I'm trying to use LINQ to SQL to retrieve earnings data for a particular date range. Currently the table is set up as follows:

Comp    Eps    Year    Quarter
IBM     .5     2012    2
IBM     .65    2012    3
IBM     .60    2012    4
IBM     .5     2011    2
IBM     .7     2013    1
IBM     .8     2013    2

Except for Eps, all fields have a data type of string or char. Eps has a data type of double. Here's my code:

var myData = myTable
    .Where(t => t.Comp.Equals("IBM")
        &&
        Convert.Int32(string.Format("{0}{1}", t.Year, t.Quarter)) <= 20131);

I get the following error when I tried that code:

Method 'System.String Format(System.String, System.Object, System.Object)' has no supported translation to SQL

How can I select all Eps that has a year & quarter less than "20132" using a lambda expression?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
