LU04a - Syntax of DML
Introduction
As we know, SQL*„ stands for Structured Query L**anguage. Consequently, It should come as no surprise that SQL is indeed consistently structured.
Every SQL query contains the three main commands select, from and where.

Where does not have to occur if there is no condition.
