替换 clickhouse 中的 row_number()

Question

clickhouse数据库不支持Row_number()，寻找替代函数。

SELECT company_name AS company,
       DOMAIN,
       city_name AS city,
       state_province_code AS state,
       country_code AS country,
       location_revenue AS revenueRange,
       location_TI_industry AS industry,
       location_employeecount_range AS employeeSize,
       topic,
       location_duns AS duns,
       rank AS intensityRank,
       dnb_status_code AS locationStatus,
       rank_delta AS intensityRankDelta,
       company_id,
       ROW_NUMBER() OVER (PARTITION BY DOMAIN) AS rowNumberFROM company_intent c
 WHERE c.rank > 0
   AND c.rank <= 10
   AND c.signal_count > 0
   AND c.topic IN ('Cloud Computing')
   AND c.country_code = 'US'
   AND c.rank IN (7, 8, 9, 10)
 GROUP BY c.location_duns,
          company_name,
          DOMAIN,
          city_name,
          state_province_code,
          country_code,
          location_revenue,
          location_TI_industry,
          location_employeecount_range,
          topic,
          rank,
          dnb_status_code,
          rank_delta,
          company_id
 ORDER BY intensityRank DESC
 LIMIT 15 SELECT COUNT (DISTINCT c.company_id) AS COUNT
  FROM company_intent c
 WHERE c.rank > 0
   AND c.rank <= 10
   AND c.signal_count > 0
   AND c.topic IN ('Cloud Computing')
   AND c.country_code = 'US'
   AND c.rank IN (7, 8, 9, 10)

执行上述查询时出现以下错误。

预期之一：SETTINGS、FORMAT、WITH、HAVING、LIMIT、FROM、PREWHERE、token、UNION ALL、逗号、WHERE、ORDER BY、INTO OUTFILE、GROUP BY

Answer 1

ClickHouse 目前不支持窗口函数。您可能会感兴趣一个rowNumberInAllBlocks函数。

Answer 2

SELECT
    *,
    rowNumberInAllBlocks()
FROM
    (
        -- YOUR SELECT HERE
    )

https://clickhouse-docs.readthedocs.io/en/latest/functions/other_functions.html说：

rowNumberInAllBlocks()返回此函数处理的所有块内的增量行号。
