Global Temp Table issue

I am attempting to create a global temp table to be used between two sessions being called from a webservice.

When I attempt to access the temp table from the second session it can not be found. The reason I am using a global temp table is because the initial session is created on a before event handler which calls the service and then from an after event handler.

I have checked that the table is still available after the initial session closes, and I am still able toe query the data.

Any help would be greatly appreciated!

public void SetUpdateHolds(string SOPnumber, int SOPType, string companyId, string compDatabaseName)
            {
                
                
                SqlConnection conn = new SqlConnection(connString.StrEPConnString);
                conn.Open();
                

                try
                    {


                        string sql = " USE [" + compDatabaseName + "]" +
                                     "CREATE TABLE ##HOLDS (HOLDID varchar (20)) ";
                                     
                        SqlCommand command = conn.CreateCommand();
                        command.CommandText = sql;
                        command.ExecuteNonQuery();

You need to call new on your new SQL commands.
Also, don't you get an Exception or an invalid state when the code hits the ExecuteReader followed by the ExecuteNonQuery?
