Question

Just wondering what the best (fastest execution time) method for translating the following SQL to LINQ to SQL is?

IF EXISTS (SELECT TOP 1 * FROM HealthIndicators WHERE LogDate = getdate())
     UPDATE HealthIndicators SET Timeouts = 32
ELSE INSERT INTO HealthIndicators (Timeouts, 32)

I apologise if this is a repost but I haven’t been able to find an answer on the subject (I’m new, please be nice!)

Answer 1

var d = DateTime.Today; // or .Now
if (db.HealthIndicators.FirstOrDefault(h => h.LogDate == d) != null)
// or Any(h => h.LogDate == d)
{
    // update
}
else
{
    // insert
}
