Základy jazyka SQL - práca s dotazmi

Jazyk SQL je príkazovo orientovaný, pričom príkazy jazyka SQL formulujeme pomocou klauzúl s príslušnými kľúčovými slovami a parametrami. Kľúčové slová tvoria obvykle v databázovom systéme vyhradené – rezervované slová, takže ich nesmieme používať ako názvy bežných databázových objektov. Klauzuly príkazov sa väčšinou musia zapisovať v správnom, predpísanom poradí.
