如何从查询中删除 CubeJS 默认的 Group By 子句

How to remove CubeJS default Group By clause from query

CubeJS 默认应用 Group By 子句,当我们 运行 任何查询时。

例如下面是我的 JSON 员工 Cube 查询:

{
  "dimensions": [
    "Employee.date",
    "Employee.state",
    "Employee.id"
  ],
  "timeDimensions": [],
  "filters": []
}

当我在 CubeJS 中 运行 以上 JSON 查询时,它将 运行 以下 SQL:

SELECT
  `employee`.updatedAt `employee__date`,
  `employee`.state `employee__state`,
  `employee`.EmpId `employee__id`
FROM
  DEMO.Employee AS `employee`
GROUP BY
  1,
  2,
  3
ORDER BY
  1 ASC
LIMIT
  10000

下面的参考是 Employee 我拥有的 Cube :

cube(`Employee`, {
  sql: `SELECT * FROM DEMO.Employee `,
  title: `Employee`,

  measures: {
    count: {
      type: `count`
    }
  },
  dimensions: {
    id: {
      sql: `EmpId`,
      type: `string`
    },
    date: {
      sql: `updatedAt`,
      type: `time`
    },
    state: {
      sql: `state`,
      type: `string`
    }
  }
});

如果我期望低于 SQL,我需要创建的 JSON 查询是什么:

SELECT
  `employee`.updatedAt `employee__date`,
  `employee`.state `employee__state`,
  `employee`.EmpId `employee__id`
FROM
  DEMO.Employee AS `employee`
WHERE
  `employee`.updatedAt ` BETWEEN '2019-01-01' AND '2019-05-01'
LIMIT
  10000

有什么方法可以从 CubeJS 本身生成的 SQL 查询中删除 Group By 子句。

自 0.10.62 以来有 ungrouped 查询 属性:https://cube.dev/docs/query-format#query-properties。在您的情况下,可以使用以下查询:

{
  "dimensions": [
    "Employee.date",
    "Employee.state",
    "Employee.id"
  ],
  "timeDimensions": [],
  "filters": [],
  "ungrouped": true
}
