Adding results up
Hi There

Just created a .sql script and executes fine, it comes back with two lines of results, I was wondering is there a way of adding up the two results to get a round number. I tired wc -l but that didn't work.

Many Thanks for your help

Code:
psql -t -f /opt/ca/SAP_Tooling/sql/self_monitoring/check_number_of_open_connections_database.sql

The result is:
Quote:
34 | idle
1 | active
Is there any way of adding those two numbers to get a whole round number of users as in 35.

Can you post the content of /opt/ca/SAP_Tooling/sql/self_monitoring/check_number_of_open_connections_database.sql If we can adjust that, then for sure you can get a total. If not, then if we can decipher it then we can write another bit to count them all.

Hi Robin

Thanks for the reply, yes I can.
Code:
select count(*), state from pg_stat_activity group by state;
\q

Cheers
Alex

You have two main choices:-

Adding another line into your SQL, you could try
Code:
select count(*), state from pg_stat_activity group by state;
select count(*) from pg_stat_activity;
\q

If you need to get the value into the script, you could have a follow up script with just the one line like this
Code:
select count(*) from pg_stat_activity;

then call it as a subshell so the output ends up in a variable, e.g.
Code:
total_recs=$(psql ............)



I hope that this helps,
Robin

results survey

Hi guys! I was wondering what the outcome was of your survey of a few months ago? One of the questions was if people were willing to pay for additional services like an own account, like username@unix.com with mail box, etc. Sorry if I missed the results if you had already posted them.
