Python how to know if a record inserted successfully or not

Question

I'm using Python MySQL Connector, I inserted a record into database, and it was successful. But in Python code, how can I know if it is inserted or not? My Table does not have a primary key.

def insert(params) :     db_connection = Model.get_db_connection()     cursor = db_connection.cursor()     try :         cursor.execute("""INSERT INTO `User`(`UID`, `IP`) VALUES(%s,%s);""", (params))         db_connection.commit()     except :         db_connection.rollback()     Model.close_db(db_connection)     return result 

Answer 1

You can use .rowcount attribute:

cursor.execute("""INSERT INTO `User`(`UID`, `IP`) VALUES(%s,%s);""", params) print("affected rows = {}".format(cursor.rowcount)) 

.rowcount This read-only attribute specifies the number of rows that the last .execute*() produced (for DQL statements like SELECT) or affected (for DML statements like UPDATE or INSERT). [9]
