In addition to the error that I mentioned in my earlier post ("No results"
exception on executeQuery() - see below), I get the following when I try to
commit a connection:
java.sql.SQLException: ERROR: SET TRANSACTION ISOLATION LEVEL must be
called before any query

Subject: [JDBC] "No results" exception on executeQuery()
Hello. I just update my driver to the latest version (7.1-1.3). I am
seeing MANY of the following exception:
No results were returned by the query.
at org.postgresql.jdbc2.Statement.executeQuery(Statement.java:63)
at
com.commnav.sbh.framework.persist.JDBCEngine.executeQuery(JDBCEngine.java:22
1)
at
com.commnav.sbh.framework.persist.PersistenceObject.query(PersistenceObject.
java:1046)
...
I checked the history of this listserv and found some related but not quite
relevant stuff (part of the thread is below - it talks about using
executeUpdate for update/insert/delete)...
I am sometimes getting this exception even when there should be results
returned...
I appreciate any help.
chris

Subject: [JDBC] "No results" exception on insert
Hello,
I have some code which is essentially doing the following:
Statement stmt;
ResultSet rs = stmt.executeQuery("insert into users values ( 'joe', 'blow'
)");
The values are inserted into the table correctly. I verified this using
psql:
"select * from users".
The problem is that the executeQuery throws an Exception. The message
is "No results were returned by the query":
No results were returned by the query.
at org.postgresql.jdbc2.Statement.executeQuery(Statement.java,
Compiled
Code)
My driver is "org.postgresql.Driver" from the jar file jdbc7.0-1.2.jar. I
think
the port version is 7.1 The platform is FreeBSD 4.2-RELEASE.
I am using linux jdk 1.2.2.
Can anyone give me any ideas?
Thanks,
Brian
