下文将教您在数据库中如何使用SQL查询连续号码段的方法,供您参考,如果您对SQL查询方面感兴趣的话,不妨一看,对您会有所帮助。
有一个表结构,
fphm,kshm
2014,00000001
2014,00000002
2014,00000003
2014,00000004
2014,00000005
2014,00000007
2014,00000008
2014,00000009
2013,00000120
2013,00000121
2013,00000122
2013,00000124
2013,00000125
(第二个字段内可能是连续的数据,可能存在断点。)
SQL> SELECT b.fphm, MIN (b.kshm) Start_HM, MAX (b.kshm) End_HM 2 FROM (SELECT a.*, TO_NUMBER (a.kshm - ROWNUM) cc 3 FROM (SELECT * 4 FROM t 5 ORDER BY fphm, kshm) a) b 6 GROUP BY b.fphm, b.cc 7 / FPHM START_HM END_HM ---------- -------- -------- 2013 00000120 00000122 2013 00000124 00000125 2014 00000001 00000005 2014 00000007 00000009 查询结果:
2014,00000001,00000005
2014,00000009,00000007
2013,00000120,00000122
