Python MySQL Drop Table
删除表
您可以使用 "DROP TABLE" 语句来删除已有的表：
示例代码：
删除 "customers" 表：
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword",
database="mydatabase"
)
mycursor = mydb.cursor()
sql = "DROP TABLE customers"
mycursor.execute(sql)
完整实例：
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="myusername",
passwd="mypassword",
database="mydatabase"
)
mycursor = mydb.cursor()
sql = "DROP TABLE customers"
mycursor.execute(sql)
#If this page was executed with no error(s), you have successfully deleted the "customers" table.只在表存在时删除
如果要删除的表已被删除，或者由于任何其他原因不存在，那么可以使用 IF EXISTS 关键字以避免出错。
示例代码：
删除表 "customers" （如果存在）：
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword",
database="mydatabase"
)
mycursor = mydb.cursor()
sql = "DROP TABLE IF EXISTS customers"
mycursor.execute(sql)
完整实例：
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="myusername",
passwd="mypassword",
database="mydatabase"
)
mycursor = mydb.cursor()
sql = "DROP TABLE IF EXISTS customers"
mycursor.execute(sql)
#If this page was executed with no error(s), you have successfully deleted the "customers" table.
