The computing power of SQL for mass structured data is complete, that is to say, it is impossible to find anything that SQL cannot compute. But its support layer is too low, which can lead to over-elaborate operation in practical application.One of the four aspects of this "over-elaboration" is "computation without substep", but before we comment on it, the article glosses over an important matter.
