So the conundrum continues.. The simple test case above now runs, but if I upsert a large number of new records (successfully) and then try to upsert a fewer number of new records to a different table, I get the same error.

If I run the same upserts again (which in the first case means there are no new records to add, because they were already added), the second upsert works correctly.

It feels as if the number of items added via an upsert >> the number of items I try to add in an upsert immediately after, I get the error.

Hmmm... just tried with installs from pip and the repo (v2.0.0 and v2.0.1) and I get the error each time (start of second run through the second loop).

Could it be sqlite3? I'm on 3.30.1.

UPDATE: just tried it on jupyter.org/try and I get the error there, too.

Odd.. I'm not able to replicate that error. Here's what I got:

I think I actually had several issues in play...

The missing key was one, but I think there is also an issue as per below.

For example, in the following:

```python def init_testdb(dbname='test.db'):

if os.path.exists(dbname):
    os.remove(dbname)

conn = sqlite3.connect(dbname)
db = Database(conn)

return conn, db

conn, db = init_testdb()

c = conn.cursor() c.executescript('CREATE TABLE "test1" ("Col1" TEXT, "Col2" TEXT, PRIMARY KEY ("Col1"));') c.executescript('CREATE TABLE "test2" ("Col1" TEXT, "Col2" TEXT, PRIMARY KEY ("Col1"));')

print('Test 1...') for i in range(3): db['test1'].upsert_all([{'Col1':'a', 'Col2':'x'},{'Col1':'b', 'Col2':'x'}], pk=('Col1')) db['test2'].upsert_all([{'Col1':'a', 'Col2':'x'},{'Col1':'b', 'Col2':'x'}], pk=('Col1'))

print('Test 2...') for i in range(3): db['test1'].upsert_all([{'Col1':'a', 'Col2':'x'},{'Col1':'b', 'Col2':'x'}], pk=('Col1')) db['test2'].upsert_all([{'Col1':'a', 'Col2':'x'},{'Col1':'b', 'Col2':'x'}, {'Col1':'c','Col2':'x'}], pk=('Col1')) print('Done...')

Test 1... Test 2... IndexError: list index out of range

IndexError: list index out of range ```

the first test works but the second fails. Is the length of the list of items being upserted leaking somewhere?

Released as 2.0.1 https://github.com/simonw/sqlite-utils/releases/tag/2.0.1

I think this is because you forgot to include a pk= argument. I'll change the code to throw a more useful error in this case.
