Python and SQLite: insert into table

People also ask

How do I populate a SQLite database in Python?

First, connect to the SQLite database by creating a Connection object. Second, create a Cursor object by calling the cursor method of the Connection object. Third, execute an INSERT statement. If you want to pass arguments to the INSERT statement, you use the question mark (?) as the placeholder for each argument.

How manually insert data in SQLite database?

If you want to inset the data manually(fully graphical) do the following: Go to the DDMS perspective. File explorer (tab-menu) Locate your db (/data/data/com.


there's a better way

# Larger example
rows = [('2006-03-28', 'BUY', 'IBM', 1000, 45.00),
        ('2006-04-05', 'BUY', 'MSOFT', 1000, 72.00),
        ('2006-04-06', 'SELL', 'IBM', 500, 53.00)]
c.executemany('insert into stocks values (?,?,?,?,?)', rows)
connection.commit()

conn = sqlite3.connect('/path/to/your/sqlite_file.db')
c = conn.cursor()
for item in my_list:
  c.execute('insert into tablename values (?,?,?)', item)

Not a direct answer, but here is a function to insert a row with column-value pairs into sqlite table:

def sqlite_insert(conn, table, row):
    cols = ', '.join('"{}"'.format(col) for col in row.keys())
    vals = ', '.join(':{}'.format(col) for col in row.keys())
    sql = 'INSERT INTO "{0}" ({1}) VALUES ({2})'.format(table, cols, vals)
    conn.cursor().execute(sql, row)
    conn.commit()

Example of use:

sqlite_insert(conn, 'stocks', {
        'created_at': '2016-04-17',
        'type': 'BUY',
        'amount': 500,
        'price': 45.00})

Note, that table name and column names should be validated beforehand.

for t in [('2006-03-28', 'BUY', 'IBM', 1000, 45.00),
          ('2006-04-05', 'BUY', 'MSOFT', 1000, 72.00),
          ('2006-04-06', 'SELL', 'IBM', 500, 53.00),
         ]:
    c.execute('insert into stocks values (?,?,?,?,?)', t)
