    What would you change and why?

    • This topic was modified 11 months, 1 week ago by  yrstruly.
  • That's a huge chunk of code and, in my opinion, asking such general questions is the sort of thing you'd employ a paid consultant to help with.

    If you take the time to ask specific and bite-sized questions which demonstrate that you've at least tried to do some of the work yourself, rather than simply invoking AI and throwing out the results for comments, I'm sure that you'll get better results.

    The absence of evidence is not evidence of absence

    The absence of consumable DDL, sample data and desired results is, however, evidence of the absence of my response
    - Phil Parkin

  • Have you checked it returns the same results?

  • The code was not created by me. I am just investing some one else's code, this person is leaving us soon. I just want to make sure that the code does not have to be this difficult.

    Yes, but AI sometimes makes mistakes. I'm just asking because you need to make sure that the rewritten SQL is functionally the same as the original SQL.

  • To add to what Jonathan said - do you understand the code? If person A is supporting it now and understands the code and they are leaving and you are picking up support of it, can you support it? If end users report that it is missing some data, can you modify it to add the missing data? If it is giving duplicate results, can you correct that? Even just running the code and getting the same results isn't always enough - it could be there are edge cases covered in the original code that are missed by the AI version.

    It is one thing to rewrite it so it is easier for you to understand and to actually understand the code. My first step when looking at code that is long and wide is to run a SQL formatter on it (there are plenty out there, but I am a fan of SQL Prompt by RedGate for a paid option and Poor man's T-SQL formatter for a free one). Tweak the settings until the formatter is giving you output in a format you like and is easy for you to read and understand then learn and understand the code before you throw AI or any code altering tools at the code because YOU are being paid to support the code, not the AI. The AI may give you the same results today, but what happens when code changes are required?

    The above is all just my opinion on what you should do. 
    As with all advice you find on a random internet forum - you shouldn't blindly follow it.  Always test on a test server to see if there is negative side effects before making changes to live!
    I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.

  • I have a suggestion... how about having this "developer" document what each section of the code is actually doing in a business sense.  It needs a proper flower box to explain its purpose and possible usage example and the code itself needs an explanation as to the business purpose for each Select and, perhaps, what the reason for the CASE operators are for.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.

  • I agree with Jeff - if the code is complex or confusing, it should have comments around those bits explaining the logic. Now, if the code is confusing to someone outside the business, that is a different thing. For example, if I was working in Finance and I was doing some standard tax calculations (for example) on a column in the view, I wouldn't bother to document it because they are standard for my industry and anyone taking over my work should understand this. In your scenario, the cost element and structure don't mean anything to me (why is it called "Variable 3rdP Cycle1"? why "Cycle1"? are there multiple cycles and you only care about the first? What is 3rdP? are there multiple P's? What are P's?), but to you, you could see that and go "ah, that is for when the 3rd person starts cycle 1". Same thing with PB1.

    Curiosity got the better of me and I decided to look at the nested CASE statement that revolves around "ZA"'s and noticed that this (original code):

    CASE 

    WHEN MAN_ADJ_ALL.[Cost Element] LIKE 'Variable 3rdP Cycle1' AND MAN_ADJ_ALL.[Structure] LIKE 'PB1' THEN

    CASE

    WHEN MAN_ADJ_3RDPARTY.[Plant] LIKE 'ZA03' AND MAN_ADJ_3RDPARTY.[Business Process Activity] LIKE 'Handling'
    THEN MAN_ADJ_3RDPARTY.Amount * MAN_ADJ_3RDPARTY.[Weighting]

    WHEN MAN_ADJ_3RDPARTY.[Plant] LIKE 'ZA03' AND MAN_ADJ_3RDPARTY.[Business Process Activity] LIKE 'Repair'
    THEN MAN_ADJ_3RDPARTY.Amount * MAN_ADJ_3RDPARTY.[Weighting]

    WHEN MAN_ADJ_3RDPARTY.[Plant] LIKE 'ZA01' AND MAN_ADJ_3RDPARTY.[Business Process Activity] LIKE 'Repair'
    THEN MAN_ADJ_ALL.[Value Adjustment] - MAN_ADJ_3RDPARTY.Amount

    END
    ELSE

    MAN_ADJ_ALL.[Value Adjustment]

    END AS [Value]

    appears to be shrunk down to this by the "AI":

    CASE 
    WHEN MAN_ADJ_ALL.[Cost Element] = 'Variable 3rdP Cycle1' AND MAN_ADJ_ALL.[Structure] = 'PB1' THEN
    CASE
    WHEN MAN_ADJ_3RDPARTY.[Plant] = 'ZA03' THEN MAN_ADJ_3RDPARTY.Amount * MAN_ADJ_3RDPARTY.[Weighting]
    WHEN MAN_ADJ_3RDPARTY.[Plant] = 'ZA01' THEN MAN_ADJ_ALL.[Value Adjustment] - MAN_ADJ_3RDPARTY.Amount
    ELSE MAN_ADJ_ALL.[Value Adjustment]
    END
    ELSE
    MAN_ADJ_ALL.[Value Adjustment]
    END AS [Value]

    and while I agree that the "AI" version is easier to read, you will notice that the check around the plant being ZA03 in the original also requires the business process activity to be handling or repair as the calculation is the same for those 2 values. For the check on ZA01 you also require that the business process activity to be repair. The AI version doesn't do these checks. It could be that the checks are redundant, but can you say with 100% certainty that ZA01 will NEVER have "handling" as the business process activity or that ZA03 will NEVER have a value other than handling or repair as the business process activity? I cannot say that for certain as I don't know your data or processes, BUT if it can, then the AI code will definitely give you bad data for those rows. JUST from that one bit being potentially wrong, I would call the entire AI version suspect and likely to be wrong in other places.

    That being said, I don't see why the original developer used "like" for all those comparisons as they have no wildcard characters in the comparison... the AI is correct that it makes the code look cleaner to have "=" instead of "like". Now, that being said, there MAY be a reason why the original developer used "like" instead of "=" when doing the comparison (they are functionally equivalent when no wildcard is provided, but do not perform the same), but without talking to the original developer, I would be tempted to convert all the likes I could to = and do a performance comparison.

    TL;DR version - AI appears to have made some mistakes. I found one with a VERY quick look over the code. I wasn't even looking for anything overly specific, just sections in the AI code that looked to be overly simplified. This leads me to suspect that the AI code is flawed and shouldn't be trusted to give the same result.

    The above is all just my opinion on what you should do.
