Feature: SkipLimitAcceptanceTest
|
|
|
|
Background:
|
|
Given any graph
|
|
|
|
Scenario: SKIP with an expression that depends on variables should fail
|
|
When executing query:
|
|
"""
|
|
MATCH (n) RETURN n SKIP n.count
|
|
"""
|
|
Then a SyntaxError should be raised at compile time: NonConstantExpression
|
|
|
|
Scenario: LIMIT with an expression that depends on variables should fail
|
|
When executing query:
|
|
"""
|
|
MATCH (n) RETURN n LIMIT n.count
|
|
"""
|
|
Then a SyntaxError should be raised at compile time: NonConstantExpression
|
|
|
|
Scenario: SKIP with an expression that does not depend on variables
|
|
And having executed:
|
|
"""
|
|
UNWIND range(1, 10) AS i
|
|
CREATE ({nr: i})
|
|
"""
|
|
When executing query:
|
|
"""
|
|
MATCH (n)
|
|
WITH n SKIP toInteger(rand()*9)
|
|
WITH count(*) AS count
|
|
RETURN count > 0 AS nonEmpty
|
|
"""
|
|
Then the result should be:
|
|
| nonEmpty |
|
|
| true |
|
|
And no side effects
