当我运行此查询时，它应该在DAY列（210301,201302，SUM）下显示3行结果。但由于某种原因，它只显示DAY列下的SUM行。想法是'201301'行在1月累积了31天的数据。 谁能指出我为什么不出现？

答案 0 :(得分：1)
这可能是因为和字段TOT_CNT
中的空值更改行
MNOT.SUM_STD_CNT + RSC.MOVIE_500K + RSC.MOVIE_1M + RSC.MOVIE + RSC.EXAM + RSC.WEB + RSC.IMG + RSC.INTERRAC + RSC.DOC TOT_CNT
到
nvl(MNOT.SUM_STD_CNT,0) + nvl(RSC.MOVIE_500K,0) + nvl(RSC.MOVIE_1M,0) + nvl(RSC.MOVIE,0) + nvl(RSC.EXAM,0) + nvl(RSC.WEB,0) + nvl(RSC.IMG,0) + nvl(RSC.INTERRAC,0) + nvl(RSC.DOC,0) AS TOT_CNT
