Stores a record per term per property per language. This table is very similar to / identical to wbt_item_terms, but for properties.
Part of the md_docs_storage_terms storage system.
Fields:
- wbpt_id - an auto increment field
- wbpt_property_id - numeric value of the item ID. So P64 # 64
- wbpt_term_in_lang_id - reference to the wbt_term_in_lang table
+----------------------+------------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+----------------------+------------------+------+-----+---------+----------------+
| wbpt_id | int(10) unsigned | NO | PRI | NULL | auto_increment |
| wbpt_property_id | int(10) unsigned | NO | MUL | NULL | |
| wbpt_term_in_lang_id | int(10) unsigned | NO | MUL | NULL | |
+----------------------+------------------+------+-----+---------+----------------+
Using an integer to represent the item identifier was a design decision allowing for smaller tables and faster querying.
Extra Indexes:
- UNIQUEÂ wbit_term_in_lang, wbit_property_id
- wbit_property_id
Example data:
wbpt_id | wbpt_property_id | wbpt_term_in_lang_id |
1 | 9 | 5678 |
6 | 9 | 1111 |
7 | 10 | 888 |
