我刚刚执行了一个干净的操作,我在 prop 文件中添加了一个新模式,然后再次运行 clean 以从 db 中删除该模式,然后当我尝试进行迁移时,它不允许我得到以下信息:
Creating Metadata table: [xx].[schema_version]
Error executing statement at line 17: CREATE TABLE [xx].[schema_version] (
[version_rank] INT NOT NULL,
[installed_rank] INT NOT NULL,
[version] NVARCHAR(50) NOT NULL,
[description] NVARCHAR(200),
[type] NVARCHAR(20) NOT NULL,
[script] NVARCHAR(1000) NOT NULL,
[checksum] INT,
[installed_by] NVARCHAR(30) NOT NULL,
[installed_on] DATETIME NOT NULL DEFAULT GETDATE(),
[execution_time] INT NOT NULL,
[success] BIT NOT NULL
);
CREATE INDEX [schema_version_vr_idx] ON [xx].[schema_version] ([version_rank]);
CREATE INDEX [schema_version_ir_idx] ON [xx].[schema_version] ([installed_rank]);
CREATE INDEX [schema_version_s_idx] ON [xx].[schema_version] ([success]);
另外,当我尝试初始化它时,我会得到以下信息:

请注意我已经删除了所有对象,并且我可以确认它们在我的数据库实例中不存在。
我该如何克服呢?我担心在开发和生产环境中使用该工具时,我们不能只删除数据库实例并重新开始。此时我无法使用该工具进行迁移,我不想删除数据库来解决这个问题。
