More, these values are replaced in a such way that you can pass really large data (megabytes) using this approach, that is limited when passing data directly as a constant. This way is very useful for saving General and large Memo field data.

This is correct, but you can write one :-)

Also, take a look to @@IDENTITY. If you have no triger on that table that does other inserts (and there are no plans to create such triggers), @@IDENTITY is better in you case.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
