Bigquery不等同

Question

想办法做一个＆＃34;而不是像＃34;与bigquery。我试过了

SELECT
  e.*
FROM
  T1 AS e
JOIN EACH T2 AS a
ON
  e.filename NOT LIKE CONCAT(a.filename, "%");

或

SELECT
  e.*
FROM
  T1 AS e
JOIN T2 AS a
ON
  REGEXP_MATCH(e.filename, CONCAT(a.filename, ".*" ))

给出相同的错误

ON clause must be AND of = comparisons of one field name from each table, with all field names prefixed with table name. .

有什么想法吗？

Answer 1

当您的ON条款违反以下要求时：

ON clause must be AND of = comparisons of one field name from each table, with all field names prefixed with table name. .

你可以使用

SELECT e.* FROM T1 AS e
CROSS JOIN  T2 AS a
WHERE <condition>

而不是

SELECT e.* FROM T1 AS e
JOIN  T2 AS a ON <condition>
