neo4j - Neo4j 中的多行执行

Question

我正在尝试执行以下密码:

// Nodes created for Lessons, Submitter, Center and Topic
// Relations created 
// Uniqueness constraints.
CREATE CONSTRAINT ON (l:Lesson) ASSERT l.name IS UNIQUE;
// Load.
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS FROM
'file:///llis.csv' AS line
WITH line, SPLIT(line.LessonDate, '-') AS date
CREATE (lesson:Lesson { name: TOINT(line.`LessonId`) } )
SET lesson.year = TOINT(date[0]),
    lesson.month = TOINT(date[1]),
    lesson.day = TOINT(date[2]),
    lesson.title = (line.Title),
    lesson.abstract = (line.Abstract),
    lesson.lesson = (line.Lesson),
    lesson.org = (line.MissionDirectorate),
    lesson.safety = (line.SafetyIssue),
    lesson.url = (line.url)

但是，我无法在浏览器中执行此操作，因为它是分开的两行。查看错误:

节点 (562) 已经存在，标签 Lesson 和属性 name = 0

我知道我打算在 Neo4j-shell 中执行此操作。我已设法进入 Neo4j-shell，但我如何在那里运行这段代码？

将你的语法放在一个文件中，然后按如下方式运行它:

在 Windows 上

type yourfile.cypher | bin\cypher-shell.bat -u <user> -p <password>

在 Linux 上

cat yourfile.cypher | bin/cypher-shell -u <user> -p <password>

希望对您有所帮助， 汤姆
