tuple_object:unpack()

object tuple_object¶

tuple_object:unpack([start-field-number[, end-field-number]])¶

If t is a tuple instance, t:unpack() will return all fields, t:unpack(1) will return all fields starting with field number 1, t:unpack(1,5) will return all fields between field number 1 and field number 5.

Return:	field(s) from the tuple.
Rtype:	lua-value(s)

In the following example, a tuple named t is created and then all its fields are selected, then the result is returned.

tarantool> t = box.tuple.new{'Fld#1', 'Fld#2', 'Fld#3', 'Fld#4', 'Fld#5'}
---
...
tarantool> t:unpack()
---
- Fld#1
- Fld#2
- Fld#3
- Fld#4
- Fld#5
