Can we show a insert complex SQL in a sequence diagram?

From the main source the SQL is inserting the data to final table, in between it creates many other tables from which data finally flows to the main table. I have created a sequence dropping the .SQL name in box followed with this created table sections. But me question is for every sequence we have a return dotted line. So in this scenario what can we return when it is trying to get the source data to local db table?

Hi there and welcome to the forum!

I’m not quite sure: are you running INSERTs with Redash?

Redash is built only for running SELECT statements. It has no tooling whatsoever to display non-tabular results from the database (with the exception of error messages).
