Columns designated as character via CAST(x AS VARCHAR) are still treated as numeric #25927

Open francisbarton opened 2 months ago

Type: Bug

The status bar at the bottom of the window shows the number of unique values for a column, when that column is a character type. When the column is numeric it shows a mean and a sum.

If I have a column of numeric values x and I would like ADS to treat it as character, if I do CAST(x AS VARCHAR) then select the column in the viewer, it still shows average and sum in the status bar. I would like it to treat the column as a character and show me the summary of how many unique values are in the column of data.
