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.
Bye,
Chris.
