ORA-00604: 递归 SQL 级别 1 发生错误

我开始得到以下内容SQL exception我不知道这个异常的根本原因是什么？我也关门了dbconnection and prepared statement也。那么问题出在哪里呢？

java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1
ORA-01000: maximum open cursors exceeded
ORA-00604: error occurred at recursive SQL level 1
ORA-01000: maximum open cursors exceeded
ORA-01000: maximum open cursors exceeded

下面是我正在使用的代码。我的代码有什么问题吗？

for (Entry<Integer, LinkedHashMap<Integer, String>> entry : GUID_ID_MAPPING.entrySet()) {

    pstatement = db_connection.prepareStatement(PDSLnPConstants.UPSERT_SQL); // create a statement
    pstatement.setInt(1, entry.getKey());
    pstatement.setString(2, entry.getValue().get(PDSLnPConstants.CGUID_ID));
    pstatement.setString(3, entry.getValue().get(PDSLnPConstants.PGUID_ID));
    pstatement.setString(4, entry.getValue().get(PDSLnPConstants.SGUID_ID));
    pstatement.setString(5, entry.getValue().get(PDSLnPConstants.UID_ID));
    pstatement.setString(6, entry.getValue().get(PDSLnPConstants.ULOC_ID));
    pstatement.setString(7, entry.getValue().get(PDSLnPConstants.SLOC_ID));
    pstatement.setString(8, entry.getValue().get(PDSLnPConstants.PLOC_ID));
    pstatement.setString(9, entry.getValue().get(PDSLnPConstants.ALOC_ID));
    pstatement.setString(10, entry.getValue().get(PDSLnPConstants.SITE_ID));
    pstatement.executeUpdate();

    }

} catch (SQLException e) {
    getLogger().log(LogLevel.ERROR, e);
} finally {
    if (pstatement!= null) {
    try {
        pstatement.close();
        pstatement = null;
    } catch (SQLException e) {
        getLogger().log(LogLevel.ERROR, e.getMessage(), e.fillInStackTrace());
    }
    }
    if (db_connection!= null) {
    try {
        db_connection.close();
        db_connection = null;
    } catch (SQLException e) {
        getLogger().log(LogLevel.ERROR, e.getMessage(), e.fillInStackTrace());
    }
    }

我觉得PreparedStatement定义应该从循环中取出并通过调用在循环中重用clearParameters:

pstatement = db_connection.prepareStatement(PDSLnPConstants.UPSERT_SQL); // create a statement

for (Entry<Integer, LinkedHashMap<Integer, String>> entry : GUID_ID_MAPPING.entrySet()) {

    pstatement.setInt(1, entry.getKey());
    pstatement.setString(2, entry.getValue().get(PDSLnPConstants.CGUID_ID));
    pstatement.setString(3, entry.getValue().get(PDSLnPConstants.PGUID_ID));
    pstatement.setString(4, entry.getValue().get(PDSLnPConstants.SGUID_ID));
    pstatement.setString(5, entry.getValue().get(PDSLnPConstants.UID_ID));
    pstatement.setString(6, entry.getValue().get(PDSLnPConstants.ULOC_ID));
    pstatement.setString(7, entry.getValue().get(PDSLnPConstants.SLOC_ID));
    pstatement.setString(8, entry.getValue().get(PDSLnPConstants.PLOC_ID));
    pstatement.setString(9, entry.getValue().get(PDSLnPConstants.ALOC_ID));
    pstatement.setString(10, entry.getValue().get(PDSLnPConstants.SITE_ID));
    pstatement.executeUpdate();

    pstatement.clearParameters();

}

您可能还想研究批处理（addBatch）。如果您正在测试，您可能需要等待一段时间才能清理现有的“打开”游标。
