DB2 SQL:选择值与前一个不同的行
Let's say I have a table (PERSON) like this :
I would like to select only the rows where the value of column "C" has changed from previous row.
In this case, I should get : rows 1, 4, 5, 7, 8, 9 and 15.
I can't figure out how to achieve this.
Does someone has an idea please ?
Thank you
