A recent discussion on the subject of SQL with Zigster and other friends has let me to this question:

With all the sub selecting, maxing, having and grouping and other such SQLisms associated with quite complex queries, wouldn't it just be easier to select the lot into perl (row by row or otherwise) and do the processing there? Assuming, that is, (or maybe not) that the program receiving the data was perl anyway.

As there will be many factors, here are some points raised:

Would it be:

I have not benchmarked this, but my hunch says all of the above.

How would it fair if there was one or many tables involved?

Would it depend on the database?

In some cases, I imagine it would be vlaid to completely remove the database and replace it with flat files.

Another hunch of mine say that it will simpy come down to "it depends what you are doing". But that would be a shame.

Your thoughts would be appreciated.
