I've changed my test to account for this difference and the test has passed successfully. I will submit a PR.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1279863844, https://github.com/simonw/sqlite-utils/issues/449#issuecomment-1174027079,https://api.github.com/repos/simonw/sqlite-utils/issues/449,1174027079,IC_kwDOCGYnMM5F-jtH,1690072,2022-07-04T17:33:04Z,2022-07-04T17:48:43Z,CONTRIBUTOR,"I've written the code and test. Would you be able to advise how to compare table columns in a pytest function properly? Experiencing a challenge when comparing columns. Test: ```python def test_duplicate(fresh_db): table = fresh_db.create_table( ""table1"", { ""text_col"": str, ""float_col"": float, ""int_col"": int, ""bool_col"": bool, ""bytes_col"": bytes, ""datetime_col"": datetime.datetime, }, ) dt = datetime.datetime.now() b = bytes('hello world', 'utf-8') data = {""text_col"": ""Cleo"", ""float_col"": 3.14, ""int_col"": -2, ""bool_col"": True, ""bytes_col"": b, ""datetime_col"": str(dt)} table1 = fresh_db[""table1""] row_id = table1.insert(data).last_rowid table1.duplicate('table2') table2 = fresh_db[""table2""] assert data == table2.get(row_id) assert table1.columns == table2.columns # FAILS HERE ``` Result: ![Screenshot 2022-07-05 at 1 31 55 AM](https://user-images.githubusercontent.com/1690072/177198814-daac48c9-5746-49d0-a14a-14fe181c5a2f.png) Failure is due to column types being named differently -- e.g. 'FLOAT' vs 'REAL', 'INTEGER' vs 'INT'. How should I go about comparing columns while accounting for equivalent types? Or did I miss out something in my duplication code correctly? Here's how I did it: in `db.py`, I've added the following code: ```python class Table(Queryable): [...] def duplicate( self, name_new: str ) -> ""Table"": """""" Duplicate this table in this database. :param name_new: Name of new table. """""" assert self.exists() with self.db.conn: sql = ""CREATE TABLE [{new_table}] AS SELECT * FROM [{table}];"".format( new_table = name_new, table = self.name, ) self.db.execute(sql) return self.db[name_new] ```","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1279863844,
