[edit] Overview

What MS Access calls "queries" are called "views" in MySQL, i.e. they pull data from existing tables and are themselves usable as data sources in much the same way that tables are (and in which result sets from functions are not).

Some common prefixes:

qryCbx_: queries used for filling comboboxes. The unique ID will always be the first field, and the text to display will always be the second field; additional fields may be provided for use in further qryCbx_ queries which show a subset of the results.
qryCat_: queries which build catalog numbers or information by joining multiple tables. (In Access, the convention was qryCatNum_.)

[edit] Restocks

all restock requests:
- /qryRstks_info
- /qryRstkReq_Item_Rcd_status
- /qryRstkReq_Item_status
  - /qryRstkReq_Item_status_Req_info
  - /qryRstkReq_Items_expected: show only expected items
- /qryCbx_RstkReq
  - /qryRstkReq_by_status
  - /qryRstkReq_by_PurchOrd
filtered by status:
- /qryRstks_active: not terminated = !(closed, orphaned or killed)
  - /qryRstkItms_active
    - /qryRstkItms_expected
      - /qryRstkItms_expected_byItem - grouped by ID_Item
  - /qryRstks_unsent: created but not ordered yet
    - /qryRstkItms_unsent
      - /qryRstkItms_unsent_for_order
- /qryRstks_inactive: all the rest

terminology

Active = not "terminated", i.e. not "closed", "killed", or "orphaned" (may or may not be "expected" yet)
Closed = received from supplier, nothing remaining on backorder
Expected = placed with supplier, but not yet received
Killed = canceled with supplier after having been placed
Orphaned = we don't have records that anything was received, but nothing further is expected (usually old data)
Terminated = closed, orphaned, or killed
Unsent = created but not yet placed with supplier, i.e. not "expected"

phases:

Time →
Created	(Unsent)	Ordered	(Expected)	Closed, Killed, or Orphaned
--(Active)--				--(Terminated/Inactive)--

[edit] old queries

This was the first batch of queries I created, before I had decided to go with the qry prefix as in Access.

[edit] Caching

Caching should only be used for catalog display.
