Hi list,

It is possible to retrieve the time of a SQL statement leads to
execute ? I would like to put in my application how much time each
operation leads to finish.

Any suggestion ?

TIP 5: don't forget to increase your free space map settings

I preffer that the database give me this information. I don't know if
it is possible becouse if we retrieve many rows and if we want to put
this result in a new column the same time will be replicated many
times and consuming more processing.

Any other suggestion ?

Assuming you're using stored procedures...
Start procedure with logging current time, name of procedure,...
Perform whatever must be performed
End procedure with logging current time, name of procedure,...
Query logging table to get time spent

Alternative, still assuming you're using stored procedures...
Start procedure with noting current time, name of procedure,...
Perform whatever must be performed
End procedure with logging current time - start time, name of procedure,...
Query logging table to get time spent

EXPLAIN ANALYZE is only for tuning purposes.
Read the manual (http://www.postgresql.org/docs/8.1/i...-explain..html) to get more insight

EXPLAIN ANALYZE Is perfect but i have no idea of how to use it. My
resultset is retrieving my rows.

Another question that cames with the Analyze. PgAdmin return the time
to retrieve the data or all time to fill the grid on the "SQL Editor".

EXPLAIN ANALYZE does give the query execution time at the end of its output.
