13.13.6.1 Using shortcut methods

Using the nonstandard execute, executemany and executescript methods of the Connection object, your code can be written more concisely, because you don't have to create the - often superfluous Cursor objects explicitly. Instead, the Cursor objects are created implicitly and these shortcut methods return the cursor objects. This way, you can for example execute a SELECT statement and iterate over it directly using only a single call on the Connection object.

import sqlite3

persons = [
    ("Hugo", "Boss"),
    ("Calvin", "Klein")
    ]

con = sqlite3.connect(":memory:")

# Create the table
con.execute("create table person(firstname, lastname)")

# Fill the table
con.executemany("insert into person(firstname, lastname) values (?, ?)", persons)

# Print the table contents
for row in con.execute("select firstname, lastname from person"):
    print row

# Using a dummy WHERE clause to not let SQLite take the shortcut table deletes.
print "I just deleted", con.execute("delete from person where 1=1").rowcount, "rows"
