Question

Im trying to concatenate a dynamic insert statement ( over 100 inserts ) and instead executing one by one, i want to concatenate all of the statements into only one variable.

Following, a basic exemple:

insert_ = " insert into table ( field,zone) values ('a','b'); "
insert_b = " insert into table ( field,zone) values ('c','d'); "
insert_c = " insert into table ( field,zone) values ('e','f'); "

list = []
list.append(insert_)
list.append(insert_b)
list.append(insert_c)
print list

Current output:

[" insert into table ( field,zone) values ('a','b'); ", " insert into table ( field,zone) values ('c','d'); ", " insert into table ( field,zone) values ('e','f'); "]

Desired output:

insert into table ( field,zone) values ('a','b'); insert into table ( field,zone) values ('c','d');  insert into table ( field,zone) values ('e','f');

Thanks for reading.

Answer 1

c = db.cursor()
values_to_insert = [("a","b"),("c","d"),...]
c.execute_many("INSERT INTO table (val1,val2) VALUES (?,?)",values_to_insert  )

this is what execute_many is for …
