show creat table user

Sure, here is an example of a SQL statement to create a table named "user":
```sql
CREATE TABLE user (
id INT PRIMARY KEY,
username VARCHAR(50) NOT NULL,
email VARCHAR(100) NOT NULL,
password VARCHAR(100) NOT NULL,
created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
```
In this example, the "user" table has five columns: "id", "username", "email", "password", and "created_at". The "id" column is the primary key, which uniquely identifies each record in the table. The other columns store the user's username, email, password, and the timestamp of when the record was created.

creat table
您好,关于 "creat table" 的问题,我可以回答。在 Lua 编程语言中,可以使用 "table" 关键字来创建一个新的表。例如,以下代码可以创建一个名为 "myTable" 的空表:
myTable = {}
您可以在表中存储键值对,例如:
myTable["key1"] = "value1"
myTable["key2"] = "value2"
您还可以使用以下语法来创建一个带有初始值的表:
myTable = {key1="value1", key2="value2"}
希望这个回答能够帮到您。
python creat table
创建表在Python中可以使用SQL语句,在SQLite数据库中可以使用SQLite库来执行SQL语句。例如,使用以下代码创建一个名为students的表:
```
import sqlite3
# 连接到SQLite数据库
conn = sqlite3.connect('test.db')
# 创建一个游标对象
cursor = conn.cursor()
# 创建students表的SQL语句
create_table_sql = '''
CREATE TABLE students (
id INT PRIMARY KEY NOT NULL,
name TEXT NOT NULL,
age INT NOT NULL,
sex CHAR(10)
);
'''
# 执行SQL语句
cursor.execute(create_table_sql)
# 关闭游标和连接
cursor.close()
conn.close()
```
这个例子创建了一个包含id、name、age和sex四个字段的students表。其中id是主键,不能为空。执行execute(create_table_sql)语句后,students表就被创建了。
