DBUtils3 wrapper

A Clojure library designed to use DBUtil3.

Usage

create DBConnectionUtil

(def dbconn (create-dbconnectionutil connection))

precompile SQL

(db-prepare dbconn "insert into table values (:id, :count, :text)")

or

(db-prepare dbconn "select  * from table where id = ?")
(db-prepare dbconn "insert into table values (?, ?, ?)")

execute query

(db-query dbconn {"id" 3})

or

(db-query dbconn [3])

execute update

(db-update dbconn {"id" 3, "count" 4, "text" "data"})

or

(db-update dbconn [3 4 "data"])

transaction managment

(db-commit dbconn)
(db-rollback dbconn)

example

(let [dbconn (create-dbconnectionutil conn)]
  (-> dbconn
      (prepare "select * from test where id = ?")
      (query [1])))
; --> [{"ID" "0", "NAME" "test00"}]

(let [dbconn (create-dbconnectionutil conn)]
  (-> dbconn
      (prepare "insert into test values (?, ?)")
      (update [1, "test01"])))
; --> 1

(let [dbconn (create-dbconnectionutil conn)]
  (-> dbconnn
      (prepare "insert into test values (?, ?)")
      ((fn [conn]
         (for [i (range 2 10)]
           (db-update conn [i (format "test%02d" i)]))))))
; --> (1 1 1 1 1 1 1 1 1 1 1)
