dit document beschrijft de databank in Drupal

1. node: unieke node_id (nid)
2. node_field_data: metadata over node (aanmaak-, wijzigingsdatum, …)
3. node_body: inhoud
4. node_revison: nid, vid
5. node_field_revision: metadata over node (aanmaakdatum, userid)
6. node_revision_body: inhoud revisie
7. users: overzicht gebruikers
8. users_field_data: detail over gebruikers (naam, email, userid, …)
9. node_field_<naam>: velden die je gebruikt binnen je node.

elke node heeft data in onderstaande tabellen

• node: nid, type (content type)
• node_body: eigenlijke inhoud van de node
• node_field_data: metadata over node: oa titel
• node_revision: info over revisies
• node_revision_body: inhoud van elke revisie
• node_field_revision: metadata over revisies

ahv volgende functies:

• FROM_UNIXTIME(<timestamp>):unixepoch in human-readable
• NOW(): huidige datum
  SELECT NOW()
• INTERVAL xx HOUR/DAY/MONTH/YEAR: xx uur/dagen/maanden/jaar seconden vroeger (-) of later (+)
  SELECT NOW() - INTERVAL 1 HOUR: 1 uur geleden
• YEAR(<timestamp>): vis het jaar uit de timestamp
  SELECT YEAR(FROM_UNIXTIME(created)) FROM l7gh_node_field_data
• MONTH(<timestamp>): vis de maand uit de timestamp
  SELECT MONTH(FROM_UNIXTIME(created)) FROM l7gh_node_field_data
• DAY(<timestamp>): vis de dag uit de timestamp
  SELECT DAY(FROM_UNIXTIME(created)) FROM l7gh_node_field_data
