选择到临时表后出现错误“无效的对象名称”

Question

I'm porting a working code to Microsoft Sql Server 2016 from a different dbms. The sql looks like

SELECT many_fields INTO #this_repository FROM complex_join WHERE parametric_cond

I open the connection

OdbcCommand server_cmd = new OdbcCommand(SQL_extractor_server, DbConnection);
OdbcParameter refresh_from_par = new OdbcParameter("@refresh_from",refresh_from);
OdbcParameter refresh_to_par = new OdbcParameter("@refresh_to",refresh_to);
server_cmd.Parameters.Add(refresh_from_par);
server_cmd.Parameters.Add(refresh_to_par);
server_cmd.ExecuteNonQuery();
server_cmd.Dispose();

and then execute some commands always inside that connection.

OdbcCommand tot_rows_cmd = new OdbcCommand("SELECT COUNT(*) AS 'tot_rows' FROM #this_repository",DbConnection);
tot_rows = (int)tot_rows_cmd.ExecuteScalar();
tot_rows_cmd.Dispose();

Can you explain the error or suggest where to look at? Thank you!

Further attempts

1. I've moved the code and the connection string from System.Data.Odbc to System.Data.SqlClient
2. I've added Pooling=false; to the connection string
3. I've inserted other code (just a SELECT @@spid from an ExecuteScalar ) to double check that the spid is always the same
4. I've debugged the return code ( int ) of the first ExecuteNonQuery and it is 0
5. I've executed the SQL from SqlDbx - one after the other - and it does work as expected
6. Tried from C# code with only one SqlCommand and two statements separated by ; : that also does work but it is not what I'm trying to accomplish

Unfortunately no luck till now!

Answer 1

It looks like a bug in ADO.NET

This answer clearly explains which is the root cause (and incidentally why it works in a Sql client):

I've tried by hard coding the parameters in the SQL and the issue doesn't show up.
