Answer 1

根据我的要求，您需要汇总每个月的一些列。你可以用这个：

更新2：

SELECT TRUNC(RGS_DTM, 'MM'), COUNT(PKG_SNO) STUDENT_PKG_COUNT, COUNT(SHARED) SHARED_COUNT, COUNT(NON_SHARED) NON_SHARED_COUNT

FROM (SELECT PKG_SNO,
             CASE WHEN SHAR_YN = 1 THEN PKG_SNO END SHARED,
             CASE WHEN SHAR_YN = 0 THEN PKG_SNO ENDNON_SHARED
      FROM lrms.v_lrpm_pkg
      WHERE USE_YNDCD = 1
           AND MNGT_PRDN_YN = 'N'
           AND PARN_PKG_SNO = 0
           AND TO_CHAR(RGS_DTM, 'YYYY.MM.DD') BETWEEN #startDt# AND #endDt#)
GROUP BY TRUNC(RGS_DTM, 'MM')

Answer 2

按年份和月份分组将起到作用

group by YEAR(yourdae),MONTH(yourdate)

如何在日期查询中将数据汇总成一个？
