Hi there, I am trying to diff the new version against the one version older record and extract the diff from them. For example, ver 1.3 against 1.2 and ver 1.2 against 1.1 to only extract the diff between them. I hope to do it in a flexible ways as in future I may have ver 1.4 and so on... I also want to limit the results to only latest 5 version diff. For example, I got 1.1, 1.2, ..., 1.10 version, but I only want the result for 1.6, 1.7, ..., 1.10 when diff against the previous one version. Is that possible? Currently I have data like this: records: ============================================ index=a, ver=1.1, a="halo", b="haha", c="nana" index=a, ver=1.1, a="testing", b="haha", c="nana" index=a, ver=1.1, a="halo", b="kaka", c="testing" index=a, ver=1.2, a="halo", b="haha", c="nana" index=a, ver=1.2, a="lala", b="haha", c="nana" index=a, ver=1.2, a="halo", b="kaka", c="TESTING" index=a, ver=1.3, a="halo", b="haha", c="nana" index=a, ver=1.3, a="lala", b="haha", c="tata" index=a, ver=1.3, a="halo", b="kaka", c="lala" index=a, ver=1.3, a="halo", b="kaka", c="kakaka" ============================================ Result expected when comparing ver 1.2 against 1.1 and ver1.3 against 1.2: ver added record (merging a b c using ",") removed record (merging a b c using ",") 1.2 lala,haha,nana halo,kaka,TESTING testing,haha,nana halo,kaka,testing 1.3 lala,haha,tata halo,kaka,lala halo,kaka,kakaka lala,haha,nana halo,kaka,TESTING
