Usage Examples

In the predicate string parameter, we have to use the parameter $curr to check the current element.

Given the following dataset:

UNWIND [{date: datetime('1999'), other: 5}
    {date: datetime('2000'), other: 10},
    {date: datetime('2000'), other: 15} ] AS prop
CREATE (n:Date) SET n = prop;

we can execute:

MATCH (n:Date)
RETURN apoc.agg.row(n, '$curr.date <> datetime("1999") AND $curr.other > 11 ') AS row
