Problem pulling data out of MySQL in Power Query

Hey there.

 

I've been trying to pull data out of a MySQL server all day long but did not manage to. What I got so far is a two-column wide table that contains the ticket Id and the values of the ticket on a string (it actually is a JSON file that, at first, has not yet been converted into a table, so it is stored into a string as shown in the following image).

The query is quite simple, just as follows:

= MySQL.Database("ServerName", "DataBaseName", [ReturnSingleDatabase=true, Query="SELECT * FROM DataBaseName.json#(lf)WHERE ID<>""temp"""])

 

So far so good, but when I try to import this table into my model the following error pops up:

As far as I know, the problem lies on these null values, but even when I replace both on the query and on Power Query I get the above error

When I tried using REPLACE on my query, a different error appears:

SELECT REPLACE(t.json, 'null', 0)
FROM DataBaseName.json t

The previous query actually replaces the null values into 0, however not even that works out at the end of the day.

 

Important: I'm using the last-available version of MySQL connector (today is 21-June-2023).

 

Any thoughts?

 

Thanks in advance.

@Pedro503 , You can bring in Json in Power Bi and can split that column here in power bi

In select please check the exact function you want to use, in case you are using custom SQL

Thanks for your response, @amitchandak .

I watched your video but I don't think it fits in my problem. Basically in my case I pull the data from a MySQL server, and from there each row has a JSON alike format (in each row there's a string from which I can extract the data from).

However, it's also possible that I did not understand what you meant in your message. In what part should I select the MySQL to bring these JSON files?

Once again, thanks for your response.
