Возникли проблемы с @variable и Cursor в SQL 2008

Question

- Не уверен, что я делаю это правильно, за исключением того, что я делаю, не работает.У меня есть список (vend_num), который мне нужен для выполнения запроса по одному и компиляции результатов.Если кто-нибудь может увидеть / объяснить, где я сошел с рельсов, это было бы очень признательно.Я прочесываю Интернет и этот сайт и не могу обернуть его вокруг себя.

--drop table ##ENE_vendUpdate

begin            
    drop table ##ENE_vendUpdate          
end  

select vend_num             
into ##ENE_vendUpdate
from vendor 
--select * from  ##ENE_vendUpdate

Ваш TSQL не выглядит завершенным.Это должно выглядеть примерно так:

DECLARE warrwebcur CURSOR FOR
select vend_num from ##ENE_vendUpdate

OPEN warrwebcur
FETCH NEXT FROM warrwebcur INTO @vend_num

WHILE @@FETCH_STATUS = 0  
BEGIN  
      -- your query
      FETCH NEXT FROM warrwebcur INTO @vend_num
END 

CLOSE warrwebcur 
DEALLOCATE warrwebcur
