  • 0

I have the following scenario: there are a database that generates a new logTable every year. It started on 2001 and now has 11 tables. They all have the same structure, thus the same fields, indexes,pk’s, etc.

I have some classes called managers that – as the name says – manages every operation on this DB. For each different table i have a manager, except for this logTable which i have only one manager.

I’ve read a lot and tried different things like using ITable to get tables dynamically or an interface that all my tables implements. Unfortunately, i lose strong-typed properties and with that i can’t do any searches or updates or anything, since i can’t use logTable.Where(q=> q.ID == paramId).

Considering that those tables have the same structure, a query that searches logs from 2010 can be the exact one that searches logs from 2011 and on.

I’m only asking this because i wouldn’t like to rewrite the same code for each table, since they are equal on it’s structure.

EDIT

I’m using Linq to SQL as my ORM. And these tables uses all DB operations, not just select.

    As long as each of your queries return the same shape, you can use ExecuteQuery<Log>(“Select cols From LogTable” + instance). Just be aware that ExecuteQuery is one case where LINQ to SQL allows for SQL Injection. I discuss how to parameterize ExecuteQuery at http://www.thinqlinq.com/Post.aspx/Title/Does-LINQ-to-SQL-eliminate-the-possibility-of-SQL-Injection.
