USE [TutorialDB]
-- Create a new table called 'Customers' in schema 'dbo'
-- Drop the table if it already exists
IF OBJECT_ID('dbo.Customers', 'U') IS NOT NULL
DROP TABLE dbo.Customers
-- Create the table in the specified schema
CREATE TABLE dbo.Customers
CustomerId INT NOT NULL PRIMARY KEY, -- primary key column
Name [NVARCHAR](50) NOT NULL,
Location [NVARCHAR](50) NOT NULL,
Email [NVARCHAR](50) NOT NULL
插入数据:
-- Insert rows into table 'Customers'
INSERT INTO dbo.Customers
([CustomerId],[Name],[Location],[Email])
VALUES
( 1, N'Orlando', N'Australia', N''),
( 2, N'Keith', N'India', N'[email protected]'),
( 3, N'Donna', N'Germany', N'[email protected]'),
( 4, N'Janet', N'United States', N'[email protected]')
查询数据:
-- Select rows from table 'Customers'
SELECT * FROM dbo.Customers;
由此可以看到,创建表、数据插入、查询成功。如下截图。
USE [TutorialDB1]
-- Create a new table called 'Customers' in schema 'dbo'
-- Drop the table if it already exists
IF OBJECT_ID('dbo.Customers', 'U') IS NOT NULL
DROP TABLE dbo.Customers
-- Create the table in the specified schema
CREATE TABLE dbo.Customers
CustomerId INT NOT NULL PRIMARY KEY, -- primary key column
Name [NVARCHAR](50) NOT NULL,
Location [NVARCHAR](50) NOT NULL,
Email [NVARCHAR](50) NOT NULL
-- Insert rows into table 'Customers'
INSERT INTO dbo.Customers
([CustomerId],[Name],[Location],[Email])
VALUES
( 1, N'Orlando', N'Australia', N''),
( 2, N'Keith', N'India', N'[email protected]'),
( 3, N'Donna', N'Germany', N'[email protected]'),
( 4, N'Janet', N'United States', N'[email protected]')
创建第2个数据库TutorialDB2
并插入数据:
USE master
IF NOT EXISTS (
SELECT name
FROM sys.databases
WHERE name = N'TutorialDB2'
CREATE DATABASE [TutorialDB2]
USE [TutorialDB2]
-- Create a new table called 'Customers' in schema 'dbo'
-- Drop the table if it already exists
IF OBJECT_ID('dbo.Customers', 'U') IS NOT NULL
DROP TABLE dbo.Customers
-- Create the table in the specified schema
CREATE TABLE dbo.Customers
CustomerId INT NOT NULL PRIMARY KEY, -- primary key column
Name [NVARCHAR](50) NOT NULL,
Location [NVARCHAR](50) NOT NULL,
Email [NVARCHAR](50) NOT NULL
-- Insert rows into table 'Customers'
INSERT INTO dbo.Customers
([CustomerId],[Name],[Location],[Email])
VALUES
( 1, N'Orlando', N'Australia', N''),
( 2, N'Keith', N'India', N'[email protected]'),
( 3, N'Donna', N'Germany', N'[email protected]'),
( 4, N'Janet', N'United States', N'[email protected]')
数据插入成功。且可以通过SQL Server Management Studio(SSMS)看到其中的两个数据库的Schema和Table。如下截图。
