MariaDB SQL syntax near error parenthesis ')' for python

Question

I am trying to insert some data into my MariaDB using python script. when I do the following in console it works perfectly.

INSERT INTO `Failure` (`faillure_id`, `testrun_id`, `failed_at`, `log_path`, `node`) 
         VALUES   (2, 1, 'STEP8:RUN:RC=1', '/var/fail_logs','NodeA')

shows me a query ok. and I can see the table being populated. no problem there.

However when I do the same SQL query using python I get some error. Here's my code

conn = MySQLdb.connect("localhost","user","","DB")
cursor = conn.cursor()

cursor.execute("""INSERT INTO `Failure` (`testrun_id`, `failed_at`, `log_path`, `node`) VALUES (%s, %s, %s, %s)""",(testrun_id, failed_at, log_path, node))
conn.commit()

this yields the following error

check the manual that corresponds to your MariaDB server version for the right syntax to use near '),

Can someone please help me understand where the error is coming from.

Answer 1

As a work-around I'm building the query string like this

sql_query = "INSERT INTO `Failure` (`testrun_id`, `failed_at`, `log_path`, `node`) VALUES " + "( '" + str(testrun_id) + "', '" + str(failed_at) + "', '"+ log_path + "', '" + node + "')"
cursor.execute(sql_query)

not very efficient but does the job for now.
