는 SQL Server의 BCP와 스칼라 변수를 선언해야합니다

Question

나는이 다음 내 저장 프로 시저 코드의 섹션 어떤 이유로, 나는 오류 메시지가 계속 :

1. 하는 스칼라 변수 "@query"를 선언해야을
2. 문 (들) 나는 또한 파일과 @query 문자열로 내보낼 BCP를 사용하려고 시도하고

을 준비 할 수없는 것은 복잡한 문자열입니다. 코드는 다음과 같습니다.

@market varchar(20) = null, 

@date datetime = null 


AS 
BEGIN 
    SET NOCOUNT ON; 

set @date = 

CASE datepart(dw,getdate()) 

WHEN 1 THEN dateadd(day, -1, convert(varchar, getdate(), 101)) 

WHEN 2 THEN dateadd(day, -2, convert(varchar, getdate(), 101)) 

WHEN 3 THEN dateadd(day, -3, convert(varchar, getdate(), 101)) 

WHEN 4 THEN dateadd(day, -4, convert(varchar, getdate(), 101)) 

WHEN 5 THEN dateadd(day, -5, convert(varchar, getdate(), 101)) 

WHEN 6 THEN dateadd(day, +0, convert(varchar, getdate(), 101)) 

WHEN 7 THEN dateadd(day, -7, convert(varchar, getdate(), 101))

queryout "C:\bcptest.txt" -T -c -t,' 

PRINT @query 

EXEC xp_cmdshell 'bcp @query queryout "C:\bcptest.txt" -T -c -t,' 



END 

Answer 1

@DBNull입니다. (4000) 당신은

SET @query = 'bcp "' + @query + '" queryout "C:\bcptest.txt" -T -c -t,'; 
EXEC xp_cmdshell @query; 

당신은 따옴표에서 쿼리를 포장 할 필요가 .... 이런 식으로 뭔가에 bcp 명령의 실제 실행을 변경해야하고, VARCHAR (8000) 또는 NVARCHAR의 제한이 실제 명령에서 xp_cmdshell을 사용하여 실행할 수 있습니다. 보기 또는 저장 프로 시저에서 쿼리를 래핑하는 것이 좋습니다. 이는 코드의 유지 보수성을 크게 향상시킬뿐만 아니라 크기 제한에 대해 걱정할 필요가 없으며 현재 수행해야하는 모든 단일 인용문은 물론입니다.

희망이 있습니다.
