您可以使用下面的查詢來獲得上述結果。

DECLARE @Table TABLE(ID VARCHAR(10)); 
INSERT INTO @table(ID) VALUES ('320'),(332),(333),(334),(335); 
SELECT mt.ID, 
    STUFF(( 
     SELECT ', ' + ID 
     FROM @table t 
     WHERE t.ID <= mt.ID 
     FOR XML PATH('')), 1, 2, '') AS oldersequence 
FROM @table mt 
ORDER BY ID
