SQL Server count number of distinct values in each column of a table

Question

I have a table with ~150 columns. I\'d like to find the count(distinct(colName)) for each column but am wondering if there\'s a way to do so without actually t

You can do this:

DECLARE @query varchar(max)
    SELECT @query = 
    'SELECT ' + SUBSTRING((SELECT ',' +'COUNT(DISTINCT(' + column_name + ')) 
             As ' + column_name + ' '  
             FROM information_schema.columns
             WHERE 
             table_name = 'table_name'
             for xml path('')),2,200000)  +  'FROM table_name'

PRINT(@query)
