Thread: sorted results after merge join?

    Default sorted results after merge join?

    Hi,

    I am sorry if this question already answered before. I did a search in the forum and could not find out anything related to this.

    I just wonder whether the output of a merge join will be sorted or not on the same keys which we used before the join step? Also can we use the output of a merge join step as an input of another merge join without sorting if the keys on both joins are the same.

    thanks

    The output will be sorted, so you don't have to sort again :-)
