我构建了一个 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 SQL 准备好的语句，该语句填充一个名为 XMLInsertion 的表，该语句又激活一个 SQL 触发器，该触发器从 XML 文件中进行批量读取并更新 XMLInsertion 和另一个表 WeedingReports。这一切都很顺利，直到几天前我打开它，所以在此期间发生了一些事情。
如果 SQL 触发器被禁用，准备好的语句将起作用。如果我启用触发器都不起作用，并出现错误“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无法通过插件工作，那么这怎么可能，因为错误表明触发器找不到文件，但触发器需要从未填充的 XMLInsertion 中读取数据来激活触发器 - 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，那么错误是如何发生的？该错误与 BULK LOAD 有关，该错误位于触发器内，但触发器依赖于从准备好的语句中输入的数据，而该语句永远不会执行。
为什么只有在启用触发器时，准备好的语句才根本不运行？
Connection connection = DriverManager.getConnection("jdbc:sqlserver://gissrv;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();
直到几天前它都工作正常，所以我想有人更改了权限，因为我自己没有进行任何更改。

我使用 C++ sqlite 绑定(bind)遇到了一个极其相似的问题。如果触发器在 BEGIN ... END 中有任何拼写错误；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拼写错误，它似乎仍然添加了触发器，但准备将值插入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，以确保其中没有拼写错误。
关于java - 启用 SQL 触发器时，Java 中的准备语句失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43714887/
