# unchecked-rows-error

**Default severity:** `error`

`Rows.Next` returns false both when iteration finishes successfully and when an
iteration error occurs. Check `Rows.Err` after the loop so driver, network, and
decoding failures are not silently treated as successful completion.

## Bad

```go
for rows.Next() { scan(rows) }
```

## Good

```go
for rows.Next() { scan(rows) }; if err := rows.Err(); err != nil { return err }
```
