【问题描述】：

如何从graphQL和SQLAlchemy获取编译后的原始sql命令？我做了搜索，但没有运气:(

schema.py

class RecordType(SQLAlchemyObjectType):

    class Meta:
        model = Record
        interfaces = (graphene.relay.Node, )

class Query(graphene.ObjectType):

    node = graphene.relay.Node.Field()
    record = graphene.Field(RecordType, id=graphene.Int())

    def resolve_record(self, info, **args):
        id = args.get('id')
        return RecordType.get_query(info).get(id)

schema = graphene.Schema(query=Query, types=[RecordType])

【参考方案1】：

嗯，我刚刚找到了方法，参考来自https://***.com/a/36141722/9041712

query = RecordType.get_query(info)
print(query.statement.compile(compile_kwargs="literal_binds": True))
