Oh, I just noticed, I forgot to post the error message of the second
try. This one, I can understand.
psql:test_02.sql:21: ERROR: statement returning results not allowed
CONTEXT: SQL statement "SELECT dblink_exec('pragma','select
WARN(P_MESSAGE := ''Raise dblink test'');')"

Hi all
I am trying to execute a function on a remote server using dblink to
test stuff.
My function is:
create or replace function /*LOGGER.*/WARN(in P_MESSAGE text)
returns void as
$warn$
begin
raise debug '%', P_MESSAGE;
raise log '%', P_MESSAGE;
raise info '%', P_MESSAGE;
raise notice '%', P_MESSAGE;
raise warning '%', P_MESSAGE;
end;
$warn$ language PLPGSQL;
I try to execute it with:
do language PLPGSQL
$anonymous$
begin
set session client_min_messages to log;
perform dblink_connect_u('pragma','dbname=thiemo password=XXX');
perform dblink_exec('pragma','perform WARN(P_MESSAGE := ''Raise
dblink test'');');
perform dblink_exec('pragma','commit;');
perform dblink_disconnect('pragma');
end;
$anonymous$
I get the error:
psql:test_02.sql:22: ERROR: syntax error at or near "perform"
CONTEXT: Error occurred on dblink connection named "pragma": could not
execute command.
SQL statement "SELECT dblink_exec('pragma','perform WARN(P_MESSAGE :=
''Raise dblink test'');')"
PL/pgSQL function inline_code_block line 12 at PERFORM
If I try to execute it with:
do language PLPGSQL
$anonymous$
begin
set session client_min_messages to log;
perform dblink_connect_u('pragma','dbname=thiemo password=XXX');
perform dblink_exec('pragma','select WARN(P_MESSAGE := ''Raise
dblink test'');');
perform dblink_exec('pragma','commit;');
perform dblink_disconnect('pragma');
end;
$anonymous$
Isn't it possible to execute funtions through dblink? Any hint is
appreciated.
Kind regards
Thiemo
