Question

Suppose I have one string list may have duplicated items:

A
B
C
A
A
C
D
E
F
F

I want to make a list can assign an unique index for each item, looks like:

1   A
2   B
3   C
4   D
5   E
6   F

now I created sqlite3 database with below SQL statement:

CREATE TABLE aa ( myid INTEGER PRIMARY KEY AUTOINCREMENT,
                  name STRING, 
                  UNIQUE (myid) ON CONFLICT FAIL,
                  UNIQUE (name) ON CONFLICT FAIL);

The plan is insert each row into the database in python.

My question is how to handle the error when conflict do happened when insert in python module sqlite3?
For example: the program will printing a warning message which item is conflicted and continue next insert action when inserting in python?

Thanks

Why not try it out and check which Exception is raised? That’s not too hard I think, but…

try:
    conn.excecute('...')
except IntegrityError:
    pass
