Format a field to Title Case when using Direct Query

Hello,
I need to set a field to Title Case, which is easily done in Transform Data > Transform Tab > Format > Capitalise Each Word
However I'm getting an error that this can't be done with Direct Query. I can't change this data to Import, it has to be Direct Query. Is there an alternative way in DAX (or however else) to set the field to Title Case?
Thank you

 
  • Hi Ry5 ,

     

    No, Direct Query mode does not support this complex query foldring. The only way to solve the problem is from your database side

     

    The power bi get data form SQL Database is using query foldring to change the query to sql statement and send it to SQLDB, then SQLDB return the data to power bi. 

    Query foldring only support simple transform data like sum(), rename().This is for better performance performance and unnecessary errors. For more details you can refer these links.

    In the datasource connection --> Advance options --> Specify the Select query. 

    Example : select upper(colname) Col1, lower(colname) Col2 from table1.

      This returns two columns - one with the field in all uppercase, the second with the field in all lowercase
      I need the field to be in Title Case, where every word has a capital first letter and the remaining are all lowercase
