首先是实体框架代码-创建表并将现有表中的数据插入到新创建的表中，

Question

我首先使用EF代码，我想创建一个新表并将现有表中的值插入其中。

public override void Up()
        {
            CreateTable(
                "dbo.UserCulture",
                c => new
                {
                    UserCultureId = c.Int(false, true),
                    Id = c.Int(false),
                    IsSelected = c.Boolean(false),
                    Culture = c.String(false, 10),
                    UserLevel = c.Int(false),
                    CurrentScore = c.Int(false),
                    TimelinePercentage = c.String(false, 3),
                    NumberOfGamesPlayed = c.Int(false)

                })
                .PrimaryKey(k => k.UserCultureId)
                .ForeignKey("dbo.AskUser", k => k.Id)
                .Index(t => t.Id);

            Sql("INSERT INTO UserCulture(UserCultureId, Id, IsSelected, Culture, UserLevel, CurrentScore, TimelinePercentage, NumberOfGamesPlayed)" +
                "SELECT newid(), UserId, 1, CreatedCulture, UserLevel, CurrentScore, TimelinePercentage, NumberOfGamesPlayed FROM AskUser");

        }

当我运行此迁移时，它创建了表，但是它是空的。 有谁知道我该怎么办？

Answer 1

newid（）是否用于uniqueidentifier？ 您可以尝试在插入语句中删除该列吗？

Sql("INSERT INTO UserCulture(Id, IsSelected, Culture, UserLevel, CurrentScore, TimelinePercentage, NumberOfGamesPlayed)" +
                "SELECT UserId, 1, CreatedCulture, UserLevel, CurrentScore, TimelinePercentage, NumberOfGamesPlayed FROM AskUser");
