I didn't say that javax.mail is dependent on bouncycastle. I just presented my scenario. :). Yes, createMDNData() uses some MIME type which is handled by bouncycastle. (more) |

@Alexei In my case, I think this wouldn't be recommendable, even if I shouldn't stick with SQL. Anyway, taking 100K rows form DB to parse them on the middleware seems to me not a good idea. I think this should be done on the DB side.
Your SQL is quite useful for me except the recursivity limitation.... (more) |

@Alexei 'this type of query might be better be done in a language/framework like C++, Java or .NET'. Yes, I'm forced to remain to SQL. But do you mean to use an ORM or do you mean to make the logic from such a framework? I ask because second option seems to me not efficient. (more) |

| Question | — |
How to break infinite loop in CTE I have a parent-child relation in my table, with possibly circular cases. Is it possible to break the infinite recursion in CTE checking values of all previous rows? I would need something like this: with mycte(childId, parentId, col1) AS ( SELECT r.childId, r.parentId, r.col1 FROM... (more) |
