Answer 1

테이블 정의를 알 수 없으므로 쿼리를 구문 분석하지 않습니다. 그러나 문제는 거의 확실 개념적으로, 당신은 같은 것을 가지고있다 :

CASE 
    WHEN Condition 1 THEN <decimal value> 
    WHEN Condition 2 THEN <string value> 
END 

문제를 CASE표현이 하나의 잘 정의 된 데이터 형식의 결과를 가지고 있어야한다는 것입니다. THEN 절은이 단일 유형의 값을 반환하거나 변환해야합니다.

형식이 혼합되어 있으면 SQL Server는 다양한 우선 순위 규칙을 사용하여 형식을 선택합니다. 이 경우 숫자 형식으로 선택되며 문자열을 숫자로 변환하지 못합니다.

일반적인 방법이 될 것입니다 해결하기 위해 :

CASE 
    WHEN Condition 1 THEN CONVERT(varchar(200),<decimal value>) 
    WHEN Condition 2 THEN <string value> 
END 

이제 SQL 서버는 문자열로 모든 것을 유지합니다.
