Dear Robert
The server is external and I'm not in able to upgrade the
PostgreSQL-server. Because of the age I was afraid for choosing a "new"
jdbc-driver. But I followed your suggestion to replace the jdbc4-driver
with last edition and it worked nice with the new driver
postgresql-42.2.1.jar.
Thanks a lot, Robert.

Have a nice day.

Regards
-Gunnar;)

Dear Sirs,
As quite new in this discussiongroup I have red a lot about
statement_timeout, but I can't find any answer on the following
problem:

My JavaEE-code responds the fpllowing Error message:

Method
org.postgresql.jdbc4.Jdbc4PreparedStatement.setQueryTimeout(int) is
not yet implemented

Javacode:
PreparedStatement AA = null;
..
..
AA.setQueryTimeout( 5000 ); // This sentence generates the fault-
message

PostgreSQL version: 9.1.24
( Only READ-access )

JDBC4 version: postgresql-9.0-801.jdbc4.jar

My application reads contiously a SELECT-sentence every 10 seconds,
and needs to be aborted if it not returns in during of 5 seconds.

Is the functiion setQueryTimeout(INT) not yet implemented in JDBC4,
or is it the PostgreSQK-server which is not yet implemented?

How shall I implement statement_timeout in my JavaEE code, when I
only has Read-access to PostgreSQL, to avoid this ErrorMessage?

-Gunnar

There was a fix to this in Version 9.4-1205 of the driver.
Also, your version of PostgreSql is ancient.

I think an upgrade would be worthwhile.

HTH,
Robert
