OdbcConnections - more or less?

[200dogz]

Performance speaking, is it better to stick with one connection or use a different one for each task?

In my case I have something like:

 
string query = ...
OdbcDataReader reader = connectionA -> read query
 
while (reader.Read())
{
    ...
 
    query = ...
    OdbcDataReader reader2 = connectionB -> read query
 
    if (reader.Read())
    {
        ...
    }
}
 

Should I use the same connection for A and B or different, or should I create a new connection for B for each loop?

Thanks :) ,

Connect to database?

For me, I will use a single Connection object, for database connection may be limited. And I will join 2 tables as a view (provided logically possible), so I can use just one DataReader to get the job done.

Thanks for the suggestion :)

Limiting the connections to a database is always advisable. Because it increases the performance of the application thereby decreasing the database server load.
