sequence_object:current()¶

Since version 2.4.1. Return the last retrieved value of the specified sequence or throw an error if no value has been generated yet (next() has not been called yet, or current() is called right after reset() is called).

Пример:

tarantool> sq = box.schema.sequence.create('test')
---
...
tarantool> sq:current()
---
- error: Sequence 'test' is not started
...
tarantool> sq:next()
---
- 1
...
tarantool> sq:current()
---
- 1
...
tarantool> sq:set(42)
---
...
tarantool> sq:current()
---
- 42
...
tarantool> sq:reset()
---
...
tarantool> sq:current()  -- error
---
- error: Sequence 'test' is not started
