```python
    column_name_to_id = {}

    def column_id(column):
        if column not in column_name_to_id:
            id = db[""columns""].lookup(
                {""namespace"": namespace_id, ""name"": column},
                foreign_keys=((""namespace"", ""namespaces"", ""id""),),
            )
            column_name_to_id[column] = id
        return column_name_to_id[column]
```
If you're going to be doing a large number of `table.lookup(...)` calls and you know that no other script will be modifying the database at the same time you can presumably get a big speedup using a Python in-memory cache - maybe even a LRU one to avoid memory bloat.",140912432,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/350/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,
