OLE DB or ODBC error: [DataSource.Error] ODBC: ERROR [42601] SQL compilation error: ambiguous column
In this case the best (and preferred option) in my opition is to create a view in snowflake.
Inside the view rename the field. The connect PowerBi to View instead of Table
Do not rename the field directly in the table. I wouldnt recommend that
Community ChampionBest to send to us the query that you used.
This error "SQL compilation error: ambiguous column" is return in cases e.g. when you have a join of 2 tables and the same column appears in both of them. When you do a select statement and you dont specify the table this column belongs to then it throws an error.
You can specify the table through the alias or the table name itself
Here is the part of the query that is causing the trouble. Ran as is, it will error. I've noticed when I add qualifiers to the two "CREATED" columns in the WHERE clause at the very end, the query will work. Is there a way to tell Power BI to do this?

Hello jacob-dickey
Do you actually mean whether PowerBI can add the right aliases right next to field names?
This cannot be done by PowerBI.
To give you some context.
The query that you wrote will also through the same error message if you run it to any database client. It is database generated error and not PowerBI one. In other words the error says that you didnt write the query properly and you need to make the necessary amendments.
On your query you use 2 tables ITBL and OTBL. For all fields you have used an alias but not on the fields in the where statement. This is bad writing of a SQL Query.
Also Created field is one of the main fields in a database table. If you dont specify the table alias correctly it will return wrong data.
The solution in your case is to put an alias (ITBL or OTBL) in front of every field in the where statement.
I hope that helped
Correct, I agree that is the problem with the query. However, I did not write that query, Power BI DirectQuery did.
I found that query in my Snowflake query history after getting the error in Power BI.- themistoklis
If i remember correctly you can not write a custom query and send it through PowerBI to snowflake.
You can only connect directly to tables in Snowflake. Corrct me if im wrong.
My understanding is that you have multiple steps in Power Query editor and one of the steps joins 2 tables. Is this right?
If this is the case, i think the best way to overcome this issue is by adding one more step and delete the duplicate columns from the table you are not interested in. I hope tis makes sense??
