cypher 資料庫的基礎使用

// 1.查詢
match (i:INCUBATOR) RETURN i;

// 2.查關系、查聯系
match (a:AREA)-[:BELONG]->(c:CITY {id:'成都市'}) return a,n;

match (u:USER {phone:'15882267723'})-[:WORK]->(p:SUBJECT)-[:PROVIDE]->(s:SERVICE) return u,p,s;

match (s:SUBJECT)-[r:INCUBATE]-(i:INCUBATOR) return r,s,i;

match (i:INCUBATOR {uid:'4dwroM9iuvcw7caDPhThz2'})-[:INCUBATE]->(p:SUBJECT)-[:PROVIDE]->(s:SERVICE) return s;

// 3.根據條件查詢
match (i:SUBJECT {status:0}) return i;

// 4.建立
create (i:INCUBATOR {name:'今天天氣好晴朗',status:2})

// 5.删除、據條件删除
match (i:INCUBATOR {name:'今天天氣好晴朗'}) detach delete i  //detach 若節點之間有聯系，加上detach則可以把聯系一起删掉

match (u:USER) where u.phone <> '15880172182' detach delete u
