Error using %s for String Formatting in MySQL Query with Python

this one helps. I'm not in python but%s is used for passing param so Try escaping the % using %%
code :
  from_unixtime(el.DeviceTimeStamp/1000, '%%Y-%%m-%%d %%H:%%i:%%s') as 'Entry_Timestamp'```
  from_unixtime(el.DeviceTimeStamp/1000, '%Y-%m-%d %H:%i:%%s') as 'Entry_Timestamp'```

Formatting MySQL query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server ver

will help you According to the error message, you have an extra single quote before the WHERE clause.
As a sidenote, DISTINCT keyword will be more likely to be useless because it will only work if all values in all columns are equal on both row otherwise the row is unique even if they have the same value.

Python character formatting with mySQL raw db query giving me problems

Hope that helps Don not use string interpolation for SQL queries, it's completely unsafe.
Instead, use query parameters:
code :
sql = """SELECT 
             * 
         FROM 
             db_email 
         WHERE
             user_id = %s AND 
             deleted = 0 AND 
             subject LIKE '%%%s%%'"""
cursor.execute(sql, (user_id, searchparams))
sql = """SELECT 
             * 
         FROM 
             db_email 
         WHERE
             user_id = %s AND 
             deleted = 0 AND 
             subject LIKE %s"""
cursor.execute(sql, (user_id, "%" + searchparams + "%"))

it fixes the issue When using MySQL Connector for Python, use %s as a placeholder for string values
code :
cursor.execute("INSERT INTO " + mysql_localhost_database +".hadith" +
                   " (hadith,translated_hadith,topic)" + " VALUES (%s, %s, %s)",
               (arabic_hadith, english_hadith, topic))

Python string formatting on MySQL query

this will help From the looks of your code, I'm gussing your basing it off of imploding a list for use in a python MySQLDB IN clause. Assuming that's the case, and format_strings is built similar to:
code :
format_strings = ','.join(['%s'] * len(cod_art_int))
query_params = list(cod_art_int)
query_params.append(int(shop))

query_sql = """
  SELECT cod_art, price_EU, price_third_country 
  FROM lt_gamma_articles
  WHERE cod_art IN ({cod_art_list}) AND cod_store = %s 
  ORDER BY cod_art, timestamp
""".format(cod_art_list=format_strings)

cursor.execute(query_sql, query_params)
cod_art_int = [10, 20, 30]
format_strings = ','.join(['%s'] * len(cod_art_int))
step_one = ['%s'] * len(cod_art_int)
# ['%s', '%s', '%s']

format_strings = ','.join(step_one)
# '%s,%s,%s'
query_sql = """
    SELECT cod_art, price_EU, price_third_country 
    FROM lt_gamma_articles
    WHERE cod_art IN ({cod_art_list}) AND cod_store = %s 
    ORDER BY cod_art, timestamp
""".format(cod_art_list=format_strings)
SELECT cod_art, price_EU, price_third_country 
FROM lt_gamma_articles
WHERE cod_art IN (%s,%s,%s) AND cod_store = %s 
ORDER BY cod_art, timestamp
query_params = list(cod_art_int)
# [10, 20, 30] 

query_params.append(int(shop))
# [10, 20, 30, 456] 
cursor.execute(query_sql, query_params)

Python's string formatting throws error when applied within mysql

Any of those help Better to let the MySQL Connector bind the variables, by using %s's. This avoids SQL injection. Here a working example.
code :
import MySQLdb

# set up db connection
dbApi = MySQLdb
connection = MySQLdb.connect(
    host    = <hostname>,
    user    = <databasename>,
    passwd  = password,
    db      = <dbname>,
    port    = 3306,
    charset = "utf8")
cursor = connection.cursor(dbApi.cursors.DictCursor)

# insert records
records = [['George', 'Ten', 'Good'],
           ['Ringo', 'Ten', 'Good'],
           ['Paul', 'Ten', 'Good'],
           ['John', 'Ten', 'Good']]
insert_sql = 'insert into webdata (name, bubble, review) values (%s, %s, %s)'

for record in records:
    cursor.execute(insert_sql, record)

# list record
sql = 'select * from webdata'
cursor.execute(sql)
data = cursor.fetchall()
print 'data:', data

connection.commit()
cursor.close()
