Spring boot 模式'；SA'；不存在

获取错误，说明架构“SA”不存在。从H2过渡到Derby，所以我保留了每个人都使用的原始SA用户名。我的意图是使用Derby作为内存中数据库来建模DB/2 LUW。在主代码中，DB/2端加载了Flyway迁移。我也希望对内存中的数据库执行同样的操作，尝试了H2，但停止了，因为一些CREATETABLE语句在H2下无法工作，即使在DB/2兼容模式下也是如此

注意：由于IP原因，我更改了一些路径

基本上，它似乎试图执行迁移，但失败了，因为没有SA模式。我可以理解没有SA模式，但这不是H2的问题，它只是创建了它。如何在Flyway之前创建模式？我不想更改我的flyway脚本

堆栈跟踪是：
