## Synopsis

Use the `lastval()` function to return the value returned from the last call to `nextval()`, for any sequence, in the current session.

## Semantics

- An error is raised if `nextval()` has not been called in the current session.

## Examples

Create two sequences and call `nextval()` for each of them.

```plpgsql
yugabyte=# CREATE SEQUENCE s1;
```

```output
CREATE SEQUENCE
```

```plpgsql
yugabyte=# CREATE SEQUENCE s2 START -100 MINVALUE -100;
```

```output
CREATE SEQUENCE
```

```plpgsql
yugabyte=# SELECT nextval('s1');
```

```output
 nextval
---------
       1
(1 row)
```

```plpgsql
yugabyte=# SELECT nextval('s2');
```

```output
 nextval
---------
    -100
(1 row)
```

Call `lastval()`.

```plpgsql
yugabyte=# SELECT lastval()
```

```output
 lastval
---------
    -100
(1 row)

```
