ASP.NET MVC 5 Identity, Users, Roles, Accounts, SQL to Generate Tables

In ASP.NET MVC 5, user management changed significantly from ASP.NET MVC 4.

This is the start of a series of blog posts on the topic (long overdue).

This post is on the SQL that your website executes to initially create the identity (user, role) tables.

The SQL the ApplicationUserManager and ApplicationSigninManager generate and execute is below:



CREATE TABLE [dbo].[AspNetRoles] (
    [Id] [nvarchar](128) NOT NULL,
    [Name] [nvarchar](256) NOT NULL,
    CONSTRAINT [PK_dbo.AspNetRoles] PRIMARY KEY ([Id])
)
go
CREATE TABLE [dbo].[AspNetUserRoles] (
    [UserId] [nvarchar](128) NOT NULL,
    [RoleId] [nvarchar](128) NOT NULL,
    CONSTRAINT [PK_dbo.AspNetUserRoles] PRIMARY KEY ([UserId], [RoleId])
)
go
CREATE TABLE [dbo].[AspNetUsers] (
    [Id] [nvarchar](128) NOT NULL,
    [Email] [nvarchar](256),
    [EmailConfirmed] [bit] NOT NULL,
    [PasswordHash] [nvarchar](max),
    [SecurityStamp] [nvarchar](max),
    [PhoneNumber] [nvarchar](max),
    [PhoneNumberConfirmed] [bit] NOT NULL,
    [TwoFactorEnabled] [bit] NOT NULL,
    [LockoutEndDateUtc] [datetime],
    [LockoutEnabled] [bit] NOT NULL,
    [AccessFailedCount] [int] NOT NULL,
    [UserName] [nvarchar](256) NOT NULL,
    CONSTRAINT [PK_dbo.AspNetUsers] PRIMARY KEY ([Id])
)
go
CREATE TABLE [dbo].[AspNetUserClaims] (
    [Id] [int] NOT NULL IDENTITY,
    [UserId] [nvarchar](128) NOT NULL,
    [ClaimType] [nvarchar](max),
    [ClaimValue] [nvarchar](max),
    CONSTRAINT [PK_dbo.AspNetUserClaims] PRIMARY KEY ([Id])
)
go
CREATE TABLE [dbo].[AspNetUserLogins] (
    [LoginProvider] [nvarchar](128) NOT NULL,
    [ProviderKey] [nvarchar](128) NOT NULL,
    [UserId] [nvarchar](128) NOT NULL,
    CONSTRAINT [PK_dbo.AspNetUserLogins] PRIMARY KEY ([LoginProvider], [ProviderKey], [UserId])
)
go
CREATE UNIQUE INDEX [RoleNameIndex] ON [dbo].[AspNetRoles]([Name])
go
CREATE INDEX [IX_UserId] ON [dbo].[AspNetUserRoles]([UserId])
go
CREATE INDEX [IX_RoleId] ON [dbo].[AspNetUserRoles]([RoleId])
go
CREATE UNIQUE INDEX [UserNameIndex] ON [dbo].[AspNetUsers]([UserName])
go
CREATE INDEX [IX_UserId] ON [dbo].[AspNetUserClaims]([UserId])
go
CREATE INDEX [IX_UserId] ON [dbo].[AspNetUserLogins]([UserId])
go
ALTER TABLE [dbo].[AspNetUserRoles] ADD CONSTRAINT [FK_dbo.AspNetUserRoles_dbo.AspNetRoles_RoleId] FOREIGN KEY ([RoleId]) REFERENCES [dbo].[AspNetRoles] ([Id]) ON DELETE CASCADE
go
ALTER TABLE [dbo].[AspNetUserRoles] ADD CONSTRAINT [FK_dbo.AspNetUserRoles_dbo.AspNetUsers_UserId] FOREIGN KEY ([UserId]) REFERENCES [dbo].[AspNetUsers] ([Id]) ON DELETE CASCADE
go
ALTER TABLE [dbo].[AspNetUserClaims] ADD CONSTRAINT [FK_dbo.AspNetUserClaims_dbo.AspNetUsers_UserId] FOREIGN KEY ([UserId]) REFERENCES [dbo].[AspNetUsers] ([Id]) ON DELETE CASCADE
go
ALTER TABLE [dbo].[AspNetUserLogins] ADD CONSTRAINT [FK_dbo.AspNetUserLogins_dbo.AspNetUsers_UserId] FOREIGN KEY ([UserId]) REFERENCES [dbo].[AspNetUsers] ([Id]) ON DELETE CASCADE
go

Hope this helps,
