Transact SQL :: Select And Update Query In Same Stored Procedure

I have a stored procedure in which I'll select some rows based on a condition and I need to update the status of those rows within the same stored procedure.For e.g.

Create Procedure [dbo].[myProcedure]  As    BEGIN    BEGIN TRAN T1    SET NOCOUNT ON    SELECT TOP 5 * INTO #TempTable FROM myTable WHERE ENABLED = 1 AND FetchDate<=GetDate();    UPDATE myTable SET [Status] = 'Locked' From myTable Inner Join on #TempTable myTable.id = #TempTable.id;    SELECT * FROM #TempTable;    DROP Table #TempTable;    COMMIT TRAN T1    END

The Stored Procedure works fine when I debug in SQL. I'm accessing the StoredProcedure through C# like this.

private ProcessData[] ReadFromDb(string StoredProcedure, SqlConnection Connection) {                List<ProcessData> Data = new List<ProcessData>();  SqlCommand Command = new SqlCommand(StoredProcedure, Connection);  Command.CommandType = System.Data.CommandType.StoredProcedure;    try                {                    Command.CommandTimeout = CONNECTION_TIMEOUT;   

[code]....

The problem is I'm getting the required rows in C# but the update query in stored procedure is not working.
