How to skip errors when using json_extract_path_text in Redshift?

Question

I have the following query:

SELECT 'curl -s http://www.mde.operator.com/MRE/api?profile=CANCEL_AUTH&mode=assync-oneway&Auth='||json_extract_path_text(external_reference_id,'transactionIdAuth') + '&NUM=' + phone  FROM dbo.cancelled WHERE id like '%Auth%';

It will bring more than 60 thousands results, but the json is broken and I cannot manage to delete the broken lines.

Is there any way to skip the rows which shows any kind of errors?

Note: It isn't null rows.

I've already try:

json_extract_path_text(regexp_replace(event_properties,'\\\\.',''),'someValue')

Answer 1

You can make them null rows though, by setting the null_if_invalid argument of the json_extract_path_text function to true .
