MapperKernelMergeSort Method

Merge two sort clauses. SQL-Server will error if the same column is used more than once in an ORDER BY clause. If that happens on a saved sort there's no way to recover without clearing user preferences. This method will throw out any repeated columns.

protected string MergeSort(
	string clause1,
	string clause2
)

Protected Function MergeSort ( 
	clause1 As String,
	clause2 As String
) As String
