Python MySQL Delete From By

You can delete records from an existing table by using the "DELETE FROM" statement:

Delete any record where the address is "Mountain 21":

host="localhost", user=" yourusername ", password=" yourpassword ", database="mydatabase" ) mycursor = mydb.cursor()

Important!:

mydb.commit(). It is required to make the changes, otherwise no changes are made to the table. Notice the WHERE clause in the DELETE syntax: The WHERE clause specifies which record(s) that should be deleted. If you omit the WHERE clause, all records will be deleted!

It is considered a good practice to escape the values of any query, also in delete statements. This is to prevent SQL injections, which is a common web hacking technique to destroy or misuse your database. The mysql.connector module uses the placeholder %s to escape values in the delete statement:

%s method:

host="localhost", user=" yourusername ", password=" yourpassword ", database="mydatabase" )

mycursor.execute(sql, adr) mydb.commit()
