Multiline SQL commands are not supported?  Well that sucks, because 
only

BUFSIZ chars are read from each line.  In my platform that's 8192, but
maybe in Simeó's case it's shorter .. or maybe his query really is
longer than 8192 bytes.

This smells like a pgbench bug to me.

Álvaro, you hit the nail on the head!

I have seen that in stdio.h BUFSIZ is defined like 1024 in freeBSD 9.0, 
probably for this reason I can't test this query (1657 characters), but 
I'm able to test shorter queries.


Finally I have done a plsql procedure to call the query from pgbench. 
Meanwhile I will try to figure out if I can increase this variable 
without affect the system.


Thanks to all

[GENERAL] pgbench

2013-10-03 Thread Simeó Reig

 Hello

 I was doing a performance test with pgbench with a pretty long queries 
and I have the next error:


 $ pgbench -n -c1 -T 3 -f veins_pgbench.sql pdn
 Client 0 aborted in state 0: ERROR:  syntax error at end of input
 LINE 1: ...(abc.persones.provincia = abc.poblacions.cod_provinc
 ^
 transaction type: Custom query
 scaling factor: 1
 query mode: simple
 number of clients: 1
 number of threads: 1
 duration: 3 s
 number of transactions actually processed: 0
 tps = 0.00 (including connections establishing)
 tps = 0.00 (excluding connections establishing)

 I believe pgbench has a very low limit with the queries you can put 
inside a file with the 't' option.

 Am I right? How can avoid it ?

 My best regards

Well first you say 't' option but show 'T' option, they are different.

Second the error is reporting a syntax error in your script, so I
would look there first.


Yes, I did I mistake. I would say 'f' option (file option) not 't' 
option, sorry . But no, there is no mistake with the script, I can do:


# psql -d pdn  veins_pgbench.sql

and it works perfectly

thanks Adrian, I'm almost sure that the problem is the query is too 
long for pgbench (1600 characters)

You have not shown the query, but could you be running into the belwo:

http://www.postgresql.org/docs/9.3/interactive/pgbench.html

The format of a script file is one SQL command per line; multiline
SQL commands are not supported. Empty lines and lines beginning with
-- are ignored. Script file lines can also be meta commands, which
are interpreted by pgbench itself, as described below.




I did it, and I read it all ... I'm use to work with postgresql and 
freeBSD world since too years ago ;-)


Thanks again Adrian

Obviously pgbench has issues with the syntax in the file. Without the
contents of the file I am just doing some educated guessing. To get to
a solution you will need to show your custom file.



Yes you are right, It has an issue with the syntax, because it only 
reads a portion of the query, and obviously it's not correct if you do 
it.


Unfortunately I can't put the sql here, but I repeat: I could do:

psql -d databasename  scrip_file.sql

and it works perfectly, and It is a one line query.

I did it with many queries since today, but I think this is too long

Many many thanks for your interest Adrian
