[英]how to get all database names in neo4j using python?
from neo4j import GraphDatabase
driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "password"))
with driver.session() as session:
result = session.run("SHOW DATABASES")
print(result)
the result is <neo4j.work.result.Result object at 0x0000028F2BB30208>结果是 <neo4j.work.result.Result object at 0x0000028F2BB30208>
How to get database names?如何获取数据库名称?
Add this code, this works for me添加此代码,这对我有用
databasesNames = list()
queryDatabases="SHOW DATABASES;"
try:
driver=GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "password"))
session=driver.session(database='system')
result = session.run(queryDatabases)
for record in result:
databasesNames.append(record["name"])
exit
except Exception as e:
print("Connection to neo4j failed: ", e)
print(databasesNames)
This will show you only the DATABASES names in cypher-shell:这将只显示 cypher-shell 中的 DATABASES 名称:
SHOW DATABASES yield name;
Example from python:来自 python 的示例:
test.py测试.py
from neo4j import GraphDatabase
driver = GraphDatabase.driver("bolt://localhost:7687", auth=("neo4j", "password"))
with driver.session() as session:
result = session.run("SHOW DATABASES yield name;")
for line in result:
print(line['name'])
When executed:执行时:
python test.py
