Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Old versions of the SQL standard (SQL-92) only allowed sorting by output column name or number. The current version of RDMSs are fine.
What's wrong with it? It's supported by all SQL implementations which I know. In oposite to aliases, which are supported only in some of them.
Hey shvetsovdm, thanks for the notes I really appreciate. You are right, I will do this way in the next time.
Peace!
