Dear folks, I have a table with thousands of rows ( currently 15 thousand but will grow very fast). I need to return from the query rows which are random and non-repeating. I know there is random() function, but would like to know from postgresql practitioners before embarking that path. Please let me know what is best way to handle this type of queries. regards Kiran
Hi, if you're using Postgres >= 9.5 what you are looking for is TABLESAMPLE. Syntax is here: https://www.postgresql.org/docs/9.5/static/sql-select.html Google tablesample+postgres to get some examples on how to use it.
