如何在BigQuery中正确使用字符串聚合子句？已编辑

Question

我无法使STRING_AGG（）子句起作用。我收到错误：  “ SELECT列表表达式引用的consignment_items.receiver_id既不在[3：1]也不进行分组或聚集，”

SELECT
table1.field1 AS alias1,
table1.field2,
table1.field3,
table2.field4,
table2.field5 AS alias2,
STRING_AGG(table3.field9, '|') AS alias3
FROM database.table1 table1
JOIN database.table3 roles ON table1.field1 = table3.field6
JOIN database.table2 ON table1.field2 = table2.field7

Answer 1

GROUP BY
