如何在Cube.js过滤器查询中添加OR条件

Question

我想在的JSON查询中添加Cube.js或条件。但是，一旦我在过滤器中添加了一个条件，它总是在SQL中添加和条件。

下面是我正在尝试的JSON查询。

{
  "dimensions": [
    "Employee.name",
    "Employee.company"
  ],
  "timeDimensions": [],
  "measures": [],
  "filters": [
    {
      "dimension": "Employee.company",
      "operator": "contains",
      "values": [
        "soft"
      ]
    },
    {
      "dimension": "Employee.name",
      "operator": "contains",
      "values": [
        "soft"
      ]
    }
  ]
}

它在SQL查询下面生成。

SELECT
  `employee`.name `employee__name`,
  `employee`.company `employee__company`
FROM
  DEMO.Employee AS `employee`
WHERE
  `employee`.company LIKE CONCAT('%', 'soft', '%') 
             AND 
  `employee`.name LIKE CONCAT('%', 'soft', '%')
GROUP BY
  1,
  2;

如果我想在SQL下面生成Cube.js的JSON查询是什么？

SELECT
  `employee`.name `employee__name`,
  `employee`.company `employee__company`
FROM
  DEMO.Employee AS `employee`
WHERE
  `employee`.company LIKE CONCAT('%', 'soft', '%') 
             OR
  `employee`.name LIKE CONCAT('%', 'soft', '%')
GROUP BY
  1,
  2;

Answer 1

目前还没有提供对逻辑运算符的API支持。与此同时，有几种解决办法：

1. 定义模拟或行为的维度。在你的情况下

cube(`Employee`, {
 // ...

 dimensions: {
   companyAndName: {
     sql: `CONCAT(${company}, ' ', ${name})`,
     type: `string`
   }
 }
});

1. 定义段。这些也可以生成：https://cube.dev/docs/schema-generation

cube(`Employee`, {
  // ...

  segments: {
    soft: {
      sql: `${company} LIKE CONCAT('%', 'soft', '%') OR ${name} LIKE CONCAT('%', 'soft', '%')` 
    }
  }
});

Answer 2

你就是这样做的

{
      or: [
        {
           "dimension": "Employee.company",
           "operator": "contains",
           "values": [
              "soft"
              ]
        },
        {
           "dimension": "Employee.name",
           "operator": "contains",
           "values": [
             "soft"
             ]
         }
       
      ];
    }
