Yes. You can use commands and variables psql.

\set TempDirectory /home/... -- in file global.sql
\i global.sql

SELECT somefce(:TempDirectory)

sorry, i badly explain my second problem (and it make me think about an other question :) )
what i really want to say is :
i would like to declare a global variable :
    DEFINE pool = 10
and use it into a function
    @createMDNS.sql &pool
and my file createMDNS.sql is
    create or replace package body MDXML_EXPORT
     as
       pool varchar2(150) := '&1';
        procedure toto(.......
    .....
    .....
    /
that what i wanted to explain

and my new question is :) :
i wrote a first file :
    \set databaseName 'base1'
    \set createMDXML '/home/toto/MDXML/execCreateMDXML.sql'
    \i :createMDXML
and in my second file, i need the name af the database but if i wrote this :
    SET search_path TO :databaseName;
it doesn't work....

regards

There is one big difference. PostgreSQL don't know global variables. There
is only local variables in stored procedures or local variables of sql
monitor ~ psql. You cannot directly read psql's variables.

I am sorry. I can't help.

create schema fx;
create table fx.foo(i integer);
select * from foo;
ERROR:  relation "foo" does not exist
\set sp fx
set search_path to :sp
intra=# \set sp 'fx'
intra=# set search_path to :sp;
SET
Time: 9,349 ms
intra=# select * from foo;
 i
---
(0 rows)

look to /home/toto/MDXML/execCreateMDXML.sql sqlscript. Works really well?

Pavel

the search_path works well
