/*-----------------------------------------------------------------------------------------------------
Sometime we have requirment to Enable CDC on Table including all the columns OR
enable CDC on table with set of columns. The SP can perform both tasks depending
upon provided parameters.This Stored Procedure will be used when CDC is already not enabled on Table. If CDC
is enabled on Table , The SP will not perform any action.

How to Execute: EXEC usp_EnableCdcOnTableWithOrWithoutColumnList @pSchemaName,@pTableName,@pColumnList

Enable CDC on Table with All columns
Example :usp_EnableCdcOnTableWithOrWithoutColumnList 'SchemaName','TableName',NULL

Enable CDC on Table with Given columns
Example :usp_EnableCdcOnTableWithOrWithoutColumnList 'SchemaName','TableName','Col1,Col2'
