sql必知必会的例子创建(sqlite3)
2022/3/7 2:15:25
本文主要是介绍sql必知必会的例子创建(sqlite3)，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
模仿mysql的创建表的方法，创建了sqlite3的表数据,代码如下：
########################
# Create table
########################
#主键不能通过alter table定义,AUTOINCREMENT必须与主键一起使用
CREATE TABLE customers
(
cust_id INTEGER PRIMARY KEY AUTOINCREMENT,
cust_name char(50) NOT NULL ,
cust_address char(50) NULL ,
cust_city char(50) NULL ,
cust_state char(5) NULL ,
cust_zip char(10) NULL ,
cust_country char(50) NULL ,
cust_contact char(50) NULL ,
cust_email char(255) NULL
);
#外键也不能通过alter table定义，且外键功能必须通过 'PRAGMA foreign_keys = ON'打开
CREATE TABLE orderitems (
order_num INTEGER NOT NULL,
order_item INTEGER NOT NULL,
prod_id CHAR (10) NOT NULL,
quantity INTEGER NOT NULL,
item_price DECIMAL (8, 2) NOT NULL,
PRIMARY KEY (
order_num,
order_item
),
FOREIGN KEY (
order_num
)
REFERENCES orders (order_num) ON DELETE NO ACTION
ON UPDATE NO ACTION,
FOREIGN KEY (
prod_id
)
REFERENCES products (prod_id) ON DELETE NO ACTION
ON UPDATE NO ACTION
);
CREATE TABLE orders (
order_num INTEGER PRIMARY KEY AUTOINCREMENT,
order_date DATETIME NOT NULL,
cust_id INTEGER NOT NULL,
FOREIGN KEY (
cust_id
)
REFERENCES customers (cust_id) ON DELETE NO ACTION
ON UPDATE NO ACTION
);
CREATE TABLE products (
prod_id CHAR (10) NOT NULL,
vend_id INT NOT NULL,
prod_name CHAR (255) NOT NULL,
prod_price DECIMAL (8, 2) NOT NULL,
prod_desc TEXT,
PRIMARY KEY (
prod_id
),
FOREIGN KEY (
vend_id
)
REFERENCES vendors (vend_id) ON DELETE NO ACTION
ON UPDATE NO ACTION
);
CREATE TABLE vendors
(
vend_id INTEGER PRIMARY KEY AUTOINCREMENT,
vend_name char(50) NOT NULL ,
vend_address char(50) NULL ,
vend_city char(50) NULL ,
vend_state char(5) NULL ,
vend_zip char(10) NULL ,
vend_country char(50) NULL
);
#单列的fulltext添加不上
CREATE TABLE productnotes (
note_id INTEGER PRIMARY KEY AUTOINCREMENT,
prod_id CHAR (10) NOT NULL,
note_date DATETIME NOT NULL,
note_text TEXT
);
增加表中记录与原文一致
