# Sqlite3 Module
# Sqlite3 - Not require separate server process.
The sqlite3 module was written by Gerhard Häring. To use the module, you must first create a Connection object that represents the database. Here the data will be stored in the example.db file:
import sqlite3 conn = sqlite3.connect('example.db')
You can also supply the special name :memory: to create a database in RAM. Once you have a Connection, you can create a Cursor object and call its execute() method to perform SQL commands:
c = conn.cursor() # Create table c.execute('''CREATE TABLE stocks (date text, trans text, symbol text, qty real, price real)''') # Insert a row of data c.execute("INSERT INTO stocks VALUES ('2006-01-05','BUY','RHAT',100,35.14)") # Save (commit) the changes conn.commit() # We can also close the connection if we are done with it. # Just be sure any changes have been committed or they will be lost. conn.close()
# Getting the values from the database and Error handling
Fetching the values from the SQLite3 database.
Print row values returned by select query
import sqlite3 conn = sqlite3.connect('example.db') c = conn.cursor() c.execute("SELECT * from table_name where id=cust_id") for row in c: print row # will be a list
To fetch single matching fetchone() method
For multiple rows use fetchall() method
a=c.fetchall() #which is similar to list(cursor) method used previously for row in a: print row
Error handling can be done using sqlite3.Error built in function
try: #SQL Code except sqlite3.Error as e: print "An error occurred:", e.args
