To use Dapper Extensions, we need to create a database first, and then we will perform various database operations using the Dapper Extensions library.
The SQL CREATE DATABASE
statement is used to create a new SQL database.
USE [master]
GO
CREATE DATABASE [BookStoreDb]
GO
USE [BookStoreDb]
GO
CREATE TABLE [dbo].[Authors](
[Id] [int] IDENTITY(1,1) NOT NULL,
[FirstName] [nvarchar](450) NULL,
[LastName] [nvarchar](450) NULL,
CONSTRAINT [PK_Authors] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[Books](
[Id] [int] IDENTITY(1,1) NOT NULL,
[Title] [nvarchar](450) NULL,
[Category] [nvarchar](max) NULL,
[AuthorId] [int] NOT NULL,
CONSTRAINT [PK_Books] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
It will create a BookStoreDb
database that contains two tables. Now we need to insert some data into these tables, which can be used later.
The following SQL statements insert new records in the Authors and Books tables.
USE [BookStoreDb]
GO
INSERT INTO Authors(FirstName, LastName) VALUES ('Cardinal','Tom B. Erichsen');
INSERT INTO Authors(FirstName, LastName) VALUES ('William','Shakespeare');
INSERT INTO Authors(FirstName, LastName) VALUES ('Robert','T. Kiyosaki');
INSERT INTO Books(Title, Category, AuthorId) VALUES ('Introduction to Machine Learning', 'Software', 1);
INSERT INTO Books(Title, Category, AuthorId) VALUES ('Introduction to Computing', 'Software', 1);
INSERT INTO Books(Title, Category, AuthorId) VALUES ('Romeo and Juliet', 'Humor & Entertainment', 2);
INSERT INTO Books(Title, Category, AuthorId) VALUES ('The Tempest', 'Fiction', 2);
INSERT INTO Books(Title, Category, AuthorId) VALUES ('The Winter''s Tale : Third Series', 'Fiction', 2);
INSERT INTO Books(Title, Category, AuthorId) VALUES ('Rich Dad, Poor Dad', 'Economics', 3);
Let's try the following queries to test the data in the database.
Select * From Authors;
Select * From Books;
Let's click on the Execute button, and you will see the results of the above queries.
