sql - 使用每个 CSV 值创建行

Question

ID          Dates                                          Qty      Secs    DayPart

我如何在不使用 CTE 的情况下更改这些逗号分隔值并获得这样的结果，因为我在 SQL SERVER 2000 上，如果我们不使用循环则更好，因为稍后数据将是巨大的

尝试这个

SELECT          a.ID,
                SUBSTRING(',' + a.Dates + ',', n.Number + 1, CHARINDEX(',', ',' + a.Dates + ',', n.Number + 1) - n.Number - 1) AS [Value]
                , [Qty], [Secs], [DayPart]
FROM            Table1 AS a
INNER JOIN      master..spt_values AS n ON SUBSTRING(',' + a.Dates + ',', n.Number, 1) = ','
WHERE           n.Type = 'p'
                AND n.Number > 0 
                AND n.Number < LEN(',' + a.Dates + ',')

If you don't want use CTE or loops, try use approach with additional table of numbers:

See http://www.sommarskog.se/arrays-in-sql-2000.html#tblnum-core

Something like:

CREATE FUNCTION inline_split_me (@param varchar(7998)) RETURNS TABLE AS
   RETURN(SELECT substring(',' + @param + ',', Number + 1,
                    charindex(',', ',' + @param + ',', Number + 1) - Number - 1)
                 AS Value
          FROM   Numbers
          WHERE  Number <= len(',' + @param + ',') - 1
            AND  substring(',' + @param + ',', Number, 1) = ',')
