Careful with your SQL Server Max Memory settings

Quite often I see database administrators set SQL Server max server memory thinking everything related to SQL Server uses this shared memory pool. This is a mistake.

5 Ways to Examine Cardinality Metrics

In SQL Server the query optimizer uses a cardinality estimator to answer data SELECTIVITY questions like the ones below. The optimizer uses this cardinality data, which relies heavy on statistics to get the answers and calculate a cost estimate. It takes the #of Rows to Satisfy a Predicate/Total # of… Read more
