  Nov 19, 2012 06:57 AM|LINK

  my table contain 3 column (id, seq. no and creation date)

  how can i filter the max. creation date of each seq. no ,make sure that each seq. no. only has 1 record in result set in ORacle package

  for example

  id seq_no   create_date 1  1        11-09-2012 2  1        18-09-2012 3  2        11-09-2012

  Oracle analytics with windowing functions can do that.

  Show us a sample set of data like 10 lines, and your desired output for those 10 lines,

  and we can show you Oracle Analytics.

  Or you can read about Oracle Analytics in many places online or books, like the chapter on the subject in:

  http://www.amazon.com/Oracle-Database-11g-SQL-Press/dp/0071498508/ref=sr_1_2?s=books&ie=UTF8&qid=1353562612&sr=1-2&keywords=oracle+sql
