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 ''__''']
...
