OLE DB or ODBC error DISP_E_TYPEMISMATCH

Hi All,

 

this error shows up when I try to refresh data.

 

The data source is a local csv :

Config: windows 10

 

thanks for helping 🙂

The type mismatch is probably happening because you're doing some conversion from the orginial data types - go into the query editor and remove any type conversions and see if that works.

Sorry, didn't mention that deleting only "changed type" wasn't enough.

 

I had to delete all steps to get the connection with the data back.

 

Anyway, I'll recreate the steps, but It's a bit of a pain if it happens again after many changes in the query editor. We'll see 🙂

 

Thanks!

Hi adrien - did you ever figure out why this was happening? And if there was a fix/work around? I'm having the same issue.

Hi Evan,

 

Yes it worked for me. I had to remove all the applied steps (5 or 6) until the step 'changed type' which seemed to cause the error.

 

Since I re-created all the steps, the error never showed up again, so worth trying it!
