Drupal - Where is the content of a node's body stored?
In Drupal 7 the body has been moved to the field_data_body table.
I don't have a running drupal installation here, but I asked myself this very question a couple of weeks ago, and it took time to find the answer.
If I remember correctly, the body of the node is stored in the table that is used to keep the "revisions" of the node. I am not sure what its name is, but it should be something like "node_revision" or "node_revisions."
It's the "node_revisions" table, in Drupal 5.
