python - GQL（谷歌应用引擎）中的OR条件返回错误为什么？

Question

当我在 GQL 中使用 OR 条件时，它返回错误消息“ BadQueryError: Parse Error: Expected no additional symbols at symbol OR。为什么？

db.GqlQuery("Select * from vendor where access='public' OR organisation_id='"+ orgid +"'")

Answer 1

    GQL does not have an OR operator. However, it does have an IN operator, 
which provides a limited form of OR.

Docs 明确表示 GQL 没有 OR 运算符。

你可以做这样的事情......进行两个查询并组合结果......

  vendors=vendor.all()
  pub_vendors = vendors.filter("access = ","public")
  vendors=vendor.all()
  org_vendors = vendors.filter("organisation_id = ",orgid)
  results = pub_vendors.extend(org_vendors)
