复杂记录订阅

在以下示例中，我们有一个名为 students 的表，其中包含诸如 id、firstName、email、age 等字段和关系。

使用过滤器的订阅

您可以使用 Archie Core 自动生成的 GraphQL 订阅操作来订阅正在创建、更新和删除的单个和相关记录。

可用运算符

运算符	用法示例
eq	status = "active"
neq	type != "admin"
gt	age > 18
lt	price < 100
gte	score >= 80
lte	attempts <= 3
contains	name contains "john"
startsWith	email startsWith "admin"
endsWith	domain endsWith ".com"
