I have a database (PostgreSQL) with a lot of records and some unique date for each record. Now I also a have a dictionary with record id as key, and some date as value.
I would like to query all the records from the database, where their date is smaller than the date I have in the dictionary.
I wonder what is the best way to write this query.
- Query one record by one.
- Query in batches by concatenation of OR conditions.
- Group the dictionary values by unique key and query using “IN” operator (if all the dates are unique it’s the same as the first option).
I’m open for any other suggestions… Thanks!
