It sounds like you should be creating a View in SQL Server, which contains all records for all cities.

Then, you can create queries from your application (C#) which filter the table based on a single, selected City.

SQL Server provides caching of queries, so you will see a performance lift if the same city is queried multiple times.

The combination of your View and your query are, in essence, the 'temporary table' you are looking for. Be careful not to confuse this with SQL Server temporary table s or CTE 's.
