#primera') IS NOT NULL DROP TABLE #primera
IF OBJECT_ID('tempdb..#end') IS NOT NULL DROP TABLE #end
create table #primera(
pro int,
envase int
)
insert into #primera
exec('select * from ##envases'+#nombretabla+'')
select fila='select pro='+CONVERT(varchar(10),pro)+
', envase='+CONVERT(varchar(10),envase)+' union all '
into #end
from #primera
--select * from #end
--drop table #end
--drop table #primera
alter table #end
add
uno int not null default(1),
id int identity
declare #maximo int
set #maximo =(select MAX(id) from #end )
update #end set fila=fila+'terminado' where id=#maximo
update #end set fila=replace(fila,'union all terminado','') where id=#maximo
select uno, ' begin try drop table #tmpenvase end try begin catch end catch
select * into #tmpenvase from ( '+
convert(varchar(max),STUFF(
(select '', convert(varchar(max),fila) from #end order by id
for xml path('') )
,1,0,'') )+' ) q 'cadena
from #end e
group by uno

Answer 1

I would use standard SSIS objects for this.
I cant really follow what the end objective of your script is, but generally:
Connection strings can be managed using Configuration files, Variables and other means.
Within Data Flow Tasks, OLE DB Source Transformations can run SELECT statements, OLE DB Destinations can deliver data, OLE DB Commands can run UPDATE statements.
I would reimagine your requirements in terms of a series of tasks, rather than trying to force everything into a single T-SQL script.

Global temporary tables are visible to any user and any connection after they are created, and are deleted when all users that are referencing the table disconnect from the instance of SQL Server.
According to that paragraph of SQL Server Books-Online; as soon as SQL Server don't found any connection to a global temporary tables those temporary tables will deleted, and when you are create a local temporary table with EXEC command SQL Server will delete that local temporary table this will also applied to a global temporary table but after a checking for all users connections and so on. I think sometimes SQL Server found your global temporary table alone before the your next statement commits.
I suggest you to use local table variables and use INSERT EXEC to fill them.
And also there are some other ways too.
