[英]Rename a Column name in a specific Table in SQL from Python
I'm trying to rename a column name in SQL-Server from Python.我正在尝试从 Python 重命名 SQL-Server 中的列名。
def ModifeingColumnName():
try:
myconn = mysql.connector.connect(host ="localhost" , user = "root" , password = "", database = "test")
mycurs = myconn.cursor()
mycurs.execute('''EXEC SP_RENAME 'test_table.Name','First_Name','COLUMN' ''')
myconn.commit()
print('changed successfully!')
except:
print('failed!')
(test)
我的数据库名称是(test)
(test_table)
我的表是(test_table)
(Name)
我的专栏名称是(Name)
It doesn't work.它不起作用。 It always reached the except block.它总是到达 except 块。
What's the problem?有什么问题?
I'm using SQL and here is the error when i remove the try block :我正在使用 SQL,这是我删除 try 块时的错误:
mysql.connector.errors.ProgrammingError: 1064 (42000): You have an error in your SQL syntax; mysql.connector.errors.ProgrammingError: 1064 (42000): 你的 SQL 语法有错误; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'EXEC SP_RENAME 'test.Name','First_Name','COLUMN'' at line检查与您的 MariaDB 服务器版本相对应的手册,以获取在“EXEC SP_RENAME 'test.Name','First_Name','COLUMN'' 行附近使用的正确语法
you can use it like this:你可以像这样使用它:
# Establish connection to MySQL database
import mysql.connector
db = mysql.connector.connect(
host="localhost", # your host
user="root", # your username
password="root123", # your password
database = "meow" # name of the database
)
mycursor = db.cursor() # cursor() method is used to create a cursor object
query = "ALTER TABLE persons RENAME COLUMN PersonID TO Emp_Id;" # query to rename column
mycursor.execute(query) # execute the query
# close the Connection
db.close()
