Answer 1

SELECT 
    SUBSTRING(ProductDescription, 1, 
     CHARINDEX(' - ', ProductDescription) - 1 
    ) AS Field1, 
    SUBSTRING(ProductDescription, 
     CHARINDEX(' - ', ProductDescription) + 3, 
     CHARINDEX(' - ', ProductDescription, 
      CHARINDEX(' - ', ProductDescription) + 3 
     ) - (CHARINDEX(' - ', ProductDescription) + 3) 
    ) AS Field2, 
    SUBSTRING(ProductDescription, 
     CHARINDEX(' - ', ProductDescription, 
      CHARINDEX(' - ', ProductDescription) + 3) + 3, 
     LEN(ProductDescription) 
    ) AS Field3, 
    ProductDescription 
FROM your_table 

Answer 2

그렇게하지해야한다입니다 왜 이런 식으로하고 싶은지 알지만 샘플 용으로 사용할 수 있습니다.

SELECT 
    substring(section,1,3) as column1, 
    CASE WHEN LEN(section)<5 THEN '0' 
    ELSE 
    SUBSTRING(section,5,1) 
    END as column2 
FROM MyTable 

Answer 3

SELECT 
    substring(column1,1,3) as column1, 
    CASE WHEN PATINDEX('%[0-9]%',RTRIM(SUBSTRING(column1,4,7)))=0 THEN '0' 
    ELSE 
    SUBSTRING(column1,5,1) 
    END as column2, 
    --RTRIM(SUBSTRING(column1,7,43))as column3 
    CASE WHEN PATINDEX('%[0-9]%',RTRIM(SUBSTRING(column1,4,7)))!=0 
    THEN RTRIM(SUBSTRING(column1,7,43)) 
    ELSE 
    RTRIM(SUBSTRING(column1,5,43)) 
    END as column3 
FROM MyTable
