C# - Select DataTable (only Some Values) From _GetDisplayData And GROUP Data By Days Where Group Rules Is Different For Different Columns

Stack-Overflow :3 I've got a kind of hard-case question.

So I'll try clearly explain my idea with my poor english :/ need select to DataTable SOME values from ???_**GetDisplayData **procedure for each day of previos month (GROUP IT) where group rules for different columns is different


I need to select some values in stored procedure from other stored procedure like this :

SELECT X FROM Y_Procedure(@ProcedureParameters)Also I need to select from dynamic SQL Procedure like

Y_Procedure=@Y+'_Procedure'
SELECT X FROM Y_Procedure(@ProcedureParameters)


Also I need to load it to DataTable :-/INSERT INTO @Report (CellHorizontal, CellVertical, CellValue) --to TABLE
SELECT Date,X2,X3 FROM Y_GetDisplayData(@Param)

SET NOCOUNT OFF;
SELECT *
FROM @Report

GetDisplayData works as select with parameters and that doesn't returns SQL DataTable
And there is no way to recode GetDisplayData's procedures, it's just constant procedures for me.Finally I need to Group nodes from this table

INSERT INTO @Report (CellHorizontal, CellVertical, CellValue)
SELECT T1.Date,
IF ((Select grouptype...)=1) T1.X2 + T2.X2
ELSE IF ((Select grouptype...)=2) AVG(T1.X2,T2.X2),
IF ((Select grouptype...)=1) T1.X3 + T2.X3
ELSE IF ((Select grouptype...)=2) AVG(T1.X3,T2.X3),
(SELECT T2.Date,X2,X3 FROM Y_GetDisplayData(@Param) T2
WHERE T2.Date>T1.Date AND T2.Date>=T1.Date)
FROM Y_GetDisplayData(@Param) T1
GROUP BY EVERY DAY ???--and here is epic fail


I can make all stuff on asp server :And C# allows me to use something like SelectCommand = IzmProc + "_GetDisplayData"; And then I will work (select special data) with DataTables on ASP.NET Server but it's better to make all on SQL ... But looking like it's just unrealizable on SQL >_<

I gonna think about C# realization,but my code is very weird , got errors and doesn't works >_<

public static DataTable GetReport(string Param)
{
System.Configuration.ConnectionStringSettings connSetting = ConfigurationManager.ConnectionStrings["FlowServerConnectionString"]; [code].....
