Trying to query for dates in an Access DB, and it keeps returning the follow error:

Here is my code:
import pypyodbc
DBfile = (r'C:\Users\sniederriter\Desktop\SATGexpenses.accdb')
conn = pypyodbc.connect(r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ='+DBfile)
cursor = conn.cursor()
print(DBfile)
SQL = 'SELECT Date * FROM 20142015;'
for row in cursor.execute(SQL):
print (row.Date)
cursor.close()
conn.close()
Your MySQL query is wrong. Following code selects all fields from the table:
SELECT * FROM Table
If you want specific fields write:
SELECT field1, field2, field3 FROM table
But only do one of the things. Either all or specified fields.

I want to export MYSQLdb tables into .csv format.
I tried this:
connection = MySQLdb.connect(host='localhost',
user='***',
passwd='***',
db='database1',
use_unicode=True,
charset="utf8")
cursor = connection.cursor()
query = """ select *
from example_table1
into outfile 'MYFOLDER'
fields terminated by ';'
enclosed by '"'
lines terminated by '';
"""
cursor.execute(query)
connection.commit()
cursor.close()
I get this error message:
Traceback (most recent call last):
File "mysql_export_to_csv.py", line 46, in <module>
cursor.execute(query)
File "/usr/lib/python2.7/dist-packages/MySQLdb/cursors.py", line 226, in execute

raise errorvalue
_mysql_exceptions.InternalError: (1, 'Can\'t create/write to file \'/usr/src/Python-2.7.13/output.csv\' (Errcode: 30 "Read-only file system")')
What is the problem in this code? Why I can't export it to .csv?
I suggest to try saving your in a directory where you surely have write permissions like /tmp/
Like this:
connection = MySQLdb.connect(host='localhost',
user='***',
passwd='***',
db='database1',
use_unicode=True,
charset="utf8")
cursor = connection.cursor()
query = """ select *
from example_table1
into outfile '/tmp/myfile.csv'
fields terminated by ';'
enclosed by '"'
lines terminated by '';
Below are the code that is not working
#!/usr/bin/python
import urllib
import datetime
import mysql.connector
data['price'] = 100
# Write to database
cnx = mysql.connector.connect(user='user', password='pw', database='db')
cursor = cnx.cursor()
query = ("INSERT INTO records(price) VALUES(%s) ")
cursor.execute(query, (data['price']))
cnx.commit()
cursor.close()
cnx.close()
MySQL has the corresponding table and column.
id (PRIMARY INT AUTO_INCREMENT)
price (FLOAT)
There is no connection problem.
It gives the following error. Any idea?

the MySQLCursor.execute() method takes a tuple (or a dict) as second (params) argument.
in your case: it should be (data['price'], ) (note the additional comma; without it the brackets have no effect) instead of (data['price']).
Let's try to find a solution:
Do not execute your query, instead mogrify and print it. For example:
query = ("INSERT INTO records(price) VALUES(%s) ")
query_to_be_executed = cursor.mogrify(query, (data['price']))
print(query_to_be_executed)
Next try to execute your printed query manually in bash or phpMyAdmin and fix it.
Finally use fixed query in your python code.
I am attempting to insert some sentiment analysis results (google cloud language API) into a mysql database. I am using the mysql connector.
import mysql.connector
from google.cloud import language
cnx = mysql.connector.connect(user='blahuser', password='Blahpw',
host='BlahIP',
database='FeedbackDB')
cursor = cnx.cursor(buffered=True)
CoreSQL = ("SELECT ResID, TextResp FROM Response")
cursor.execute(CoreSQL)
client = language.Client()
for row in cursor:
document = client.document_from_text(row[1])
sent_analysis = document.analyze_sentiment()
sentiment = sent_analysis.sentiment
annotations = document.annotate_text(include_sentiment=True, include_syntax=True, include_entities=True)
print(row[0], sentiment.score, sentiment.magnitude)
ResID_ =row[0]
PhraseSent_ = sentiment.score
PhraseMag_ = sentiment.magnitude
SQLInsertCmd = ("INSERT INTO PhraseAnalysis (ResID, PhraseSent, PhraseMag), VALUES (%s,%s,%s)");
cursor.execute(SQLInsertCmd, (ResID_, PhraseSent_,PhraseMag_))
cnx.commit()
cursor.close()
cnx.close()
The error I get indicates I have an issue with my INSERT statement :
python tm16.py
(1, -0.4, 2.2)

There are lots of INSERT examples online, but I haven't be able to resolve. New to coding- no doubt something simple. Can someone point out where I am going wrong?

You have an unnecessary comma after the end of the fields list.
I am trying to figure out why doesn't my test programme in python work.
I can access the database just fine from MySql Workbench, and I think I did everything right with the programming part, I also went to Administrative Tools and added my database to ODBC Database Sources, here is my test programme, if anyone can figure out what's wrong:
import pypyodbc
conn = pypyodbc.connect("DSN=database")
def func():
l = []
cur = conn.cursor()
try:
cur.execute("SELECT foo FROM table")
except pypyodbc.DatabaseError:
pass
conn.commit()
for i in cur:
l.append(i)
conn.close()
cur.close()
func()
The Error I'm getting is:
Traceback (most recent call last):
File "D:/path/test.py", line 21, in <module>

File "D:/path/test.py", line 14, in func

pypyodbc.DataError: ('22018', '[22018] [MySQL][ODBC 5.3(a) Driver][mysqld-5.5.5-10.0.17-MariaDB]')
Error 22018 is an "invalid character" error. One common cause is trying to use the ANSI ("(a)") version of MySQL Connector/ODBC to retrieve Unicode data. In that case the solution is to use the Unicode ("(w)") version of the driver instead.
I am trying to insert some data into a MySQL DB with Python and MySQLdb. When i do the following:
query = "INSERT INTO universitats (universitat) VALUES ('%s')" % (lloc)
cursor.execute(query)
db.commit()
I get this error:
Traceback (most recent call last):
File "read.py", line 39, in <module>
cursor.execute(query)
File "/usr/lib/python2.7/dist-packages/MySQLdb/cursors.py", line 174, in execute

raise errorclass, errorvalue
_mysql_exceptions.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Hospitalet de Llobregat')' at line 1")
What am I doing wrong?
This lines:
query = "INSERT INTO universitats (universitat) VALUES ('%s')" % (lloc)
cursor.execute(query)
should look like this
query = "INSERT INTO universitats (universitat) VALUES (%s)"
cursor.execute(query,(lloc,))
and then commit.
