10/23/2023, 9:29 PMHi! I'm trying to set use an experiment with Amplitude and bigquery. However I'm running into issues when trying to query the results. Any way I can alter the SQL for the whole query? I'd like to try
SUM(COALESCE(value,"0")) AS valuef

Hi, you can’t edit it as a whole, but you can edit all parts of it

The main exposure query is on the data source page, under assignment queries

Most of the time If there are errors it’s in the assignment query

In this case, it looks like the metric value you are selecting is a string when it needs to be a number (int or float)

If you want to continue using strings and do something like COUNT DISTINCT, you can override the aggregation when setting up the metric:
