Question

我正在创建一个理发店数据库，该数据库围绕主表和子表的概念。在产品表中，我在主表的列上显示税收（货币格式），但有一些条件。稍后将一个外键从主表添加到＆＃34; tax＆＃34;上的子表。柱。我该怎么写呢？

希望这个例子可以帮到你

 USE COSTUMERENTAL;

    CREATE TABLE dbo.CATEGORY  -- should always specify schema
    (
        CATEGORY_ID       CHAR(5)    PRIMARY KEY, -- can't be two data types
        CATEGORY_DESC     CHAR(50)   NOT NULL
    ); -- don't need to specify PRIMARY KEY twice

    --USE COSTUMER RENTAL; -- is there a space in the name or not?

    CREATE TABLE dbo.COSTUME
    (
        Costume_ID              CHAR(5), -- need commas
        Costume_Desc            CHAR(50), 
        Costume_Size            CHAR(5),
        Costume_RentalPricE     DECIMAL(12,2), -- Number isn't a valid SQL Server data type  
        Category_ID             CHAR(5)
    ); -- need closing brackets; also should always use semi-colons to terminate

如何在sql server 2012中创建数据库？
