SP To Determine Layout, Population And Sample Data In Table(s)

Hi! I am new to SQL Server... looking for some veteran assistance.

"Data Integrity Report"

I need a Stored Procedure that takes a table name as a parameter and returns a cursor suitable as a data source for a pre-built Report Services report (I guess Report Services would call the SP?).

The cursor/report needs to have the following columns:



Ordinal_Position (I.E. Column number)
Column_Name
Number Of Blank Rows (how many missing values for this column in this table)
Difference (Between total rowcount and population of this column)

Data_Type

Column_Length (either Character_Maximum_Length or the numeric widths rolled up with COALESCE?)
Sample Data (The contents of the "first" row in the table, based on a TOP(1) and ORDER BY xxx)
The report should look like this (for a table with 100 rows):

Col Num Col Name # Blanks Difference Data Type Col Length Sample Data
1 Name 12 88 varchar 30 Sally Smith
2 Address 34 66 varchar 45 123 Main St Apt 45
3 Acct_ID 0 100 varchar 4 AB12345

Using the "Information_Schema.Columns" I can get everything I need except for #3 (blanks count) and #7 (Sample data).

Is it possible to do this as 1 query, with a CTE or APPLY or something, or do I need to do a table variable based on the Information_Schema and then use dynamic SQL and row-by-row COUNT(*) for each column? And the same for the Sample Data.

Sorry for the long post, and thanks in advance!
