mysql中select带有变量的数据表
如果你想在MySQL的SELECT语句中使用变量来指定数据表名,可以使用字符串拼接或字符串插值的方式来构建动态SQL语句。以下是一个示例代码:
```python
import mysql.connector
# 建立数据库连接
db = mysql.connector.connect(
host="localhost",
user="yourusername",
password="yourpassword",
database="yourdatabase"
# 创建游标对象
cursor = db.cursor()
# 定义变量和数据表名
table_name = "your_table_name"
query = f"SELECT * FROM {table_name}"
# 执行查询
cursor.execute(query)
# 获取查询结果
result = cursor.fetchall()
# 遍历结果并输出
for row in result:
print(row)
# 关闭游标和数据库连接
cursor.close()
db.close()
在这个例子中,我们使用了字符串插值(
Mysql的列名可以带空格吗

CREATE TABLE my_table (
`column name with space` VARCHAR(50),
