您可以设置订单以保留序列。

SELECT ID, CompanyDetails
FROM (
    SELECT ID, CompanyName AS CompanyDetails, 1 AS Ord
    FROM #table
    UNION
    SELECT ID, VendorName, 2 AS Ord
    FROM #table


) A
ORDER BY ID, Ord

Answer 5

通过使用交叉应用和NTile，我们也可以实现

 Select ID,CompanyDetails 
        from (
Select NTILE(6)OVER(PARTITION BY COL ORDER BY COL DESC )ID ,
T.VAL As CompanyDetails 
            from (
select COL,VAL from  #Table1
CROSS APPLY(VALUES 
    ('Vendorname',[Vendor Name]),
    ('CompanyName',[CompanyName]))CS(COL,VAL))T)TT
    ORDER BY ID
