dictGetUInt8, dictGetUInt16, dictGetUInt32, dictGetUInt64
dictGetInt8, dictGetInt16, dictGetInt32, dictGetInt64
dictGetFloat32, dictGetFloat64
dictGetDate, dictGetDateTime
dictGetUUID
dictGetString
dictGetT('dict_name', 'attr_name', id)
- 使用’id’键获取dict_name字典中attr_name属性的值。
dict_name和attr_name是常量字符串。id必须是UInt64。 如果字典中没有id键，则返回字典描述中指定的默认值。
dictGetTOrDefault
dictGetTOrDefault('dict_name', 'attr_name', id, default)
与dictGetT函数相同，但默认值取自函数的最后一个参数。
dictIsIn
dictIsIn ('dict_name', child_id, ancestor_id)
- 对于’dict_name’分层字典，查找’child_id’键是否位于’ancestor_id’内（或匹配’ancestor_id’）。返回UInt8。
dictGetHierarchy
dictGetHierarchy('dict_name', id)
- 对于’dict_name’分层字典，返回从’id’开始并沿父元素链继续的字典键数组。返回Array（UInt64）
dictHas
dictHas('dict_name', id)
- 检查字典是否存在指定的
id。如果不存在，则返回0;如果存在，则返回1。
