Clojure / postgresql：当db中有错误时，如何看到异常？ [英] Clojure/postgresql: How do I see the exception when an error is in the db?

问题描述

当使用clojure和postgresql时，每当我发出的语句以某种方式格式化或者被数据库本身拒绝时，我得到类似以下错误：

When using clojure with postgresql, whenever a statement I issue is malformed in some way or otherwise rejected by the db itself I get something like the following error:

java.sql.BatchUpdateException: 
  Batch entry 0 drop schema public cascade was aborted.  
  Call getNextException to see the cause.

如何调用getNextException以便我可以看到我做错了什么？我从哪里调用它？

How can I call getNextException so that I can see what I did wrong? Where do I call it from?

推荐答案

查看此关于clojure / jdbc的链接，显示如何使用Clojure / JDBC删除表。

See this link on clojure/jdbc showing how to drop a table with Clojure/JDBC.

使用try catch块来处理错误。

It also shows you how to handle errors with a try catch block.

在try catch块中，您可以编写类似的内容：

From within that try catch block, you can write something similar to:

(.printStackTrace (.getCause e))
