Python program that use db sqlite1/26/2024 ![]() The explicit management of transactions might be a bit tricky at first, but it can certainly help you make the most of sqlite3. I hope you now have a good understanding of what SQLite is, how you can use it for your Python projects, and how some of its advanced features work. execute ( "SELECT * FROM student" ) for row in findRecords : print (row ) Insert_command (conn, 4, 'Joseph', 'Random' )įindRecords = cursor. Insert_command (conn, 3, 'Stephan', 'Taylor' ) Insert_command (conn, 2, 'Lucy', 'Jacobs' ) Insert_command (conn, 1, 'John', 'Smith' ) execute (create_query ) print ( "Table created!" ) # Insert and Read operation cursor ( ) print ( "Database created!" ) # Create operationĬreate_query = '''CREATE TABLE IF NOT EXISTS student(Ĭursor. connect (dbName, isolation_level = None )Ĭursor = conn. Error as e : print ( "Got an error: ", e ) print ( "Aborting." )Ĭonn = sqlite3. execute (command, (student_id, name, surname, ) )Ĭur. The following code is a rewriting of the previous code, but with the explicit usage of transactions: import sqlite3ĭbName = 'database.db' def insert_command (conn, student_id, name, surname ) :Ĭommand = 'INSERT INTO student VALUES (?, ?, ?)'Ĭur. ![]() By setting isolation_level to None, we force sqlite3 to never open transactions implicitly. This is a great way to generate databases that can be used for testing purposes, as they exist only in RAM. Another way of generating databases using SQLite in Python is to create them in memory. ![]() How? By using the function call nnect(dbName, isolation_level=None) instead of nnect(dbName). The connect function creates a connection to the SQLite database and returns an object to represent it. ![]()
