box.space._ck_constraint

box.space._ck_constraint

_ck_constraint is a system space where check constraints are stored.

Tuples in this space contain the following fields:

the numeric id of the space («space_id»),
the name,
whether the check is deferred («is_deferred»),
the language of the expression, such as „SQL“,
the expression («code»)

Example:

tarantool> box.space._ck_constraint:select()
---
- - [527, 'c1', false, 'SQL', '"f2" > ''A''']
  - [527, 'c2', false, 'SQL', '"f2" == UPPER("f3") AND NOT "f2" LIKE ''__''']
...
