Error Inserting records into mariadb table using Python : 1366 (22007): Incorrect integer value: '%s' for column

[#1]

I am inserting records in maria db table from a file using python. Population column in the file is empty. I want it to go as empty value in table as well. Population column in table is set as integer and can accept null value. I am trying the below code -

Table Definition -
CREATE TABLE `local_db`.`table_x` (
`Unique_code` varchar(50) NOT NULL,
`city` varchar(200) DEFAULT NULL,
`state` varchar(50) DEFAULT NULL,
`population` bigint(20) DEFAULT NULL,
`Govt` varchar(50) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

```
input_file = "input_file"
csv_data = csv.reader(open(input_file))
try:
connection = mysql.connector.connect(host='localhost',
database='local_db',
user='root',
password='root',
port = '3306')

cursor = connection.cursor()
for row in csv_data:
cursor.execute("""
INSERT INTO table_x(Unique_code,city,state,population,Govt)
VALUES("%s", "%s", "%s","%s", "%s")
ON DUPLICATE KEY UPDATE city = VALUES(city),state = VALUES(state), \
population = VALUES(population),Govt = VALUES(Govt)""")
connection.commit()
print(cursor.rowcount, "Record inserted successfully into table_x")
cursor.close()

except mysql.connector.Error as error:
print("Failed to insert record into table_x table {}".format(error))



finally:
if (connection.is_connected()):
connection.close()
print("MySQL connection is closed")
```

But I am getting below error -

Failed to insert record into table_x table 1366 (22007): Incorrect integer value: '%s' for column `local_db`.`table_x`.`population` at row 1
MySQL connection is closed

In other thread it was suggested to change
SET sql_mode = ""
But its not an option for me since I would be running it on organization server which I can not change for this only. Please suggest what code changes I can do here to handle this situation.

This message is labeled NiFi, so I assume you have NiFi available?

In that case, look at finding the right processor for the job, something like ExecuteSQL may be a good starting point.

If your question is purely about how to make python and mariaDB interact, this may not be the best place to ask it.
