Error in accessing file uploaded file in google colab

Question

I upload final_half.sqlite file in google colab. While reading the file it is giving me the error as below. Could anyone tell me how to solve this?

DatabaseError: database disk image is malformed

I uploaded the file in google colab as follows

import pandas as pd
import sqlite3
from google.colab import files
uploaded = files.upload()

I checked the status of the uploaded file

for fn in uploaded.keys():
  print('User uploaded file "{name}" with length {length} bytes'.format(
      name=fn, length=len(uploaded[fn])))

User uploaded file "final_half.sqlite" with length 7208960 bytes

for name, data in uploaded.items():
  with open('final_half.sqlite', 'wb') as f:
    f.write(data)
    print ('saved file', name)
    con = sqlite3.connect(name)
    print(con)
    sorted_data = pd.read_sql_query("""SELECT * FROM Reviews_half""", con)

Error:

DatabaseError                             Traceback (most recent call last)
/usr/local/lib/python3.6/dist-packages/pandas/io/sql.py in execute(self, *args, **kwargs)

Change these lines

for name, data in uploaded.items():
  with open('final_half.sqlite', 'wb') as f:
    f.write(data)
    print ('saved file', name)
    con = sqlite3.connect(name)

To just

con = sqlite3.connect('final_half.sqlite')

The file is already saved, you don't need to write it again.
