Sql 使用重复的值透视表-可能吗？
我有一个表-Sql 使用重复的值透视表-可能吗？,sql,oracle,excel,vba,Sql,Oracle,Excel,Vba,我有一个表-费率，如下所示： LOCATION_ID RATE_TYPE_CODE RATE_1 START_DATE END_DATE ----------- -------------- ---------- ---------- --------- 1 A .04 30-JUN-15 1 A .02 01-JUL-15 30-JUN-16

from rate r
where ( r.start_date is null
or r.start_date <= to_date ('01-APR-2016')
or r.start_date >= to_date ('01-APR-2016')

我认为这样一个支点是可能的，但我看不出有什么办法。在此方面的任何帮助都将不胜感激。我找到了一个可以接受的答案：
