如何使用clojure在JDBC中禁用自动提交 [英] How to disable autocommit in JDBC using clojure

问题描述

我想使用Clojure的JDBC接口来更新Hive数据库。特别是，我想添加分区。代码如下：

I want to use Clojure's JDBC interface to update an Hive database. In particular, I want to add partitions. The code would be like the following:

(jdbc/db-do-commands hive-db ["ALTER TABLE foo ADD PARTITION (year=2015, month=10, day=1, hour=1) LOCATION '/bar'"])

$ b b

但是，我收到一个错误：

However, I'm getting an error:

java.sql.SQLException: enabling autocommit is not supported
 at org.apache.hive.jdbc.HiveConnection.setAutoCommit (HiveConnection.java:1071)
    clojure.java.jdbc$db_transaction_STAR_.doInvoke (jdbc.clj:605)
    clojure.lang.RestFn.invoke (RestFn.java:425)
    ...

，在Hive的JDBC驱动程序中启用自动提交功能后，几个未解决问题。因此，我想禁用自动提交。如何在 clojure.java.jdbc ？

As I'm aware, enabling autocommit in Hive's JDBC driver has several unresolved issues presently. Thus I want to disable autocommit. How is this done in clojure.java.jdbc?

推荐答案

类似以下的东西将是有帮助的：

Perhaps something like the following would be of assistance:

(let [con (db-find-connection db)]
   (.setAutoCommit con false))

运气最好。
