如何打开DDL事务支持？

Question

我刚开始使用flywaydb，只是一个测试试图与创建和插入查询，并发射了迁移，但它忽略了我所有的创建表脚本:(

我用于调试-X选项，发现了一个奇怪的线 DEBUG: DDL Transactions Supported: false

看来，如果我做到了真正的，它会工作。

有谁遇到这个问题，如果是如何摆脱呢？ 我已经做了这个新的架构，用干净的-INIT-迁移 下面全堆栈跟踪：

这只是表示您的数据库不支持DDL事务。如果需要，可以使用不同的PostgreSQL，DB2或SqlServer。

现在，为什么你的脚本就不会被拾起，这是不可能的从你的问题告诉。

从入门教程开始，一旦成功，将其调整到您的项目。
