Query to save 10 fields Using Drupal 7, I created a node with the 10 fields; these fields are inserted as a table. 

What query can I use insert the field values to the multiple tables, since multiple tables are the multiple fields?
Use the API: node_save().

Saving data directly to field tables is not possible, you shouldn't even consider this. There are many ways to import data into nodes, for example the Migrate or Feeds modules, if that's what you're after.
