Closes #488. When
.transform(types={col: int})or{col: float}converts a TEXT column to INTEGER/REAL, empty-string values in the source rows are now written as NULL viaNULLIF(col, '')in the copy SQL, matching the design noted in the issue. Text columns are unaffected.📚 Documentation preview 📚: https://sqlite-utils--746.org.readthedocs.build/en/746/
