Question

我正在尝试使用一些数据来播种数据库。我得到的错误是在布尔值和日期字段上。下面是播种数据库的示例种子数据。我做错了什么？

 Sql("INSERT INTO USERS (Id,FirstName,LastName,Email,RefIndicator,TeamId,IsRegistered,DateRegistered,LastModified,UserRolesId) VALUES (1, 'SomeFirstName', 'SomeSurName', 'name@somedomainname.com', 'IMT/iTC22', 1, True, convert(datetime, '17/07/2017 17:56:25'), null, 1)");
 Sql("INSERT INTO USERS (Id,FirstName,LastName,Email,RefIndicator,TeamId,IsRegistered,DateRegistered,LastModified,UserRolesId) VALUES (2, 'SomeFirstName', 'SomeSurName', 'name@somedomainname.com', 'IMT/iTC22', 1, True, convert(datetime, '17/07/2017 17:56:25'), null, 2)");
 Sql("INSERT INTO USERS (Id,FirstName,LastName,Email,RefIndicator,TeamId,IsRegistered,DateRegistered,LastModified,UserRolesId) VALUES (3, 'SomeFirstName', 'SomeSurName', 'name@somedomainname.com', 'IMT/iTC22', 1, True, convert(datetime, '17/07/2017 17:56:25'), null, 3)");

下面是我需要填充种子数据的表格结构

CREATE TABLE [dbo].[Users] (
                        [Id]             TINYINT        NOT NULL,
                        [FirstName]      NVARCHAR (MAX) NULL,
                        [LastName]       NVARCHAR (MAX) NULL,
                        [Email]          NVARCHAR (MAX) NULL,
                        [RefIndicator]   NVARCHAR (MAX) NULL,
                        [TeamId]         TINYINT        NOT NULL,
                        [IsRegistered]   BIT            NOT NULL,
                        [DateRegistered] DATETIME       NOT NULL,
                        [LastModified]   DATETIME       NULL,
                        [UserRolesId]    TINYINT        DEFAULT ((0)) NOT NULL,
                        CONSTRAINT [PK_dbo.Users] PRIMARY KEY CLUSTERED ([Id] ASC),
                        CONSTRAINT [FK_dbo.Users_dbo.Teams_TeamId] FOREIGN KEY ([TeamId]) REFERENCES [dbo].[Teams] ([Id]) ON DELETE CASCADE,
                        CONSTRAINT [FK_dbo.Users_dbo.UserRoles_UserRolesId] FOREIGN KEY ([UserRolesId]) REFERENCES [dbo].[UserRoles] ([Id]) ON DELETE CASCADE
                    );


                    GO
                    CREATE NONCLUSTERED INDEX [IX_TeamId]
                        ON [dbo].[Users]([TeamId] ASC);


                    GO
                    CREATE NONCLUSTERED INDEX [IX_UserRolesId]
                        ON [dbo].[Users]([UserRolesId] ASC);

Answer 1

您正尝试将值True插入IsRegistered类bit列。您正在执行脚本字符串，因此未发送C＃布尔值true，但正在发送未包含在单引号中的字符串True 。这就是两个值都抛出错误的原因。

将您的True替换为字符串中的1，您就可以了。

我使用下面的代码成功播种了数据库

        Sql("INSERT INTO USERS (Id,FirstName,LastName,Email,RefIndicator,TeamId,IsRegistered,DateRegistered,LastModified,UserRolesId) VALUES (1, 'SampleName', 'SampleSurname', 'someNames@nnxg.com', 'IMT/iTC22', 1, 'True', GETDATE(), null, 1)");
        Sql("INSERT INTO USERS (Id,FirstName,LastName,Email,RefIndicator,TeamId,IsRegistered,DateRegistered,LastModified,UserRolesId) VALUES (2, 'SampleName', 'SampleSurname', 'someNames@nnxg.com', 'IMT/iTC22', 1, 'True', GETDATE(), null, 2)");
        Sql("INSERT INTO USERS (Id,FirstName,LastName,Email,RefIndicator,TeamId,IsRegistered,DateRegistered,LastModified,UserRolesId) VALUES (3, 'SampleName', 'SampleSurname', 'someNames@nnxg.com', 'IMT/iTC22', 1, 'True', GETDATE(), null, 3)");

我将True的字符串值更改为布尔值＆＃39; True＆＃39;并且还使用GETDATE（）函数将当前日期时间值插入数据库。我从这个post

中选择了日期解决方案

使用EF-CodeFirst种子数据
