Home >PostgreSQL > postgres tip: how re-execute a query every n second

Stampa  Stampa


The PostgreSQL command \watch n it is very handy when you want to update query results every n seconds, and it is very easy to use. For example, If I want to keep an eye on the total of rows on my transaction table every 5 seconds:
-- I just run once my query
finance=# select count(1) from finance.transaction_log;
 count 
-------
 24875
(1 row)
--  then issuing the watch command the query will be executed every 5 seconds until I stop it(CRTL+z)
switch=#  \watch 5
Watch every 5s Tue May 26 17:42:00 2015 count ------- 24875 (1 row) Watch every 5s Tue May 26 17:42:05 2015 count ------- 24890 (1 row) Watch every 5s Tue May 26 17:42:10 2015 count ------- 24897 (1 row) (...)
