Error Code Incorrect Syntax When Pivoting from SQL

Hi all,

 

I have the following error when I go to unpivot columns in power query. Everything works fine regarding access to the account and making other changes, it is only when I go to unpivot the columns that I get a problem - my current theory is because I'm trying to pivot 300+ columns. But rather than try a work around I just wanted to confirm before creating extra work (as I have to do this on a few tables). Thanks for any info. Cheers

    Hi NMOORE ,

    Based on the error message you've provided, it seems like the issue is related to the SQL syntax, specifically near the 'from' keyword and '$Pivot'. Try using some tools to check the queries sent to the data source for errors near those keywords.

    As you've suspected, pivoting a large number of columns (300+ in your case) can sometimes lead to issues. If possible, try to reduce the number of columns you're attempting to unpivot in a single operation to see if you can figure out the error.

      Hi Gao,

       

      Thanks for your reply.

       

      I assumed as much regarding the SQL and can look into that. The only thing is the SQL table is fine in Power query  until I go to pivot, and I don't think the word 'Pivot' is used building the table. I guess this would make the culprit the excessive columns I'm trying to Pivot, but I can't find anything regarding limitations and was hoping to understand this in its entirety before I carry on.

       

      Cheers

      With me it was too many columns I was trying to pivot, I cannot confirm 100% but it was the only thing that made sense. I seperated them, unpivoted then appended, all has worked fine since
