Java.SQL错误：准备好的语句未处于批处理模式

我将Java与后端HSQL一起使用。我事先准备好的声明在早些时候运作良好。最近，我创建了department和items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/更新都会失败，错误如下 “语句未处于批处理模式”

表结构如下所示：

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。下面是我试图在Items表中插入数据的代码，部分代码如下所示。我希望这是有意义的，我已经更改了名称和列，因为我不能共享实际的代码

 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) ;

您需要使用而不是

executeUpdate

还要确保您的代码调用

addBatch

至少一个。请参见使用

 int affectedRows = statement.executeBatch();

executeBatch（）

的返回类型为int[]

---

请尝试更改此项。

很抱歉，我写了一篇文章，错误地执行了更新，在我的代码中，它使用的是executeBatch。在问题中也已更正。您能发布所获得错误的完整堆栈跟踪吗？添加到问题中，因为在另一条评论中提到的@Maverick很可能从未调用过

addBatch

。谢谢添加链接。我无法复制粘贴代码，所以在那里犯了一个错误。如果您看到任何语法错误，请忽略。代码编译得很好。我面临运行时错误。你能检查批处理是否为空吗？当批次为空时，也会导致此异常，即批次中没有项目。检查：

查看（WersMapping WersMapping:wersMapList）{

谢谢@Maverick，我注意到我的本地存在一些数据问题，因此批本身是空的。
