过滤列表查询

您可以过滤查询结果。在以下示例中,我们有一个名为 students 的表,其中包含诸如 createdAtfirstNameemailage 等字段和关系。

查询经过过滤的记录列表。请注意过滤器参数。

请求

query MyQuery1 {
students(
filter: {
createdAt: {
gt: "2025-12-01T13:00:00.000Z"
},
email: {
contains: "williams"
}
}
) {
items {
id
createdAt
firstName
email
}
}
}

响应

{
"data": {
"students": {
"items": [
{
"id": "97fb89ac-e0ad-44f5-b671-24a1b751287c",
"createdAt": "2025-12-02T05:03:17.180675Z",
"firstName": "John",
"email": "john.williams@example.com"
},
{
"id": "e25c4955-7ea7-4a83-a3de-d4c7427cc9fa",
"createdAt": "2025-12-04T14:18:15.955194Z",
"firstName": "Robert",
"email": "robert.williams@example.com"
}
]
}
}
}

条件过滤器使用 AND 和 OR 键。

指定 AND 时,所有过滤器对象必须返回真值。

请求

query MyQuery1 {
students(
filter: {
AND: {
email: {
contains: "johnson"
},
isActive: {
not_equals: false
}
}
}
) {
items {
id
createdAt
firstName
email
isActive
}
}
}

响应

{
"data": {
"students": {
"items": [
{
"id": "13fcb5bf-a8a4-4e55-860f-74f425944ec0",
"createdAt": "2025-12-04T20:30:58.586321Z",
"firstName": "Mary",
"email": "mary.johnson@example.com",
"isActive": true
}
]
}
}
}

指定 OR 时,至少一个过滤器对象必须返回真值。

请求

query MyQuery1 {
students(
filter: {
OR: {
firstName: {
equals: "Mary"
},
lastName: {
equals: "Williams"
}
}
}
) {
items {
id
