**Returns:**
boolean - true if the data reader is closed; otherwise, false.
### nextResult() {#nextResult}
```
public abstract boolean nextResult()
```


Advances the data reader to the next result, when reading the results of batch SQL statements.

**Returns:**
boolean - true if there are more rows; otherwise, false.
### read() {#read}
