Thread: query total time im milliseconds
Dear all ,
could any one help me?
when i use pgadmin to exceute a query it shows the total time for query ..
such as
(select * form table_name.........)query total time is for example 100 ms
i want to know the command that can retetive the query total time in millisecond
if i connect with postgresql from java using JDBC
i need the query total time necessary to use it in my project
i don't want run explian,explain gives estimated i want real total time for the query
thank's

Run your query. Subtract the recorded value from the current value of System.currentTimeMillis() or System.nanoTime() to get the execution time including how long the query took to transfer data from the server to your client. I'm not aware of a way to find out how long the query took to execute on the server - excluding data transfer to the client - without using EXPLAIN ANALYZE. -- Craig Ringer POST Newspapers 276 Onslow Rd, Shenton Park Ph: 08 9381 3088 Fax: 08 9388 2258 ABN: 50 008 917 717 http://www.postnewspapers.com.au/
