USAGE First run this script is the database where you want to store this procedure Then you can run the stored procedure with the following statement:
EXEC sp_ObjectExplore 'database.schema.tablename'
You do not need to supply databasename and schema (example: dbo) when table is in same database as this procedure.
If you want additional metrics concerning the distribution of all numeric variables, execute with parameter @distribution='yes'. Example: EXEC sp_ObjectExplore 'database.schema.tablename' , @distribution='yes' If you are only interested in a subset of columns, you can specify them in the parameter @columns Columnnames must be separated by a comma. You can specify them either with or without brackets  Columnnames may not contain commas. Example: EXEC sp_ObjectExplore 'database.schema.tablename' , @distribution='yes' , @columns='column1, column2, etc'
