Bigquery nicht in gleichwertigem

Question

Suchen Sie einen Weg, um ein "nicht in wie" mit bigquery zu tun. Ich habe versucht,

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

oder

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

Geben Sie den gleichen Fehler

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

Jede Idee?

Answer 1

Wenn Ihre ON-Klausel verstößt unter Voraussetzung: CROSS JOIN teuer ist:

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

Sie

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

statt

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