    I think we've found a bug in Data Access Free Edition Q3 2014 SP1, that wasn't there before.

    This example code:
    var row = entities.Table.Single(x => x.id == id && x.Active);

    Generates SQL of the form:
    SELECT ...
    FROM Table
    WHERE id = <value>
    thus ignoring the "Active" parameter.

    Changing the code to:
    var row = entities.Table.Where(x => x.Active).Single(x => x.id == id);
    Produces the expected query (adds an "AND" clause checking Active).

    Hello Matej,

    you are right, this is a glitch: when you use (x.Id == id && x.Active == true), the translation is correct. The failure comes from our internal GetObjectByKey detection that is is in place, but which fails to handle this non-compared boolean expression.

    Thank you very much for reporting this issue, I've just fixed this and the next build will contain the needed bits.
