MOC-20761 Querying Data with Transact-SQL

Selle kursuse põhieesmärk on anda õpilastele hea arusaamine Transact-SQL keelest mida kasutatakse kõigis SQL Serveriga seotud valdkondades – nimelt Andmebaasi administreerimises, andmebaasi arenduses ja ärianalüüsis. Nii on ka selle kursuse põhi-sihtrühm just andmebaasi administreerijad, arendajad ja ärianalüüsi spetsialistid.

Lisatasu eest ligipääs iseseisvale harjutuskeskkonnale Microsoft Labs Online (MLO). Loe siit, mis on MLO.

Sihtgrupp: The main purpose of the course is to give students a good understanding of the Transact-SQL language which is used by all SQL Server-related disciplines; namely, Database Administration, Database Development and Business Intelligence. As such, the primary target audience for this course is: Database Administrators, Database Developers and BI professionals.
