I've been developing for MS SQL around four years. I'm starting out with some work in Postgresql next week, and I'd like to know if there's any equivalent way to do something like this (from my word press)
My question is mainly about creating comma delimited column names as variables and executing dynamic SQL with them. I've spent some time trying to find an answer and I seem to keep running into the same few stack questions.
Any advice is appreciated. I think I'm going to end up needing dynamic queries like what I've written for similar tasks moving data from files to staging tables and then to a larger set of data warehouse tables and setting up either views (perhaps materialized?) or more tables for reporting.
It can look some like
CREATE OR REPLACE FUNCTION sample_insert_noflag(table_from text, table_to text, query_filter text)
