Need to use WITH (NOLOCK) with select queries

[mfatah14]

Hi

I'm using bltoolkit for my application and after deploying it on production environment it was very slow due to read with locking, I have no problem to read dirty data, so how to use WITH (NOLOCK) with my select queries

Thanks

See an example:

        using (DbManager db = new DbManager())
        {
            db.BeginTransaction(IsolationLevel.ReadUnCommitted);

            // ...

            db.CommitTransaction();
        }

I know that read uncommitted will work but I Use a generic method to get queryable from an entity and I don't know exactly when the query will be executed or else when I'm getting my result ( calling ToList() Method ) I must call commitTransaction after it

Any other solutions

Is it not possible to use IsolationLevel.ReadUnCommitted without creating a Transaction?
Or is it no problem if I create a Transaction for every read call?

[mfatah14]

that is what I'm saying, I will need to open transaction with any read operation which is not possible with linq deferred execution

Any solution

@mfatah14,
See this, it can work for you: #214 (comment)

Though initially I put a question there about query hints, the answers were still useful and allowed me to implement table hints, e.g. "with (nolock)".
