用foreach创建节点间的关系

Question

我必须使用istat标签在节点和所有节点之间创建关系；因此尝试了以下查询：START MATCH (i:istat), c = node(21519) FOREACH(i|CREATE UNIQUE (c)-[r:CAN_SEE]->(i)；但是控制台给了我这个错误：

    SyntaxException: Invalid input 'u': expected whitespace, comment, NodeLabel, MapLiteral, a parameter, a relationship pattern, '.', '[', "=~", IN, IS, '*', '/', '%', '^', '+', '-', '<', '>', "<=", ">=", '=', "<>", "!=", AND, XOR, OR or '|' (line 1, column 101)
==> "start c =node(21519) match(i:istat) with collect(i) as istat_code,n foreach(i in istat_code: create unique (n)-[r:CAN_SEE]->(i))"
==>                                                                                                      ^

Answer 1

尝尝这个

START c=node(21519)
MATCH(i:istat) WITH c,collect(i) AS istat_code 
FOREACH(t in istat_code | CREATE UNIQUE (c)-[r:CAN_SEE]->(t))
