首先是實體框架代碼-創建表並將現有表中的數據插入到新創建的表中，

Question

我首先使用EF代碼，我想創建一個新表並將現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");

        }

當我運行此遷移時，它創建了表，但是它是空的。 有誰知道我該怎么辦？

Answer 1

newid（）是否用於uniqueidentifier？ 您可以嘗試在插入語句中刪除該列嗎？

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