Using a Python dict for a SQL INSERT statement

Question

I am trying to use a dict to do a SQL INSERT. The logic would basically be:

INSERT INTO table (dict.keys()) VALUES dict.values()


        

Answer 1

What about:

keys = str(dict.keys())
keys.replace('[', '(')
keys.replace(']', ')')
keys.replace("'",'')

vals = str(dict.values())
vals.replace('[', '(')
vals.replace(']', ')')

cur.execute('INSERT INTO table %s VALUES %s' % (keys, vals))

For python 3:

keys = str(dict.keys())[9:].replace('[', '').replace(']', '')
vals = str(dict.values())[11:].replace('[', '').replace(']', '')

...

Answer 2

This code worked for me (Python 3):

fields = (str(list(dictionary.keys()))[1:-1])
values = (str(list(dictionary.values()))[1:-1])
sql = 'INSERT INTO Table (' + fields + ') VALUES (' + values + ')'
cursor.execute(sql)

It does rely on the dictionary outputting its keys and values in the same order. I'm unclear if this is always true :)

Answer 3

table='mytable'    
columns_string= '('+','.join(myDict.keys())+')'    
values_string = '('+','.join(map(str,myDict.values()))+')'    
sql = """INSERT INTO %s %s
     VALUES %s"""%(table, columns_string,values_string)

Answer 4

You want to add parameter placeholders to the query. This might get you what you need:

qmarks = ', '.join('?' * len(myDict))
qry = "Insert Into Table (%s) Values (%s)" % (qmarks, qmarks)
cursor.execute(qry, myDict.keys() + myDict.values())
