sql - 特殊情况下复制项目的正确 SQL 语句

Question

必须显示图片中的所有检查项目。

这是我的sql语句。

SELECT DISTINCT 
    c.code || ' - ' || c.description || ' - ' || s.num AS SearchColumn, 
    s.num AS Num,
    c.code AS Code,
    c.product AS Product,
    f.faciltyname AS FacilityName,
    f.facilityid AS FacilityID,  
    c.description AS Description,  
    c.Number AS Num
FROM Facility f 
    JOIN Code c ON f.codeid = c.codeid
    JOIN Structure s ON c.structureid = s.structureid 
WHERE searchcolumn > "" 
    AND ((c.product = 'PROD1' OR c.product IS NULL )) 
ORDER BY c.code ASC 

他们只是从代码中复制，num和productid（也有特殊情况），但实际上它有不同的facilityid和facility name，这是需要的
