我在C#中的课程Users
:
public class Users
{
[AutoIncrement]
[PrimaryKey]
public Int32 Id { get; set; }
[StringLength(100)]
[Index(Unique = true)]
public string Username { get; set; }
[StringLength(250)]
public string Password { get; set; }
}
我用过:
db.CreateTable<Users>(overwrite: false);
在数据库中创建表。
调试输出显示:
FirebirdSql.Data.FirebirdClient Information: 0 : Command:
CREATE TABLE Users
(
Id INTEGER NOT NULL,
Username VARCHAR(100),
"Password" VARCHAR(250),
PRIMARY KEY(Id)
);
Parameters:
FirebirdSql.Data.FirebirdClient Information: 0 : Command:
CREATE UNIQUE INDEX uidx_users_username ON Users (Username );
Parameters:
FirebirdSql.Data.FirebirdClient Information: 0 : Command:
CREATE GENERATOR USERS_ID_GEN;
Parameters:
但是当我尝试插入记录时,Firebird会抱怨空Id
字段。
C#:
db.Insert(new Users { Username = "admin", Password = "passwordhere" });
调试输出:
FirebirdSql.Data.FirebirdClient Information: 0 : Command:
INSERT INTO Users (Username,"Password") VALUES (@Username,@Password)
Parameters:
Name:@Username Type:VarChar Used Value:admin
Name:@Password Type:VarChar Used Value:passwordhere
例外:
列ID验证错误,值“ * null * ”
我使用NuGet
格式的最新版本。有人可以帮忙吗?
谢谢
