Create conditions from the DSL

There are a few types of conditions, that can be created statically from the DSL. These are:

• plain SQL conditions, that allow you to phrase your own SQL string conditional expression

• Constant TRUE and FALSE conditional expressions
• Converting a BOOLEAN column to a condition

Connect conditions using boolean operators

Conditions can also be connected using boolean operators as will be discussed in a subsequent chapter.
