实体框架核心 - 更改“__EFMigrationsHistory”表的模式

Question

是否可以在EntityFramework Core中更改__EFMigrationsHistory表的架构？

Answer 1

在致电UseSqlServer时这样做。

optionsBuilder
    .UseSqlServer(
        "...",
        x => x.MigrationsHistoryTable(
            HistoryRepository.DefaultTableName,
            "mySchema"));

Answer 2

查看源代码（HistoryRepository.cs）。您可以在DbContext constructor

中配置自定义迁移表和模式名称

public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
{
    var relationalOptions = RelationalOptionsExtension.Extract(options);
    relationalOptions.MigrationsHistoryTableName = "bar";
    relationalOptions.MigrationsHistoryTableSchema = "foo";
}

或OnConfiguring method

内

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    var relationalOptions = RelationalOptionsExtension.Extract(optionsBuilder.Options);
    relationalOptions.MigrationsHistoryTableName = "bar";
    relationalOptions.MigrationsHistoryTableSchema = "foo";
}
