I am using an oracle native connection from Power BI Desktop. However as the data load speed is very less i found out that OLE DB connection will be faster.
However when i try to use OLE DB connection with the same Oracle credentials , I am getting the error as
"An entry with the same key already exists".
I have no clue what the error is.
Can you please guide ?
Solved! Go to Solution.
i couldnt resolve the issue but i added a select query with required columns and the table in the advanced section. That gave me my data.. However i still say the issue persists because i think only some versions of Power BI is giving that error.
Hi @darshaningale ,
Are there some columns with the same field name in your data table?
