Question

我在JBehave非Maven框架中工作，我正在运行一个插入语句，该语句位于一个文本文件中，我将其作为qry传递给我的方法。 insert语句是：

Insert into croutreach.ACME_OUTREACH_EMT_STG 
(SEQ,EID,EVENT_TYPE_HINT,LOADER_TYPE,CLIENT_ID_LIST,ACCT_NUM_LIST,PROCS_DT)
values (49,<EID>,'new','CI',null,null,'02-SEP-13 06.55.41.952000000 PM')

以下代码正在执行并打印以下声明

执行以运行插入查询

但在此之后它没有进入下一步，这就是为什么连接没有关闭。它被卡住preparedstatement.executeupdate()。

private Connection dbConnection = null;
public boolean runInsertQuery(String qry) {
int result;
System.out.println("Preparing to run insert query");
try {
    PreparedStatement preparedStatement =dbConnection.prepareStatement(qry);
    System.out.println("Execuing to run insert query");
    result = preparedStatement.executeUpdate();
    System.out.println("Completed to run insert query");
    return result == 1;
    } catch (SQLException e) {
        LOG.fatal("Error in insertion into table  :", e);
        return false;
    } finally {
        this.disconnectDb();
    }
}

我的输出如下： -

之前我保持我的SQL开发人员窗口打开，在关闭后再次尝试并再次运行相同的脚本时，它显示致命错误asORA-00001：违反了唯一约束。

我面临三个不同的问题：

当SQL Developer处于打开状态时，运行脚本会卡在插入位置。

虽然卡住了但我关闭了SQL Developer窗口会话，之后输出如下：

2015-11-03 05:01:35,061 INFO main- DB Connection successful
Insert into croutreach.ACME_OUTREACH_EMT_STG (SEQ,EID,EVENT_TYPE_HINT,LOADER_TYPE,CLIENT_ID_LIST,ACCT_NUM_LIST,PROCS_DT) values (49,'02123456789','new','CI',null,null,'02-SEP-13 06.55.41.952000000 PM')
Preparing to run insert query
Executing to run insert query
Completed to run insert query
2015-11-03 05:02:11,128 INFO main- DB Disconnected!!
Insert complete

关闭SQL Developer窗口后，再次运行脚本但出现致命错误，如下所示：

2015-11-03 05:13:08,177 INFO main- DB Connection successful
Insert into croutreach.ACME_OUTREACH_EMT_STG (SEQ,EID,EVENT_TYPE_HINT,LOADER_TYPE,CLIENT_ID_LIST,ACCT_NUM_LIST,PROCS_DT) values (49,'02123456789','new','CI',null,null,'02-SEP-13 06.55.41.952000000 PM')

您只是看到一个会话阻止了另一个会话。当您在SQL Developer中执行插入并使会话保持运行而不提交或回滚时，您将锁定新插入的行和（某种待处理的）索引条目。

如果您运行程序并再次执行相同的插入，则会在另一个会话中执行。它无法看到您通过SQL Developer插入的数据，但它可以看到锁定，并等待清除该锁定。虽然它被阻止了它只是坐在那里等待，你正在解释它被卡住了。

如果您回滚SQL Developer插件，则会清除锁定，然后您的程序被阻止插入，然后成功继续。插入新记录，并根据您的代码下一步做什么或连接的自动提交设置提交或回滚。

它看起来像是提交，因为再次运行会尝试重复插入，现在它确实会看到现有的已提交数据 - 因此会出现ORA-00001错误，因为您正在尝试创建第二个条目相同的主键值。如果你提交了SQL Developer会话而不是回滚，你会看到同样的事情。

如果您想再次运行程序，则需要在再次尝试插入之前删除该行（并提交更改！）。

preparedStatement.executeUpdate（）不插入值
