Solutions

1. Check the value type is assignable to the field type or convertible via reflection.
2. Implement sql.Scanner/driver.Valuer on the field type for custom conversions.
3. Ensure the field is exported and addressable (destination passed as pointer).

Example fix

Match the assigned value's type to the field type or implement sql.Scanner/driver.Valuer on the field type.
