FULLSCAN cannot be used with the SAMPLE option. When omitted, SQL Server uses sampling to create the statistics, and determines the sample size that is required to create a high quality query plan.First, you express each deviation from the mean in absolute values by converting them into positive numbers (for example, -3 becomes 3). Then, you calculate the mean of these absolute deviations. Unlike the standard deviation, you don’t have to calculate squares or square roots of numbers for the MAD.Gathering table and column statistics, using the COMPUTE STATS statement, helps Impala automatically optimize the performance for join queries, without requiring changes to SQL query statements.
