         table.update_item(                         Key=_filter,                         UpdateExpression='set type = :g',                         ExpressionAttributeValues={                             ':g': '111'                         }                     ) 
botocore.exceptions.ClientError: An error occurred (ValidationException) when calling the UpdateItem operation: Invalid UpdateExpression: Attribute name is a reserved keyword; reserved keyword: type
  • type 是保留关键词
  • 也没有象 mysql 加“的语法
