My reference is Transpose rows into columns in BigQuery (Pivot implementation)
I tried to implement the recommendation in standard big query by replacing group_concat_unquoted by string_agg but I don't succeed in using the correct syntax and structure.
WITH
input AS (
SELECT
user_pseudo_id AS user_id,
event_timestamp,
p.key AS key,
p.value.string_value AS value
FROM
`myproject.analytics_xxxx.events_*`,
UNNEST(event_params) AS p
WHERE
AND event_name = 'event_type_to_pivot' )
SELECT
'select user_id, ' + STRING_AGG(
'MAX(IF(key = "'+key+'", value, NULL)) as ['+key+']'
) + 'FROM input group by user_id order by user_id'
FROM (
SELECT
key
FROM
input
GROUP BY
key
ORDER BY
key )
I get consistently an error :
No matching signature for operator + for argument types: STRING, STRING. Supported signatures: INT64 + INT64; FLOAT64 + FLOAT64; NUMERIC + NUMERIC at [19:3] for line:
STRING_AGG(
'MAX(IF(key = "'+key+'", value, NULL)) as ['+key+']'
)
After a lot of tries, I still don't get how to use properly string_agg to transpose rows into columns.
Thanks for your guidance,

In #standardSQL use CONCAT() instead of + to compose strings:
'MAX(IF(key = "'+key+'", value, NULL)) as ['+key+']'
->
CONCAT('MAX(IF(key = "',key,'", value, NULL)) as [',key,']')
