Write T-SQL code to provide all valid Sudoku possibilities for nXn matrix.

This post specially dedicated to Anjana Ramamoorthy from Microsoft.

Below is the procedure sc.cp_Create_MetrixPosibilities_nXn which will take matrix size as parameter and create the table dbo.MetrixPosibilities_nXn with all valid Sudoku possibilities.

Below are parameters for the procedure sc.cp_Create_MetrixPosibilities_nXn.

1. @p_MatrixSize
1. Size of matrix for which we want to create all the possibilities.

Suppose, we have 3X3 matrix for which I want to create all valid possibilities then we can execute procedure as below.

EXEC sc.cp_Create_MetrixPosibilities_nXn 3
Go
Select count(1) From dbo.MetrixPosibilities_3X3
--> 12

Here, we have 12 valid possibilities created as below in table dbo.MetrixPosibilities_3X3.

Below are the scripts to download.
