Spaces are generally ignored, i.e. the expression 1 + 1 is equivalent to 1+1.

When a column name contains a space, it must be enclosed in brackets:

String values must be enclosed within double quotes.

Any spaces, tabs, and newlines within the double quotes are considered a part of the value.

In certain situations, spaces are required, e.g. when using operators as they require at least a single enclosing space.
