如何在CubeJS的JSON查询中通过度量获取COUNT条记录返回

Question

I want to get a count of records return by the below JSON query of CubeJS.

{
  "measures": [
    "Employee.salaryTotal"
  ],
  "timeDimensions": [
    {
      "dimension": "Employee.createdat"
    }
  ],
  "dimensions": [
    "Employee.isactive"
  ],
  "filters": []
}

This JSON query generates below SQL in CubeJS:

SELECT
  `employee`.`isActive` `employee__isactive`,
   SUM(salary) `employee__salary_total`
FROM
  DEMO.Employee AS `employee`
GROUP BY
  1
ORDER BY
  2 DESC
LIMIT
  10000

Output of SQL is:

+---------------------+------------------------+
|  employee__isactive | employee__salary_total |
+---------------------+------------------------+
| Y                   |                  17451 |
| N                   |                   1249 |
+---------------------+------------------------+

But what if I want count of records return by above SQL.
example:

SELECT COUNT(*) FROM 
    (SELECT
      `employee`.`isActive` `employee__isactive`,
      SUM(salary) `employee__salary_total`
    FROM
      DEMO.Employee AS `employee`
    GROUP BY
      1
    ORDER BY
      2 DESC
    LIMIT
      10000) AS EMPSAL

Expected result should be like this:

+------------+
| # COUNT(*) |
+------------+
|          2 |
+------------+

Currently there's no way to perform COUNT operation on top of final Cube.js query. If you're trying to implement paging functionality you can use offset and limit query parameters to check if there's a next page available by means of limit and row count comparison: https://cube.dev/docs/query-format#query-properties .
