Received notification from DBMS server: {severity: WARNING} {code: Neo.ClientNotification.Statement.FeatureDeprecationWarning} {category: DEPRECATION} {title: This feature is deprecated and will be removed in future versions.} {description: The procedure has a deprecated field.

请问出现这类报错如何解决。

要解决由于在 Cypher 查询中使用 apoc.meta.graphSample 过程中的 config 字段而导致的弃用警告，您应该从查询中删除 config 字段。更新后的查询应如下所示：

schema_counts = self.structured_query(
    "CALL apoc.meta.graphSample() YIELD nodes, relationships "
    "RETURN nodes, [rel in relationships | {name:apoc.any.property"
    "(rel, 'type'), count: apoc.any.property(rel, 'count')}]"
    " AS relationships"
)

此修改删除了不再需要的 config 字段，应能解决弃用警告 ^[1]。

源代码和你给的代码是一致的，运行之后依旧出现同样的错误，请问还有其他的解决方法吗？

要解决这个弃用警告，您应该将 apoc.meta.graphSample 替换为 apoc.meta.subGraph。更新后的查询如下：

schema_counts = self.structured_query(
    "CALL apoc.meta.subGraph({}) YIELD nodes, relationships "
    "RETURN nodes, [rel in relationships | {name:apoc.any.property"
    "(rel, 'type'), count: apoc.any.property(rel, 'count')}]"
    " AS relationships"
)

这样应该可以消除弃用警告 ^[1]。
