To Update a Table

This is the python mysql update module of our entire python MySQL tutorial. And while using

this programming language, If you wish to update any particular table then you can easily do

that. To accomplish this task it is recommended that you should use the “UPDATE” statement.

If you wish to make some changes in the address column by changing the address from ‘Valley

345’ to ‘Canyon 123’ then the python update sql server table example for this is mentioned

below.

 

 

It is important for you to focus on the statement of mydb.commit ( ). The focus is required on

this statement because of the fact that if you fail to use this statement then you won’t be able

to make any changes in the python sql update table at all. It is always important for you to

remember that to make any particular changes in a table you need to use this statement. You

should also focus on the WHERE clause of the UPDATE syntax. This clause that is used here

plays a very important role as this clause helps in specifying the record that needs to be

updated. If you fail to use this clause then all of the records will be updated and changed.

 

To Prevent SQL Injection

As we have mentioned before this python sql update table tutorial module, that it is always a

good idea to escape a query value. This particular statement is also true for the case of the

update statements. This particular step is taken so any kind of SQL injection that might occur

can be avoided.

This SQL injection that we just mentioned is nothing but a common web hacking technique. This

web hacking technique is used by hackers from all across the world to misuse or destroy the

data that you have stored in your database. It is also important for you to remember that in the

mysql.connector module you need to use the placeholder %s to escape any kind of value when

it comes to the delete statement. The python update sql server table example for this is

mentioned below.

 


With this, we finish the Python mysql update part of our entire Python MySQL tutorial.
