我有一个随机生成的问题(千分之一调用之间的一次)。错误ORA-01722:在准备好的语句 Oracle 数据库中执行 sql update 时以随机方式生成无效数字。案件详情如下:
try {
connection = getConnection();
statement = connection.prepareStatement(sql);
for (int i = 0; i < params.length; i++) {
if (params[i] instanceof Date) {
statement.setTimestamp(i + 1, new Timestamp(((Date) params[i]).getTime()));
} else if (params[i] instanceof java.util.Date) {
statement.setTimestamp(i + 1, new Timestamp(((java.util.Date) params[i]).getTime()));
} else {
statement.setObject(i + 1, params[i]);
}
paramsBuilder.append(": " + params[i]);
}
if (logger.isInfoEnabled()) {
logger.info("Query String [" + sql + "] [" + paramsBuilder + "]");
logger.info("Query Parameters [" + paramsBuilder + "]");
}
result = statement.executeUpdate();
if (logger.isInfoEnabled()) {
logger.info(result + " rows affected");
}
} catch (SQLException e) {
if (logger.isInfoEnabled()) {
String message = "Failed to execute SQL statment [" + sql + "] with parameters [" + paramsBuilder + "]";
logger.error(message, e);
}
throw new DAOException(e);
}
日志中的值是这样的:
Failed to execute SQL statment [update CUSTOMER_CASE set no_of_ptp=?, no_of_unreached=?,collector_name=? , last_case_status_history_id=?, current_handler=?, handling_start_time=?,due_total_open_amount=?, payment_due_invoice_id =? where id=?] with parameters [: 0: 0: auto: 5470508: null: null: 0.0: 23410984: 2476739] java.sql.SQLException: ORA-01722: invalid number
通过在 DB 上跟踪查询参数,所有参数都通过 JDBC 驱动程序正确传输,除了参数23410984它被替换为值"<C4>^X*
U"
(注意这个值在 char 'u' 之前包含回车!)。我不知道为什么
