Convert Column from Text to Number in Direct Query

Hi Experts! 

I am running into an issue around trying to convert a column that is connected via direct query from a database from "Text" to "Number" type. I know that the proper way to do this is to make the adjustment in the database itself however I was wondering if there was an alternate way to do this in the query editor without having to switch everything to an Import? 

 

Thanks

Hi @danb,

 

What if while connecting to a database using DirectQuery you will use NativeQuery, where you can do whatever you want?

See example with CAST(CONVERT) below:

@danb,

 

it acts as a SQL batch (syntax is unlimited). So if you enter a query as I mentioned then it will be send to the database (calculations done on db side) and a result will be returned to Power BI. Use just SELECT statement and you will be safe.

Hello there,

 

I have the same exact problem with the dataverse tables not with SQL. So is there a solution for dataverse too? I would like to change the data type from text to whole number or decimal, does not matter at all. the thing is i do not want to loose the direct query from db. 

 

thank you

Thank you for your reply. So with the Cast/Convert, does that make changes to the actual database or just modify the the data as it is queried into Power BI?

Hello there,

 

I am having the same issue but your solution didn't work....

 

CAST(KPR_ptpi_amount as int) as (KPRAmount),

 

The error i get is:

DataSource.Error: Microsoft SQL: Incorrect syntax near '('.
Details:
    DataSourceKind=SQL
    DataSourcePath=rsobdcgenf;credopsreports
    Message=Incorrect syntax near '('.
    Number=102
    Class=15

 

What could i be doing wrong ?

There should be no parantheses (brackets) around your "(KPRAmount)" I think...

 

3 years late, but I'm here to save you!

Perfect. Thank you!
