I'm OK changing that - I very much doubt anyone is relying on this functionality.

So no need for a new option here - just fixing the bug is sensible.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1373224657,`sqlite-utils transform` should set empty strings to null when converting text columns to integer/float,

I think the implementation fix needs to go near here: https://github.com/simonw/sqlite-utils/blob/0b315d3fa83c1584eaeec32f24912898621e437a/sqlite_utils/db.py#L1770-L1775

The trick is going to be teaching that generated SQL to know which columns are `integer` or `float` and to convert `""""` to `null` as part of that operation.

We need to only apply that function to columns that we know to be of type integer or float though - text columns containing empty strings should not be rewritten to null.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1373224657,`sqlite-utils transform` should set empty strings to null when converting text columns to integer/float,
