启用 SQL 触发器时,Java 中的 Prepared Statement 失败
Posted
技术标签:
【中文标题】启用 SQL 触发器时,Java 中的 Prepared Statement 失败【英文标题】:Prepared Statement in Java fails when SQL trigger is enabled 【发布时间】:2017-05-01 05:51:51 【问题描述】:我已经构建了一个 Eclipse Java 插件,它具有将选定的 XML 文件复制到服务器的功能,然后运行一个 SQL 准备语句,该语句填充一个名为 XMLInsertion 的表,该表反过来激活一个 SQL 触发器,该触发器从XML 文件和更新 XMLInsertion 和另一个表 WeedingReports。几天前我打开它之前效果很好,所以在此期间发生了一些事情。
如果禁用 SQL 触发器,则准备好的语句将起作用。如果我启用触发器都不起作用,则会出现错误“错误!无法批量加载。文件“blah”不存在。”如果我通过 SQL Server 输入数据,SQL 触发器就会工作。这表明存在权限问题,但是如果触发器或插入都不能通过插件工作,这怎么可能,因为错误表明触发器找不到文件,但触发器需要从 XMLInsertion 中读取,而这不是填充以激活触发器 - 令人困惑?
两个问题
如果准备好的语句或触发器都没有运行,错误是如何发生的?该错误与触发器内的 BULK LOAD 相关,但触发器依赖于从准备好的语句输入的数据,该语句从不执行。
为什么只有在启用触发器时准备好的语句才完全不运行?
Connection connection = DriverManager.getConnection("jdbc:sqlserver://gis-s-rv;databaseName=bushland_dev;user=blah;password=blah;");
PreparedStatement insertXMLTable = connection.prepareStatement("UPDATE Bushland_Dev.dbo.XMLINSERTION SET FILEPATH = ?, FILENAME = ?, TRIGGERFIELD = ? WHERE FILENAME = ?");
insertXMLTable.setString(1,destination.toString());
insertXMLTable.setString(2,destination.getFileName().toString());
insertXMLTable.setString(3,GMSCKey);
insertXMLTable.setString(4,destination.toString());
insertXMLTable.executeUpdate();
直到几天前它还运行良好,所以我想有人更改了权限,因为我自己没有进行任何更改。

【问题讨论】:
所以澄清一下,SQL 准备语句是一个插入到表中的插入,无论触发器与否都应该运行。由于某种原因,启用触发器时都不会运行。我尝试将触发器设置为在 FOR 和 AFTER UPDATE、INSERT 上运行。这没什么区别。插入只是不想在启用触发器的情况下工作。 请包含表和触发器的 DDL。 参见附加的 DDLS。对不起,如果它很长。 【参考方案1】:我在使用 c++ sqlite 绑定时遇到了一个非常相似的问题。如果触发器在 BEGIN ... END 中有任何错字;部分,它实际上仍然允许添加触发器,但会破坏它引用的表。我的触发器中有一个错字,它似乎仍然添加了触发器,但是准备一个将值插入到引用的表之一的语句失败并出现一般逻辑错误。我建议您非常非常仔细地阅读您的触发器,以确保您没有错别字。

以上是关于启用 SQL 触发器时,Java 中的 Prepared Statement 失败的主要内容,如果未能解决你的问题,请参考以下文章
