Suppose you're building an application where certain database fields can be null. How would you handle such scenarios using the database/sql package in Go?
- Convert null fields to a default value during scanning to avoid handling nulls.
- Ignore nullable fields during scanning. Treat them as empty values.
- Use custom scanning functions to handle null values explicitly.
- Use the Scan method to scan nullable fields into sql.Null types. Check if the valid flag is true to determine if the field is null or not.
When dealing with nullable fields in Go's database/sql package, you should use the Scan method to scan nullable fields into sql.Null types. You can then check if the valid flag is true to determine if the field is null or not. This ensures proper handling of null values.
