I'm trying to execute a sql query through powerpivot and I get the following error
"Unable to convert a value to the data type requested for table (massive hex string) column (name)"
SELECT [name], [table].[group],[table2].[group2] ,SUM([number]) AS number
FROM table LEFT JOIN [table2] ON table.[group ID] = [table2].id
GROUP BY [name],[table].[group],[table2].[group2]
Powerpivot's validator is happy with the query and the same query runs fine through sql management studio, any ideas how I can fix this?
