Tuotekuvaus

Tällä kurssilla tutustutaan ”hands on” SQL Server 2016 -tietokantapalvelimen periaatteisiin ja käyttöön Transact-SQL-kyselykieltä (TSQL) käyttäen. Kurssilla opitaan hakemaan, lisäämään, poistamaan ja käsittelemään tietokantaan tallennettua sisältöä. Hakutuloksia rajataan ja käsitellään TSQL-kyselykielen edistyneempiä ominaisuuksia käyttäen: Ehdolliset hakulauseet, haun tulosten järjestely, haut useista tauluista, sisäänrakennettujen funktioiden käyttö ja joukko-operaattorien käyttö.

KENELLE

Kurssi on tarkoitettu tietokannoista kiinnostuneille, jotka haluavat saada tietokantojen sisällöstä enemmän irti kirjoittamalla itse omat kyselynsä. Kyselyjen avulla voi etsiä tietoa tietokannan sisältä ja luoda raportteja joilla saadaan kaivettua uusia huomioita tietokannan sisällöstä. Kurssi toimii myös hyvänä perehtymisenä tietokantoihin. 

MIKSI

Tulet  oppimaan SQL-kyselykielen salat tällä kurssilla!

MODULE 11: USING TABLE EXPRESSIONS

Previously in this course, you learned about using subqueries as an expression that returned results to an outer calling query. Like subqueries, table expressions are query expressions, but table expressions extend this idea by allowing you to name them and to work with their results as you would work with data in any valid relational table. Microsoft SQL Server supports four types of table expressions: derived tables, common table expression (CTEs), views, and inline table-valued functions (TVFs). In this module, you will learn to work with these forms of table expressions and learn how to use them to help create a modular approach to writing queries.
