In What table in Drupal is the current version of core (Drupal) stored?

In What table in Drup开发者_如何学Pythonal is the current version of core (Drupal) stored? I'm looking for a string like 6.2.3.

I don't see it in the system table.

6.2.3? Current is Drupal 6.15.
Answer: system table, seek name="system" row, unserialize "info" field, or seek text in this field text like "version";s:4:"6.15"
Also CHANGELOG.txt file you can investigate.
Also see any *.info file in modules folder.

Also look for this code in system.module: define('VERSION', '6.19');
