Updating Data
For updating the data in the SQLite3 table we will use the UPDATE statement. We can update single columns as well as multiple columns using the UPDATE statement as per our requirement.
UPDATE table_name SET column1 = value1, column2 = value2,… WHERE condition;
In the above syntax, the SET statement is used to set new values to the particular column, and the WHERE clause is used to select the rows for which the columns are needed to be updated.
Example: Updating SQLite3 table using Python
Python3
# Import moduleimport sqlite3# Connecting to sqliteconn = sqlite3.connect('gfg.db')# Creating a cursor object using# the cursor() methodcursor = conn.cursor()# Updatingcursor.execute('''UPDATE emp SET lname = "Jyoti" WHERE fname="Rishabh";''')# Commit your changes in the databaseconn.commit()# Closing the connectionconn.close() |

SQL using Python
In this article, integrating SQLite3 with Python is discussed. Here we will discuss all the CRUD operations on the SQLite3 database using Python. CRUD contains four major operations –
Note: This needs a basic understanding of SQL.
Here, we are going to connect SQLite with Python. Python has a native library for SQLite3 called sqlite3. Let us explain how it works.
