I am inserting data via a store procedure and I am trying to get the last id inserted. Data is being inserted. But when I try to return the last ID I get none or 0. I set the id field manually because of data replication. Not sure what I am missing.
query='database.insert_data'
params ='Josh'
last_id = mysql_conn.insert_proc(query, params)
print(last_id.fetchone())
prints none
class to insert data
def insert_proc(self,query,params):
self.curr.callproc(query, params)
self.conn.commit()
return self.curr
stored procedure
CREATE DEFINER=`me`@`localhost` PROCEDURE `insert_data`(v_name varchar(10))
SET @max_id = (select max(id)+1 from table);
insert into table (id,name)values(@max_id,v_name);
select @max_id;
I'm not very familiar with Python but according to the MySQL documentation here:
Result sets produced by the stored procedure are automatically fetched and stored as MySQLCursorBuffered instances. For more information about using these result sets, see stored_results().
"see stored_results()" leads to code examples featuring iteration over cursor.stored_results()
.
