sql - _TABLE_SUFFIX 丢失？

Question

我试图在 BigQuery 中使用这段代码，显然是从 GA 中获取数据，但 _TABLE_SUFFIX 似乎有问题。错误显示“错误:无法识别的名称:_TABLE_SUFFIX at [12:3]”您能帮忙找出原因吗？

SELECT
fullVisitorId,
visitId,
visitNumber,
hits.hitNumber AS hitNumber,
hits.page.pagePath AS pagePath
FROM
`110042578.ga_sessions_intraday_20190228`,
UNNEST(hits) as hits
WHERE
_TABLE_SUFFIX = '20190228'
AND
hits.type="PAGE"
ORDER BY
fullVisitorId,
visitId,
visitNumber,
hitNumber

Answer 1

如果表引用中没有通配符 *，则没有字段 _table_suffix。尝试一下

SELECT
  fullVisitorId,
  visitId,
  visitNumber,
  hits.hitNumber AS hitNumber,
  hits.page.pagePath AS pagePath
FROM
  `110042578.ga_sessions_intraday_*`,
  UNNEST(hits) as hits
WHERE
  _TABLE_SUFFIX = '20190228'
  AND
  hits.type="PAGE"
ORDER BY
  fullVisitorId,
  visitId,
  visitNumber,
  hitNumber
