Clojure wrapper for Apache DBCP to create JDBC connections pools
Hello!
I'm getting the following error when trying to use make-datasource
:
db-spec org.apache.commons.dbcp.BasicDataSource@56a9509d is missing a required parameter
Here is some sample code to reproduce:
#!/bin/bash lein-exec
(use '[leiningen.exec :only (deps)])
(deps '[[org.clojure/java.jdbc "0.2.3"]
[postgresql/postgresql "8.4-702.jdbc4"]
[clj-http "0.5.6"]
[clj-dbcp "0.8.0"]])
(require '[clj-dbcp.core :as dbcp])
(require '[clj-http.client :as client])
(require '[clojure.java.jdbc :as sql])
(defn query
[addr #^String query]
(sql/with-connection addr
(sql/transaction
(sql/with-query-results results
[{:fetch-size 100
:concurrency :read-only
:result-type :forward-only}
query]
(into [] results)))))
(def db-config (dbcp/make-datasource (dbcp/parse-url "postgresql://[email protected]/mydb")))
(println (take 10 (query db-config "SELECT * FROM forum_posts LIMIT 10")))
Note that if I do the following:
...
(println (take 10 (query "postgresql://[email protected]/mydb") "SELECT * FROM table LIMIT 10")))
Then it works fine. What am I missing?
Hi, is it possible to close ALL connections to the db?
I tried closing datasource, connection from data source, nothing help me.
