Question

当我输入WSO2查询来执行简单的存储过程（sp_xxx exec）时，调用服务时会发生错误，但是当我放入SQL SELECT时它正常工作。有谁知道为什么？

这是错误日志：

有没有人有任何解决方案？

Answer 1

您应该能够使用WSO2数据服务服务器成功执行存储过程。当您遇到上述问题时，能否在控制台或DSS_HOME / repository / logs / wso2carbon.log中打印出错误日志（如果有的话）？

Answer 2

您的问题很可能与此处报告的内容相同：https://wso2.org/jira/browse/DS-550。这已针对即将推出的DSS 3.0.0版本进行了修复。原因是，您使用的是JDBC3驱动程序，但在DSS 2.6.3中，我们使用JDBC4（Java6）功能，因此您应该使用JDBC4驱动程序。但看起来，到目前为止我们专门使用的唯一JDBC4功能（可能会给旧驱动程序带来问题）是ResultSet.isClosed，我们在新版本中为此设置了一个解决方法。如果要修补数据服务核心jar，那么补丁就存在问题，或者只是尝试使用JDBC4驱动程序。
