Review comment:
if the value was null and the field is not nullable, we would be setting
the wrong value, right? (e.g. [for numeric columns, it would be
0](https://docs.oracle.com/javase/7/docs/api/java/sql/ResultSet.html#getShort(int)))
- should we be erroring out? perhaps we should:
```
if (rs.wasNull()) {
rowBuilder.addValue(null);
} else {
rowBuilder.addValue(value);
}
```
what are your thoughts?
