Java.SQL 错误：Prepared Statement 不在批处理模式下

【中文标题】Java.SQL 错误：Prepared Statement 不在批处理模式下【英文标题】：Java.SQL Error: Prepared Statement not in batch mode 【发布时间】：2015-08-17 09:56:55 【问题描述】：我正在使用 Java 和后端 HSQL。我准备好的声明早些时候工作正常。最近，我创建了部门和项目表之间的依赖关系，并将 dep_seq_id 列从自动生成的 seq_id 变成了一个简单的列（我们现在正在通过 java 代码更新 id）。在这些更改之后，所有依赖表的创建/更新都失败并出现错误，例如 “语句不在批处理模式下”。
表格结构如下：
CREATE TABLE DEPARTMENT
(
DEP_SEQ_ID INTEGER NOT NULL,
DEPT_STATE VARCHAR(6) NOT NULL,
NAME VARCHAR(20) NOT NULL,
YEAR VARCHAR(4),
CREATE_DATE DATE,
LINK VARCHAR(255),
PRIMARY KEY(SEQ_ID,DEPT_STATE)
);
CREATE TABLE ITEMS
(
ITEM_ID INTEGER NOT NULL,
ITEM_STATE VARCHAR(6) NOT NULL,
NAME VARCHAR(20),
ITEM_CODE VARCHAR(10),
DEP_SEQ_ID INTEGER,
DEPT_STATE VARCHAR(6),
FOREIGN KEY(DEP_SEQ_ID,DEPT_STATE) REFERENCES DEPARTMENT(SEQ_ID, DEPT_STATE) ON
DELETE CASCADE ON
UPDATE CASCADE
);
我不明白我在这里做错了什么。以下是我尝试在 Items 表中插入数据的代码，部分代码如下所示。我希望这是有道理的，我已经更改了名称和列，因为我无法分享实际代码。
PreparedStatement statement = null;
ResultSet generatedKeys = null;
Long mappingId = null;
try
statement = m_connection.prepareStatement("insert into ITEMS (ITEM_ID, ITEM_STATE, NAME, ITEM_CODE, DEP_SEQ_ID, DEPT_STATE) values(?,?,?,?,?,?)");
for(WersMapping wersMapping : wersMapList)
statement.setLong(1, item.getItemId());
statement.setInt(2, item.getState());
statement.setString(3, item.getName());
statement.setString(4, item.getItemCode());
statement.setInt(5, item.getDeptId());
statement.setString(6, item.getDeptState());
statement.addBatch();
int[] nArray = statement.executeBatch();
int totalInserts = 0;
if(nArray != null)
for(int n:nArray)
totalInserts = totalInserts + n;
LOGGER.log(Level.INFO, "Successfully created "+totalInserts + " Mapping instances");
return new Long(totalInserts) ;

【问题讨论】：
【参考方案1】：您需要使用executeBatch 而不是executeUpdate。
还要确保您的代码至少调用了一个addBatch。见http://sourceforge.net/p/hsqldb/discussion/73673/thread/926b13f4/
【讨论】：
对不起，我写错了，executeUpdate，在我的代码中，它使用了executeBatch。问题中也已更正。 你能发布你得到的错误的完整堆栈跟踪吗？ 添加到问题中 正如@Maverick 在另一条评论中提到的那样，addBatch 很可能从未被调用过。见sourceforge.net/p/hsqldb/discussion/73673/thread/926b13f4
感谢您添加链接。【参考方案2】：
使用
int affectedRows = statement.executeBatch();
executeBatch()的返回类型是int[]。
尝试更改此设置。
【讨论】：
我无法复制粘贴代码，所以这里出错了。如果您看到任何语法错误，请忽略。代码编译正常。我面临运行时错误。 你能检查批次是否为空吗？当批次为空时也会导致此异常，即批次中没有项目。检查：for(WersMapping wersMapping : wersMapList)
感谢@Maverick，我注意到我的本地存在一些数据问题，因此批处理本身是空的。以上是关于Java.SQL 错误：Prepared Statement 不在批处理模式下的主要内容，如果未能解决你的问题，请参考以下文章
