IsAliased always null in GetSchemaTable

Question

GetSchemaTable() always returns IsAliased as null, and BaseColumnName is always the same as ColumnName, even though I have used an alias name to fetch column data from Stored Procedure.

SP:

SELECT u.Name AS [Display Name]  
  ,code AS [Display Code]
........

C#:

DbDataReader reader = null;
DataTable dt = reader.GetSchemaTable();
