I am using ncluster loader to load the records into aster database. In the begin script, I create temp table then I load the records from flat files to temp files and in the end script, I merge records from temp table to actual table. In my case, I see that I may get two records in the flat file out of which one could be insert and other could be update. If I use the merge, then it doesn't allow to have multiple actions on same target row. Is there way to achieve?
