Reorganizing a columnstore index can require additional CPU resources to compress data. While the operation is running, performance can slow. However, once data is compressed, query performance improves. For syntax examples, see Examples - Columnstore reorganize. Notă Starting with SQL...
Here are some examples of filter predicates for the Production.BillOfMaterials table: WHERE StartDate > '20000101' AND EndDate <= '20000630' WHERE ComponentID IN (533, 324, 753) WHERE StartDate IN ('20000404', '20000905') AND EndDate IS NOT NULL For guidance on filtered indexes, see Cr...
In SQL, the INDEX constraint in a column makes it faster to retrieve data when querying that column. In this tutorial, you will learn about the SQL CREATE INDEX statement with the help of examples.
