Unable to execute update statement

[EOtrade]

After connecting to PostgreSQL database, I can execute select statements, but any update statement produce error:

Error: This ResultSet is closed.

My configuration:

(use-package ejc-sql
  :config
  (ejc-set-rows-limit nil)
  (setq ejc-org-mode-show-results nil)
  (add-hook 'ejc-sql-minor-mode-hook
            (lambda ()
              (auto-complete-mode t)
              (ejc-ac-setup)))

  ;; Define connections
 (ejc-create-connection
   name
   :classpath "/home/rrudakov/.m2/repository/postgresql/postgresql/9.3-1102.jdbc41/postgresql-9.3-1102.jdbc41.jar"
   :subprotocol "postgresql"
   :subname (format "//%s:5432/%s" "hostname" "dbname")
   :user "username"
   :password "password"))

Could you provide a full stack trace, please (by enabling M-x toggle-debug-on-error)? Also, please show your leiningen & java versions (via lein version).

[EOtrade]

$ lein version
Leiningen 2.9.1 on Java 1.8.0_202 Java HotSpot(TM) 64-Bit Server VM

java -version
java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)

toggle-debug-on-error doesn't change anything. I got popup:

[kostafey]

Looks like you run queries from org-mode buffer. Ok, I can't reproduce exactly this issue, but could you please try the last version from master.

[rrudakov]

Looks like you run queries from org-mode

I tried both, from org-mode and from ejc-get-temp-edit-buffer. In master I still can reproduce the issue.

p.s: Wrote from another account

[kostafey]

Looks like, you query is considered as resulted with :result-set. Probably, we face here with select for update case or something like that. The actual code used to determine whether this SQL should have a result set or not is damn trivial: https://github.com/kostafey/ejc-sql/blob/master/src/ejc_sql/connect.clj#L121

Could you check it out? The actual debug process is simple. ejc-sql can be considered as common Clojure & Leningen & CIDER project. So, after run ejc-connect for any sql-mode or org-mode buffer, you can open connect.clj file, then type and eval (@db atom contains connection info of the last used database):

(in-ns 'ejc-sql.connect)
(eval-sql-core :db @db
               :sql "Actual SQL query")

[rrudakov]

Looks the same.

[kostafey]

What about direct evaluation:

(j/execute! @db (list "UPDATE profiles SET avatar='test' WHERE id=1"))

[kostafey]

1. Ok, first of all, please update ejc-sql from master. It uses org.clojure/java.jdbc from upstream.
2. Then please try the newest connection configuration parameters:

(ejc-create-connection
 "my-db-conn"
 :classpath "/home/rrudakov/.m2/repository/postgresql/postgresql/9.3-1102.jdbc41/postgresql-9.3-1102.jdbc41.jar"
 :dbtype "postgresql"
 :dbname "dbname"
 :host "hostname"
 :port "5432"
 :user "a_user"
 :password "secret")

3. Also, you can try the newest PostgreSQL JDBC driver (https://github.com/pgjdbc/pgjdbc):

mvn org.apache.maven.plugins:maven-dependency-plugin:get -Dartifact=org.postgresql:postgresql:42.2.5

then update ejc-create-connection:

(ejc-create-connection
...
 :classpath "/home/rrudakov/.m2/repository/postgresql/postgresql/42.2.5/postgresql-42.2.5.jar
...

4. If no luck with previous steps, it's worth to try run JDBC without clojure/java.jdbc wrapper at all, e.g.: https://docs.oracle.com/javase/tutorial/jdbc/basics/connecting.html I case of success with only this approach, please, open an issue in clojure/java.jdbc - Jira directly.

[rrudakov]

Seems like it works now. Thank you very much.

[kostafey]

You are welcome. Feel free to ask about ejc-sql usage and feature requests.

[AndreaCrotti]

Hi @kostafey , I'm getting the same error trying to execute INSERT/CREATE TABLE I tried also to run with the master version of ejc-sql (lein repl and connecting from emacs), but still get the same. And also j/execute! directly in the repl returns the same error.

Any suggestions about how to debug/fix it?

[kostafey]

@AndreaCrotti Could you please update ejc-sql to try with newest org.clojure/java.jdbc "0.7.10" from upstream. If no luck with it, could you provide the database type and JDBC driver you use for access.

[AndreaCrotti]

Actually I was already trying with 0.7.10, I just ran alein ancient upgrade before trying.

The db is a Postgres instance in a docker container

services:
  pg:
    image: postgres:10.4
    ports:

I can try with some other version too potentially if that could the issue.

[AndreaCrotti]

I also tried now with Postgres 12.1 to see if it made a difference but I get the same result..

[kostafey]

@AndreaCrotti, could you provide your database configuration created by ejc-create-connection with mangled username and password, please?

[meditans]

I have the same problem - namely, if I try to do INSERT or CREATE TABLE I get:

Error: This ResultSet is closed.

I could provide the appropriate versions, or better errors, if I knew how, @kostafey. An interesting tidbit I noticed though: when I connect via ejc-connect-interactive I get this error:
