Javascript 当数据为json时，如何使用knex比较或过滤数据

当数据是json时，如何使用where过滤数据

我的桌子

还有我的密码

knex('companies')
        .join('company_integrations', 'companies.id', '=', 'company_integrations.company_id')
        .select('companies.id as id', 'companies.uuid as uuid', 'company_integrations.method as method', 'company_integrations.configurations as configurations').limit(5).then(function(resp) {
            logger.capture('info', resp)
        })

我的查询输出

{
  "level": "info",
  "timestamps": "17:44:39",
  "message": [
    {
      "id": 1475,
      "uuid": "92db9710-5276-11e8-a91b-2f2aa8f44baa",
      "method": "open-api",
      "configurations": "{\"company_code\":\"034\",\"issue_point_rate\":\"10.00\",\"issue_fee_rate\":\"5.00\",\"redeem_fee_rate\":\"20.00\"}"
    },
    {
      "id": 1086,
      "uuid": "7cfcbd00-333e-11e8-8e97-ad56f124a756",
      "method": "ponta",
      "configurations": "{\"company_code\":\"034\",\"issue_point_rate\":\"10.00\",\"issue_fee_rate\":\"5.00\",\"redeem_fee_rate\":\"20.00\"}"
    },
    {
      "id": 1565,
      "uuid": "5795c950-5cff-11e8-b813-1782fbf3df1c",
      "method": "ponta",
      "configurations": "{\"company_code\":\"034\",\"issue_point_rate\":\"10.00\",\"issue_fee_rate\":\"5.00\",\"redeem_fee_rate\":\"20.00\",\"merchant_id\":\"1abc\",\"active\":0}"
    },
    {
      "id": 1565,
      "uuid": "5795c950-5cff-11e8-b813-1782fbf3df1c",
      "method": "e-cash",
      "configurations": "{\"active\":true}"
    },
    {
      "id": 2015,
      "uuid": "4b615d90-7dc3-11e8-8d59-012e7c4e4fb1",
      "method": "yap!",
      "configurations": "{\"company_code\":\"034\",\"issue_point_rate\":\"10.00\",\"issue_fee_rate\":\"5.00\",\"redeem_fee_rate\":\"20.00\"}"
    }
  ]
}

我想使用whereRaw在条件类似时仅检查/过滤数据

configurations->active=true

或价值

configurations->company\u code=something
